b14
KEYPAD
WDOG
This watchdog is provided for an external keypad or other devices
where a break in the communication link must be detected.
The watchdog system can be enabled and/or serviced if this bit is
changed from zero to one while the control word is enabled.
Once the watchdog is enabled it must be serviced at least once every
second or a ‘Watchdog’ trip will occur (trip code 30). The watchdog is
disabled when a ‘Watchdog’ trip occurs, and so it must be re-enabled
when the trip is reset.
