Slide & Height Sensor
Figure 5-2 Height Sensor
The slide and height sensors are DC
potentiometer s (10k Ω voltage divider) with an
output signal from 0 to 5 VDC. The height
sensor has a longer sensor cable than slide.
Figure 5-3 Slide Sensor
Software senses readings from 0.5 (at extreme
forward slide) to 4.5 VDC (at extreme reverse
slide). A reading of 1.5 VDC is nominal when
the table top is centered over the column.
Auxiliary Pendant Switch
Figure 5-4 Auxiliary Pendant Switch
The auxiliary pendant switch is a limit switch.
When it senses that the foot pump handle is
pulled out, it signals the CPU to provide power
to the auxiliary pendant and turn off the primary
hand pendant. The auxiliary pendant switch is
located inside the base.
