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

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.
Note
The fluid pressure will be whatever the
active preset is currently set to. It may
be desirable to turn it down. Changing to
Preset 0 and setting the desired pressure
is the quickest way to accomplish this.
Trigger 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 in
a color change equipped system. The valve
corresponds to the color selected for the current
preset.
4. When fluid stops flowing out of the gun, release
the trigger. At this point, the Merkur AA fluid
pump will keep cycling until the Set Empty button
is pushed. Press the Set Empty button. The
stored mV value also displays next to the button.
The system returns to Standby mode.
Press the Set Empty button as soon as fluid
stops flowing out of the gun to prevent the
Merkur AA fluid pump from running while
empty.
