Overview  
The RVS-DX is a digital electronic soft starter, incorporating six SCR’s to start a three phase squirrel  
cage induction motor by supplying a slowly increasing voltage, providing soft start and smooth  
stepless acceleration, while drawing the minimum current necessary to start the motor. The RVS-DX  
is equipped with internal bypass relays initiated by its microprocessor control (on units 31-310  
amps).  
Using the soft stop, the RVS-DX slowly reduces the motor voltage, thus softly stopping a high  
friction load. In applications where the inertia of a load would cause the motor to “free wheel”; the  
soft stop will not stop the motor any faster than the coast to stop.

Physical Installation  
Location of the RVS-DX is important to achieve proper performance and normal operating life. The  
unit should be installed in an area where it will be protected from:  
Direct sunlight, rain or moisture  
Corrosive gases or liquids  
Vibration, airborne dust or metallic particles  
When preparing to mount the RVS-DX, lift it by its base, never by the front cover. For effective  
cooling as well as proper maintenance, the RVS-DX must be installed on a flat, non-flammable  
vertical surface (wall or panel) using four mounting screws. There must be a minimum of 4.7 inches  
of clearance above and below the RVS-DX for sufficient airflow. A minimum of 1.2 inches of  
clearance is required on each side of the RVS-DX.  
The protected chassis is rated to operate over a temperature range of -14°F (-10°C) to +122°F  
(40°C). Relative non-condensing humidity should not exceed 93%.  
Enclosures  
If the RVS-DX is to be mounted in a customer supplied enclosure, the heat dissipation should be  
considered when sizing an enclosure. Maximum surrounding air temperature should not exceed  
40°C. Since the RVS-DX does have built in bypass after acceleration, the watts loss is minimized.  
The RVS-DX watts loss is approximately 0.4 x the FLA in watts. (example: for a motor of 100A,  
expect watts loss of the starter to be 40 watts.) Internal enclosure heating can be reduced by using  
additional ventilation.

Built in Bypass After Acceleration  
The bypass after acceleration allows the RVS-DX to control the motor during starting and stopping  
for smooth, step-less acceleration and deceleration. However, once up to full voltage the RVS-DX is  
bypassed to reduce the watt loss.  
The RVS-DX incorporates internal bypass relays allowing current flow through the SCR’s only  
during the soft start process. At the end of the soft start, the built-in relays bypass the SCR’s and  
carry current to the motor. Upon stop signal, or in case of fault, all three bypass relays will open and  
stop the motor. When the decel time is set to allow soft stopping, upon stop command, the bypass  
relays will open immediately and the current will flow through the SCR’s. The voltage will then be  
reduced slowly and smoothly to zero.  
RVS-DX units rated 31-310 amps have built-in bypass.

Fault Contact  
(Note 4)  
N.O. contact closes upon any fault and returns to open position (after the fault  
has been removed) upon reset, or disconnection of main supply voltage.  
1. The control power should be connected to A2, and control neutral to A1.  
2. The auxiliary input can be programmed to operate as a reset, dual adjustment, generator starting, slow speed, slow  
speed reverse, or external fault (see chapter 6 on parameters to set the auxiliary input).  
3.If the auxiliary output is set to Immediate, the contact closes at the start signal, and opens at the stop signal, end of soft  
stop fault, or at loss of voltage. If the auxiliary output is set to End of Acceleration, the contact closes after acceleration  
and opens at stop or soft stop signals, fault, or loss of voltage.  
4. If the fault contact is set to fail-safe, the contact closes immediately when control power is connected, and opens upon  
fault.  
WARNING  
Do not use the fault contact to trip an upstream contactor. When the fault contact trips the  
upstream contactor, main voltage will be disconnected thus resetting the soft starter and the  
motor will restart immediately upon power being restored.  
WARNING  
Start/stop with maintained contact. When the line contractor is operated by a maintained contact,  
if main supply voltage is lost, the motor will automatically restart upon voltage restoration. When  
resetting after a fault, the motor will restart upon the fault being reset.

Operating “Inside the Delta”  
Using the RVS-DX soft starter “inside the delta” reduces the required soft starter rating by 1.73 ( 3)  
factor. For example, for a 150 amp, 460 volt motor, the RVS-DX-170-D is selected to operate in  
standard “line” mode. However, for “inside the delta” mode (150 amp÷1.73=87 amps), the RVS-  
DX-105-D can be selected, thereby, reducing cost and physical space in the application.  
The following programming parameters are disabled, once the ‘inside the delta’ is selected:

Start/Stop Features  
The RVS-DX incorporates many features that assist in starting and/or stopping various applications.  
These features are described within this section.  
Pump Control (Start Curves)  
Induction motors produce peak torque up to three times the rated torque. This peak torque can occur  
towards the end of the starting process. In pump applications, this peak torque may cause high  
pressure in the pipes.  
The RVS-DX incorporates four different starting curves. The start curve (curve 0) is the standard  
curve and the default. It is the most stable and suitable curve for the motor, preventing prolonged  
starting and motor overheating. Pump start curves (1, 2, and 3) automatically control the voltage  
ramp-up to reduce peak torque. The multiple starting curves are shown below:  
Voltage  
Torque  
Speed  
DOL  
0
1
2
3
Time  
NOTE: Always start with Start curve 0. If towards end of acceleration, peak torque is too high,  
proceed to curve 1, then 2 and 3 if necessary.  
Tach Feedback (0-10 VDC)  
The tach feedback provides linear acceleration and deceleration curves according to RPM feedback.  
Twelve tachometer gain levels can be selected for closed loop control for starting and stopping.  
NOTE: Always begin with minimum gain (0) and proceed with higher gain levels if required.  
Pulse Start  
The pulse start feature is used to break away high friction loads. High friction loads may require  
close to across the line starting torque for a very short duration of time. The pulse start feature  
accomplishes this with an 80% voltage boost (without current limit) for a period of 0.1 to 1 second.  
After this pulse, the voltage is ramped down to the initial voltage setting where it begins ramping up  
again to full voltage.

5-3

Initial Voltage  
The initial voltage determines the motor’s initial torque setting (the torque is directly proportional to  
the square of the voltage). The initial voltage can be set from 10 to 50%. The initial voltage also  
affects the inrush current and mechanical shock. An initial voltage setting that is too high may cause  
mechanical shock and a high inrush current. An initial voltage setting that is too low may result in a  
prolonged period of time before the motor begins to turn.  
Generally, this setting should cause the motor to begin turning immediately after the start signal,  
while minimizing mechanical shock and inrush current.  
Current Limit  
The current limit feature sets the highest current level that will reach the motor during the starting  
process. The current limit may be set from 100 to 400%. Once the present current limit value is  
reached the voltage will level off and only continue ramping up once the current is below the limit  
again.  
If the current limit is set too high, there will be a greater current draw from the main power and a  
faster acceleration. If the current limit is set too low, the motor may be unable to reach full speed (the  
starter may trip on maximum start time).  
Generally the setting should be high enough to start the motor without stalling.  
Acceleration Time  
The acceleration time determines the motor’s voltage ramp up time from initial to full voltage. The  
acceleration time can be set from 1 to 30 seconds.  
The time it takes the motor to reach full speed may not necessarily be the same as the acceleration  
time. The following situations may override the acceleration time setting.  
1. Since current limit overrides acceleration time, setting the current limit low will extend the  
acceleration time (but never to exceed maximum start time).  
2. When the motor reaches full speed prior to reaching nominal voltage, acceleration time is  
overridden and voltage quickly ramps up to nominal. (This situation is common with lightly  
loaded motors.)  
3. Using curves (1, 2, or 3) will prevent a quick acceleration time.  
Generally this setting should be the minimum acceptable time.  
Maximum Start Time  
The maximum start time is the maximum allowable time from start signal to end of acceleration. If  
the voltage does not reach nominal during this time period, the RVS-DX will trip, and the LCD  
display will read “LONG START TIME”. The maximum start time is settable from 1 to 30 seconds.

Stop Curves  
For many applications, the load torque decreases in a square relation to the speed. In these  
applications, reducing the voltage will reduce the torque and the motor will smoothly decelerate to a  
stop. With these applications the standard stop curve (0) will be adequate. The stop curve (0) reduces  
the voltage linearly from nominal to zero.  
In some other applications (namely pumps), a considerable amount of the torque is constant and does  
not decrease with speed. In these applications the motor torque could fall below load torque during  
stopping, causing the motor to stall. By using stop curves (1, 2 or 3) the motor will smoothly  
decrease to zero speed and prevent the stall condition.  
The stop curves are shown in the graph below:  
Voltage  
Deceleration  
0
1
2
3
NOTE: Always begin with Stop Curve 0. If your motor stalls quickly, instead of slowly decreasing  
its speed then try selecting stop curve 1, then 2 and then 3 if necessary.  
Deceleration Time (Soft Stop)  
The deceleration time is used for controlled deceleration of high friction loads. When the soft stop is  
initiated the RVS-DX’s output voltage is gradually ramped down. The deceleration time is  
programmable from 0 to 30 seconds.  
Final Torque  
The final torque setting determines the torque towards the end of the soft stop. If the motor stalls  
while current is still flowing and the speed has softly been reduced to zero, increase the final torque  
setting to prevent unnecessary motor heating. The final torque can be set from 0 to 10 (maximum).

Dual Adjustment  
The dual adjustment feature allows the RVS-DX to have two sets of starting characteristics. This  
feature is very beneficial in applications where the motor may be starting loaded or unloaded. There  
is also a dual setting for motor FLA, which allows the RVS-DX to operate a two speed motor with  
adequate motor protection.  
The RVS-DX is transferred to the dual adjustment settings by connection of control power to  
terminal C1, when it is programmed to Dual Adjust. The dual adjustment parameters are:

8-390 Amps depending upon RVS-DX’s FLC.  
Slow Speed Torque  
The slow speed torque determines the torque while the motor is operating at 1/6 of the nominal  
speed. The slow speed torque can be set from 1 to 10.  
Maximum Slow Speed Time  
The maximum slow speed time sets the allowable operation time that the RVS-DX can run at slow  
speed. The setting range is from 1 to 30 seconds.  
WARNING  
Operating current while motor is running at 1/6 speed is much higher than nominal current  
and motor ventilation is much weaker. Special precaution should be taken to prevent  
overheating while running at slow speed for long periods of time.

Motor Protection Features  
The RVS-DX incorporates advanced microprocessor-based digital circuitry, which allows for  
sophisticated motor protection with digital accuracy. The motor protection features are covered in  
detail below.  
Too Many Starts  
The “too many starts” feature allows programming of the maximum allowable starts during the  
“starting period”. The maximum amount of starts may be set from 1 to 10 starts within a 1 to 60  
minute starting period.  
Start Inhibit  
The start inhibit sets the time period which starting is disabled after a “TOO MANY STARTS” trip.  
The setting range is from 1 to 60 minutes.  
NOTE: When trying to start the motor before the “Start Inhibit” time has elapsed, the LCD will  
display “WAIT BEFORE RESTART: xx MIN.”.  
Maximum Start Time (Stall Protection)  
The maximum start time will trip the starter if the motor does not reach full speed during the  
“Maximum Start Time”. The maximum start time is settable from 1 to 30 seconds.  
Electronic Fuse (Shear-pin)  
The electronic fuse is used to protect the starter and motor from high current. The electronic fuse has  
two operating modes: one for during start, and one for during operation.  
During starting: the starter trips when the current exceeds 850% of the motor FLA setting in 1  
cycle or less.  
During operation: (After acceleration period; “Run” LED will be on.) The starter trips when  
current exceeds the set current level of 200 to 850% in the programmed delay time.  
NOTE: The electronic fuse is not intended to replace fast acting fuses to protect SCRs.  
Electronic Overload  
The electronic overload becomes operational when the “RUN” LED is lit. The starter incorporates a  
thermal memory register which calculates heating minus dissipation of the motor. When the thermal  
memory fills up, the starter trips. The thermal register resets itself 15 minutes after the motor stops.  
The electronic overload is settable from 75 to 150% of motor’s FLA. (Factory setting is 115%). The  
tripping time at 5xFLA is adjustable from 1 to 10 seconds, thus allowing a trip curve selection.  
Undercurrent  
The undercurrent is operational when the motor is running. The starter trips when motor current  
drops below the set undercurrent trip level for a time period longer than the undercurrent delay time.  
The undercurrent setting ranges from (0=off) 20 to 90% of FLA, and the undercurrent delay ranges  
from 1 to 40 seconds.

5-7  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Undervoltage  
The under voltage function becomes available only after the start signal. The starter will trip when  
the main voltage drops below the preset level for a time period longer than the under voltage delay.  
The under voltage trip setting ranges from 50-90%. The under voltage delay can be adjusted from 1  
to 10 seconds. The under voltage fault can be auto reset. The auto reset must be enabled (see “Fault  
Parameters” in Chapter 6). The starter will re-check for the under voltage fault after 60 seconds and  
will auto reset as long as the run signal has been removed and the fault condition has cleared.  
Overvoltage  
The overvoltage function becomes operational only after the start signal. The starter will trip when  
the main voltage rises above the preset level for a time period longer than the overvoltage delay. The  
overvoltage trip setting ranges from 110-150%. The overvoltage delay can be adjusted from 1 to 10  
seconds.  
Phase Loss (and under/over frequency)  
This protection feature is operational when the starter is energized. It is designed to protect the motor  
from single phasing. The starter will trip when 1 or 2 phases are missing for more than one second.  
The starter will also trip when frequency is less than 45 Hz or greater than 65 Hz. The phase loss  
fault can be auto reset. The auto reset must be enabled (see Fault Parameters). The starter will re-  
check for the phase loss fault after 60 seconds, and will auto reset as long as the run signal has been  
removed and the fault condition has cleared.  
Phase Sequence  
The phase sequence function becomes operational as soon as the starter is energized. The phase  
sequence protection must be enabled (see “Fault Parameters” in Chapter 6). The starter will trip  
when the phase sequencing is wrong.  
Low Slow Speed Time  
This function will trip the starter if the motor operates at slow speed (forward or reverse direction)  
longer than the Maximum Slow Speed Time (settable from 1 to 30 seconds). When the motor  
operates at slow speed it draws higher than nominal current (depending upon the slow speed torque  
setting), thus the motor and starter may overheat.  
NOTE: Always operate the motor at slow speed for the minimum possible time to prevent  
overheating.  
Wrong Connection  
The wrong connection protection indicates when the motor is not connected to the load terminals, or  
there is an internal disconnection in the motor winding.  
Shorted SCR Protection  
The shorted SCR protection trips the starter when one or more SCRs have been shorted.  
NOTE: The soft starter will also trip on the “SHORTED SCR” if the main voltage is applied to the  
load terminals.  
RVS-DX, Digital Soft Starter Instruction Manual—4/01/04  
5-8  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Heatsink Over Temperature  
The starter has thermal sensors mounted on the heatsink, tripping the starter when the heatsink  
temperature rises above 85°C.  
WARNING  
The over temperature protection is designed to operate under normal conditions. The SCRs  
could overheat and fail before the heatsink reaches 85°C in the following situations: if the  
starter is run at extended low overload, with insufficient ventilation, sized improperly, started  
too frequently, or started frequently beyond maximum conditions.  
Wrong Parameters  
This protection indicates when incorrect parameters have been entered into the EEPROM. This can  
also occur when parameters have been incorrectly transferred from RAM to EEPROM.  
External Fault  
The external fault becomes operational when the starter is energized. The starter will trip when the  
external (N.O.) contact on terminal C1 closes for more than 2 seconds. (Aux. input C1 must be  
programmed to External Fault).  
Fault and Reset  
When any of the above protections cause the starter to trip, it locks in a fault condition and disables  
the SCR firing. The “Fault” LED illuminates, the LCD displays the fault message, and the fault  
contact (at terminals 23 & 24) closes.  
The fault may be reset:  
–via the “Reset” key on the keypad.  
–via input at terminal C1.  
NOTE: The fault may only be reset once the fault condition has cleared and the run signal is  
removed.  
NOTE: If fault occurs due to voltage outage, fault condition is latched and reappears upon  
voltage restoration.  
Fault and Auto Reset  
The phase loss and under voltage trips can be auto reset. The auto reset must be enabled. This is  
accomplished in the “Fault Parameters” mode. When auto reset is enabled, the faults due to phase  
loss and under voltage will receive a reset signal after a delay of 60 seconds. If the fault condition  
has cleared and the start signal has been removed, then the fault will be reset.

(1) The FLC of the RVS-DX is pre-determined by the size of the power section. This setting can be adjusted  
lower, but not higher than the unit’s rating. The Motor FLA setting is shown in amps. The default value will  
be matched to the FLC of the RVS-DX value, and can be modified from 50-100% of the FLC value.  
(2) Access to these parameters is available when dip switch 1.2 is ON.  
(3) The setting in parenthesis is the maximum setting of that parameter when the WIDER PARAMETERS is set  
to enable.

Start-Up Procedure  
NOTE: If the motor is NOT connected to the load terminals, the “WRONG CONNECTION” fault  
indication will appear on LCD display.  
Start-Up Procedure:  
1. Connect an N.O. maintained push button from terminals B1 to A2.  
2. Connect control power to terminals A1 and A2. (ON LED should illuminate.)  
3. Reveiw all parameters with “Mode” and “Select” keys and set parameters as required.  
4. If necessary, return to Default Parameters (see page 6-5, “Service” Mode).  
5. Connect main voltage to starter’s line terminals (L1, L2, and L3), and motor to load terminals  
(U, V, and W).  
6. Set LCD to show “% OF MOTOR FLA”.  
7. Press the “Start” button. If motor starts to turn shortly after the start signal proceed to Step 8. If  
the motor does not begin turning, increase the “Initial Voltage” and press “Start” again. When  
starting if initial inrush and mechanical shock are too high, decrease “Initial Voltage” setting,  
and proceed to Step 8.  
8. Motor has begun to turn. If speed accelerates to nominal proceed to Step 9. If the motor speed  
does not accelerate to nominal, increase the “Current Limit” setting. If the current during  
acceleration process is too high, decrease the “Current Limit” setting, and proceed to Step 9.  
9. Press the “Soft Stop” button and wait for the motor to stop.  
10. Slightly increase the “Initial Voltage” and “Current Limit” settings to allow for load changes.  
11. Press “Start” button and see that the motor “Acceleration Time” to full speed is as required.  
12. If acceleration time is too short, increase “Acceleration Time” setting as required.  
13. Check the total starting time and set “Max. Start Time” to approximately 5 seconds longer than  
the maximum time required to start the motor.  
14. Repeat the same for the soft stop process.  
NOTE: When power factor correction capacitors are used, they must be installed on the soft  
starter line side.  
Examples of starting curves  
Light Loads-Pumps, Fans, etc.  
Initial Voltage (IV)-set to 30% (Factory Default)  
Current Limit (CL)-set 300%  
Acceleration Time (AT)-set 5 sec.  
Voltage quickly increases to the Initial  
Voltage value and then gradually ramps-  
up to nominal. Current simultaneously  
and smoothly increases to reach Current  
Limit setting or less, before smoothly  
decreasing to the operating current.  
Motor speed will accelerate to full speed  
quickly and smoothly.

High Inertia Loads-Fans, Centrifuges, etc.  
Initial Voltage (IV)-set 50%  
Current limit (CL)-set 400%  
Acceleration time (AT)-set 20 sec.  
Voltage and current increase until  
current reaches “ Current Limit”. The  
volatage is held at this value until  
motor is close to nominal speed, then  
current will begin to decrease. The  
HRVS-DX continues to ramp-up the  
voltage until reaching nominal. Motor speed smoothly accelerates to full speed.  
Special starting-Using Dual Adjustment  
Using two starting characteristics, the starter will accelerate to the  
Dual Adjustment-IV reaching 100% current limit. After the  
Immediate Relay delay time, voltage to terminal C1 is switched  
off, using the standard characteristic to complete acceleration.  
This method of starting is useful to prevent initial high  
acceleration.

frequency, etc.)

Start Up Procedure With Pump Control  
Starting Curve  
1. Adjust main parameters as necessary (FLA, FLC, etc).  
2. Set Starting Curve, Acceleration Time, Current Limit, and Initial Voltage to their default values  
(curve 0, 10 sec., 400% and 30% respectively).  
3. Start the pump while watching the pressure gauge as the pump starts and look for overshooting  
(“Pressure Surge”) of the gauge needle  
above the target pressure. In case of over  
pressure, choose a peak torque reduction  
Pump control during  
curve (Pump Control curve 1!).  
Voltage  
4. Set Start Curve 1!, increase Acceleration  
Time to 15 sec. and reduce Current Limit  
to 350%. Start the pump and watch the  
pressure gauge while the pump starts.  
5. In most cases, overshooting is reduced, if  
the overshoot persists, increase Acceleration time to 25 sec. (confirm with motor manufacturer)  
and try again.  
6. If the overpressure persists, increase Starting Curve setting to 2!, or 3!, if necessary. Each  
increase in Starting Curve setting will reduce the Peak Torque, thus, reducing the overpressure  
and preventing the “Pressure Surge” during start.  
7. To increase starting time above these maximums, employ “Extended Parameters Settings” (page  
5-7).  
Stopping Curve  
1. Adjust main parameters as necessary (FLA, FLC, etc.)  
2. Set Stop Curve and Deceleration Time, to their default values (curve 0, 10 sec., respectively).  
3. Stop the pump, watching the pressure gauge and check valve as the pump stops. Look for  
overshooting (“Water Hammer”) of the gauge  
(abruptly stops the pump and the motor).  
4. Select Stop Curve 1, increase Deceleration time  
to 15 seconds. Stop the pump and watch the  
pressure gauge and the rate of closing of the  
check valve as the pump stops. Abrupt stopping  
of the pump and motor will cause a loud audible  
noise emitted from the check valve.  
5. In most cases, “Water Hammer” is reduced. If the  
“Water Hammer” persists, increase the time to 25  
seconds (confirm with motor manufacturer) and try again.  
6. If the “Water Hammer” persists, increase Stop Curve setting to 2!, or 3!. Each increase in stop  
curve will reduce the abrupt stop of the pump, thus, preventing the “Water Hammer”  
phenomenon.

Final torque during soft-stopping a pump motor  
1. While decelerating, the check valve may close  
before Deceleration Time has elapsed, thus,  
allowing current to flow through stator winding  
causing unnecessary heat. Select Final Torque  
sensitivity to 1, and stop the pump, confirm that  
current stopped flowing through the motor  
shortly after the check valve closed.  
2. If current still flows more than 3-5 seconds  
after check valve closure, increase Final Torque  
up to 10 if necessary, to stop current flow earlier.

Troubleshooting  
Upon fault the motor stops, “Fault” LED illuminates and fault relay operates. The LCD will display  
“Trip: fault description”.  
Check “Statistical Data” for additional fault-related information.  
Fault  
Description  
ALARM: INSULATION  
TRIP: INSULATION  
(Optional) Initiates a signal when motor insulation level decreases below set level.  
(Optional) Trips the starter when motor insulation level decreases below trip value.  
Check motor and cable insulation level.  
TRIP: THERMISTOR  
(Optional) Trips the starter when motor’s thermistor resistance decreases below trip  
value. Check thermistor and cable’s resistance; check motor temperature near  
thermistor location.  
TOO MANY STARTS  
LONG START TIME  
Trips the starter if the number of starts during “Start Period” exceeds the preset  
number. Wait until motor and starter cool down–according to “Start Inhibit” setting.  
Trips the starter if output voltage does not reach nominal at the preset time. Check  
“FLA”, “FLC” and “Max. Start Time” settings. Increase “Initial Voltage”, “Current  
Limit” and “Max. Start Time” settings or decrease “Acceleration Time” as necessary.  
O/C–SHEAR PIN  
OVERLOAD  
The electronic fuse trips the starter instantaneously when current exceeds 8.5 X FLA  
during starting or 200-850% during running. Check “FLA”, “FLC” settings, motor  
and cable connections. Check that the motor is not stalled.  
Trips the starter when current exceeds the Overload Trip level and thermal register has  
filled up. Check “FLA”, “FLC” and “Overload” settings, and check the motor current.  
Wait 15 minutes to let the motor and stater cool down before starting.  
UNDERCURRENT  
UNDERVOLTAGE  
OVERVOLTAGE  
Trips the starter when line current drops below the preset level for the preset time.  
Check “Undercurrent Trip” and “Undercurrent Delay” settings. Check line current  
through L1, L2, and L3.  
Trips the starter when line voltage drops below the preset level for the preset time.  
Check “Undervoltage Trip” and “Undervoltage Delay” settings. Check line voltage  
through L1, L2 and L3.  
Trips the starter when line voltage rises above the preset level for the preset time.  
Check “Overload Trip” and “Overvoltage Delay” settings. Check line voltage through  
L1, L2 and L3.  
PHASE LOSS  
Trips the starter if 1 or 2 phases are missing. Check line voltages through L1, L2 and  
L3. Check that the frequency variations are between 45 to 65 Hz.  
PHASE SEQUENCE  
Trips the starter if input phase sequence is wrong. Check line phase sequence and if  
wrong, swap two wires on the line side. If the motor rotates in the wrong direction,  
swap two wires on the load side.  
MAX. SLOW SP TIME  
Trips the starter when operating at slow speed for extended period of time. Check that  
operation time at Slow Speed is shorter than the “Max. Slow Speed Time” setting.  
NOTE: Motor and starter may overheat when operating at slow speed for an extended  
period of time.  
WRONG CONNECTION  
SHORTER SCR  
Trips the starter when motor is not properly connected to load terminals.  
Trips the starter and prevents starting if one or more SCRs are short circuited or when  
motor windings are shorted. Check with an ohmmeter between L1-U, L2-V and L3-W,  
resistance > 20 K.  
SCRs may fail due to:  
High short current not protected by proper fuses.  
High voltage spikes not protected by proper external varistors.  
Frequent starting at max. conditions or fault conditions.  
OVERTEMPERATURE  
EXTERNAL FAULT  
Heatsink overtemperature. Trips the starter when the heatsink temperature rises above  
85°C. Improve cooling. Check the motor staring is not too frequent.  
Trips the starter when a N.O. contact between terminal A2 and C1 closes for over two  
seconds. Check contact position and cause of closure.
