TROUBLESHOOTING

The MVS provides extensive information to help the operator diagnose and remedy any operating difficulties.

In addition to the motor and load protection features already described, the MVS reports in detail on the starter's

own state. Any internal failure will cause the soft starter to trip, and full details will be recorded in the Trip Log and

Event Log.

13.1

Protection Responses

When a protection condition is detected, the MVS 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 16).

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 MVS 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 R

RESET button on the controller or activate the Reset remote

input.

If the MVS has issued a warning, the soft starter will reset itself once the cause of the warning has been resolved.

13.2

Trip Messages

This table lists soft starter's protection mechanisms and the probable cause of the trip. Some of these can be

adjusted using parameter group 4 Protection Settings and parameter group 16 Protection Action, other settings are
built-in system protections and cannot be set or adjusted.

Possible cause/Suggested solution

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 MVS 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: 16M

Bypass fail (bypass

contactor)

The bypass contactor has welded closed or is not operating correctly. There may be a

problem with the control circuit or the contactor coil.
Check the condition of the bypass contactor's main poles. Check the operation of the

contactor control circuitry and contactor coil.
This trip is not adjustable.

NOTE

You can use the Run Simulation to check the bypass contactor's operation

without mains voltage connected.

Controller

This is a name selected for a programmable input. Refer to Input A trip.

Current imbalance

Current imbalance can be caused by problems with the motor, the environment or the

installation, such as:



An imbalance in the incoming mains voltage



A problem with the motor windings



A light load on the motor



A phase loss on input terminals L1, L2 or L3 during Run mode

An SCR that has failed open circuit. A failed SCR can only be definitely diagnosed by replacing
the SCR and checking the starter's performance.
Related parameters: 4H, 4I, 16E

EEPROM fail



An error occurred loading data from the EEPROM to RAM when the controller powered
up.



"Load User Set" has been selected but no saved file is available.

Reset the fault and then reload the default settings. If the problem persists, contact your local
distributor.
Related parameters: None
