Nexen 5H20P-E 911317 - Manual (Page 7)

4 FORM NO. L-20210-B-1209
NOTE
For quick response, Nexen recommends
a quick exhaust valve and short air lines
between the Control Valves and the unit.
Align the air inlet ports to a down position
to allow condensation to drain out of the air
chambers of the product.
AIR CONNECTIONS
All Nexen pneumatically actuated devices require clean and
dry air, which meets or exceeds ISO 8573.1:2001 Class
4.4.3 quality. The following is a common air supply scheme used with this
product. This is an example and not an all-inclusive list. All
air circuits to be used with this product must be designed
following EN983 guidelines.
Due to bearing seal drag, the outer portion of the Con-
veyor Clutch will rotate causing hose breakage when the
Conveyor Clutch is engaged. Resting the air line against
a support that is mounted parallel to the Conveyor Clutch
center line stops this rotation.
NOTE
Use flexible hose or tubing only. Rigid pipe
or tubing when connected directly to the
Conveyor Clutch will prevent proper actuation
due to the necessary movement of the air
chamber and hose upon engagement.
Although 5H tooth clutches are air actuated with a maximum
operating pressure of 80 psi [5.52 bar], use only enough air
pressure to deliver ample torque for the application. Operat-
ing pressures in excess of 80 psi [5.52 bar] will eventually
cause accelerated bearing and O-ring seal damage.
