Attached functions
Power failure countermeasure:The data is backed up in non-volatile IC memory.
Self diagnosis:
The CPU is monitored by a watchdog timer, and whenan abnormal status is found on the CPU, the unit isswitched to warm-up status after turning all outputs off.
Unconnected sensor detection:
If pulses are not detected for a constant period (1000sec),
the unit will revert to the initial status (0Hz).
