Dust Control/DustGuard
™
Systems 86 Service Manual – CS7000
Circuit Description
The following conditions must be met for the DustGuard™ system to operate:
• The DustGuard™ system must be installed in the configuration menu.
• 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 (battery machines) or jumpered (Diesel and LPG machines).
• The
400-amp Fuse F1
must be closed to provide positive voltage from the
Battery
to the load side of
Auxiliary
Contactor K9
, and to the 10-amp circuit breaker
CB5
.
• 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 J7-12
.
• The
Auxiliary Contactor K9
must be closed to provide positive voltage to circuit breaker
VACC2/CB2
.
• Circuit breaker
VACC1/CB1
must closed to provide positive voltage to the
Dust Control Motor Contactor K6
coil and the
Shaker Motor M14
.
• The
J2-6 Output
provides the negative ground to the
Dust Control Motor Contactor K6
coil under the
following conditions:
– If the hopper is down:
◦ The
A1 Main Machine Controller
must receive a signal from the
A3 Control Panel
via the
CAN BUS
that
the operator has pressed the DustGuard™ spray switch (blue LED on).
◦ 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 backward.
– If the hopper is up, the
A1 Main Machine Controller
must receive a signal from the
A3 Control Panel
via
the
CAN BUS
that the operator has pressed the DustGuard™ spray switch. Note that the seat switch
does not have to be closed.
• Circuit breaker
CB5
must closed to provide positive voltage to the load side of
Dust Control Motor Contactor
K6
.
•
Dust Control Motor Contactor K6
must be closed to provide positive voltage to the
Dust Control Motor M5
.
•
Dust Control Motor M5
must be connected to battery ground.
• Circuit breaker
VACC2/CB2
must closed to provide positive voltage to the
DustGuard Valve L2
and the
DustGuard Pump M22
.
• The
J3-13 Output
provides the negative ground to the
DustGuard Valve L2
and the
DustGuard Pump M22
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 DustGuard™ spray switch (blue LED on).
