ELECTRICAL SYSTEM
ELECTRICAL SYSTEM
The electrical system on the 2023 was designed with simplicity being a core quality. In de-
signing the system this way it is not complicated by a computer and is very basic to repair.
All the circuits are controlled by either switches, relays or a combination of the two. The
circuits are protected by push to reset circuit breakers located on the rear of the control
panel. The battery gauge and the brush pressure meter are both analog gauges and all
status lights are simple 24 volt indicator bulbs.
SWITCHES
The switches we use all have a similar face but are configured differently internally.
RELAYS
The early machines used Cole Hersee contactor type relays (silver can style) and the later
machines use Bosch relays (black plastic boxes).
MOTORS
The motors that are used through out the machine are designed to be very durable and
give long service life. The brush deck motor is a permanent magnet gear reduction type to
give large amounts of power for scrubbing. The vacuum motor is a very high speed motor
that develops vacuum for the recovery system.
ACTUATORS
The 2023 uses only one actuator for the brush head. This is a heavy duty 500 lb. actuator
that has internal limit switches.
WIRING
The wiring on the machine is numbered for easy circuit determination and to be easy to
trace. We over size our wiring to eliminate failures and for safety reasons.
