Use with a socket – Küster/Phoenix contact motor lock

For use with a motor lock (Küster 02S 0156758, Phoenix contact EV-T2M3S-E-LOCK12V or similar) the charge controller lock outputs are configured as follows:

  • B – signal. If the motor is locked or unlocked 0V is expected, otherwise +12V.
  • R and W – Locking of motor is powered through these outputs for locking and unlocking. Locking is done with 600ms pulse. If it is detected that the motor has not functioned, the locking/unlocking action is repeated after 5 seconds. If the locking action is reverse, the wires should be swapped between R and W connections.

Connection of Küster/Phoenix contact motor:

There can be different colour codes for the wires of locking motors, therefore it is advised to consult the datasheet of the manufacturer. The connections can also be determined using a multimeter.
