Displayed at startup by all CPUs if the watchdog timer on the board is disabled. This timer is a hardware device that asserts SYSFAIL on the VME bus (which drops high power) if the CPU halts or gets hung. The board that has failed should light its SF LED. This message is also displayed whenever a user task is started from the monitor and the watchdog timer is disabled.Do not use this system. The watchdog timer must be enabled for safe operation of your system. The watchdog timer setting on the AWC cannot be changed by you. Report this problem to Adept Customer Service.
