counts. The tach counter value will increase or decrease by 100 counts,
accordingly. When the ball nut assembly reaches the top or bottom of
the tower, the corresponding limit will change from 0 to 1. If the cyl-
inder was refilled using the REFILL button, it may require multiple
presses of the 'UP 100' softkey before the 'Lower limit' indicator
changes to 0. When the Lower limit indicator is 1, pressing the DOWN
100 softkey will have no effect. Similarly, when the Upper limit is 1,
pressing the Up 100 softkey (B) will have no effect.
If the rear tower cover plate is removed to expose the sensors, as
shown above in Figure 9-3, you can simply interrupt the sensors with
a slip of paper, rather than using the flag.
If either sensor fails, the sensor harness must be replaced.
