Power Supply Units
Section 3-4
3-4-3 Wiring Other Terminals
The Power Supply Units provide a START input and a RUN output. These termi
-
nals can be used to help control system operation.

START Input
The START input terminals are short-circuited at the factory with a short bar. The
short bar can be removed and the terminals wired to a 10-mA, 24-VDC external
input to control PC operation. When these terminals are open, PC operation will
stop.
RUN Output
The RUN output terminals will be ON (closed) when the PC is operating in RUN
or MONITOR mode. These terminals can thus be wired to provide an external
signal indicating the operating status of the PC, such as is used in the emergen
-
cy stop circuit in the next section.
