Warner Electric Gen 2 Clutch_Brake UniModule UM-50, UM-100, UM-180 - Manual (Page 8)

Note: If you have a Smooth Start UniModule it is
similar to a standard UniModule except
Autogaps™ are eliminated from the armatures and
a compression spring is inserted between the
armatures. This results in the armatures being in
continuous contact with the rotor and brake
resulting in light, continuous drag. This
arrangement eliminates the sudden change in
torque that results when auto-gapped armatures
engage.
No adjustment is required for the life of the unit
unless it is jarred, resulting in the armature being
moved away from the mating surface and cocking
on the spline. If this occurs, a slight pry on the
armature usually gets it back into position.
Enclosed UniModule Option
Vented Warner Electric UniModules and base
assemblies can be oriented as necessary to keep
contaminants from entering the open housing
vents.
If an Enclosed UniModule is required, an optional
Cover Kit, Warner Electric part number
5370-101-076, can be purchased separately to
enclose the open vents in the housing.
Each Cover Kit includes two (2) vent covers and
four (4) screws needed to convert a vented
UniModule to an enclosed design
(non-washdown) as shown in Figure 9.

Note: When using this Cover Kit to enclose the
module the vent covers should be assembled as
the final step.
