There are two alarm outputs in the controller. The signalling of any alarm
is carried out through the lighting of the red LED diode. Moreover, there
is information on the LCD display which alarm is active.

Fig.9. Kinds of alarms
The alarm configuration requires the selection of the alarm kind
through the
AL1-Type
and
AL2-Type
. Accessible types of alarms
are given on the fig.9.
The set point for absolute alarms is the value defined by the
AL1-SP
, and
AL2-SP
parameter and for relative alarms it is the
deviation from the set point in main circuit -
AL1-Dev
and
AL2-Dev
parameter
. The alarm hysteresis, i.e. the zone around the set
point, in which the output state is not changed, is defined by the
AL1-Hyst
and
AL2-Hyst parameter
