Note: Repeated control using “Discharge halt input” input should be carried
out at 1 Hz or less.
Continuous discharging for 2 sec. or more is required for stable
sensing of check output.
If using with repeated control operations that include discharges of 2
sec. or less, use continuous discharges of 2 sec. or more to check the
check output when carrying out maintenance.

In the state that operation is stopped due to an error detection, open
0 V of the power supply from short-circuit state to cancel ERROR.
