Tried entering the crane code, SCM code, and technician’s code into the crane cab display, but we crane would not accept the code. CCT and SCM were not communicating, and because the date was incorrect, the crane display would not accept any codes.
Start by switching Q131F off and then back on. Enter the SCM replacement code into CCT, and the go to Menu 2 and then to Advanced. Enter New Device and verify serial number and date and time. Switch Q131F off and back on again, and start crane.
If an incorrect code(s) have been attempted in the crane computer, it will get confused and will not accept any codes.
