Description of the side scrub brush pressure settings (Using the dual proportional valve driver):
The dual controller uses an “A” prefix for the optional side brush settings and a “B” prefix for the Main
brush settings.
AP1 – The low side brush floor pressure setting.
AP2 – The medium side brush floor pressure setting
AP3 – The high side brush floor pressure setting
AP4 – The P4 setting is not used. (Any number input will have no effect.)
AJ9 – Jog. This is used to simulate a AP1 – AP3 setting and its effect on the side brush pressure in real
time. (This does not require an input setting.)
AUP - The ramp time required for the output signal to increase by 1 amp.
Adn - The ramp time required for the output signal to decrease by 1 amp.
dF – Dither frequency. (Dither is an oscillation feature that eliminates slip stick in the operation of the
solenoid.)
di – Display orientation
SA – Save settings
DUAL CONTROLLER “A” (SIDE SCRUB BRUSH) SETTINGS:
Turning the right control knob scrolls through the parameters listed above.
Turning the left control knob changes the settings of each parameter.
The settings are saved by turning the right control knob to SA and rotating the left control knob one full
turn (in either direction).
To turn on the controller first turn on the ignition key but do not start the engine.
Note: in the next step stay clear of the scrub head as the sub head will lower to the floor.
Turn on the scrub head switch and the green switch.
