The way to confirm is pushing the “RESET” key (or by an exeternal contact, When parameter R.MD is set to 1. according to the setting of setup parameter DIS). The confirming operation is not accepted during PV exceeds SP (point D). State of output The limit output relay is always energized at power on (point A) (NC terminal : OPEN, NO terminal : CLOSE) and “OUT” lamp is off, except relay is de-energized whenever “OUT” lamp is on.
