8.2 CS3 CONTROL SIGNALS
Loading CS3 connects the 53MC5000 Controller function blocks for operation as a Ratio (PID) Con-
troller. As shown in Figure 8-1, CS3 provides nine control signals which are described in Table 8-1:

DI0 - Force
Output
Tracking When an open contact is present on this input,
the Control Output valve is forced to match the
Tracking Input value when datapoint L119
(Enable Output Tracking) is configured to a 1. TB2-1 (+)

DI1 - Ratio
Enable When a closed contact is present on this input,
the operator can select Ratio operation with the
R/L faceplate push button. TB2-3 (+)

DO0 - Process
Alarm 1 This contact is closed when the Process
Variable value is not within the C103 value
setting (Alarm Limit 1 datapoint); otherwise, the
contact is open. TB2-5 (+)
