24-09 Fire Mode Alarm Handling
Option: Function:
[0] Trip+Reset, Critical Alarms If this mode is selected, the frequency converter will continue to run, ignoring most alarms, EVEN
IF DOING SO MAY RESULT IN DAMAGE OF THE FREQUENCY CONVERTER. Critical alarms are
alarms, which cannot be suppressed but a restart attempt is possible (Infinity Automatic Reset).
[1] * Trip, Critical Alarms In case of a critical alarm, the frequency converter will trip and not auto-restart (Manual Reset).
[2] Trip, All Alarms/Test It is possible to test the operation of Fire Mode, but all alarm states are activated normally (Manual
Reset).
NB!
Warranty-affecting alarms. Certain alarms can affect
the lifetime of the frequency converter. Should one of
these ignored alarms occur whilst in Fire Mode, a log
of the event is stored in the Fire Mode Log.
Here the 10 latest events of warranty-affecting alarms,
fire mode activation and fire mode deactivation are
stored.
NB!
The setting in par. 14-20
Reset Mode
is disregarded in
case of Fire Mode being active (see par. 24-0*, Fire
Mode).
