The module has two LEDs for informational purposes:
•
The GREEN LED on the right:
o
Solid Green indicates good pressure and nitrogen not currently flowing.
o
Blinking Green indicates good pressure and nitrogen currently flowing.
•
The RED LED on the left indicates inadequate pressure.
The trigger pressure for the module has been factory set to 3 psi +/- 0.2 psi. It takes at
least this pressure to trigger a good pressure reading. If necessary, the trigger pressure
can be adjusted through the capped hole on the top of the module. Once a good pressure
is triggered, the pressure must drop to around 0.5 psi to trigger a low pressure reading.
To adjust:
•
Set the incoming nitrogen pressure to the desired trigger pressure.
•
Remove the cap from the hole on the top of the module.
•
To set the module to trigger at this pressure, insert a regular screwdriver through the
hole and turn the screw on the top of the pressure sensor. Turn the screw
counterclockwise to lower the trigger pressure and clockwise to raise the trigger
pressure. As detailed above, the LEDs indicate good and inadequate pressure. An
audible click also occurs when the pressure sensor triggers.
•
To verify proper adjustment, watch the LED’s while disconnecting and re-connecting
the nitrogen. Make fine adjustments as necessary.
•
Re-install the cap into the hole.
