XenoBRAKE hitting with
excessive force against
rollers
Excessive clearance
Brakes should be no more than
1/4" below bottom of rollers
Excessive air pressure
Reduce pressure to 60 PSI and
observe operation
28
XenoBRAKE not dropping
completely away from
roller
Brake located too high in
frame
Loosen mounting bolts to finger
tight. Actuate brake, retighten
mounting bolts while actuated.
This will align the brake

30 XenoBRAKE acts sluggish Inadequate air supply or
pressure See Note 1
Note 1
If the pressure falls more than 10% during actuation of the valve, the air supply may
be inadequate. Inspect the system for undersized supply lines, sharp bends in the
piping, restrictive fittings, a clogged filter element, or a defective pressure regulator.
Air pressure for proper XenoBRAKE operation should be a minimum of 60 PSI. The
air line size supplying solenoid valves should be 3/8" outside diameter. Between the
solenoid valve and the zone it should be 1/4" outside diameter.
