5.7.7 CHAIN DRIVE SAFETY BRAKE WIRING
The actuation of a Safety Brake is required in the event of a drive chain breakage, to prevent the curtain from falling.
If using this controller in conjunction with the GCDO-22-23 chain driven operator a mechanical safety brake must be

Connection is not polarity sensitive.
5.7.5 ENCODER AND INTERNAL OPERATOR SOLENOID BRAKE WIRING
GCDO-22-23-VS model uses a
solenoid brake which needs to
be wired along with the
Encoder. For this model:
1. Connect one end of the
internal operator solenoid
brake cable to X14 relay Pin
11.
2. Connect the other end of the
internal operator solenoid
brake connection to the N of
the Blue terminal block.
3. Connect a link wire between
X14 relay Pin 10 and L.
Encoder cables are supplied fitted
to PCB connectors, ready to swap
