Chapter 1. GENERAL

1-1 Features

The DCP301 is a general-purpose single-loop program controller for controlling temperature, pressure, flow rate and

other inputs.

G High accuracy achieved by multi-range input

Multi-range input allows you to choose between the following input types: thermocouple,

resistance temperature detector (RTD), dc voltage and dc current. Accuracy of ±0.1%FS±1

digit and a sampling cycle of 0.1s ensures consistently high-precision control.

G Wide range of control output types

A wide range of models supporting various control output types are available: relay time-

proportional output, position-proportional output, current output, voltage time-propor-

tional output, and heat/cool output.

On models other than heat-cool control output, you can also choose neural net-based

auto-tuning and smart-tuning for inhibiting overshoot, in addition 2 degrees of freedom

PID.

G Enhanced compatibility with PLC

12 external switch inputs (eight optional), three event outputs and five time event outputs

(optional) ensure compatibility with automating systems designed around a PLC core.

G Easy operation

PARA

Up to eight frequently changed parameter setups can be registered to the

tating recall of item setups.

Chapter 4. WIRING

4-1 Wiring Precautions

WARNING

Before connecting the DCP301 to the measurement target or external con-

trol circuits, make sure that the FG terminal is properly grounded (100Ω

max.).

Failure to do so might cause electric shock or fire.

Before wiring, or removing/mounting the DCP301, be sure to turn the power

OFF. Failure to do so might cause electric shock.

Do not touch electrically charged parts such as the power terminals. Doing

so might cause electric shock.

CAUTION

Wire the DCP301 properly according to predetermined standards. Also

wire the DCP301 using designed power leads according to recognized

installation methods.

Failure to do so might cause electric shock, fire or faulty operation.

Do not allow lead clippings, chips or water to enter the DCP301 case. Do-

ing so might cause fire or faulty operation.

Inputs to the current input terminals (31) and (33) on the DCP301 should

be within the current and voltage ranges listed in the specifications.

Failure to do so might cause electric shock or faulty operation.

Firmly tighten the terminal screws at the torque listed in the specifications.

Insufficient tightening of terminal screws might cause electric shock or fire.

Do not use unused terminals on the DCP301 as relay terminals.

Failure to do so might cause electric shock, fire or faulty operation.

We recommend attaching the terminal cover (sold separately) after wiring

the DCP301. Failure to do so might cause electric shock, fire or faulty op-

eration.

Use the relays on the DCP301 within the service life listed in the specifica-

tions.

Continued use of the relays after the recommended service life might cause

fire or faulty operation.

Use induced lighting surge preventive device if there is the risk of power

surges caused by lightning.

Failure to do might cause fire or faulty operation.

Handling Precautions

• Before wiring the DCP301, check the controller catalog No. and terminal Nos.

on the label on the rear of the body. After wiring the DCP301, be sure to check

the wiring for any mistakes.

• Maintain a distance of at least 50cm between I/O leads or communications

leads and the power lead. Also, do not pass these leads through the same

piping or wiring duct.

• When wiring with crimped terminals, take care to prevent contact with adjacent

terminals.

• When connecting the DCP301’s thermocouples in parallel to other controllers,

make sure that the total input impedance of the other controller is at least

1MΩ.

If the input impedance is less than 1MΩ, the DCP301 may not be able to detect

sensor disconnection.

• When inputting the DCP301’s I/O (parallel connection in case of input) to an A/

D converter or analog scanner, read data may fluctuate.

To prevent this, adopt one of the following measures.

(1) Use a low-speed, integrating type A/D converter.

(2) Insert an isolator without a switching power supply between the DCP301

and A/D converter.

(3) Average data on a personal computer when reading data.

(4) If possible, set a filter for the input.

• Provide the wiring for the instrument power supply with a mains power shutoff

switch within reach of the instrument operator.

• Provide the wiring for the instrument power supply with a delayed operation

type (T) 1A current rating, 250V voltage rating fuse. (IEC 127)

• Devices and systems to be connected to this unit must have the basic insula-

tion sufficient to withstand the maximum operating voltage levels of the power

supply and input/output parts.

4-2 Compensating Lead

In the case of thermocouple input, connect the bare thermocouple lead to the terminal. If the thermocouple is located

a long way from the DCP301 or the thermocouple is connected to a terminal, extend the connection using a compen-

sating lead and then connect to the terminal. Use shielded compensating leads only.

• For I/O other than thermocouples, use JCS-364 shielded instrument polyethylene insu-

lated vinyl sheath cable or equivalent product. (This is generally referred to “twisted

shielded cable for instruments.”) The following cables are recommended.

Fujikura Ltd.

2-core IPEV-S-0.9mm²x 1P

3-core ITEV-S-0.9mm²x 1T

Hitachi Cable Co. 2-core KPEV 0.9mm²x 1P

Handling Precautions

• When installing the DCP301 in locations subject to vibration or impact, be sure

to use round crimped terminals to prevent the lead from coming loose from the

terminal.

• When wiring with crimped terminals, take care to prevent contact with adjacent

terminals.

• The recommended tightening torque for the terminal screws is 0.78 to

0.98N•m.

• Use no-voltage contacts such as gold contacts whose small current can be

switched ON/OFF. On some relay contacts, the small current cannot be switched

ON/OFF. Use no-voltage contacts having a sufficient minimum switching ca-

pability with respect to the contact current and open voltage of the DCP301.

• When using a semiconductor (e.g. open-collector) as a no-voltage contact, use

a semiconductor whose contact terminal voltages at contact ON are 3V max.,

and whose leakage current at contact OFF is 0.1mA.

• External switch inputs on the DCP301/302 can be connected in parallel.

When connecting in parallel with other controllers, thoroughly check the condi-

tions of the other controller before configuring the control system.

■ Patterns

SP and time comprise the settings for a single segment in a pattern. Up to 30 segments

can be linked to create a broken-line whose vertical axis is SP and horizontal axis is time.

This system is called the “RAMP-X” system.

SP setting: Within range of SP limitter upper and lower limits

Timesetting: 0 to 99h, 59min or 0 to 99min, 59s

(Select the time unit in setup data C 6 4.)

SP is the point that corresponds to the time elapsed in the current segment on a straight

line made by jointing the start point (SP setting value of the previous segment) to an end

point (SP setting value of the current segment).

Accordingly, segments are categorized as follows:

• Rising ramp (rising ramp, rising tendency)

Previous segment SP setting value < current segment SP setting value

• Falling ramp (falling ramp, falling tendency)

Previous segment SP setting value > current segment SP setting value

• Soak (soak)

Previous segment SP setting value = current segment SP setting value

In the case of the No.1 segment, both the start and end points become the soak segment of

the No.1 segment SP setting values.

SP (other than No.1 segment) is calculated as by the following formula:

SP = (current segment SP setting value - previous segment SP setting value) x (current

segment elapsed time ÷ current segment time setting) + previous segment SP set-

ting

Time setting of current segment

Chapter 5. FUNCTIONS

■ Events 1 to 3

Events 1 to 3 are event configuration data. These are used after setting the event type,

event standby, hysteresis and ON delay time.

A total of three event types are available: PV type events, controller status events, and

time events.

■ PV type events

• Basic specifications

The following page shows event type PV, deviation, absolute value deviation, SP, MV

and MFB. In the figures, the thick lines show ON-OFF changes in state. The upper line

expresses the ON state, and the lower line the OFF state.

EV and H stand for event setting value and hysteresis, respectively. Output in the

READY state is OFF.

• Event standby

Events function as follows when event standby has been set to ON.

- If the controller is in the

state in the figure when changing from the READY to

the RUN mode and after restoring the power, operation is the same as when event

standby is set to OFF. The up-facing arrow in the figure indicates a change to ON,

and a down-facing arrow indicates a change to OFF.

- If the controller is outside the

state in the figure when changing from the READY

to the RUN mode and after restoring the power, the state is OFF. After entering the

state, the up-facing arrow in the figure indicates a change to ON, and a down-

facing arrow indicates a change to OFF.

• Event ON delay

The event No. to apply the delay to and the delay time can be set regardless of event

type. “Delay” functions to turn output ON when the event is continuously ON for the

preset delay time after the event OFF→ON condition is satisfied.

When event ON delay is combined with event standby, event standby must first be

canceled before event ON delay functions.

• Segment progression

- Output is OFF until the program progresses to the segment containing the event

setting.

- When the program progresses to the segment containing the event setting, event ON/

OFF operation is carried out according to the event setting value.

- The previous setting is valid until the program progresses to a segment containing a

new event setting.

For this reason, set as follows to disable the event set in the previous segment from a

certain segment onwards:

Direct action events: Upper limit value of event setting

Reverse action events: Lower limit value of event setting

Note, however, that some types of event turn ON even if events are set as shown

above.

- When the program has progressed to the No.1 segment by the cycle or pattern link

functions, the previous setting is disabled. Output is OFF unless the No.1 segment

contains an event setting.

• Other

On 5G output models, when setup data C 1 8 is set to 1, and SP output (programmer

functions) is selected, the MV direct/reverse event does not function.

Chapter 5. FUNCTIONS

■ Controller status events

Controller status events are turned ON and OFF according to the controller mode, alarm

status and other statuses.

Though the event standby function does not function, the ON delay function does.

Event setting values (operating point), hysteresis and event standby are not set.

• Basic operations

The following basic operation types are provided:

RUN+HOLD+FAST+END

READY

G.Soak standby

MANUAL

Auto-tuning executing

Constant-value operation

MFB estimated position control, sum of all alarms

PV range alarm

Controller alarms

Low battery voltage

Console setup in progress

Loader setup in progress

ADV

When the DCP301 reaches the state designated by the event type, the event is turned

ON. Otherwise, the event is OFF.

• Alarms

Alarms are divided into PV range alarm groups (alarm code Nos. 01 to 16) and control-

ler alarm groups (alarm code Nos. 70 to 99, and low battery voltage).

When the event type is set to the sum of all alarms, the alarm turns ON even if at least

one of the alarms occurs.

When the event type is set to PV range alarm, the alarm turns ON even if at least one of

the alarms in the PV range alarm group occurs.

When the event type is set to controller alarm, the alarm turns ON even if at least one

of the alarms in the controller alarm group occurs.

• ADV

This is ON for 1s after executing program advance. The event ON delay is disabled

and a delay is not applied.

■ Time events

When the event 1 to 3 type is set to time event, the event can be used in the same way

as time events 1 to 5. However, note that events 1 to 3 do not have segment No. event

functions.

Though the event standby function does not function, the ON delay function does.

Chapter 5. FUNCTIONS

■ PID set selection

• Eight sets of PID parameters, PID1 to PID8, are used for

control operation. When the PID set No. is set to each seg-

ment by designating the PID set segment, control output is

calculated by each of the PID parameters.

• There are two ways of selecting PID sets: by designating the

PID set segment and PID set auto-switching. The method

can be selected by setting setup data C 1 1.

PID set No.

setup are not displayed.

All SP ranges

are divided to

eight zones.

Zone 5

Zone 3

Zone 2

Zone 1

• By designation of PID set segment, the PID set No. is set for

each segment, and control output is calculated by each of the

PID parameters.

• By PID set auto-switching, the SP full-scale is divided into

eight zones according to the settings of C P . 1 1 to C P . 1 7,

and the PID constant to be used according to the SP value is

automatically selected to calculate the control output.

PID set automatic switching

■ G.Soak (guarantee soak)

G.Soak ON/OFF and G.Soak width can be set for each seg-

ment. The G.Soak time can also be set by the variable param-

eter G S . t item.

The G.Soak function ensures a segment execution time with

PV close to SP. G.Soak functions not only in soak segments

but also in ramp segments.

G.Soak width

At the segment start point, PV and SP are compared, and the

absolute value of the resulting deviation continues for the

G.Soak time or longer. When the absolute value is smaller than

the G.Soak width, operation of that segment is started.

Segment set time

Segment execution time

G.Soak standby time

Time

The controller is in the G.Soak standby state until this condi-

tion is satisfied, and the linear lamp on the left of the profile

display blinks. The operation state is the same as hold at the

segment start point (time is set to 0). However, note that in the

FAST mode, the controller does not enter the G.Soak standby

state even if G.Soak is set to ON. The G.Soak standby state

can also be canceled by external switch output. The following

cancel conditions can be selected by the setup date C 5 2 to

C 5 4 settings.

G.Soak at segment start point

(1) G.Soak cancel when external switch input contact is ON or

PV satisfies the G.Soak cancel conditions

(2) G.Soak cancel when external switch input contact is ON

and PV satisfies the G.Soak cancel conditions

Chapter 5. FUNCTIONS

■ PV start

SP pattern

If PV start is set in the program setup, PV is started by

regular RUN operation.

The first point where PV matches the SP in the program

pattern (including bias for both PV and SP) is searched

for, and operation is started from that point.

Current

PV value

Start point

Start point

However, note that if a matching point is not found, op-

eration is started from the beginning of segment 1.

When PV has started, event operating points and the time

of time events are automatically corrected. If the PV start

function is selected by setup data C 5 2 to C 5 4 settings

relating to external switch input, PV start can be executed

without setting PV start in the program setup.

(1)"

PV start points

PV start is valid for segments in the currently selected

program, and invalid for the segment at the pattern link

destination.

(1) PV starts at point A where the PV value first

crosses the SP pattern.

(1)' PV starts at point B where the PV value first

crosses the SP pattern.

(1)'' Point C of segment 1 is the PV start point

since there is no point where the PV value

crosses the SP value.

■ Cycle

The cycle function is for repeating operation from the No.1

segment of the program pattern to the final set segment

for a preset number of cycles. The number of cycles can

be set up to 9999.

(5)

Cycle 1

(4)

(3)

When a number of cycles “n” is set, the operation count

becomes “n+1”.

(2)

(1)

When executing cycle operation, operation at the end point

of the final segment is not carried out, and operation is

restarted with the settings of events 1 to 3 and time events

1 to 5 cleared. At this time, PV is not started and opera-

tion starts from the No.1 segment even if PV start is set.

Time

If the SPs at the pattern start and end points do not match,

the SP changes in a stepped manner during cycle opera-

tion.

Chapter 5. FUNCTIONS

■ Pattern link

Program No.2 pattern-linked to program No.1

Program No.1

“pattern link” is a function for linking patterns together.

The link destination program No. is set by the pattern

link item.

When the pattern link item is set to 0 (initial setting),

patterns are not linked. When the No. of the current pro-

gram itself is set to the pattern link item, this creates an

endless loop.

Time

If the SPs at the link source end point and the link desti-

nation start point do not match, the SP changes in a

stepped manner during link operation.

Program No.2

Time

When cycle operation has been set, the pattern link func-

tion works after cycle operation has ended. After pattern

link operation ends, operation begins from the No.1 seg-

ment of the link destination pattern, so operation is re-

started with the settings of events 1 to 3 and time events

1 to 5 cleared.

If PV start is programmed to the link destination pattern,

the PV start function operates after the link is made.

After the link has been made, PID operation is not ini-

tialized, and is continued.

I Mode transition operations

The following describes mode transition operations.

Though “program end” is not an operation, it is described below as it is a factor in mode

transition.

I RUN

This operation involves shifting to the RUN mode from the READY, HOLD or FAST

modes. To shift from the READY mode to the RUN mode, the DCP301 must be in the

basic display state even in key, external switch input or communication operations.

I HOLD

This operation involves shifting to the HOLD mode from the RUN or FAST modes.

The HOLD mode is not available in the constant-value operation mode.

I RESET

This operation involves shifting to the READY mode from the RUN, HOLD, FAST or

END modes.

In the program operation mode, this mode includes returning to the No.1 segment.

I ADV

This operation involves advancing one segment in the READY, RUN, HOLD or FAST

modes.

The ADV mode is not available in the constant-value operation mode.

I FAST

This operation involves shifting to the FAST mode from the RUN or HOLD modes.

The FAST mode is not available in the constant-value operation mode.

I AUTO

This operation involves shifting to the AUTO mode from the MANUAL mode.

This operation involves shifting to the MANUAL mode from the AUTO mode.

I MANUAL

When the DCP301 enters the MANUAL mode, the basic display state changes as fol-

lows.

- When controller functions are selected, PV and output value (%) are displayed.

- When programmer functions are selected, PV and SP are displayed.

When the DCP301 enters the MANUAL mode from the AUTO mode by external switch

inputs or communications, the display changes to the basic display state even in the pa-

rameter setup or program setup states.

I Program end

When operation progresses in the RUN or FAST modes in the program operation mode,

or when the segment has been advanced in the ADV mode, the program ends when all

end points in the program setup including cycles and pattern links have been reached.

You can select in the setup setting in which of the READY or END modes program

operation ends.

The program does not end in the constant-value operation mode.

5-4 Controller and Programmer

On 5G output models (output catalog No. appended with 5G), you can choose between use as a controller or a

programmer. Set this in setup data C 1 8. You can also choose between controller or programmer functions even if

the DCP301 is used for program operation or constant-value operation.

The DCP301 is limited to use as a controller at all times on other models.

I Controller

When the DCP301 is used as a controller, PID control operation is carried out according

to PV, SP AND PID setting values, and the resulting manipulated variable (MV) is out-

put as an analog output.

ON-OFF control, heat/cool PID control and 3-position-proportional is also possible de-

pending on the type of output supported by the model of DCP301.

In the MANUAL mode, the MV can be incremented or decremented in the basic display

state by the console keys.

DCP301 controller

Controlled system

I Programmer

When the DCP301 is used as a programmer, PID control operation is not carried out, and

the SP is output in the scaled 4 to 20mA range.

In the MANUAL mode, the SP can be incremented or decremented in the basic display

state by the console keys.

(However, when the total time for the PID parameter of the PID set in use is set to “0”, a

sudden change in output occurs.)

G Programmer functions

On 5G output models, when programmer functions are in operation with setup data C 18

Output changes when shifting from the AUTO to the MANUAL mode are bumpless

regardless of setup data C 15 setting. When shifting from the MANUAL to the AUTO

mode, the SP becomes the program pattern SP, which results in a sudden change in out-

put.

G Auto-tuning (AT)

When operating in the AUTO mode in either of the RUN, HOLD, FAST or END modes,

setting values can be automatically written to the PID set in use by auto-tuning (AT). The

following can be selected by variable parameter A t setting.

0:AT is disabled.

1:General AT is executed.

2:Overshoot-inhibited AT is executed.

3:AT by neural net is executed.

• Auto-tuning does not function when programmer functions are selected on 3D or 5K

heat/cool output models and 5G output models.

• During execution of auto-tuning, progress of program operation time stops. Accord-

ingly, the controller is in a similar state to the HOLD mode even in the RUN or FAST

modes.

6-11

Chapter 6. OPERATION

• Auto-tuning in all instances involves calculating the downtime and critical sensitivity

of the line according to two limit cycles and PID values according to suitable charac-

teristic equations for each, and automatically writing these PID values.

• During execution of auto-tuning, PV fluctuates according to fluctuations in MV. Be-

fore executing auto-tuning, make sure that fluctuations in PV will not cause controller

trouble.

• Normally, suitable values are written by setting variable parameter At setting to 1 or 3.

However, when executing auto-tuning on a line that easily overshoots, either set to 2,

or also use smart-tuning for carrying out overshoot inhibit control. Setting to 3 ex-

ecutes AT by neural net so that the suitable value is calculated for wider range applica-

tions.

• The point at which output at auto-tuning is inverted (lower limit to upper limit, and

vice versa) is determined as follows from SP and PV at start of auto-tuning.

At start

At SP=PV operation

PV>SP

2/3

PV<SP

Time

Normal end

• Auto-tuning can be started by

, external switch inputs and communications. Dur-

ing auto-tuning, the AT LED blinks.

• If one or more of the following conditions occurs during auto-tuning, auto-tuning is

canceled without PID constants being written, and the AT LED goes out.

- Cancel by

- Cancel by external switch input

- Cancel by communications

- Change in mode (shift to MANUAL mode or READY mode)

- Execution of automatic motor valve opening adjustment on 2G output models

- When variable parameter A t setting is changed to “0”

- When input 1 becomes out-of-range

Handling Precautions

• Auto-tuning will not function properly unless the control target is connected.

• The time from start to end of auto-tuning varies according to the control target.

• When auto-tuning is executed, control is stopped, OFF and ON outputs are

switched in the case of relay output and voltage output, and the manipulated

variable upper and lower limits of the currently selected PID set are switched

several times in the case of current output and position proportional output. If

this causes controller trouble, manually set the PID value.

• Sometimes a suitable PID value cannot be obtained depending on the control

target. If this happens, manually set the PID value.

Chapter 7. PARAMETER SETUP

■ O T L (MV change limit)

The MV is increased or decreased by the same value so that the output change is taken as

the limit setting value when the output change (%) after PID operation is greater than this

limit setting.

The following example shows the actual change in MV when the MV changes from 20%

to 22% with the change limit setting at 0.5%. MV is output at 0.5% setting value incre-

ments every 0.1s, and reaches 22% in 0.4s.

t + 0.1 t + 0.2 t + 0.3 t + 0.4

■ I O U t (PID operation initial MV)

PID operation is started in the following cases using the I O U t setting value:

• When the mode changes from READY AUTO to RUN AUTO

• When the power is turned ON in the RUN AUTO (or HOLD, FAST, END AUTO)

mode

• At completion of auto-tuning

As the PV, SP and PID parameters settings bear a relation to PID operation, the first MV

resulting from PID operation will not necessarily match the I O U t setting value.

■ R P I D (PID operation initialization)

When SP changes suddenly by ADV (advance) operation, rate action in PID operation

may cause the MV in the operation to change excessively. For this reason, excessive

changes can be suppressed by initializing PID operation.

However, as initialization of PID operation may result in lost continuity, initialization

may adversely influence PID operation depending on the circumstances in which the

controller is being used.

Initialization ON/OFF and conditions can be selected by the R P I D setting.

Chapter 7. PARAMETER SETUP

■ S t (smart-tuning method selection)

0: Smart-tuning is disabled.

1: The brake value is fixed to inhibit overshoot.

2: Overshoot is inhibited while automatically reviewing the brake value.

• When the control direction is set to reverse action, overshoot is inhibited. When set to

direct action, undershoot is inhibited. Both functions are referred to collectively as

“overshoot inhibit.”

When set to 1, the value of PID parameter setting item B R is used as it is to inhibit

overshoot.

When set to 2, the value of B R is reviewed at each rise (reverse action) or fall (direct

action, and overshoot is inhibited while the value is automatically rewritten.

Review is executed only in the direction in which the B R value is increased (overshoot

inhibit effect becomes more apparent).

When operation is carried out for a long time with this parameter set to 2, overshoot

inhibit may function too strongly, and it may take a long time to arrive at SP. So, when

overshoot disappears, note down the B R value at that time, set S T to 1, and reset the

B R value to the noted down value.

• The AT LED lights while reviewing the B R value when set to 2.

• Do not set to 2 when normal control is not being carried out due to inappropriate tuning

of the PID constant, for example.

Also, hunting is more likely to occur when B R is set to a large value on quick-starting

lines. Set the B R value to 0 then to 2.

• On heat/cool models, smart-tuning does not function.

■ 2 P I D (2 degrees of freedom)

0: 2 degrees of freedom is disabled.

1: 2 degrees of freedom is enabled.

• 2 degrees of freedom is a function for improving the response to disturbance during

setup without losing conventional characteristics at rise (or fall).

When set to 1, optimum PID constants can be set individually for inhibiting distur-

bance in addition to conventional the PID constant.

These constants are set automatically during AT execution, and is memorized. They

can also be set and changed independently.

In particular, on 2G output models, suppressing changes in MV to lessen the frequency

of motor operation during setup, and manually applying weak PID differential for in-

hibiting disturbance to lengthen service life, for example, proves effective.

• These PID are switched automatically by applying fuzzy rules on the slope between

deviation and PV.

• When I (reset time) is set to 0, control is carried out without integration in all states

regardless of the setting value of D I (disturbance inhibit reset time).

• On heat/cool models, 2 degrees of freedom does not function.

• Position-proportional control dead zone

On 2G output models, a dead zone between the motor open and motor closed positions is

set.

As a general guideline, the minimum value is the value where this dead zone changes to

stop motor hunting once a fixed value set to manual output is being output.

If this value is set without any margin, the motor will be operating at all times, which will

considerably shorten its service life.

The factory setting is 5%. Use this as a guideline, and take the control results and motor

service life into consideration when setting the dead zone.

■ M .-C (motor control method selection)

0: MFB control (conventional) + estimated position control

1: MFB control (conventional) only

2: Estimated position control only

• 0: MFB control (conventional) + estimated position control

• When MFB (Motor Feed Back) input is normal, the motor position is controlled by the

actually measured MFB.

• When MFB input is in error, the motor position is controlled by an estimated MFB

value. This state is referred to as “estimated position control state.”

For example, when the motor rotates at a position where the feedback potentiometer

has deteriorated, MFB input changes suddenly. This sudden change is detected as an

error, and the correct MFB position is estimated. The motor position is also controlled

by the estimated MFB value when the MFB disconnected alarm has occurred.

• In the estimated position control state, an error will inevitably occur between the actual

motor valve opening and estimated MFB value.

So, set the closed-side relay to ON at all times when output (MV) ≤ 0.0%, and the

open-side relay to ON at all times when MV ≥ 100.0% to set the motor to a fully-open

or fully-closed state to compensate this error.

However, note that this error is not compensated when MV is limited to within 0.1 to

99.9% by the output limitter, or when MV is 0.0% or less or 100% or more due to the

control state.

• The following are probable causes when estimated position control is likely to be car-

ried out:

- Defective motor valve opening adjustment

- Deteriorated feedback potentiometer, insufficient resolution

- Defective MFB wiring.

• 1: MFB control (conventional) only

• When this setting is used, conventional MFB control is carried out. When the MFB

disconnected alarm occurs, the MFB value is regarded as 150.0%, and the closed-side

relay is ON at all times.

• 2: Estimated position control only

• When this setting is used, control is in the estimated position control state at all times,

and the motor position is controlled by the estimated MFB value regardless of the state

of MFB wiring.

• When this setting is used, enter the correct M .-t item.

• The MFB disconnected alarm does not occur.

• The error between actual motor valve opening and estimated MFB value is compen-

sated by forcibly continuing motor operation in the closed or open directions when MV

is 0.0% and 100%.

■ Description of event configuration data

■ E D 1 (event 1 standby)

■ E D 2 (event 2 standby)

■ E D 3 (event 3 standby)

0: Standby OFF

1: Standby ON

• When set to standby ON, event output becomes OFF if the controller is in the standby

state even if the condition for turning event output ON is satisfied.

• The controller enters the standby state in the following instances:

- When in the READY mode

- When shifting from the READY to the RUN mode

- When the power is turned ON

• The standby state is canceled in the following instances:

- When the condition for turning event output OFF (not including the hysteresis pe-

riod) is satisfied in one of the RUN, HOLD or FAST modes

- When set to standby OFF

• In the following example, PV event direct, operating point 500°C, hysteresis 10°C and

standby ON are set. When the mode changes from READY to the RUN mode at PV

550°C, the controller enters the standby state, so event output is turned OFF.

• Standby functions only when the event type is set to PV type event, and does not

function when set to time event type or controller status type.

■ D L 1 (event 1 ON delay time)

■ D L 2 (event 2 ON delay time)

■ D L 3 (event 3 ON delay time)

• The ON delay time is processed after completing all processes up to event output standby

ON/OFF. Event output is turned ON when more than the ON delay time has elapsed

with the condition for turning event output ON satisfied.

• When the event type is set to ADV, the ON delay function does not operate whatever

value is set as the ON delay time.

• ON delay time is processed as follows.

Chapter 7. PARAMETER SETUP

■ Description of setup data settings

■ C 0 7 (input 1 square root extraction dropout)

• Generally, the differential pressure detected by an orifice on a differential pressure

type flowmeter, is proportional to the square of the flowrate. For this reason, square

root extraction is carried out when uniform signals are required.

When input for square root extraction is the dropout value set by C 0 7 or less, output

from square root extraction processing can be set to 0%.

• When C 0 7 is set to 1, square root extraction is not carried out.

Output after square root

extraction (Y)

Y=(X/100)^1/2x 100

Input (X)

Dropout value

(variable in range 0.1 to 10.0%)

• Square root extraction is carried within the range 0.0 to 100.0%. In the ranges -10.0 to

0.0% and 100.0 to 110.0%, regular scaling is carried out.

■ C 0 q (SP1 lower limit)

■ C 1 0 (SP1 upper limit)

• This is a program setup pattern item, and functions as a limitter when setting or chang-

ing SP.

• In the program operation mode, this functions as a limitter on the value obtained by

adding the SP set to the program to the SP bias (variable parameter). The result of this

operation is taken as SP.

• This functions as a limitter when setting or changing the SP in constant-value data

setup.

• In the constant-value operation mode, this functions as a limitter on the value obtained

by adding the SP set to the constant-value operation data to the SP bias (variable pa-

rameter). The result of this operation is taken as SP.

■ C 4 7 (auxiliary output 1 lower limit)

■ C 4 8 (auxiliary output 1 upper limit)

■ C 5 0 (auxiliary output 2 lower limit)

■ C 5 1 (auxiliary output 2 upper limit)

• This is the scaling setting for auxiliary output. The values of the upper limit setting and

lower limit setting can also be inverted.

• In the following example, the type is set to MV at auxiliary input 1. 12mA is output

when MV is 100% and 20mA is output when MV is 0%. In the following figure, MV is

200% when virtually calculated at 4mA.

Accordingly, the setting of C 4 7 and C 4 8 become 200.0 and 0.0, respectively.

Chapter 7. PARAMETER SETUP

■ C 6 5 (time display)

0: Remaining segment time

1: Total operation time

• This selects the time display in the basic display state in the program operation mode.

• When set to 0, in the READY mode, the time setting value of the currently selected

segment is displayed.

• When set to 0, in the RUN, HOLD, FAST or END modes, the remaining time for the

currently executing segment is displayed after being rounded down.

For example, if the remaining time is 1h, 30min, 59s when the time unit is set to “h:min”,

the time display is “1 .3 0”.

• When set to 1, in the READY mode, the time display is “0 .0 0”.

• When set to 1, in the RUN, HOLD, FAST or END modes, the time it takes to shift from

the READY to the RUN mode is displayed after being round down. Also, after

“q q .5 q” the time display changes to “0 .0 0”.

For example, if the remaining time is 101h, 30min, 59s when the total operation time is

set to “h:min”, the time display is “1 .3 0”.

• In the FAST mode, the time display changes according to the FAST scale if this pa-

rameter is set to either 0 or 1.

■ C 6 6 (PV display)

This selects PV display in the basic display state. You can select between numerical

display or no display at all. The setting of this parameter does not influence PV-related

input processing, PID operation, event output, auxiliary output and alarm display.

Also, to eliminate PV alarm display or PV alarm event output, select the thermocouple

range by the input range to short-circuit the input terminals.

■ C 7 2 (cold junction compensation)

0: Compensated internally

1: Compensated externally

• This selects how thermocouple cold junctions are to be compensated.

• When set to 1, carry out 0°C compensation by an ice box, for example.

■ C 7 4 (voltage time-proportional output system)

0: Input ON again enabled within time-proportional cycle

1: Input ON again disabled within time-proportional cycle

• This selects whether or not to turn output ON again even if output is OFF when the

results of PID operation have changed during the time-proportional cycle (cycle time).

• The figure below shows each of these differences.

Chapter 7. PARAMETER SETUP

■ C 7 8 (voltage output 1 adjustment)

■ C 7 q (voltage output 2 adjustment)

When driving an SSR by voltage time-proportional output, the output voltage of the

controller must be within the input rated voltage (optimum ignition voltage) of the SSR.

On the DCP301, a newly developed variable output system is utilized that enables output

of the optimum ignition voltage even when driving two or more SSRs.

This system sets the optimum current value on the controller so that the optimum ignition

voltage with respect to the internal impedance of the SSR side can be obtained.

The following shows equivalent circuits and related formulas.

Chapter 7. PARAMETER SETUP

(5) Example: Using Yamatake Corporation’s PGM

VSSR : 3 to 6V

: 260Ω ± 5%

: 0.8 to 1.3V

• What value should I_Obe set to when connecting one PGM?

As shown in the figure on the right, a fixed-current system is used for the voltage

output of this controller. The fixed current can be calculated as follows from the

input voltage range of PGM.

8.9mA ≤ 1 ≤ 17.2mA

IMIN x ZMIN + VD/MIN > 3

IMIN > 8.9mA

IMAX x ZMAX + VD/MAX < 6

IMAX < 17.2mA

DCP301

PGM

• How many PGMs can be connected?

A current of 8.9mA or more must flow to a single PGM. On the other hand, the

maximum current of the controller is 22.0mA. Accordingly, two PGMs can be con-

nected in parallel.

In the case of a series connection, due to the maximum output current (22.0mA)

and allowable load resistance (600Ω), the maximum voltage that can be applied to

a load becomes 13.2V (22.0mA x 600Ω).

When a current of 8.9mA flows to a PGM, the maximum voltage at both of its input

terminals becomes 3.7V.

0.0089 x 260 x 1.05 + 1.3 = 3.7V

Accordingly, 13.2 ÷ 3.7 = 3.56, which means that three PGMs can be connected in

series.

The above calculation assumes operation in the worst conditions. For example,

even if four PGMs are connected in series, they should operate normally if a volt-

age of 3V or more is applied to each of the PGMs in a voltage ON state.

■ C q 0 (Special functions)

• Normally set to 0.

• In the case of setup 102, current output (including heat-cool output) 0 to 100% for the

control output becomes 0 to 20mA. Note, however, that at 0% or less, the current is

0mA.

At output 1mA or less, accuracy is ±0.5%.

• In the case of setup 103, current output (including heat-cool output) and auxiliary out-

put 0 to 100% for the control output becomes 0 to 20mA. Note, however, that at 0% or

less, the current is 0mA.

At output 1mA or less, accuracy is ±0.5%.

• When the input 1 range type (C 0 3) is an RTD in setup 241, Zener barrier adjustment

(C 9 1) is displayed.

(4) Press

to display the difference (A—B) between the resistances of the Zener bar-

rier connected to leads A and B on the lower display.

(6) Press

to set the DCP301 to the basic display state.

(7) Turn the power OFF, and remove the short across A and B.

Handling Precautions

• The resistance error of the Zener barrier connected to leads A and B cannot be

adjusted unless it is 20Ω or less.

• This adjustment is not required when a Zener barrier and an input other than

an RTD are not used.

• Once the Zener barrier has been adjusted, compensation is carried out on the

Zener barrier. When using on an RTD without a Zener barrier, re-adjust without

the Zener barrier.

■ C 9 3 (CPL communications port selection)

• When set to 0, CPL communications from the loader jack is not possible. In this case,

CPL communications is possible from the addon terminal under setup C 8 4 and C 8 5

communications conditions if the controller model supports CPL communications.

• When set to 1 to 15, CPL communications from the loader jack is not possible, and the

C 9 3 setting becomes the CPL communications address.

Communications conditions are also 4800bps, even parity and 1 stop bit.

In this case, CPL communications is not possible from the addon terminal even if the

controller model supports CPL communications.

• Use the special cable to connect the RS-232C port on the personal computer and the

loader jack on the equipment.

• When the setup C 0 0 (ROM revision) setting indication is 0 or 1, the setup C 9 3

setting indication cannot be set at “---”.

Also, communications from the loader jack is not possible.

Chapter 8. PROGRAM SETUP

8-1 Program Setup

Programs can be set up when the DCP301 is in the basic display state. This is sometimes referred to as “program-

ming” in this manual.

DISP

If the DCP301 is not in the basic display state, press

to set the controller to the basic display state.

Programming can be carried out more easily if the details of the setup are entered to a program chart before starting

programming.

■ How to enter program setup

■ Key operation

FUNC

PROG

Press

in the basic display state to enter program setup.

In the program setup state, the PRG LED on the console lights, and the decimal points in

the program No. display and segment No. display light. However, note that the DCP301

does not enter the program setup state in the following cases:

- When in the constant-value operation mode (when constant-value operation data

M . O d e setting is 1)

- When key lock is active (variable parameter L O C is set to 2 or 4)

Also, the setup cannot be changed even if the DCP301 is in the program setup in the

following case:

- When the program is protected (variable parameter P R t C is set to 1)

■ Display start items

When the DCP301 enters the program setup state, display starts from the program No.

and the segment No. pattern item.

■ Selecting the program No. to set up

There are two ways of selecting the program No. to set up.

- Selecting the program No. before entering program setup

- Selecting the program No. after entering program setup

■ Selecting the program No. before entering program setup

PROG

Chapter 8. PROGRAM SETUP

■ Selecting the program No. after entering program setup (continued)

When you select the program No. by this method, the display changes to segment No.1

and the pattern item on the programming map.

This method can be used, for example, to select a program No. to set up a program other

than the No. being operated in the RUN mode. It can also be used to select a program No.

to set up a program other than the currently selected No. by external switch input.
