3.7.6 Signalling relays
CAUTION
The signalling relays err and "option" are used to output error messages and may not
be used for safety-relevant functions.
The signalling relays may only be parameterised by an electrically skilled person.
Both relays can be parameterised as normally-closed or normally-open contacts:
Relay
Normally-open
Normally-closed
option
S3_7 off
S3_7 on
err
S3_6 off
S3_6 on
err is switched in every error state that stops a lifting movement.
option is freely parameterisable. Parameterisation is dependent on the switch position
