VersiStart p III
12 Troubleshooting
12.1 Protection Responses
When a protection condition is detected, the VersiStart p III will write this to the
event log and may also trip or issue a warning. The soft starter's response depends
on the Protection Action setting (parameter group 6).
Some protection responses cannot be adjusted by the user. These trips are usually
caused by external events (such as phase loss) or by a fault within the soft starter.
These trips do not have associated parameters and cannot be set to Warn or Log.
If the VersiStart p III trips you will need to identify and clear the condition that
triggered the trip, then reset the soft starter before restarting. To reset the starter,
press the
RESET
button on the keypad or activate the Reset remote input.
If the VersiStart p III has issued a warning, the soft starter will reset itself once the
cause of the warning has been resolved.
12.2 Trip Messages
Display
Possible cause/Suggested solution
2 Phase -
Damaged SCR
This message is displayed if the soft starter tripped on “ Lx-Tx
shorted” during the pre-start checks and PowerThrough is
enabled. It indicates that the starter now operates in
PowerThough mode (2-phase control only).
Check for either a shorted SCR or a short within the bypass
contactor.
Related parameters: 6L
Battery/clock
A verification error has occurred on the real time clock, or the
backup battery voltage is low. If the battery is low and the power
is off, date/time settings will be lost. The VersiStart p III will
continue to soft start and soft stop correctly. Reprogram the date
and time.
The battery is not removable. In order to replace the battery, the
main control PCB must be replaced.
Related parameters: 6M
Bypass
overload
This trip is not adjustable.
Bypass overload protection protects the soft starter from severe
operating overloads while running. The soft starter will trip if it
detects overcurrent at 600% of the contactor rating.
