Hopper Switch
The hopper switch is used to raise or lower the hopper
by energizing solenoids S1 (hopper up) or S4 (hopper
down). This switch is located in the control box enclo-
sure (Fig. 4).
When the hopper switch is pushed to raise the hopper,
the demand solenoid (S2) and the hopper up solenoid
(S1) are energized. These energized solenoids allow
hydraulic flow to extend the lift cylinder and raise the
hopper. Additionally, the brush relay is energized which
ensures that the sweeper brush will not be rotating.

When the hopper switch is pushed to lower, the hopper
down solenoid (S4) is energized allowing the raised
hopper to contract the lift cylinder. The hopper down
proximity switch prevents the sweeper brush from rotat-
ing until the hopper is fully lowered.

The hopper switch terminals are marked as shown in
Figure 5. The circuitry of this switch is shown in the chart
below. With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
switch position. Verify continuity between switch termi-
nals.
