alarms can be controlled by events like e.g. min/max-value.
Function principle of alarms / relays
Alarm / Relay x
Deactivated, instantaneous value, min/max-value
Switching threshold
Threshold / limit value of the change-over
Hysteresis
Broadness of the window between the switching thresholds
Working principle
Operating current / Quiescent current
7. Alarms / Relays
Operating current
By operating current the alarm S1-S2 is
off
below the threshold and
on
on reaching the
threshold.
