Table 9-1. Cs4 Control Signals - ABB ControlIT 53MC5000 Instruction Manual

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:

Table 9-1. CS4 Control Signals

Control
Signal
AI0 - Auto This analog signal is gated through as the AO0
Input 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.
AI1 Not used.
AI2 - Alarmed It is the designated input variable that is
Variable checked to be within acceptable process limits.
AI3 - Tracking This analog input signal value becomes the
Input Station Output value when the Force Output
Tracking contact input is open and datapoint
L119 (Enable Output Tracking) is configured to a
1.
AO0 - It is the selected analog 4-20 mA output signal
Station that is sent to the final control element.
Output
AO1 Not used.
DI0 - Force When an open contact is present on this input,
Output the Station Output value is forced to match the
Tracking Tracking Input value when datapoint L119
(Enable Output Tracking) is configured to a 1.
DI1 - Auto When a closed contact is present on this input
Enable and Auto is selected with the A/M faceplate push
button, it enables the Auto Input analog signal
value on AI0 to be selected as the AO0 Station
Output.
DO0 - Process This contact is closed when the Alarmed
Alarm 1 Variable value is not within the C103 value
setting (Alarm Limit 1 datapoint); otherwise, the
contact is open.
DO1 - Process This contact is closed when the Alarmed
Alarm 2 Variable value is not within the C104 value
setting (Alarm Limit 2 datapoint); otherwise, the
contact is open.
