  • Page 10 If a feedback contact is to be monitored, it must be connected between Y1/Y2 instead of the link. If the correct clock signal is read by the G1501S, the outputs of the G1501S are activated. If a different signal is read, the outputs of the G1501S are immediately de-energised. The contacts 13- 14 and 23-24 are opened, the feedback output Y7 is deactivated.
  • Page 11 If the fail-safe sensor is enabled, the clock signal is applied to the output of the fail-safe sensor after a delay and is read by the G1501S via the terminal S43. If the clock signal is read by the G1501S, the G1501S outputs are activated at the terminals Y1 and Y2 after pressing and releasing the start button.
