Installation, Operating & Maintenance Instructions
Mechanical Installation
Installation is best performed with the NAMUR
mounting kits. These kits allow direct mounting of
the Aviator™ shaft to the actuator pinion without a
coupler. The NAMUR mounting kits will work with
any actuator conforming to the NAMUR standard for
accessory mounting hole locations and pinion
dimensions. Simply attach bracket to actuator and
Aviator™ to bracket with the included fasteners. The
Aviator™ shaft features an integral alignment pin
which engages the tapped pinion hole. Automax
also offers a full line of non-NAMUR kits.
Electrical Connections
The Aviator™ features three (3) ½" NPT conduit
entries. The switches and pilot solenoid are wired to
a printed circuit board to simplify customer wiring
connections. A wiring diagram is included under the
lid. Simply make desired connections to the circuit
board using the attached screw terminal blocks.
Secure a grounding wire under the green grounding
screw. Make sure the solenoid control voltage is the
same as the solenoid electrical rating.
For hazardous locations, U.L. and National Electric
code require an approved sealing fitting within 18
inches of the switch enclosure. Sealing fittings are
not required for Division 2 non-incendive
applications. Open conduit entries must be closed
after installation using a close-up plug approved for
hazardous locations. Conduit and plugs must
engage a full five (5) threads.
Caution
To prevent ignition of hazardous
atmospheres, keep cover bolts tight
while circuits are live. Disconnect
supply circuit before opening.

Spool and Tubing Configuration
1. For spring return actuators, a 4-way spool valve
is provided with port #2 plugged. For double
acting actuators, the same valve is provided with
no plugs. Make sure the correct spool is
selected before installing tubing. (Note: the
APS2 module can be supplied on spring return
actuators to purge the spring chamber with
supply air.)
2. Make sure all air pressure is removed before
installing tubing.
3. Attach tubing according to Figures 1 or 2 below,
depending upon application. Attach supply
tubing to Port 1 and use 3 and 5 exhaust.
4. To prolong actuator life use only clean, dry plant
air. Lubricated air is not required, although it is
recommended particularly for high cycle
applications.
Figure 1
Switch Setting
1. Rotate actuator to desired position.
2. Loosen five captive cover screws and
remove lid, turning slightly while lifting.
3. To adjust the limits, lift or depress
cam against spring to disengage
splines and turn cam until switch
activates / deactivates as desired
(Figure 3).
4. Release cam, assuring that the
splines are engaged.
5. Clean base and lid flanges and
replace lid on base. Make sure wires
are NOT caught between flanges, and
tighten captive screws.
