2. Loosen the two bolts, shown in Figure 4- 277,
securing the waste tank guard and vacuum motor
bracket in place. Only loosen the bolts enough to
allow the vacuum motor bracket to move.
3. With the two bolts loosened, place the waste tank
into the waste tank guard assembly.
4. Move the vacuum motor and bracket assembly to
a position where the seal is compressed by the
waste tank.
5. While holding the vacuum motor and bracket, remove the waste tank and tighten the
two bolts.
6. After securing the motor and bracket in place, remove and reinsert the waste tank
into the guard assembly several times. The waste tank should compress the seal
enough to ensure a leak free connection. At the same time, the seal should not be
pulled off the vacuum motor or abraded when removing or reinserting the waste
tank.
7. When adjustments are complete, reinstall the hood, cleaner tank cap, waste tank,
and vacuum hose.
4.3.7 Adjusting the Optical Sensor
The optical sensor
’s factory settings should be sufficient for the majority of centers. If the
sensor ever needs to be replaced, the behavior of the machine at the end of the lane is
erratic, or the center uses an anti-idling plate mounted on the rear of the pindeck, the
sensor will need to be adjusted. Unlike all other adjustments, it is necessary to have the
Phoenix LT4 powered while adjusting the optical sensor. The two adjustments to the optical
sensor are D-L and the sensitivity as shown in Figure 4- 29. The D-L refers to dark
detection (normally closed) or light detection (normally open). Sensitivity controls how easy
the sensor is to trigger.
Perform the procedure below with the machine powered and in the
operating
position.
1. Position the machine with the sensor overtop of the lane.
