Pressure Control (P1, P2, P3) Setup
• For injector systems, monitoring pressure can be
used as a way to ensure sufficient pressure has
been reached to activate injectors. The pump runs,
building up enough pressure to cause injectors to
dispense fluid. Pressure continues to build to a pre-
set maximum, activating the (user supplier) pres-
sure switch. Then an external (user supplied) vent
valve opens and pressure reduces, priming the
injector for the next cycle.
• Pressure control is an ON / OFF selection only.
1. Use the UP or DOWN arrow
button to toggle between OFF
/ C1/ P1.
2. When P1
displays,
press
ENTER
button to
save
selection.
3. If your G3 comes equipped with more than one sen-
sor input, you will automatically be prompted to
begin selecting pump control type for the next sen-
sor. Repeat steps 1 - 2 to program P2 and P3.
If P1 / P2 / P3 is selected the vent valve time is auto-
matically set to 5 minutes. If the unit is used in an
injector based system and a sensor input is not
used, the user must update the vent valve time in
advanced programming. (See Advanced Program-
ming, A-3 Vent Valve Time, page 51.)
