90 - Options and Accessories
The SC900 machine may be equipped with optional accessories depending on the needs of the owner. Some
of these accessories don’t directly impact servicing the machine, but some may. So it is good to know what
accessories you may encounter and how they impact the machine.
Onboard Charger
The onboard battery charger is located in front of the battery bay. The charger connects directly to the
batteries. It also adds (replaces) an interlock wire to the main key switch to prevent machine activation
when the batteries are being charged.
When the charger is not present, a red battery-positive wire is connected to the input of the 2.5-amp circuit
breaker. When the charger is present, this wire is replaced with the green interlock wire from the charger.
When the charger is plugged in, this wire has no power, and therefore, the machine is inoperable.
Refer to the “24 - Electrical System” on page 28 for additional information on the charger.
TrackClean
The TrackClean module adds a telemetry module at the front-
left of the battery bay. This module receives discrete inputs
from various circuits in the machine and reports them via
cellular network to the machine’s administrator. The module
also receives GPS information for the machine’s location and
reports this as well.
The TrackClean module may also incorporate a Smartkey
reader, located on the solution control panel. If this option is
present, the machine will be inoperable without an authorized
Smartkey.
EcoFlex
The EcoFlex option adds a detergent control board behind the operator’s handle, and also a detergent system
with pump in the battery bay. Refer to the “30 - Solution System” on page 43 for additional details.
Battery Watering
Adds a watering manifold and ll valves to the battery ll caps. It also includes a removable hand pump. It
is not covered by the service manual.
