How do you troubleshoot Manitowoc crane error code 123 related to hoist encoder malfunction?
Error code 123 indicates hoist encoder failure. Check encoder connections, verify 24V power supply, and inspect encoder cables for damage or moisture ingress.
Manitowoc error code 123 signals a hoist encoder malfunction in the crane's control system. Begin troubleshooting by powering down the crane and inspecting the hoist encoder connections at both the encoder housing and control module. Verify the 24V DC power supply to the encoder using a multimeter, as voltage drops below 20V will trigger this fault code.
