NOTICE
For quick response, Nexen recommends a quick
exhaust valve and short air lines between the
Control Valves and the FMCBE. Align the air inlet
ports to the down position to allow condensation
to drain out of the air chambers. The Metric FMCBE
has ISO 7/1-Rc 1/8 ports.
NOTICE
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.
