3. Run the Sweep through several cycles, and verify it is stopping at the desired position.
A slight amount of overtravel is normal. If the
Sweep runs considerably past the Home
position and consistently stops at the same
point, reset the home disc with the Sweep at a
slightly lower position. Excessive coasting of
the Sweep past the Home position could
indicate a motor brake problem. You can
observe the operation of the brake by
watching the motor shaft and hexagonal hub
in the center of the brake. The shaft should
stop abruptly when the motor turns off.
4.2.3.4 1
st
and 2
nd
Guard Positions
When the ball detector senses the passage of a ball, the Chassis directs the Sweep to descend to
the 1
st
Guard position so that no further play can take place while the pins complete their action
and are scored. Following removal of the deadwood, the Sweep stops at the 2
nd
Guard position
while pins are spotted or respotted. At both the 1
st
and 2
nd
Guard positions, the Sweep should be
positioned slightly above the surface of the lane. These positions are indicated on the Chassis
display in degrees of drive shaft rotation (000 to 360). The 1
st
Guard position should be
approximately 66 and the 2
nd
Guard position should be approximately 270.
Hold this lever down to
disengage brake.
