An alarm (
can continue running without any restrictions. Alarms are triggered, for
example, if the actual value of a parameter deviates too much from
the setpoint or the door is open for too long. Alarms are indicated
with the alarm symbol and an acoustic signal. Alarm messages can be
confirmed by pressing any key. If an alarm is not confirmed manually,
it disappears as soon as the condition that triggered the alarm is no
longer met.

HIGH / LOW )

A parameter alarm is triggered if the actual value of a parameter
deviates too much from the setpoint after a set waiting time. In
the example on the left, the temperature is too high. The maximum
permissible deviation from the setpoint and the waiting time are set in
the factory and cannot be changed.
An alarm is only triggered if the actual value of the
parameter does not change for a certain period of
time. If there is a fluctuation, the counter for trig-
gering the alarm is reset.
