Setting the side scrub brush floor pressure (Using the dual proportional valve driver)
The dual floor brush pressure controller (located on the left front face of the operator console) provides three separate side brush
floor pressure forces by controlling the hydraulic pressure output of the proportional reduction valve located on the SSB hydraulic
manifold at port 6.2.
This variable output pressure is applied to the piston-end of the side scrub head lift cylinder. This variable pressure is balanced
against the steady 450 psi provided by the reduction valve (above) to achieve the desired side scrub brush floor pressure.
The controller has a left control knob, a right control knob, and an information screen.
The right control knob scrolls between the various setting titles.
The left control knob provides input settings.
Description of the side scrub brush adjustable parameters:
The dual controller uses an “A” prefix for the optional side brush settings and a “B” prefix for the Main brush settings.
BP1 through BP4 control the low, medium, and high main scrub brush floor pressure.
These along with BUP, Bdn, and dF parameters should be set using the information shown in the NAULTILUS SCRUB BRUSH FLOOR
PRESSURE ADJUSTMENT instructions.
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
The unit must be on to input settings.
Turning the right control knob scrolls through the parameters listed above.
Turning the left control knob changes the settings of each parameter.
