Power interruption
You can use an external relay (CR in the following figure) to form an emergency
stop circuit that shuts down the system when PC operation stops. This can be
achieved by wiring the RUN output from the Power Supply Unit on the CPU Rack
as shown below.
A sequence circuit is built into the PC to handle power interruptions. This circuit
prevents malfunctions due to momentary power loss or voltage drops. A timing
diagram for the operation of this circuit is shown below.
