Potentiometer analog setting

As easy to operate as our traditional model, the ACN-100 series.
Can set and change the SV easily using an analog setting unit (potentiometer).

Auto-reset function

The ACN-220 (PD control) comes with an Auto-reset function.

Control action can be changed with the DIP switch.

Control action: PD or ON/OFF control is selectable with the DIP switch.

Model

Model	(1) Control Action and Alarm Type can be selected with the DIP switch. When shipped, user specified Control Action and Alarm Type have been set on the controller. (2) For the Alarm Action with Standby, “H” is attached to the end of the model name.

Alarm Function

Alarm output

The Alarm action point is set as a ±deviation from SV (except Process alarm). When the PV is out of the range, the alarm output turns ON or OFF (in the case of High/Low Limit Range alarm).
If the Alarm Function is specified, one type can be selected with the DIP switch: No Alarm Action, High Limit alarm, High Limit with Standby alarm, Low Limit alarm, Low Limit with Standby alarm, High/Low Limits alarm, High/Low Limits with Standby alarm, High/Low Limit Range alarm, Process High alarm and Process Low alarm.

Alarm Function

Alarm output: Setting by the deviation from the SV (except process alarm).
If the input goes outside the range, the output turns ON or OFF (in the case of High/Low limit range alarm).
Alarm type: If any alarm type (except no alarm action) is specified, the alarm type can be changed with the DIP switch. (Default: Customer specified alarm type)
