Tilt sensor calibration
:
NOTE:
Use a bubble level resting on the tabletop as a level gauge. The level sensor
adjustment screws are accessed from the top of the unit. A two degree maximum dead-
band exists for each axis. For return to level to function, the tabletop must be outside of
this dead-band.
1. Turn power switch on. The green light illuminates.
2. Press and hold DOWN TO LOCK button until green LOCKED WHEN LIT indicator
illuminates.
3. Raise the tabletop to a comfortable level.
4. Push the LEFT LATERAL ROLL or RIGHT LATERAL ROLL buttons to level
tabletop.
5. Push the LEFT LATERAL ROLL button to tilt the tabletop more than five degrees.
6. Push the RETURN TO LEVEL button to level the tabletop; note the degree of level.
7. Push the RIGHT LATERAL ROLL button to tilt the tabletop more than five degrees.
8. Push and hold the RETURN TO LEVEL button to level the tabletop; note the degree
of level.
9. Turn the tilt adjust screw a partial turn.
NOTE:
Clockwise will stop the tabletop more to the right, counter-clockwise will stop the
tabletop more to the left. The tabletop will overshoot each stopping point, requiring
"splitting the difference" to adjust for proper balance.
10. Test the adjustment by:
a. Push the LEFT LATERAL ROLL button to tilt the tabletop to maximum.
b. Push the RETURN TO LEVEL button to level the tabletop; note the degree of
level.
c. Push the RIGHT LATERAL ROLL button to tilt the tabletop to maximum.
d. Push the RETURN TO LEVEL button to level the tabletop; note the degree of
level.
11. Continue adjustments until the tabletop stops from either maximum lateral roll at the
same offset from zero.
12. Trendelenburg / reverse-trendelenburg calibration (TREN/REV.TREN).
a. Repeat steps of left and right lateral roll calibration using TREN/REV.TREN
buttons on the hand pendant.
13. Turn power switch off. Wait 30 seconds for discharge, then unplug power cord from
wall outlet.
14. Disconnect red wire from battery A positive terminal.
15. Attach left tilt cover.
