The calibration screen allows the operator to activate one spray head at a time and calibrate individual spray heads. Activate the WDS pump. Once the water is activated, push the accelerator to the floor to achieve the target speed of 2000 rpm. Once the target speed is met, the light will turn green. Water pressure should automatically settle to a pressure of 551 kPa (80 psi) if the system is working correctly. The light will turn green. Select an individual spray head by pressing corresponding function key (F) below the head being calibrated.
When calibrating an individual spray head, adjust the head intensity until hydraulic pressure target light is solid green. If hydraulic pressure is low, increase the head intensity by pressing up arrow. If hydraulic pressure is high, decrease the head intensity value by pressing the down arrow. After adjusting the value for head intensity, press the "OK" button to accept the change. Check hydraulic pressure. If pressure is within 50 psi of the target pressure, the light will turn green. Continue adjusting head intensity until the light maintains green status a majority of the time.
