Function:
Select an option to define the
response to alarms when fire mode
is active and an alarm is issued.
Trip+Reset, Alarms are ignored even though
Critical Alarms damage maybe caused, except for
the critical alarms mentioned in
Table 3.30. When these alarms
occur, the frequency converter trips
immediately, followed by an
automatic reset and restarts even if
the operation leads to an infinite
loop of trip and restart.
Trip, Critical Alarms are ignored even though
Alarms damage maybe caused, except for
the critical alarms mentioned in
Table 3.30. For the critical alarms, a
trip is caused. A manual reset is
required before restart. A manual
restart requires disabling fire mode
and enabling fire mode again.
Trip, All Option for testing fire mode
Alarms/Test operation without compromising
the normal handling of warnings
and alarms. All alarms are handled
as normally and defined in Table
4.1 Alarm/Warning Code List.
