General
AF-Contactors are fitted with an electronic coil interface. For a given coil, this interface allows the contactor to accept a very wide voltage range. The contactor can
also be controlled by separate logic control signals from for instance a PLC. Selection of control method is done with switch S1. Control by switching voltage on A1
and A2 requires the switch in position B while control with logic signals requires the switch in position A. Use of logic control signals also requires a steady supply voltage
on A1 and A2 within the rated voltage range.
Control by switching voltage on A1 and A2 (switch S1 in position B default factory setting)
Operation of AF-contactors can be done as with conventional contactors by applying and removing voltage on A1 and A2.
Control with logic control signals (switch S1 in position A)
Use of the logic control signals also requires a steady voltage on terminals A1 and A2 within the operational limits. Minimum pulse lenght for opening and closing: 7 ms.
EN
The function of the logic control signals will no longer be guaranteed when the logic on A1 and A2 is removed. The logic control signals operates with 24 V DC and
consist of two control signals (ON and OFF_N) and a common reference (COM). To close the contactor it is enough with a control pulse at ON and to open it a removal
of voltage from OFF_N.

The functions are descibed with following diagram. "1" means 24 V DC between the control signal and COM. "0" means no voltage between the control signal and
COM.The funktion is made so that ON and OFF_N can be connected in parallel for a common ON/OFF signal. In addition to these signals the funktion limits for the
supply voltage are still valid (closing at 85% and opening at 55%), which is indecated in the diagram by high and low voltage
