The alarm output 1 is connected to the connection terminals 7 and 8, the alarm output 2
with the connection terminals 9 and 10 and the alarm output 3 with the connection termi-
nals 12 and 13.

The switch behaviour of the A3 high/low alarm depends on the switch behaviour of
alarm A1 and A2 (if A1 and A2 are OFF at the same time, A3 is ON). Therefore use the
standby function, hysteresis and time delay of alarm A1 and A2 with the utmost caution.
■ If the alarms A1 and A2 are in the standby mode, alarm A3 is ON.
■ If the hysteresis of A1 or A2 is increased, than the span for A3 ON is
decreases.
■ If the delay time of A1 or A2 is changed, the time for A3 also changes.
■ If the delay time for A1 or A2 is set and the delay of A1 or A2 is active,
than A3 is ON.
