List Of Warnings And Alarms - Danfoss VLT 6000 HVAC Series Quick Setup Manual

List of warnings and alarms

The table gi v es the different warnings and alarms
and indicates whether the fault locks the frequency
converter. After Trip locked, the mains supply must be
cut and the fault must be corrected. Reconnect the
mains supply and reset the frequency converter before
being ready. A Trip can be reset manually in three ways
1. Via the control key [RESET]
2. Via a digital input
3. Via serial communication In addition, an
automatic reset may be selected in parameter
400 Reset function.

Wherever a cross is placed under both Warning and
Alarm, this can mean that a warning precedes the
alarm. It can also mean that it is possible to program
whether a gi v en fault is to result in a warning or an
alarm. This is possible, e.g. in parameter 117 Motor
thermal protection. After a trip, the motor will be
coasting and on the frequency converter alarm and
warning will flash. If the fault is removed, only the
alarm will flash. After a reset, the frequency converter
will be ready to start operation again.
