2.0 Safety
Read this manual in its entirety before operating the POWERPOD-400 Power Supply/Totalizer. The
POWERPOD-400 is designed to operate with most Teledyne Hastings Instruments (THI) flow controllers
and meters. Read all wiring and power hookup instructions and understand the requirements prior to
using another manufacturer’s products with the POWERPOD-400. Insure that any product being
interfaced with the POWERPOD-400 is wired according to prevailing local safety and operational
standards before operating.
The following symbols and terms may be found on THI products and/or in THI manuals and indicate
important information.
When found on the device, this symbol indicates that the operator should refer to
the manual for important instructions on the proper use of this device. When found
in the manual, this symbol indicates that the reader should understand the
implications contained in the text before operating the device.
This symbol indicates that a shock hazard may be present. Read the instruction
manual carefully and insure that the device is wired properly and that all settings
have been checked prior to applying power to the device.
The WARNING label indicates important information that should be heeded for safe and proper
performance of the device.
The label, CAUTION, is used to indicate that damage to the power supply or equipment
connected to it could occur if directions are not followed. Warranty could be invalidated if the
instructions in this manual are not followed.

3.0 Features
The POWERPOD-400 serves as a convenient control center that can be rack-mounted using standard half-
rack hardware or can be used as a bench top unit. The POWERPOD-400 is equipped with a 4 X 20
character, vacuum fluorescent display (VFD). The display emulates a liquid crystal display in its
command structure but the VFD gives the unit a greater viewing angle and better visibility than available
with most conventional LED or LCD displays. The display can be set to four different brightness levels.
Use a lower brightness setting to extend the already long expected life time of the display. Use brighter
settings for viewing areas where ambient light may be too bright or cause glare, or where greater viewing
distances are required.
Most features are accessible via the membrane keys on the front panel. Consult the section on each
function to check its availability. Operators are guided through the many features and options by selecting
their choices from an intuitive menu structure.
FRONT PANEL LOCKOUT
The Front Panel Lockout function is only available through serial communication. Manual
Overrides remain available during Lockout via a minimum number of keystrokes using
dedicated keys for this purpose and allow any command setting to be overridden in either the
high (open) or low (closed) state.
ANALOG RANGE SELECTION
Analog signal and control ranges are operator selectable. The operator can choose between three different
DC ranges:
0 -5 VDC, 0-10 VDC or 4 -20 mA.
A fifteen (15) pin, high density, sub-miniature, D-type connector is provided for separate monitoring of
each channel’s analog transducer signal.
CAUTION: Consult the appropriate section for limits to the loading of these signals.
SERIAL COMMUNICATION
The POWERPOD-400 comes equipped with standard RS-232 and RS-485, serial communication. Most
functions, features, signals and alarms are accessible and modifiable via any remote computer.
The following commands are manual commands only:
OPEN, AUTO and CLOSE.
The status of these settings can be read via serial communication but they cannot be changed
except manually, from the front panel.

POWER SELECTION
Power input is switchable between 100 VAC, 115 VAC and 230VAC (50 or 60 Hz) via
the rear panel. For the safety of the operator as well as the device, the correct power
level should be selected prior to connecting to the power mains. See the table
“POWERPOD-400 Specifications” in section 3.0 for the proper fusing when changing
power settings.
RATIO CONTROL
Ratio control is possible between channels using a familiar master/slave configuration. Channel one
(1) must be enabled as the master channel. Any combination of the remaining channels is possible
for slave channel assignment.
TOTALIZER
A Totalizer function is present for each channel with the capability of counting down from a set
point, counting up to a set point or continuous count up. The maximum count is ±999999 units.
When the set points are reached, a memory flag for each set point is set to a digital ‘1’ indicating a
Boolean ‘true’ value. The Totalizer set point flags must be polled via digital communication to be
read. Each flow channel has one low-limit and one high-limit set point available. These alarms are
available via open-collector, opto-isolated outputs on the rear panel as well as serial
communication.
POWER OUTAGES AND THE OVERRIDE CONDITION
In the event of a power outage, even one of short duration, the POWERPOD-400 is
designed to conduct a software reset. During the period of time in which the reset is
occurring, it will not accept or respond to any commands either manually or digitally
until the reset process is completed. After said reset, the POWERPOD-400 will have
remembered all previously entered set-points but all channels are designed to come up
in the “Override-CLOSEd” condition. For meters, this should have no affect on their
behavior. All analog-only, THI, flow controllers with normally-closed (NC) valves will
close and remain closed until operator intervention manually returns selected channels’
Override condition back to the AUTO mode.
For all other controllers, this means that the control signal (pins 5 to 14) of J1 through
J4 will return to the previously set level. For controllers not taking advantage of the
Override function (pin 8), these controllers will return to their normal, preset operating
condition unless other intermediary steps are undertaken. Controllers that are making
use of the override function (Pin 8) and have normally-open valves will be driven to the
fully open condition.

8.0 Manual Operation
8.1.POWER ON/OFF
The Power On switch, item 1 in rear panel drawing, is located in the upper right corner of the
rear panel. Insure that the proper power setting is selected prior to turning the power on. See
the Power section of WIRING THE POWERPOD-400, above.
8.2.CHANGING THE COMMAND SET POINT
Channel two (2), example shown.
Press the desired CHANNEL # key. An asterisk appears in the first space on the line representing the
selected channel. The meter display is immediately replaced with the current set point. Pressing a
number key begins the editing process. The cursor lands on the channel set point to be edited, and the
new command is entered with the most significant bit (MSB) first. The set point is filled in from left to
right on the display. When entering a new set point, you must use the decimal key when it has been
used in setting the SPAN. Pressing ENTER completes the editing process. The old command is not
changed until the ENTER key is actuated. Hitting the ESCape button at any time prior to the ENTER
key will return the display to its previous state without any changes being made. This command will not
be applied to the output until the channel is set for AUTO operation. See Setting a Channel to AUTO
Control.
8.3.OVERRIDE OPEN
Press the desired CHANNEL # key. An asterisk appears in the first space on the line representing the
selected channel. The meter display is immediately replaced with the current set point. Pressing the
OPEN key results in the application of +15 VDC to pin number eight (8) of the corresponding 15 pin
Sub-D connector and returns the previously programmed metering function to the display.
8.4.OVERRIDE CLOSED
Press the desired CHANNEL # key. An asterisk appears in the first space on the line representing the
selected channel. The meter display is immediately replaced with the current set point. Pressing the
CLOSE key results in the application of -15 VDC to pin number eight (8) of the corresponding 15 pin
Sub-D connector and returns the previously programmed metering function to the display.

8.5.SETTING A CHANNEL TO AUTO CONTROL
Press the desired CHANNEL # key. An asterisk appears in the first space on the line representing the
selected channel. The meter display is immediately replaced with the current set point. Pressing the
AUTO key causes pin number eight (8) of the 15 pin Sub-D connector to float and returns the previously
programmed metering function to the display. Pin 14 signal levels are now available for control.
8.6.SETTING A CHANNEL TO DIRECTLY METER INCOMING SIGNALS
Press the MODE key. The MODE menu appears in the display. To select METER, press 1, and then
ENTER. The METER menu allows the selection of the desired channel. Press the number key that
corresponds with the desired channel followed by ENTER. The previously programmed display returns
with the selected channel reading the signal between pins 5 and 6 of the corresponding channel’s 15 pin
D-connector (J1 – J4).
8.7.SETTING A CHANNEL TO DISPLAY THE TOTALIZER FUNCTION
The POWERPOD-400 provides an integrated (Riemann Sum) value of the incoming signal for each
channel.
T = Total
⎧
⎫
⎪
⎪
⎨
⎪

⎬
f = Fractional Signal Factor

T = ( f *C * f ), where:
∑

C = CAL value or Span Value
⎪
⎪
⎪
⎪
⎭
fI = Fractional Time Interval
⎩
Each channel samples the incoming signal at a rate
corresponding to the preset A/D conversion rate in Hz. At
each sampling interval, the TOTALIZER function multiplies
the average signal, as a fraction of the full-scale value (5v, 10v
or 20 mA), times the span, or cal, value. This results in a rate
for that interval. Next, a time element factor is determined
according to the flow rate programmed for that channel as
follows.
For a time element of seconds, the factor is 1/10.
For minutes, the factor is 1/600.
Hours use a factor of 1/36000.
Each calculation is summed and stored for a TOTAL value.

Example (See Graph):
A linear flow transducer with a DC output of 0 to 5 volts is calibrated for a maximum flow of 25 SLH.
The transducer is connected to one channel of a POWERPOD-400 which is CAL’d to read 25.000 at 5
volts input and has been programmed to display rate in SLH. The transducer is sending a constant 1.000-
volt signal to the POWERPOD-400. What is the total flow after 40 minutes?
During one sampling interval, the TOTALIZER reads the one-volt signal and calculates the fraction of the
possible full-scale value.
1 volt/5 volts or 0.20
The fractional signal value is multiplied times the CAL value
1/5 * 25 = 5
Then, because the channel’s programmed rate is in SLH (standard liters per hour), a factor of 1/3600 is
applied to the result.
5 * 1/36000 = 1.389 x 10^-4 standard liters per sampling interval.
A constant signal received over a 40 minute time period would amount to 40 minutes * 60 seconds * 10
samples per second = 24000 samples. The TOTAL would be
2.400 E03 * 1.389 E-04 = 3 1/3 Std Liters.

10.8. CALIBRATING A CHANNEL TO ITS INCOMING SIGNALS
The POWERPOD-400 is designed to accept the input from almost any transducer that operates in the
ranges of zero to five volts, zero to ten volts or four to twenty milliamps. In most cases, transducers are
capable of having their minimum signal and maximum signal adjusted to correspond with the minimum
(ZERO) and maximum (SPAN) unit-of-measure that they are designed to reflect.
For example:
A transducer designed to output 0 volts while reading a temperature of 0 degrees centigrade and output 5
volts while reading 100 degrees centigrade is connected to channel one of the POWERPOD-400.
In actuality, the transducer is sending -0.23 volts at 0 degrees and 5.11 volts at 100 degrees. By zeroing
channel one of the POWERPOD-400 while reading the low signal from the transducer, the display will be
000.0 when the temperature is 0°C. Like wise, by setting the CAL value to 100.0 while reading the 5.11
volt signal causes the POWERPOD-400 to display 100.0 when the temperature is actually 100°C.
This procedure will not account for any non-linearity in any transducer’s output. That is, the
accuracy/calibration of any transducer must be independently set, checked and verified before
connecting to the POWERPOD-400, or, the transducer/ POWERPOD-400 combination must be
calibrated together as a system, if the accuracy of the whole system is to be known.
10.8.1. Resetting the Zero Only
While the SETUP/CAL menu is being displayed and after making a selection from the CHANNEL
SELECT menu, select CALIBRATE by pressing the number 7 key followed by ENTER, then choose
ZERO ONLY by pressing the number 1 key and ENTER. The ZERO menu will be displayed which also
displays the selected channel number and the signal being received. If this signal is an acceptable signal
for zero, press the ENTER key to accept it. If the indicated signal is not an acceptable level for reading
zero, the operator has an opportunity at this stage to correct any problems while reading the incoming
signal before pressing the ENTER key and accepting it. Alternatively, the operator can press ESC to exit
the SETUP/CAL mode and return to it later. After accepting the displayed signal level as the zero point,
the display returns to its previously programmed settings. See Appendix D.
10.8.2. Resetting the Span Only
After selecting a channel in the CHANNEL SELECT portion of the SETUP/CAL menu, press 7 +
ENTER to select CALIBRATE. SPAN ONLY is selected by pressing number 3 + ENTER. The
SPAN window is displayed which contains the chosen channel and the incoming signal on that channel.
If the displayed signal is an acceptable full range value, press ENTER to accept it. The previously
programmed display returns with the selected channel now displaying the CAL’d value. If the incoming
164-122012 PowerPOD 400
Page 26 of 42
Download from Www.Somanuals.com. All Manuals Search And Download.
signal is not an acceptable full range value, the operator has an opportunity to correct any problems at this
stage prior to pressing ENTER. Alternatively, the operator can press ESC to exit SETUP/CAL and
return later. See Appendix D.
10.8.3. Resetting Zero and Span
Should it be required to zero and set a new span value for a given channel, The menu option is provided
that will present the programmer with the zero menu first, followed by the span, or cal, menu. After
selecting a channel in the CHANNEL SELECT portion of the SETUP/CAL menu, press the number 7
key to select CALIBRATE. ZERO & SPAN is selected by pressing the number 2 key. The ZERO
window is displayed first. It contains the chosen channel and the incoming signal on that channel. If the
signal displayed is within an acceptable range for zero, Press the ENTER key to accept this signal as
representing a display of zero while monitoring the transducer. If this signal is not appropriate, the user
may correct the problem while the window is displayed or press the ESC key and come back at a later
time to zero and span.
After setting the zero of the power supply, the SPAN menu window is displayed. If the displayed signal is
an acceptable full range value, press ENTER to accept it. The previously programmed display returns
with the selected channel now displaying the CAL’d value. If the incoming signal is not an acceptable full
range value, the operator try to correct any problems at this stage prior to pressing ENTER or, by pressing
the ESC key, they can exit SETUP/CAL and return to perform this procedure at a later date. See
Appendix D.
10.8.4. Setting a Multiplication Factor
For convenience, it is possible to leave a channel setup one way and merely multiply the display value by
some factor and replace the display with the new value. An example might be to set up a channel to read
from zero to one hundred percent and use a multiplication factor to make the display read from zero to
500 SCCM. An infinite number of possibilities are possible.
Once a channel in the CHANNEL SELECT portion of the SETUP/CAL menu has been selected, press
the number 7 key to select CALIBRATE. From the CALIBRATE menu, choose MULTIPLIER by
pressing the number 4 key. While the MULTIPLIER window is in the display, enter the multiplication
factor and press ENTER. The display returns to normal with the selected channel now displaying the
product of the normally displayed value and the entered factor.

10.9. SERIAL COMMUNICATION
Follow the instructions in the section, WIRING THE POWERPOD-400 for cabling and proper pin out for
serial communication with the unit. After insuring that the POWERPOD-400 is wired properly, the unit
must be set up following the instructions in the section entitled, External Communications Setup.
The instruction set for the POWERPOD-400 can be divided into two different types. They differ only in
that they
1. Write a command only or
2. Write a command and read a response.
Taking liberty with this vernacular, they may be differentiated using the terms COMMAND or QUERY.
The entire set of instructions can be found in Appendix B.
10.9.1. Commands
Typical RS-232 command structure is as follows: CMNDn<value>Cr
For example: To change channel three’s high alarm value to 75.00, send A3H075.00Cr.
RS-485 commands require only that an asterisk and the unit’s address precede the RS-232 Command.
Using the same example as above with a unit whose address is 10 (default), send *10A3H075.00Cr.
When the POWERPOD-400 is the terminating unit on a 485 bus, two jumpers, CJ1 and CJ2 can be
shorted to add the required terminating resistors. Remove two machine screws from the rear of the top
cover. Slide the cover off. The two jumpers are near the serial communication connectors.
10.9.2. Set Point Queries
Queries are used when information from the unit is required. Each query is followed by a response from
the POWERPOD-400.
In this case, the query is asking for a programmed value. Specifically, the set point of channel three, which
happens to be set at 50.00 of 100.00.
Sent
SP3Cr
Response
SP3 050.00
10.9.3. Alarm/Flag Queries
The state of the high and low flow alarms for each channel can be monitored via the DB-15 connecter (J8)
on the rear panel for immediate action from an alarm situation but the Totalizer set points can only be
monitored by reading a memory location’s Boolean setting via serial communication.
As shown in the section, Setting Limit Alarms, to simply QUERY channel three’s high alarm set point,
send A3HCr. Expect a response similar to A3H 075.00. The actual state of the alarm can be polled using
the STATUS query.
STCr
Which results in a response similar to
STATUS
OCA : CH1 AUTO CH2 CLOSED CH3 OPEN CH4 AUTO
HI/LO: 0/0 0/1 1/0 0/0
OCA is short for OPEN/CLOSED/AUTO.
HI/LO stands for the high flow limit alarm or the low flow limit alarm. One must parse the states if digital
tests are to be conducted.

To query the status of the totalizer flag on channel four (4), use the following command.
TF4Cr
The response will be either TF4 0 corresponding to a Boolean ‘FALSE’ indication that the totalizer flag
has not been set, or TF4 1, a Boolean ‘TRUE’, indicating that the total is equal to or beyond the totalizer
set point..
D41Cr command tells channel four (4) to display the TOTAL. It is not necessary that the front panel
read the total for the TOTALIZER to work. The Totalizer works in the background no matter what mode
the display is in.
NOTE: It must be emphasized that, if the total reaches the maximum of the
display (±999999), the unit effectively stops counting.

14.3 Spanning Unit.
The following instructions explain how to use the POWERPOD-400 command signal to supply a given
channel’s input with the proper span voltage and to set the display to read a transducer’s span value.
You must know four things prior to setting the display’s span value:
1. You must know the maximum signal level for the specific transducer connected to the
channel to be spanned (5 VDC, 10VDC or 20mA).
2. You must know the maximum value to be displayed when the maximum signal level for the
transducer is connected to the channel to be spanned.
3. You must insure that the channel’s multiplier is set to 1.0000.
4. You must know the channel’s ‘Span Value’. That is, the value that would NOW be
displayed (prior to any adjustment) if the maximum signal was fed into the input of the
channel to be adjusted.
1 and 2. If this information is not on the transducer itself, consult the manufacturer of the
transducer. Their literature or other documentation should specify the maximum output signal
from the transducer and the maximum value to be displayed at that signal level.
3. Setting the MULTIPLIER to 1.0000.
Press MODE
Press 3
Press ENTER
Press 1, 2, 3 or 4 depending on which channel is to be adjusted.
Press ENTER
Press 7
Press ENTER
Press 4
Press ENTER
Press 1.0000 using the numeric key pad.
Press ENTER
You have just set a channel’s multiplier to 1.0000.
4. If you do not know what the selected channel’s maximum display (Span) value is currently set
to, follow these steps.
Notice that the last step in this exercise is to press ESC, not ENTER.
Press MODE
Press 3
Press ENTER
Press 1, 2, 3 or 4 depending on which channel is to be adjusted.
Press ENTER
Press 7
Press ENTER
Press 3
Press ENTER
Read the VALUE from the display.

Congratulations!
You have just calibrated your PowerPod-400 to read zero at zero volts and the transducer’s max
display value at the transducer’s max signal input.
The only thing left to do is to insure that your transducer is calibrated and that it is wired correctly
to the PowerPod-400.
* Individual channels may be calibrated with calibrated transducers connected, breakout
connectors (not supplied) and precision multi-meters with NIST traceable calibrations (also not
supplied). Such procedures are not covered in this document.
! If the calibration for the channel just zeroed had been severely compromised prior to beginning
