Indication
• LCD: Does not display the type of the alarm (LCD active)

Cause for this Condition
If the affected alarm function is switched “OFF” before the alarm has disappeared or the
motor has been switched off, then the alarm stays on whether the motor is switched on or
off.
How to Get Rid of Alarm
• Go to SET VALUES mode.
• Switch on all alarm functions (e.g., “THERMAL WARNING” “ON”).
• As soon as the affected alarm function is switched on again, then the alarm condition
will disappear.
• Switch alarm function off if not required
Procedure if “TRIP” cannot be Reset
There are two reasons why a trip can not be reset if the motor is not running.
