Voltage Source
Voltage User
Moving: approx. 2.5V Not Moving: <1V or 4.75V
Steering Encoder
CM
Part of the steering request when the encoder is rotated. It is a square wave signal identical to CHB-E2 but different phase. The TM uses the phase relationship of the two channels to determine whether CW or CCW steering is requested. The number of pulses is used to determine the total movement requested.

Steering Encoder
CM
CHB-E2
Part of the steering request when the encoder is rotated. It is a square wave signal identical to CHA-E2 but different phase. The TM uses the phase relationship of the two channels to determine whether CW or CCW steering is requested. The number of pulses is used to determine the total movement requested.

B+EPO
B+ provided through the normally closed EPO Switch (S21), when the Key Switch (S1) is closed, to the OTM cables, and to feed B+ to the K1, K2, and K3 relay coils. The status of the EPO switch is monitored by the CM and TM.
