Possible cause/Suggested solution
No Flow
This is a name selected for a programmable input. See Input A trip.
Parameter out of
range
•
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. See 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. See Input A trip.
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.
Related parameters: 16I
Starter Disable
This is a name selected for a programmable input. See Input A trip.
Thermistor circuit
Check that a PT100 (RTD) is not connected to 64, 65.
The thermistor input has been enabled and:
•
The resistance at the input has fallen below 20
Ω
(the cold resistance of
most thermistors will be over this value) or
•
A short circuit has occurred. Check and resolve this condition.
Related parameters: None
Time-overcurrent
The ASTAT XL 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 Alarm
This is a name selected for a programmable input. See Input A trip.
VZC Fail Px
Where 'X' is 1, 2 or 3.
Internal fault (PCB fault). Contact your local supplier for advice.
This trip is not adjustable.
Related parameters: None
