Calibrate Calibrate Calibrate 1: 1: 1: Calibrate Calibrate Pump Calibrate
Use the Calibrate 1 screen to calibrate the linear
position sensor in the isolation fluid pump. Calibration
determines the full and empty limits of the pump to
ensure accurate volume and performance. Calibrate
the pump after the pump is removed for service or
after new system software is loaded. Follow the
steps in Calibrate the Pump, page
Calibrate Calibrate the Calibrate the the Pump Pump Pump
Before calibrating the isolation fluid pump, be sure
that air and fluid are being supplied to the system.
Put the system into Standby mode.
1. Press the Fill button. This allows fluid into the
system and begins to fill the pump. In the lower
right corner of the screen, the pump volume
indicator increases and the corresponding
number of millivolts (mV) decreases.
2. When the pump volume and mV values stop
changing, the pump is full. Press the Set Full
button. The stored mV value also displays next to
the button. The system returns to Standby mode.
3. Press the Empty button. This pressurizes the
pump and sends fluid to the spray gun. Pull the
gun trigger to dispense fluid. In the lower right
corner of the screen, the pump volume indicator
decreases and the corresponding mV value
increases.
The screen lists the solenoid valve that the
system will use to feed fluid into the system. The
valve corresponds to the color selected for the
current preset.
4. When fluid stops flowing out of the gun, release
the trigger. Press the Set Empty button. The
stored mV value also displays next to the button.
The system returns to Standby mode.

Calibrate 2: 2: 2: Air Calibrate Calibrate Air Air and and Fluid and
Use the Calibrate 2 screen to adjust the calibration
value of the air and fluid. (Default value is 1000 mV.)
Calibrate the air and fluid:
• When the actual air or fluid pressure does not
match the target value on the Home screen and it
seems like it should.
For example, when air is applied to the system and
the system is in Standby mode, both target and
actual values should be 0.
• After replacing the electro/pneumatic regulator
(V2P) (415).
• After replacing the V2P cable.
