Rotork Fairchild PAX1 Motor Set Pressure
Regulator User’s Manual
Product Overview
The PAX1 Motor Set Pressure Regulator is a flexible
low voltage DC powered linear actuator coupled to
one of five Fairchild precision pressure regulators
capable of controlling pressure ranges of 0-0.5 psig to
0-3000 psig and housed in a flameproof enclosure.
The unit is inherently lock in last place as the actuator
will maintains its position upon loss of electrical
power.
The PAX1 can be actuated open loop using two
optically isolated switch closure inputs (Up and Down)
to change the pressure regulators setpoint. The PAX1
will continue to change the pressure regulator
setpoint in response to the input until either of the
adjustable range limits are reached.
The PAX1 has an isolated 4-20 mA control input to
proportionally control the pressure regulator setpoint.
There is a 1-5 vdc non isolated control input as well.
In analog control mode, the unit is fail freeze upon
loss of either control signals.
The actuator features UP and DOWN push buttons
under the cover to facilitate commissioning and to
permit local control of the pressure regulator’s
setpoint. There is an 8mm (5/16”) female hex motor
drive interface under the cover to allow manual setpoint control in the case of loss of electrical power.
The actuator includes two fully adjustable 1A, 250VAC SPDT alarm relays (one High and one Low)
providing alarm function when the pressure regulator output pressure reaches critical values. The relays
are magnetically latched so the alarm switch states are maintained when the power is disconnected.
This allows accurate alarm function on systems that remove power from the actuator between
adjustments to conserve power as is typically done in solar powered installations.
The PAX1 offers an optional optically isolated electronic 4-20mA feedback output. This feedback feature
is functional for both the pulse control and analog control configurations. The unit must be powered to
facilitate the feedback output function.

Installation
The PAX1 can be mounted in any position without affecting its operation. It can be mounted to a flat
surface using the mounting holes on the actuator. An optional mounting bracket is also available. For
details, see “PAX1 Exterior Dimensions”.
Clean all pipelines to remove dirt and scale before installation. Apply a minimum amount of pipe
compound to the male threads of the fitting only. Do not use Teflon tape as a sealant. Start with the
third thread back and work away from the end of the fitting to avoid the possibility of contaminating the
regulator. Install the regulator in the air line. The inlet and outlet connections are labeled on the
regulator body under the ports. Tighten connections securely.
NOTES: Oil free air must be applied to the regulator. Use a filter to remove dirt and entrained liquid in
the air line ahead of the pressure regulator. If an airline lubricator is used, it MUST be located
downstream of the pressure regulator or performance will be affected.
Installation below ground level
Pressure Regulator Vent: For units that are installed below ground and in areas where the unit may be
under water due to flooding, the pressure regulator vent should be piped to an area where the outlet of
the pipe is located at an elevation above any possible flooding. Water entering the bonnet vent will
cause an increase in the outlet pressure in direct relation to the depth of the water above the vent. This
can cause a significant increase in outlet pressure especially in low pressure systems and may cause
dangerous system overpressure conditions.
Conduit Seal: The PAX1 is rated for limited submerged operation but the user is responsible for ensuring
water cannot enter the PAX1 enclosure through the conduit connection and conduit port. Ensure the
conduit installation is water tight at elevations that may be submerged below water. Where conduit is
prone to collect internal condensation, appropriate conduit traps, drains and seals must be employed to
prevent condensation from collecting inside the PAX1 enclosure.

Wiring
The PAX1 can be controlled with three different control interfaces. The wiring diagrams below show the
connections required to operate the unit based on the control type as well as connections to other
features such as position feedback and alarm switches.
The terminal blocks can accommodate wire size up to 1.5 mm (14 ga.). Due to safety requirements, wire
entering TB2 and TB3 terminal blocks (alarm relays) require ferrules (supplied) to provide proper
insulation for the high voltage AC connections.
Power Supply Sizing
For 12 vdc operation, the recommended power supply should have 2 amp capacity.
For 24 vdc operation, the recommended power supply should have 1 amp capacity.

1.7. Press the SET button and wait for the Limit Hi LED to turn from Green then red and back to
green to set the high pressure limit.
1.8. Position the SETUP switch to the OPERATE/PULSE or OPERATE/ANALOG to operate the actuator
normally.
1.9. When in the OPERATE/PULSE mode, the actuator will respond to external pulse control inputs
and will stop when the pressure regulator reaches either pressure limit. The LIMIT LO and LIMIT
HI LEDs will change from Green to Red when the limit is reached. The internal UP and DN push
buttons will respond likewise.
1.10. When in the TRAVEL LIMIT/LO or HI, mode, the external pulse control inputs are disabled. The
internal UP and DN push buttons will be active and will ignore the previous pressure limits so
that new limits may be set beyond the previously set limits. The LIMIT LO and LIMIT HI LEDs
will continue to operate from the previously set limits until new limits are set.
