AIR CONNECTIONS
The following are common air supply schemes used with
this product. These are examples and not an all-inclusive
list. All air circuits to be used with this product must be
designed following EN983 guidelines. All Nexen pneumatically actuated devices require clean,
dry air that meets or exceeds ISO 8573.1:2001 Class
4.4.3 to quality.
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.
NOTE
Use flexible hose or tubing only. Rigid pipe
or tubing connected directly to the Conveyor
Clutch will prevent proper actuation due to the
necessary movement of the air chamber and
hose upon engagement.
Due to bearing seal drag, the outer portion of the Conveyor
Clutch will rotate, thus causing the air line hose to break
when the Conveyor Clutch is engaged. Rest the air line
against a support mounted parallel to the Conveyor Clutch
to stop this rotation and prevent hose breakage.
