Electric Point Machine Westinghouse Style M70 MKIII TMG E1583

2.4 Wiring

The internal wiring is in high temperature PVC insulated wire, 50/02.mm (70/.0076) for

motor circuits and 30/0.2mm (40/.0076) for control and detection circuits. Wiring

between the terminal board and the circuit controller is protected by a rigid PVC

conduit. A 51 mm (inside diameter) flexible conduit connection is provided near the

terminal board for incoming wires.

The point machines are wired to short-circuit the detection relay(s) while the detection

is open. If this is not required, remove the three links between 9-8 and 9-4, 9-4 and 8-

3, 8-3 and 8-7 on the detector switches.

The internal wiring diagram for the point machine is given in Figure 2.4.
