3. Setting Alarm Switches
3.1
Position the SETUP SWITCH to the ALARM SWITCH
LO setting.
3.2 Using the UP (EXTEND) and DN (RETRACT) buttons,
adjust the pressure regulator to its LO ALARM
pressure.
3.3 Press the SET button and wait for the ALARM LO
LED to turn from Green to Red and back to Green
to set the ALARM SWITCH LO pressure setting.
3.4 Turn the SETUP SWITCH to the ALARM SWITCH HI
setting.
3.5
Using the UP (EXTEND) and DN (RETRACT) buttons,
adjust the pressure regulator to its HI ALARM
pressure.
3.6
Press the SET button and wait for the ALARM HI
LED to turn from Green to Red and back to Green
to set ALARM SWITCH HI pressure setting.
3.7
Position the SETUP SWITCH to the OPERATE PULSE
or ANALOG mode for normal operation.
4. Setting Feedback Output
4.1
Position the SETUP SWITCH to the OPERATE PULSE
mode.
4.2 Using the internal DN (RETRACT) push button,
adjust the actuator to its desired retracted limit
position.
4.3 Move the SETUP SWITCH to the FEEDBACK LO
setting.
4.4
Using the UP (EXTEND) and DN (RETRACT) button,
and monitoring the Analog Feedback current on
the milliammeter, adjust the output current to the
desired value (4 -12 mA) for this position.
4.5 Press the SET button and wait for the LIMIT LO &
ALARM LO LED to simultaneously turn from Green
to Red and back to Green to set the FEEDBACK LO
output current.
4.6
Position the SETUP SWITCH to the OPERATE PULSE
mode.
4.7 Using the internal UP (EXTEND) push button, adjust
the actuator to its desired extended limit position.
4.8
Move the SETUP SWITCH to the FEEDBACK HI
setting.
4.9 Using the UP (EXTEND) and DN (RETRACT) button,
and monitoring the Analog Feedback current on
the milliammeter, adjust the output current to the
desired value (12 -20 mA) for this position.
4.10
Press the SET button and wait for the LIMIT HI &
ALARM HI LED to simultaneously turn from Green
to Red and back to Green to set the FEEDBACK HI
output current.
4.11 Position the SETUP SWITCH to the OPERATE PULSE
or ANALOG mode for normal operation.
5. Manual adjustment of Pressure Regulator
WARNING
Manual adjustment must only be done when power is
removed from the unit.
NOTE: Multiple power sources possible. Do not remove
cover in the field without first removing all power from
the unit.
5.1 The Pressure Regulator output may be manually
adjusted via an 8 mm (
5 /
16
”) female hex interface
located through the top of the unit with the cover
removed.
5.2
Turn the adjustment clockwise to increase the
output pressure and counter clockwise to decrease
the output pressure.
5.3
Take care when manually adjusting the actuator as
you can damage the unit if you force the actuator
into its mechanical stops.
6. Restore Factory Defaults
The PAX1/PAXL actuator can be restored to its original
factory settings using the following procedure.
6.1
Position the setup Switch to OPERATE/ANALOG.
6.2
Simultaneously press and hold the UP (EXTEND),
DN (RETRACT), and SET buttons. For approximately
5 seconds, all of the LEDs will flash red on and off,
and then they will stop flashing.
6.3 Release the buttons and the LEDs will begin flashing
again to indicate “Restore Factory Defaults” mode
is activated.
6.4 Press the SET button to restore the PAX1/PAXL to
factory default settings. The LEDs will then return to
their normal state.
6.5 The “Restore Factory Defaults” routine will cancel if
(a) the UP (EXTEND) or DN (RETRACT) buttons are
pressed or (b) the SET button is not pressed within
20 seconds.
