1. Overview
The PAX1 Motor Set Pressure Regulator is a
flexible linear actuator coupled to Fairchild
precision pressure regulators and capable of
controlling pressure ranges of 0-0.5 psig to
0-3000 psig all housed in a flameproof enclosure.
The unit is inherently lock in last place as the
actuator will maintain its position upon loss of
electrical power.
Power input options include 12-24 VDC or universal AC input
95-250 VAC 47-63 Hz.
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’s setpoint in response to the
activated 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’s setpoint.
In analog control mode, the unit is fail freeze upon loss of
the control signal.
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 8mm
(5/16”) female hex motor drive interface under the cover
to allow manual setpoint adjustment in the case of loss of
electrical power.
WARNING: The cover must not be removed in
the presence of a hazardous classified combustible
atmosphere when power is present. Multiple power
sources are possible including those operating the
analog inputs, pulse inputs, alarm relays and feedback
circuits.
The actuator includes two fully adjustable 1A, 250VAC
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
4-20mA 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.
The PAX1 can also be controlled via Modbus RTU digital
communications over an optional optically isolated
RS-485 network. The Modbus communications include a
full featured command set allowing control, monitoring,
commissioning and diagnostics capability over the digital
communication.

Hazardous Area (Classified) Conditions of use
• Under certain extreme circumstances, the non-metallic
parts incorporated in the enclosure of this equipment
may generate an ignition-capable level of electrostatic
charge. Therefore the equipment shall not be installed in
a location where the external conditions are conducive
to the build-up of electrostatic charge on such surfaces.
In addition, the equipment shall only be cleaned with a
damp cloth.
• Contact the manufacturer if information of flameproof
joints is needed.
3. 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”.
Pressure Regulator Piping
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 vent 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 (Analog, Pulse & Modbus). The wiring diagrams,
Figures 3-8, 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 high voltage AC connections.
The AC powered PAX units also require crimp ferrules for
wires entering the terminal block at connection 11 & 12.
Crimp ferrule onto wire, then
clamp it in the terminal block.

Setup switch
Eight position rotary SETUP switch, for setting control type
and configuring travel limits, Alarm points and Feedback
calibration.
Configuration DIP switches
SW1 selects 4-20 mA for analog control input or Modbus
communication control.
SW2, Isolate: The Pulse control inputs are isolated from
the DC power supply providing power to the unit and must
be powered from a separate external power source. (See
Figure3). This is useful for long runs of the control lines to
eliminate ground loops with local power supply and control
equipment.
SW2, NO: The Pulse control input circuit is connected to the
DC power supply providing power to the unit. No external
control loop supply required. One side of the control switches
must be connected to the – power supply connection.
(See Figure 4).
Push button switches
UP: Moves the pressure regulator setpoint to a higher
pressure.
DN: Moves the pressure regulator setpoint to a lower
pressure.
SET: Used in conjunction with the rotary SETUP switch to
set the pressure limits, alarm points, and analog feedback
calibration.
LED indicators
PWR: Green, Supply voltage is between 11 and 30 VDC.
Red, Voltage is less than 11 VDC or greater than 30 VDC.
LIMIT HI: Green, Hi limit not reached, thrust rod will move in
both directions. Red, Hi Limit reached, thrust rod will move
down only.
LIMIT LO: Green, Lo limit not reached, thrust rod will move
in both directions. Red, Lo Limit reached, thrust rod will move
up only.
ALARM HI: Green, Hi Alarm not reached, Hi Alarm relay not
energized. Red, Hi Alarm reached, Hi Alarm relay is energized.
NO contact is closed.
ALARM LO: Green, Lo Alarm not reached, Lo Alarm relay
not energized. Red, Lo Alarm reached, Lo Alarm relay is
energized. NO contact is closed.

Figure 12
Speed potentiometer
20 turn. Adjusts actuator speed from 1.2 mm/min to
60 mm/min.
In order to get the utmost performance from the PAX1, the
motor speed range can be adjusted beyond its stall speed.
The actual maximum attainable operating speed will depend
on the supply voltage, and the maximum required thrust.
The maximum required thrust will depend on the pressure
regulator model and its pressure range.
If the motor stalls before the maximum pressure range can be
attained, reduce the motor speed.
Damping potentiometer
1 turn. Adjusts start and stop ramp speed rate. Use this
control to prevent hunting of the output about the setpoint.
Manual control
The actuator can be manually moved by manually turning
the motor through an 8mm (5/16”) female hex socket
located through the hole in the top PCA cover near the SET
button. Turning the motor clockwise increases pressure,
counter clockwise decreases pressure. Take care not to drive
the actuator into its mechanical stops and over torque the
gearbox as damage to the gearbox may result.

under the cover, adjust the pressure regulator to its
highest desired output pressure.
1.8 Press the SET button and wait for the Limit Hi LED
to turn from Green to Red and back to Green to set
the high pressure limit.
1.9 Position the SETUP switch to the OPERATE/PULSE
or OPERATE/ANALOG to operate the actuator
normally.
1.10 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 (EXTEND) and DN
(RETRACT) push buttons will respond likewise.
1.11 When in the TRAVEL LIMIT/LO or HI, mode, the
external pulse control inputs are disabled. The
internal UP (EXTEND) and DN (RETRACT) 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.
2. Setting Analog Control Current
2.1 Connect a 4-20 mA signal source to the 4-20 mA
input terminals.
2.2 Turn on power to the unit.
2.3 Set SW1 to 4-20 mA.
2.4 Position the SETUP SWITCH to the TRAVEL LIMIT LO
setting.
2.5 Using the UP (EXTEND) and DN (RETRACT) buttons

to turn from Green to Red and back to Green to
set the high travel limit and corresponding control
current.
2.12 Position the SETUP switch to the OPERATE/
ANALOG to operate the actuator from the Analog
Control input terminals.
2.13 ERROR SIGNALS – If both the Hi Limit and Lo
Limit LED’s blink red, then an error has occurred
in setting the Analog Control signal. The most
common error is setting the Lo and Hi Limit and
forgetting to change the control current. In this
case, the Lo Limit and Hi Limit are set with the same
current. This signal also occurs if the difference in
control current between the Lo Limit and Hi Limit is
less than 4mA. Correcting either the Lo Limit or Hi
Limit setting or both will resolve the problem.
