ADJUSTMENTS & PROCEDURES
NAULTILUS SCRUB BRUSH FLOOR PRESSURE ADJUSTMENT
Setting the scrub brush floor pressure controller (proportional valve driver)
The floor brush pressure controller (located on the left front face of the operator console) provides three separate brush floor pressure forces by
controlling the hydraulic pressure output of the proportional reduction valve located on the main hydraulic manifold at port 6.1.
This variable output pressure is applied to the rod-end of the scrub head lift cylinder. This variable pressure is balanced against the steady 450 psi
provided by the reduction valve (above) to achieve the desired 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 adjustable parameters:
P1 – The low brush floor pressure setting.
P2 – The medium brush floor pressure setting
P3 – The high brush floor pressure setting
P4 – The P4 setting is not used. (Any number input will have no effect.)
J9 – Jog. This is used to simulate a P1 – P3 setting and its effect on the brush pressure in real time. (This does not require an input setting.)
UP - The ramp time required for the output signal to increase by 1 amp.
dn - 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
