Brake Operation
With the assembly mounted on the gearbox, check the
operation of the clutch brake as follows:
With no electrical power or pressure connected, check that
the coupling 6 is free to rotate.
With air pressure connected to the solenoid valve 39 and the
solenoid de-energised, check that the coupling cannot be
rotated (i.e. brake on).
With air pressure connected and the solenoid energised,
check that the coupling can be rotated back and forth as far
as the gear backlash allows (i.e. brake off).
Note: The solenoid can be damaged if it is connected the
wrong way round. Ensure correct polarity before applying
power.
