■ List of warnings and alarms
The table gives the different warnings and alarms and
indicates whether the fault locks the VLT frequency
converter. After Trip locked, the mains supply must be
cut and the fault must be corrected. Reconnect the
mains supply and reset the VLT 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 given 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 VLT frequency converter alarm
and warning will flash. If the fault is removed, only the
alarm will flash. After a reset, the VLT frequency
converter will be ready to start operation again.
