Crane lost slew function AFE1 Code on slew drive

Crane lost slew function. AFE1 displayed permanently on screen. If cleared, drive would shut down. Checked voltage at XD24-2 24V connection on slew drive. Voltage was present but not 24V. Checked XD24-1 connection at slew drive Voltage was present but not 24V. Removed the XD24-2 wire are rechecked and voltage was 24V. Determined K600M Contactor was faulty.
If a new contactor isn’t available. K466M (motor preheat contactor) is the same and doesn’t use the 13/14 connections. This a great contactor to use to get the crane up and running.
