Target-cos(phi) changeover
Via the input target-cos(phi) changeover it can be
changed over between target-cos(phi1) and target-
cos(phi2).
If there is no voltage at the input, the target-cos(phi1)
is active. If there is a 85 bis 265V AC connected to the
input, the target-cos(phi2) is active.
In the standard display (please see example), apart from
the active channels and the actual cos(phi) also the ac-
tive target-cos(phi) is indicated.
Target-cos(phi1) is active.

Alarm output
The alarm relay attracts in undisturbed operation, and
the contact of the alarm output is closed. If a distur-
bance occurs, the alarm relay releases and the contact is
opened. Various events can be assigned to the alarm
output via OR-logic interconnections. Each event is as-
signed to an alarm number, an alarm delay and alarm
duration.
Check alarm output
If there is no alarm, the alarm relay attracts immedi-
ately. In order to trigger off an alarm, the threshold for
overtemperature can be set to zero, for instance, and
the alarm relay releases immediately.
