Troubleshooting KMFM Control System
Transmitter and Receiver Errors
If the crane does not operate, ensure that both the transmitter and receiver are on. Try disconnecting power to the crane receiver then reconnecting.
Run the crane using the wire pendant to confirm that the problem is the wireless unit.
Check that the green transmit light on the transmitter and the green receive light on the receiver light up when a function is selected.
Check for error codes and correct as necessary.
NOTE!
The green transmit light is located inside the transmitter.
Check that all connectors are secure.
Check for bent pins on the receiver connectors.
If the transmit and receive LEDs are both lit when a function is selected and no error codes are given contact Liftmoore, Inc. for further information.
