Lamella roof normalizing function - GF77.20-P-3006GH

MODEL 163 with CODE (417a) Lamella roof 

The internal counter status is linked with the actual position of the lamella roof in the analysis electronics of the right lamella roof motor (M12/3)  by means of normalizing  .

Normalizing has to be performed if the lamella roof has been separated from the supply voltage, if a fault has occurred in the position measurement, or if the lamella roof has been opened by means of the emergency operation  .

Emergency operation 

If the drive is faulty, the lamella roof can be opened and closed manually using a steel crank.

(See Owner's Manual)

Performing normalization 

(only after disconnecting and re-connecting supply voltage).

Press lamella roof switch (S13/4)  forward for about 0.5 s when the lamella roof is closed.

Re-normalizing in constant operation 

If the lamella roof switch (S13/4)  is moved in the "closed" direction for longer than 15 s, re-normalizing  is activated if the analysis electronics subsequently detects blocking for at least 0.5 s.
