2) WITH THE CONNECTION FOR OPTIONAL WIRED SWITCH
Do this operation only in case of emergency, if all remote controls are no longer operating.
To delete the memory we have to access the connection for optional wired switch (cable
3). See Electrical Connections diagrams on pages 35 and 36 for reference.
The sequence of this operation is the following:
1) Disconnect the control unit from the power supply, via the main switch for example.
2) Connect the cable 3 to phase or neutral.
3) Connect the control unit to the power supply: the motor rotates briefly in one direction.
4) Disconnect the control unit from the power supply for at least 4 seconds.
5) Connect the control unit to the power supply: after around 4 seconds the motor
performs one brief rotation in one direction and then a longer one in the opposite
direction.
6) Disconnect the control unit from the power supply unit.
7) Separate cable 3 from phase/neutral. Insulate cable 3 in an appropriate way before
reconnecting the power supply.
At this point it is possible to proceed with the setting of the first remote control.
