Calibrate Solution Pump

The SprayStar system will automatically calibrate itself in order to provide an optimal control for a particular situation.

NOTE: Do not perform this procedure for erratic solution pump rate or pressure if the A and B numbers are within range. If A and B numbers are within range, see entries for erratic rate or pressure in Troubleshooting section.

The only time auto calibration needed is when the A and B values do not lie within their ranges or when one of the following has been replaced:

• Solution pump/hydraulic motor assembly
• Proportional valve
• Hydraulic pump
• Spray Rate Controller

NOTE: The A and B ranges are:

Standard Flow Pump
	Speed (rpm)	Current (mA)
A	800-1400	350-650
B	5500-6000	1275-1625

High Flow Pump
	Speed (rpm)	Current (mA)
A	800-1200	400-600
B	4000-4500	1450-1750

To auto calibrate the sprayer:

NOTE: Solution pump switch should be turned off to perform this procedure.
