That’s the only thing I can think of that would cause the car not to take a 5th floor car call or hall call, assuming CLC Adjustment 2 is set to 5. Go to Selector Parameter 5 and make sure there is a learned value for the floor. It’s possible you have to do another hoistway scan if the floors served parameters were not set correctly before you did the first one. Can you place a 5th floor call with CLC Adjustment 85?
