VersiStart p III
Display
Possible cause/Suggested solution
RTD Circuit
The smart card has detected a fault with the RTD sensor, or the
RTD has activated temperature protection.
Related parameters: 6W, 17B
SCR Itsm
The SCR current surge rating has been exceeded.
Related parameters: None
SCR
overtemperatur
e
The temperature of the SCRs, calculated by the thermal model, is
too high to allow further operation. Wait for the starter to cool.
Related parameters: None
Starter
communication
There is a problem with the connection between the soft starter
and the optional expansion card. Remove and reinstall the card.
If the problem persists, contact your local distributor.
Related parameters: 6G
Thermistor
circuit
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 VersiStart p 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: 5C, 5D, 6B
Unsupported
option
The selected function is not available (eg jog is not supported in
inside delta configuration).
Related parameters: None
VZC Fail Px
Where 'X' is 1, 2 or 3.
Internal fault (PCB fault). Contact your local supplier for advice.
Related parameters: None
Zero Speed
Detect
The zero speed input has not closed within the expected duration
of a soft stop.
•
Check the zero speed sensor is operating correctly.
•
Check that parameters 2Q
Brake Current Limit
and 5G
Excess Start Time
are appropriate for the application.
Related parameters: 2Q, 3Q, 5G
