9.2 CS4 CONTROL SIGNALS
Loading CS4 connects the 53MC5000 Controller function blocks for operation as an Automatic/
Manual Station. As shown in Figure 9-1, CS4 provides eight control signals which are described in
Table 9-1:

Signal
AI0 - Auto
Input This analog signal is gated through as the AO0
Station Output if DI0 and DI1 are both closed
(DI0 closed = no Output Tracking and DI1
closed = Enable Auto). Also, A (Auto) must be
selected with the A/M faceplate push button. TB1-1 (+)
