Calibration Procedure
Calibration allows iControl to learn the characteristics of the machine brake.
1. Verify that the iBox Safety OK LED is solidly on.
2. Set the iBox Learn switch to ON.
3. Place the iBox Inspection switch in the INSP position. Verify that the iBox displays
Machine Room Insp.
If the iBox does not indicate that you are in Machine Room Inspection even though the Inspec-
tion switch is in the INSP position, another inspection mode (i.e., cartop inspection) is probably
active. Other inspection modes must be OFF before Machine Room Inspection can be activated.
4. Display the Brake > Control tab (Con-
figuration > Brake > Control tab).
5. Set Pick voltage and Hold voltage as
shown on your job prints.
6. For now, set Releveling voltage and
Weakening voltage to the same value
as Pick voltage. (This parameter can be
fine tuned during final adjustment.)
