NOTE:
Anytime a sensor, pressure control assembly or both are replaced,
the these calibrations must be performed.
1. ZERO CALIBRATION
1.
Place prime/pressure relief valve in the prime (open) position.
2.
Set the pressure control knob to the minimum setting (CCW).
3.
Detach the pressure control assembly.
4.
Place the jumper (PN 117-207) on both prongs of the "P-ZR" terminal. Note: This jumper comes with a new
Pressure Control Assemblyand is installed on the "P-ZR" terminal. If you are "Zero Calibrating" a Pressure
Control Assembly presently in the unit, remove the jumper from one prong of the "P-ZR" terminal and place
on both prongs of the "P-ZR".
5.
Turn machine "ON" and ensure it is not cycling.
6.
If the yellow light on the electrical board is on, use an insulated screwdriver to turn the "LCD ZERO" trim
pot (P501) counter-clockwise until the light goes out. Then turn it clockwise until the light just comes back
on. At this point, the "Zero" Calibration is complete.
7.
If the yellow light is OFF, turn the "Zero" trimpot clockwise, just until the light comes on and stop.
At this point "Zero" Calibration is complete.
NOTE: If your machine is equipt with the optional LCD, as a double check to confirm that the pump is at
true zero the LCD should read "0000" when the yellow light just comes on.
NOTE: If the yellow light remains constantly "ON", or "OFF" during this calibration, the sensor is defective
and should be replaced.
8.
When calibration is complete, move jumper from both prongs of the "P-ZR" terminal to single prong of the
"P-ZR" Terminal.
2. PRESSURE CALIBRATION
1.
Attach a 50', 1/4" airless hose, airless gun with 0.017 tip and a 5000 psi pressure gauge to the pump.
2.
Place the suction tube into a bucket of Coro-chek and water.
3.
Turn prime/pressure relief valve to the prime (open) position.
4.
Complete the ZERO calibration, as per "ZERO CALIBRATION".
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 glycerine gauge (not the LCD) , slowly adjust the Pressure Trimpot (P502) (clock-
wise to increase and counter-clockwise to decrease) until the maximum static pressure is 3300 psi, with
the pressure control knob fully clockwise. Trigger the gun several times to ensure pressure returns to
3300 psi .
3.
LIQUID CRYSTAL DISPLAY CALIBRATION -
(If so equipped)
1.
Complete the "ZERO CALIBRATION" and "PRESSURE CALIBRATION" procedures prior to commencing
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 LCD Set trimpot (P503). Turn Trimpot CCW until it clicks. Then
adjust to match pressure against pressure gauge reading.
4.
Move the pressure control knob to different settings and trigger the gun several times to ensure that the
LCD continues to match the pressure gauge reading.
5.
Reattach Pressure Control Assembly.
