NOTE: Refer to Figure 4
1. If the brake is to be set when the solenoid is de-ener-
gized, connect the port marked 2 to the brake and the
port marked 4 to the clutch.
2. Connect the air supply line to the inlet port (marked
1).
FIGURE 5
For a faster response, Nexen recommends a quick exhaust valve and short air lines between the Control Valves and the FMCB.
Align the air inlet ports to a down position to allow condensation to drain out of the air chambers. The FMCB has 1/8 - 27 NPT
ports.

directly to the brake. When a 3-Way N.O. Control is en-
ergized, air exhausts from the brake.
When a 3-Way N.C. Control is de-energized, air exhausts
from the clutch. When a 3-Way Control is energized, air
flows to the clutch.
