VersiStart i III
Display
Possible cause/Suggested solution
Motor Connection
Tx
Where 'X' is 1, 2 or 3.
The motor is not connected correctly to the soft starter.
x
Check individual motor connections to the soft starter for power circuit continuity.
x
Check connections at the motor terminal box.
This trip is not adjustable.
Related parameters: None
Motor thermistor
The motor thermistor input has been enabled and:
x
The resistance at the thermistor input has exceeded 3.6 k
ȍ
for more than one second.
x
The motor winding has overheated. Identify the cause of the overheating and allow the motor to
cool before restarting.
x
The motor thermistor input has been opened.
NOTE
If a valid motor thermistor is no longer used, a 1.2 k
ȍ
resistor must be fitted across
terminals 64, 65.
Related parameters: 16G
Network
communication
(between device
and network)
There is a network communication problem, or the network master may have sent a trip command to the
starter. Check the network for causes of communication inactivity.
Related parameters: 16L
No Flow
This is a name selected for a programmable input. Refer to Input A trip.
Parameter out of
range
x
A parameter value is outside the valid range.
The starter will load the default value for all affected parameters. Press
RESET
to go to the first
invalid parameter and adjust the setting.
Related parameters: None
Phase sequence
The phase sequence on the soft starter's input terminals (L1, L2, L3) is not valid.
Check the phase sequence on L1, L2, L3 and ensure the setting in parameter 4B is suitable for the
installation.
Related parameters: 4B
PLC
This is a name selected for a programmable input. Refer to Input A trip.
Power loss
The starter is not receiving mains supply on one or more phases when a Start Command is given.
Check that the main contactor closes when a start command is given, and remains closed until the end
of a soft stop. Check the fuses. If testing the soft starter with a small motor, it must draw at least 2% of
its minimum FLC setting on each phase.
Related parameters: None
Pump Fault
This is a name selected for a programmable input. Refer to Input A trip.
Starter
communication
(between device
and soft starter)
x
There is a problem with the connection between the soft starter and the optional communications
module. Remove and reinstall the module. If If the problem persists, contact your local
distributor.
x
There is an internal communications error within the soft starter. Contact your local distributor.
Related parameters: 16I
Starter Disable
This is a name selected for a programmable input. Refer to Input A trip.
Thermistor circuit
Check that a PT100 (RTD) is not connected to 64, 65.
The thermistor input has been enabled and:
x
The resistance at the input has fallen below 20
ȍ
(the cold resistance of most thermistors will be
over this value) or
x
A short circuit has occurred. Check and resolve this condition.
Related parameters: None
Time-overcurrent
The VersiStart i III is internally bypassed and has drawn high current during running. (The 10A
protection curve trip has been reached or the motor current has risen to 600% of the motor FLC setting.)
Related parameters: None
Undercurrent
The motor has experienced a sharp drop in current, caused by loss of load. Causes can include
broken components (shafts, belts or couplings), or a pump running dry.
Related parameters: 4C, 5C, 16C
Unsupported
option (function
not available in
inside delta)
The selected function is not available (eg jog is not supported in inside delta configuration).
Related parameters: None
Vibration
This is a name selected for a programmable input. Refer to Input A trip.
