ZONESENSE DH4

OPERATORS MANUAL

5.6 Watchdog

Circuitry

The Main Control Board has watchdog circuitry external to the main processor that strobes the main
processor at intervals equal to or less than 1 second. If the 1 second interval is not met the main
processor is reset by the Watchdog circuitry, the system fault and common fault indicators will be
illuminated and the buzzer will sound. These indicators remain illuminated until reset.

If the main processor fails to successfully restart after six to twelve reset operations the processor is
held in reset. In the situation where the processor is held in reset, the buzzer will sound, the system
fault and fault indicators will flash at 0.25Hz that is On for 2 seconds and Off for 2 seconds.

5.7 Checksum

At periods not exceeding one hour, the main processor performs a checksum operation on the
application software and configuration data. If the application software or configuration data has
become corrupted then the main processor enters the reset state, the buzzer will sound, and the
system fault / fault indicators will flash at 0.25Hz that is On for 2 seconds and Off for 2 seconds.
