8.5 Performance during and after power failure and shut down
In the event of power failure, the battery maintains the controller functions. The controller display is dark
and can be activated for 5 seconds by pressing any button. The refrigerating machine is out of operation..
The unit’s refrigerating function can be maintained through the optional CO2 emergency cooling (chap.
11). The zero-voltage relay alarm output (8) (chap. 10.10) is switched for the whole duration of the power
failure.
After the power returns, each freezer turns on with an individual firmly assigned delay of max. 180 sec-
onds to prevent current spikes in the customer's electricity supply system by simultaneously switching on
several devices.
The controller counts down the time until restart in seconds.
Figure 37: Time until restart
After the power returns or when turned on by hand, the freezer regulates the temperature to the last en-
tered set point.
All settings and set point values remain in the memory during power failure after power off.
