APS2 Module

Installation Instructions

The Automax APS2 may be installed very easily to any

SuperNova series spring return actuator, with the

hardware supplied with the module.

1. Place each o-ring provided into the o-ring bore on

the rear of the module (the side with two large

ports.) Each o-ring should be completely seated

in the bore.

2. Place the actuator with the two ports facing you,

and the stem pointing up. Orient the APS2

module with the o-rings toward the actuator, and

the breather vent facing left.

3. The module will be mounted to the actuator, using

the two diagonal tapped holes next to the ports.

Align these holes with C-bored through holes of

the module, and mount with screws provided.

Directional valves may be line mounted to the APS2

by connecting the appropriate valve port to the 1/4"

NPT supply port on the front of the APS2. In addition,

the module supports the NAMUR mounting standard.

In this case, the directional valve should be positioned

such that the correct port is covering the APS2 supply.

Tapped holes are provided for NAMUR mounting.

Two o-rings are required for this arrangement

(2mm x 16mm o-ring size).

Operation

The Automax APS2 module works with remote line

mounted solenoid valves and diverts exhaust air from

between the pistons into the spring chamber. This

prevents corrosive atmosphere from being pulled into the

spring chamber.

Note: The APS2 can not be used in conjunction with

a positioner.

Temperature: -20°F to 180°F

Pressure: 20psig to 100psig

Media: Dry or lubricated non-corrosive gas

compatible with nitrile and silicone seals.

Exhaust: C

∨

= 0.8 (Spring Return Stroke)

Inlet: C

∨

= 1.2 (Pressure Stroke)

Actuator Pressurized

Pressure at supply port presses edge of diaphragm to

ring, allowing air flow around and under ring. Air flows

into piston port of actuator, compressing springs. Spring

side air exhausts out vent to atmosphere.

Actuator Exhausted

Supply pressure is released and springs push on piston

to force air out piston port. Pressure forces diaphragm

up, covering supply port and revealing spring port. Air

flows into spring port, allowing clean air in instead of

contaminated air from the environment.
