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) 1⁄2" 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 codes 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.

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.

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.

Lubrication

All Aviator™ spool valves are pre-lubricated and will operate dry (with no additional lubrication). The use of lubricated air will not interfere with the Aviator’s functioning.

If air lubrication is used, the oils listed below are popular, easily obtainable fluids that are recommended for use with the Aviator™ Spool valve: Gulf Harmony 47, Mobil DTE Medium, Shell Tellus 29, Texaco Rondo B, Sohivis 47 and Sunnis 921. Many other lubricants are acceptable providing they do not contain detergents that will attack Nitrile or Viton Seals.
