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.
Detecting unconnected sensor:
If pulse is not detected for a constant period, the unit willrevert to the initial status (0Hz).
(Low pulse: 1000sec or 100sec, Frequency: 1sec)
