THE MATERIAL-FEED SYSTEM (CONTINUED)
DESCRIPTION OF VALVE SECTIONS (CONTINUED)
B. FLOOR (DRAG CONVEYOR)/FEED ROLL
The left valve section controls the floor and feed roll speed. It is an electrically-driven proportional
valve that is controlled by the floor increase (
FLOOR INC
) and floor decrease
(FLOOR DEC)
buttons on the keypad of the main control panel and the toggle switch on the radio remote
trasnmitter. Pressing the buttons or toggling the switch up or down varies the input voltage to
the solenoid and moves the spool in the valve accordingly, allowing more or less oil flow to
the floor and feed roll. There is a pressure switch on the forward circuit that is set for 1,500 psi
(10,342 kPa) that triggers the auto-reverse function on the floor.
C. HOSE REEL
The middle section of the manifold controls the hose reel. The flow rate is factory-set so that the
hose reel winds at a rate of about 12 RPM.
