assembly (board) and is installed on the "P-ZR" terminals. If you are "Zero Calibrating" a pressure control assembly presently in the unit, remove jumper from single terminal P-ZR and place on both terminals P-ZR. When Zero Calibration is complete, replace jumper on a single terminal of P-ZR.

5.Turn machine "ON" and ensure it is not cycling.

6.If the yellow zero light on the electrical board is ON, use an insulated screwdriver to turn the "ZERO" trimpot counterclockwise until the light goes out. Then turn it clockwise until the light just comes back on. If so equipped, look at the LCD Display and if "0000" is showing the Zero Calibration is complete. If the display shows more than "0000", turn the Zero Trimpot CCW until "0000" is showing. If "-- -- --" is showing, turn the zero trimpot CW until "0000" is displayed.

7.If the yellow light is OFF, turn the "Zero" trimpot clockwise, just until the light comes on and stop.

Confirm "0000" is displayed.

NOTE: If the yellow light remains constantly "ON" or "OFF" during this calibration, the sensor is defective and should be replaced.

8.IMPORTANT: When calibration is complete, move jumper from both "PZ-R" terminals to single terminal on P-ZR.

PRESSURE CALIBRATION

1.Complete the ZERO calibration, as per "ZERO CALIBRATION" prior to commencing this calibration.

2.Attach a 50', 1/4" airless hose, airless gun with 0.017 tip and a

5000 psi glycerin filled pressure gauge to the pump.

3.Place the suction tube into a bucket of Coro-chek and water.

4.Turn Prime/Pressure Relief Valve to the prime (open) position.

5.Turn Pressure Control Knob clockwise until machine starts to prime.

6.Place the Prime/Pressure Relief Valve in the pressure (closed) position.

7.While watching pressure gauge, slowly adjust the pressure trimpot (clockwise to increase and counterclockwise to decrease) until the maximum static pressure is 3000 psi, with the pressure control knob fully clockwise. Trigger the gun into pail several times to ensure pressure returns to 3000 psi.

LIQUID CRYSTAL DISPLAY (LCD) CALIBRATION

NOTE: Your unit may or may not be equipped with an LCD.

1.Complete the "ZERO CALIBRATION" and "PRESSURE CALIBRATION" procedures prior to starting this calibration.

2.Turn Pressure Control Knob up until system pressure is above 2500 psi (as indicated on glycerin filled pressure gauge) and the machine is not cycling.

3.Use an insulated screwdriver to adjust the Set trimpot. Turn trimpot counterclockwise until it clicks, and then adjust to match pressure against pressure gauge reading.

4.Move the pressure control knob to different settings and trigger the gun several times into pail. This will ensure that the LCD continues to match the pressure gauge reading.

PHASE LIMIT TRIMPOT CALIBRATION (formerly known as the Low Voltage or Master Voltage Calibration)

1.Attach a 50', 1/4" airless hose, airless gun with .017 tip and a 5000 psi glycerin filled pressure gauge to the pump.

2.Place the suction tube into a bucket of Pump Conditioner and water.

3.Turn pump ON and turn up Pressure Control until the machine starts to prime.

4.Place the Prime/Pressure Relief Valve in the pressure (closed) position.

5.Pressurize pump to 600 psi.

6.Trigger the gun several times noting the deadband (the amount of pressure drop before the pump rebuilds to set pressure).

7.If deadband is greater than 100 psi, adjust the low pressure voltage trimpot so that the deadband is less than 100 psi and the pressure increase after the gun trigger is released is less than 200 psi.

These pressures are guidelines and may vary slightly from pump to pump.

8.Reattach Pressure Control Assembly being careful not to pinch wires.

NOTE: The 331-315-99 Pressure Control Assembly has a reddish brown terminal labelled “Inhibit Switch.” At all times there should be a jumper on the two left terminals, which are the closest to the “S2” connection. Also on the Revision E is a terminal labelled “ON- SL.” This terminal should never have a jumper on it.

ELECTRICAL TROUBLESHOOTING

A variety of causes can lead to problems with your sprayer’s electrical system. Sometimes, it will not start. See page 15 for a list of possible problems and solutions to fix them.
