Possible cause/Suggested solution
Motor 2 overload
See 'Motor Overload' above.
NOTE
Applicable only if the second motor set has been programmed.

Motor connection Tx
Where 'X' is 1, 2 or 3.
The motor is not connected correctly to the soft starter for in-line or inside delta use.
Check individual motor connections to the soft starter for power circuit continuity.
Check connections at the motor terminal box.
This trip is not adjustable.
Related Pr: None
Motor thermistor
The motor thermistor input has been enabled and:
The resistance at the thermistor input has exceeded 3.6 k
Ω
for more than one second.
The motor winding has overheated. Identify the cause of the overheating and allow the motor to
cool before restarting.
The motor thermistor input has been opened.
NOTE
If a valid motor thermistor is no longer used, a 1.2 k
Ω
resistor must be fitted across terminals
TH1, TH2.

Network communication
(between module and
network)
The network master has sent a trip command to the starter, or there may be a network communication
problem.
Check the network for causes of communication inactivity.

Overpower
The motor has experienced a sharp rise in power. Causes can include a momentary overload
condition which has exceeded the adjustable delay time.

Parameter out of Range
This trip is not adjustable.
A parameter value is outside the valid range.
The keypad will indicate the first invalid parameter.
An error occurred loading data from the EEPROM to RAM when the keypad powered up.
The parameter set or values in the keypad do not match the parameters in the starter.
"Load User Set" has been selected but no saved file is available.
Reset the fault. The starter will load the default settings. If the problem persists, contact your local
distributor.
Related Pr: 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 Pr
5D
is suitable for the installation.

Power loss/Power circuit
This trip is not adjustable.
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 Pr: None
Power On in Simulation
mode
The soft starter will not activate Run Simulation with three-phase power connected. This prevents
unintentional direct on-line (DOL) start.
RTD/PT100 A
RTD/PT100 B to G
The RTD/PT100 set temperature has been exceeded and tripped the soft starter. Identify and resolve
the condition which caused the appropriate input to activate.
NOTE
PT100 B to PT100 G are applicable only if a RTD/PT100 and Ground Fault card is fitted.

RTD/PT100 X Circt
Indicates that the indicated RTD/PT100 has short circuited. Check and resolve this condition.
Related Pr: None.
Starter communication
(between module and soft
starter)
There is a problem with the connection between the soft starter and the optional communications
module. Remove and reinstall the module. If the problem persists, contact your local distributor.
There is an internal communications error within the soft starter. Contact your local distributor.
