10 Alarms
10.1 Alarm functions
If a function of the unit is faulty or defective, an alarm is triggered.
Every alarm is displayed visually as well as acoustically.
The display alternates between the visual alarm and the tempera-
ture. The message is displayed until the alarm is acknowledged.
Acknowledging the alarm does not rectify the error.
The acoustic alarm is output as an alarm sound (hereafter referred
to as “buzzer”).
The unit is equipped with the following alarm functions:
n Temperature alarm
n Door-open alarm
n Power failure warning
n Alarm in case of defective display and control unit
Depending on the cause that triggered the alarm, the following
measures are required:
1 - Deactivating the buzzer
