5-WAY CONTROL VALVE
1.
If the brake is to be set and the clutch is to be
OFF
when the
solenoid is de-energized, connect the port marked
4
to the
brake and the port marked
2
to the clutch (See Figure 6).
2.
Connect the brake air supply line to the port marked
5
and
the clutch air supply line to the port marked
3
(See Figure 6).
3-WAY CONTROL VALVES
1.
Connect a 3-Way N.O. Control into the brake inlet port and
a 3-Way N.C. Control into the clutch inlet port (See Figure
7).
2.
Connect an air supply line to the inlet port (marked
IN
) on
the top of the 3-Way N.O. Control and an air supply line to
the inlet port (marked
IN
) on the side of the 3-Way N.C.
Control (See Figure 7).
NOTE
When a 3-Way N.O. Control is de-energized, air flows
directly to the brake. When a 3-Way N.O. Control is
energized, air exhausts from the brake.
When a 3-Way N.C. Control is de-energized, air exhausts
from the clutch. When a 3-Way N.C. Control is energized,
air flows to the clutch.

LUBRICATION
NOTE
Pneumatically actuated devices require clean, pressure regulated, and lubricated air for maximum performance and long
life. The most effective and economical way to lubricate Nexen Clutch-Brakes is with an Air Line Lubricator, which injects
oil into the pressurized air, forcing an oil mist into the air chamber.
Locate the lubricator above and within ten feet of the Clutch-Brake, and use a low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.
LUBRICATOR DRIP RATE SETTINGS
NOTE
These instructions and settings are for Nexen supplied lubricators only. They do not apply to lubricators not supplied by Nexen.
1.
Close and disconnect the air line from the unit.
2.
Turn the Lubricator Adjustment Knob counterclockwise three
complete turns.
3.
Open the air line.
4.
Close the air line when a drop of oil forms in the Lubricator
Sight Gage.
6.
Turn the Lubricator Adjustment Knob clockwise until closed.
7.
Turn the Lubricator Adjustment Knob counterclockwise one-
third turn.
8.
Open the air line to the unit.
5.
