Assembly and Mounting Instructions
SPECIAL NOTES
Note
Mounting of the Axiom requires a StoneL mounting kit specific to the actuator the Axiom is to be mounted to.
Note
It is recommended that thread lubricant or anti-seize be used on the Axiom Body Screws (Item# 3) prior to assembly.
Note
Referring to Step 3 below. Depending on the version of Axiom, the DA/SR Plug (Item# 5) may be located in the Axiom Body
(Item# 4) or the Air Manifold Plate of the mounting kit (Item# 14).
Note
In high cycle or high vibration applications, blue Loctite® may be used on the Air Manifold Mounting Screws (Item# 11) and
the Visual Indicator Drum Retaining Screw (Item# 9).
Note
It is highly recommended that exhaust ports E2 and E3 be fitted with low restriction mufflers or breather vent caps to
prevent ingestion of water and debris into the pneumatic valve.
Note
For epoxy coated aluminum models, conduit seal-offs are required with in 18” of the unit. Seal-offs are not required on
models with a stainless steel housing.
1. Refer to Axiom Assembly Drawing located on Page 7 when performing mounting and assembly procedures.
2. Remove Axiom unit from shipping container. Ensure all listed items are present.
3. Determine if the actuator the Axiom is to be mounted on is double acting (DA) or spring return (SR). Ensure the DA/SR Plug
(Item# 5) is in the correct position. (See Detail - A on Page 7). If the DA/SR Plug is in the incorrect position, gently remove plug with
a pair of pliers and insert into the proper orifice. (Note: For aluminum AX units, the DA/SR Plug is included in the manifold plate of
the mounting kit. If there is a black DA/SR plug in the body of aluminum AX housing, this needs to be removed and discarded. For
stainless steel AX units the DA/SR plug is located in the body of the stainless steel AX housing.)
4. From the mounting kit package, locate the Air Manifold Plate (Item# 14). Place the Air Manifold Plate on the actuator. Using an M4
allen wrench, fasten down with the four Air Manifold Mounting Screws (Item# 11). Torque screws to 25 - 30 in.lbs (2.8 - 3.4Nm).
5. Place Visual Indicator Drive Block (Item# 10) into slot on the actuator shaft. Place Visual Indicator Drum Coupler (Item# 8) onto the
Visual Indicator Drive Block. Next, place the Visual Indicator Drum (Item# 7) onto the Visual Indicator Drum Coupler. Align the
holes in all three items with the the threaded hole in the actuator shaft and fasten down with the Visual Indicator Drum Retaining
Screw (Item# 9). Leave screw loose in order to facilitate indexing of the visual indicator.
6. With the actuator in the closed position, center the Visual Indicator Drum until the “OPEN” quadrant is centered between the “V.I
INDEX” markings on the AIr Manifold Plate. (See Detail - B on Page 7). Tighten down with the Visual Indicator Drum Retaining
Screw 15 - 20 in.lbs (1.7 - 2.3Nm).
7. Verify Air Manifold Plate Orifice O-rings (Item# 12) and Visual Indicator Cover O-ring (Item# 13) are in place.
8. Place the Visual Indicator Cover (Item# 6) over the Visual Indicator Drum assembly then set the Axiom Body (Item# 4) in place.
With an M5 allen wrench, torque the Axiom Body Screws (Item# 3) to 8 - 10 ft. lbs (10.8 - 13.5Nm).
9. After all wiring and sensor setting procedures have been completed, install Axiom Cover and tighten the Axiom Cover Lock set
screw (Item# 2).

AS-Interface Standard Addressing Sensing & Communications Module
AS-Interface Module w/Standard Address Specifications Max. Output Current: 160mA (4 watts; both outputs combined
Communication Protocol: AS-Interface v3.0
ID/IO Codes:
ID = F; IO = 4; ID1 = F; ID2 = E
Configuration:
(2) Discrete Inputs (Sensors)
Default Address: 00
(2) Auxiliary Discrete Inputs
Bit Assignment: Inputs Outputs
(2) Discrete Outputs (Solenoids)
Bit 1 = Aux Input 1 Bit 1 = Not Used
Voltage:
26.5-30.6 VDC (AS-I Voltage)
Bit 2 = Aux input 2 Bit 2 = Not Used
Bit 3 = Green LED Bit 3 = OUT 1
Output Voltage:
24 VDC
Bit 4 = Red LED Bit 4 = OUT 2
Current Consumption: 42mA (1) 0.5w coil; 64mA (2) 0.5w coils

To Bench Test an AS-Interface Sensing & Communications Module:
To test sensors, use a 24 Vdc power supply. No series load resistor is required. Operate actuator to the closed position. Apply power
across the “ASI+” and “ASI-” terminal points. Press and hold “Closed Set” button until “Closed LED is lit (two seconds). Release
button. Operate actuator to the open position. Press and hold “Open Set” button until “Open LED is lit (two seconds). Release button.
Set points are retained even after power is removed. A functioning AS-Interface network is required to test communications.
WARNING:
DO NOT APPLY EXTERNAL POWER TO THE OUTPUT TERMINALS. THIS WILL CAUSE PERMANENT DAMAGE TO THE UNIT
