F. Underside Components
Located on the underside of the machine are the
following components:
DRIVE SHAFT:
Located toward the center of the underside
is the lane drive shaft. This shaft is driven by the
drive motor. The squeegee assembly is also mounted to,
and pivots on, this drive shaft.
TACH SENSOR:
Mounted to the left side plate is the TACH
sensor. A ten-tooth timing sprocket is rotated as the
drive shaft turns. As the teeth of the sprocket pass
through this sensor pulses are sent to the PC. The PC
counts these pulses and calculates the IPS (INCHES PER
SECOND) travel speed of the machine. This is used to set
the 7 different speeds of the machine. It is also used
in the program to sense if the drive wheels are slipping.
The PC compares the rate of pulses coming from the tach
sensor to the rate of pulses coming from the LANE
DISTANCE SENSOR.
DRIVE WHEELS:
Mounted on the lane drive shaft are the two
drive wheels. These wheels are powered by the drive
motor and drive the machine on the lane.
SQUEEGEE ASSEMBLY:
Mounted to the drive shaft is the
squeegee assembly. This assembly vacuums the cleaner and
oil off of the lane during lane cleaning.
EMI FILTER:
(On 230 Volt Machines Only) The electrical
circuits of the machine are filtered to reduce line
conducted and radiated emissions. This filter must be
connected properly to ensure compliance with
Electromagnetic Compatibility Directives (CE Mark).
