to 0.1 % of the I

Up to three alarm outputs can be set (see parameter 26). Then
serial numbers 1
÷
3 are assigned to the outputs by order of standard outputs numbering, so
the alarm outputs are marked AR1
÷
AR3. If at least one of outputs is set as such alarm
output you can set in the subparameter No. 5 which of the outputs should signal
appropriate alarm event. In the subparameter there are three characters corresponding to
the alarm ouputs (relays) AR1
÷
AR3. The characters mean :
◦
-
= corresponding alarm output does not exist (is not set)
◦
O
= corresponding alarm output not affected by appropriate alarm event
◦

3
= corresponding alarm output AR1/AR2/AR3
is affected
by appropriate
alarm event
Thus in the example above, alarm No. 04 is indicated by alarm output AR2. Alarm output
AR1 is not affected by this alarm event and alarm output AR3 does not exist.

Alarm indication can be set or switched off. For most of the alarms you can set the actuation too.
Alarm actuation usually causes disconnection (step-by-step ) of all of affected compensation sections,
including the fixed ones. Due to this the controller gets into standby state. Exceptions of this rule are
listed in individual alarm overview below.
Permanently lit or hidden alarm activity symbol
indicates alarm condition being just active.
