6 Operation of the controller
Front view of controller:
6.1 Switching on the operating voltage
The controller is started by means of a control switch provided by the
customer.
The first time the controller is started, pre-programmed setting values
are used which at later point can be adapted for individual
requirements.
If alarm “AL 2” (temperature in refrigerated chamber too high
or too low) is displayed when the controller is switched on, this
can be cleared by pressing the
key.
6.2 Display
During normal operation the current cold store temperature is
displayed. It is measured with cold store sensor T1.
In the event of an alarm, the most recent alarm message (e.g. AL1)
and the cold store temperature are displayed alternately.
