Introduction
This page intentionally left blank.
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.
Starter Selection
Select the RVS-DX soft starter according to the motor’s Full Load Amps. Also consider the

Installation
This page intentionally left blank.
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.
RVS-DX, Digital Soft Starter Instruction Manual—04/01/04
2-3
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.
120V control power must be connected at terminals A1 & A2.
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.
WA R N I N G
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.
WA R N I N G
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 RVSDX-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.
RVS-DX, Digital Soft Starter Instruction Manual—4/01/04
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.
RVS-DX, Digital Soft Starter Instruction Manual—4/01/04
5-4
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).
RVS-DX, Digital Soft Starter Instruction Manual—4/01/04
5-5
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:

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.
WA R N I N G
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.
RVS-DX, Digital Soft Starter Instruction Manual—4/01/04

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 SCR’s.
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.
RVS-DX, Digital Soft Starter Instruction Manual—4/01/04
5-7
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 recheck 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
Heatsink Over Temperature
The starter has thermal sensors mounted on the heatsink, tripping the starter when the heatsink
temperature rises above 85°C.
WA R N I N G
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.

Additional Protection Available:
Short Circuit Protection
Protects the starter against a short circuit by SCR protection fuses. A chart can be found in Appendix
C, page C-3.
Transient Protection
Line transient voltages can cause a malfunction of the starter and damage to the SCR’s. All RVS-DX
soft starters have MOV’s to protect from normal line voltage spikes.

Start-Up Procedure
This page intentionally left blank.
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 rampsup 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.
RVS-DX, Digital Soft Starter Instruction Manual—04/01/04
7-3
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.

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

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
(Optional) Initiates a signal when motor insulation level decreases below set level.
TRIP: INSULATION
(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
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.
LONG START TIME
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
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.
OVERLOAD
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
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.
UNDERVOLTAGE
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.
OVERVOLTAGE
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
Trips the starter when motor is not properly connected to load terminals.
SHORTER SCR
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 KΩ.
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
Heatsink overtemperature. Trips the starter when the heatsink temperature rises above
85°C. Improve cooling. Check the motor staring is not too frequent.
EXTERNAL FAULT
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.

Fault
Description
WRONG PARAMETERS
Parameters were not transferred from RAM to EEPROM. This may happen after
replacing the EEPROM with a new version program. Press “Reset” key, then “Mode”
and down arrow keys simultaneously and save new default parameters by pressing
“Store” and “Mode” keys simultaneously. (If “Fault” LED is illuminated, press
“Reset” key after storing parameters.)
NOTE: When operating in generator mode, shorted SCR and wrong connection faults are not active.
