Remarks

•Error codes “23” and “2A(H)” may occur when applying power. This is not an error.

•To check the communication cable, remove both connectors and short the connector terminals at one end. Then measure the conductivity using a tester.

•Check the parameter and switch settings for all stations. If the settings are correct, replace the JW-20CM or JW-20RS.
