WATCHDOG

The Watchdog contacts are also hosted on the power supply board. The Watchdog facility provides two output
relay contacts, one normally open and one normally closed. These are used to indicate the health of the device
and are driven by the main processor board, which continually monitors the hardware and software when the
device is in service.
