34Service Manual – SC901 24 - Electrical System
On the operator’s handle is a combination battery indicator and hour meter. The
hour meter increments whenever the scrub system is active. The LED bar graph
on the battery indicator represents the battery charge.
The hour meter (battery indicator) also serves as a low-voltage cutout for the
scrub system. When the battery voltage is above the cutout threshold, the hour
meter grounds its FET (Field Effect Transistor) Drain output, which permits the
K1 relay to be energized (when the key switch is on). When the battery voltage
drops below this threshold, the FET opens, and the K1 relay is disabled.
The electrical box contains the majority of the
machine’s electrical controls.
• The K1 relay, located on the front wall,
serves as a “Scrub Enable” when the key
switch is on and the battery voltage is above
the cutout threshold (via the hour meter).
• The K2 relay controls the two brush motors,
but rst passes through the two 25 amp
circuit breakers. The K2 relay is enabled
only when the drive controller activates the
“Brake Release” output, and is active only if
the brush switch (deck lower lever) is closed.
• The K3 relay controls the vacuum motor,
but rst passes through the 20 amp circuit
breaker. The relay is active whenever the
keyswitch is on and the vacuum switch
(squeegee lower handle) is closed.
• When the optional TrackClean module is not present, a jumper is installed at the TrackClean electrical
connector. This jumper is required for machine operation, and is a series connection of the key switch.
The purpose of the circuit is so that a TrackClean module with a SmartKey reader can disable the
operation of the machine if no authorized SmartKey is present.
When the scrub deck is raised, all scrub related functions
are disabled when the Brush Switch is opened. This switch
is using the normally closed contacts, and the switch opens
when the deck lift handle is moved to the raised and locked
position.
When the optional on-board battery charger is present, the
battery-side of the key switch is replaced with an interlock
circuit from the charger. (Power to the 2.5A circuit breaker
comes through the charger.) This interlock feature allows
the charger to disable all control of the machine when the
charger is plugged into a wall outlet and the battery is
being charged. The charger doesn’t disable all power to the
machine; just the control power.
The charger contains a normally-closed relay. When the charger isn’t plugged in to facility power, the relay
is closed, and the key switch circuit is enabled. When the charger is plugged in, the relay opens, and the key
switch circuit is disabled.
