DETAILS OF OPERATION
HEIGHT UP AND DOWN
Figure 4-1 Lift Column/Cylinders
Hydraulically, the three lift stages are driven in
parallel but will move in series due to the
increase in pressure associated with lifting each
successive stage.
TILT LEFT AND RIGHT
BERCHTOLD recommends that the tilt
cylinders not be replaced by the end user
because of the risk of contamination entering the
hydraulic system.
Tilt right and tilt left movements are
independent of any other function.
Tilt right is achieved by solenoid Y12 retracting
the tilt cylinder. This pulls the right side of the
table down.
Tilt left is achieved by solenoid Y11 extending
the tilt cylinder. This pushes the right side of the
table up.

TRENDELENBURG AND REVERSE
TRENDELENBURG
Trendelenburg and reverse Trendelenburg are
independent of any other column function with
the exception of limitations listed in Table 2-2.
There is a single Trendelenburg cylinder on the
foot side of the column.
Trendelenburg is activated via solenoid Y21.
Reverse Trendelenburg is activated via solenoid
Y22.
BERCHTOLD recommends that the
Trendelenburg cylinder not be replaced by the
end user because of the risk of contamination
entering the hydraulic system.
TABLE TOP HYDRAULICS
The table top hydraulics consist of the table top
distribution blocks, back, leg, and kidney
cylinders.
The pressure and tank lines for the top column
manifold are shrouded by the column covers.
