24-09 Emergency Mode Alarm Handling
Option:
Function:
[0]
Trip+Reset,
Critical
Alarms
If this mode is selected, the frequency
converter continues 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
If there is a critical alarm, the frequency
converter trips and does not auto restart
(manual reset).
[2]
Trip, All
Alarms/Test
It is possible to test the operation of
emergency mode, but all alarm states are
activated normally (manual reset).
NOTICE
Certain alarms are warranty-affecting alarms that can
affect the lifetime of the frequency converter. Should 1
of these ignored alarms occur while in emergency mode,
a log of the event is stored in the emergency mode log.
Here the 10 latest events of warranty-affecting alarms,
emergency mode activation, and emergency mode
deactivation are stored.
NOTICE
The setting in
parameter 14-20 Reset Mode
is disregarded
if emergency mode is active (see parameter group
24-0*
Emergency Mode
).
