Circuit Description
Vacuum Motors M5
and
M6
get positive voltage from the
Battery
when the load sides of contactors
K5
and
K1
are closed Contactors
K5
and
K1
close when the
A2 Control Board Assembly
connects the
K5
and
K1
contactor
coils to battery ground
Vacuum Motors M5
and
M6
are connected directly to battery ground
The
A2 Control Board Assembly
connects the
K5
and
K1
contactor coils to battery ground when:
•
The
A3 Switch/Display Panel Assembly
sends the
A2 Control Board Assembly
a signal via the CAN BUS that
the vacuum system has been switched on, or,
•
The
A1 Speed Controller
sends the
A2 Control Board Assembly
a signal that the wheel drive is switched on,
the scrub system is enabled and the vacuum system has not been switched off
Note:
The
A2 Control Board Assembly
monitors the voltage input from the
Vacuum Motor Shunt
wire connected to the ground side of
Vacuum Motors M5
and
M6
. If the voltage is out of the
acceptable range (.07 - .12 volts for a single vacuum motor or .15 - .24 volts for dual vacuum
motors), the
A2 Control Board Assembly
will sense that the float ball is sealed against the float
cage and that the recovery tank is full. The
A2 Control Board Assembly
will then shut down
the vacuum and scrub systems and display a recovery tank full icon on the LCD.
Component Locations
Vacuum Motor and Vacuum Hose
The
Vacuum Motor
sits in a cavity in the
Recovery Tank
To access the
Vacuum
Motor
, remove the five Phillips screws and
washers holding the top cover assembly
on the recovery tank and remove the top
cover assembly
Note that there is room in the
Recovery Tank
for an optional second
Vacuum Motor
The
Vacuum Hose
is clamped to the
outlet side of the
Vacuum Motor
and
exhausts the airflow from the
Vacuum
Motor
through to the underside of the
machine
