Sweep System, Side Broom 396 Service Manual – CS7000
Circuit Description
The Following Conditions Must be Met for the Side Broom 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
and circuit breaker
CB7
.
• 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
Side Broom Motor Contactor K8
coil.
• The
J2-15 Output
on the
A1 Main Machine Controller
must provide a ground to the
Side Broom Motor
Contactor K8
coil.
J2-15
provides ground to
K8
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 and side broom switches.
– 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.
• Circuit breaker
CB7
must be closed to provide positive voltage to the load side of
Side Broom Motor
Contactor K8
.
•
Side Broom Motor Contactor K8
must be closed to provide positive voltage to the
Side Broom Motors M8
and
M9
.
• The
Side Broom Motors M8
and
M9
must have connections to battery ground
B-
.
Side Broom Actuator Motor
The
J3-5
and
J3-17 Outputs
from the
A1 Main Machine Controller
provide voltage to the
Side Broom Actuator
Motor M13
. The output polarity determines whether the
Side Broom Actuator Motor
lowers or raises the side
brooms.
