NON FAILSAFE:
The relay picks up when the alarm is triggered.
The relay drops out when the alarm is triggered.
FAILSAFE:
An alarm is also triggered in the FAILSAFE mode,
if, for example, the operating voltage to the
module fails.
Low trip:
Alarm is triggered if the signal undershoots the
threshold.
High trip:
Alarm is triggered if the signal overshoots the
threshold.
Signal threshold:
Adjustments of the signal threshold (1...90 )% are
made for channel 1 with the potentiometer P1,
and separately for channel 2 via potentiometer P2.
Hysteresis:
Adjustments of the hysteresis (1...90 )% are made
for channel 1 with the potentiometer P3, and
separately for channel 2 via potentiometer P4.
