6.3 Performance during and after power failure

During a power failure, all controller functions are shut down. The optional zero-voltage relay alarm output

(chap. 19.4) is switched to alarm position for the whole duration of the power failure.

After the power returns, all functions return to the same status the chamber had before power failure. .

The controller continues to function in the original operating mode it was in previously before the power

failure occurred.

• Performance after power failure in “fixed value” operation mode

All functions return to the same status the chamber had before power failure. The set-points are

immediately resumed.

• Performance after power failure during time program operation

The program is resumed at the point where the interruption occurred with the latest set-points reached

during the program run.

• Performance after power failure during week program operation

The week program continues with the values corresponding to the current time.

If the temperature has dropped below the alarm limit during power failure, confirm the alarm with the

RESET button as soon as the correct values are reached again (chap. 14.3).
