5.3 Behavior after power failure
After power return, the unit continues operating in the operating mode actual before power failure. In
Manual Mode (HAND), the controller regulates the temperature to the last entered set-points, while in
Program Mode (AUTO) it regulates the temperature to its set-point actually reached during program op-
eration. The power failure is noted in the event list (chap. 6.2). No error message is displayed indicating
that a power failure has taken place.
5.4 Switching on the unit
Put the main switch (2) in position I. The pilot lamp shows the unit being ready for operation.
Observe a delay time of about 30s between switching Off and On again. Otherwise an initiali-
zation problem might occur (display showing e.g. “–1999”).
In case the main switch is already in position I and yet the controller screen is dark, the chamber is in
stand-by mode. Switch on the unit by pressing any button. When switched on, the unit operates in the
operating mode entered before switching off. In Manual Mode (HAND), the controller regulates the tem-
perature to the last entered set-point, and in Program Mode (AUTO) it regulates the temperature to the
set-points reached during previous program operation.
