PLC control of AF400 and above

Make sure the dip switch is in the correct position for proper operation  See picture

below. Position A when using PLC control and position B for conventional operation (default).

High temperature readings

When concern of high temperatures on and around the contactor please check

the following (also see picture below for max permitted temperatures).

•  Make sure the connections are properly torqued.

•  Make sure the cable size is what is recommended in our catalogs.

•  Make sure the correct coil is selected for the applications.

Measurement of the resistance of the main contacts is not recommended since only

advanced equipment can be used to get a correct reading. Due to the location of the

armature the cover can reach very high temperatures (>100C). This is still within

acceptable limits.
