Sweep System, Main 380 Service Manual – CS7000
Circuit Description
The Following Conditions Must be Met for the Main Sweep System To Operate
• The
Hopper Interlock Switch S3
must be closed.
• There must be positive voltage to the
J7-1 Interlock Input
. For this to happen:
– The
Seat Switch S9
must be closed.
– The
Safety Relay K14
on the
Steer By Wire Controller A5
must energize the coil to close the
Safety Relay
K14
contactor.
– The
Emergency Stop Switch S15
must be closed.
– The
Battery Interlock S13
must be closed.
• The
400-amp Fuse F1
must be closed to provide positive voltage from the
Battery
to the load side of
Auxiliary
Contactor K9
.
• The
Ignition Switch S14
must be closed to provide positive voltage to the
Auxiliary Contactor K9
coil. The
J2-14 Output
on the
A1 Main Machine Controller
provides ground to the
Auxiliary Contactor K9
coil when the
Ignition Switch S14
provides an input to the
Key Switch Input J7-13
.
• The
Auxiliary Contactor K9
must be closed to provide positive voltage to circuit breaker
VACC1/CB1
.
• Circuit breaker
VACC1/CB1
must be closed to provide positive voltage to the
Broom Motor Contactor K4
.
• The
J2-16 Output
on the
A1 Main Machine Controller
must provide a ground to the
Broom Motor Contactor K4
coil.
J2-16
provides ground to
K4
under the following conditions:
– The
A1 Main Machine Controller
must receive a signal from the
A3 Control Panel
via the
CAN BUS
that the
operator has pressed the sweep switch.
– The
A1 Main Machine Controller
must receive a signal from the
A2 Drive Controller
via the
CAN BUS
that
the machine is moving forward or reverse.
• The
150-amp Fuse F2
must be closed to provide positive voltage from the
Battery
to the load side of the
Broom Motor Contactor K4
,
• The
Broom Motor M1
must have connections to battery ground
B-
.
Main Broom Actuator Motor
The
J3-3
and
J2-4 PWM Outputs
from the A1 Main Machine Controller provide voltage to the
Main Broom
Actuator Motor M21
. The output polarity determines whether the
Main Broom Actuator Motor
lowers or raises
the scrub deck.
The resistance through the main broom actuator potentiometer
R4
varies with the broom height. The
J7-33
POT HIGH
pin sends a fixed positive voltage to
R4
with
J7-35 POT LOW
as a ground. The A1 Main Machine
Controller reads the voltage through
R4
from
J7-34 WIPER
to determine the broom height.
