not turn on and no motion should occur. Repeat for
REVERSE TRENDELENBURG.
2. With switch released, actuate same functions. When
motion has started, depress switch. The pump
should turn off and motion should stop.
3. Starting with tabletop horizontal, actuate BACK
RAISE at least 10° to ensure articulation actuates seat
limit switch. Actuate REVERSE TRENDELENBURG
until motion stops. Ensure seat limit switch LS3
actually stopped motion by actuating REVERSE
TRENDELENBURG with override control switches
located on shroud cap. Seat section should move
farther down by a small amount.
4. If limit switch LS3 does not function as described
above, verify it is being actuated when seat section
is within 0.5 ± 0.3° of its mechanical stop (use
REVERSE TRENDELENBURG function). If limit
switch requires adjustment, proceed as follows:
a. Position tabletop at maximum RIGHT TILT for
access to limit switch. Remove P28 from control
board housing box.
NOTE: The shrouds have to be lowered but not
removed to gain access to P28.
b. Connect P28 to a voltmeter set to read
resistance.
c. Position tabletop so seat section is within 0.5 ±
0.3° of mechanical stop and check switch. If
switch is not made, adjust switch until it is
energized.
d. Using override switch, position tabletop to
mechanical stop in REVERSE TRENDELENBURG to
ensure switch does not get damaged.
e. Remove voltmeter and reinstall P28 into control
board housing box. Level tabletop and actuate
REVERSE TRENDELENBURG to verify LS3
stops table motion within 0.5 ± 0.3° of its
mechanical stop.
7.14 LS4 - BACK SECTION LIMIT SWITCH
ADJUSTMENT
NOTE: This Back Section Limit Switch (LS4) is not present
on newer tables.
1. With tabletop sections horizontal, manually
depress switch mounted to underside of back
section. Attempt to actuate FLEX. Pump should not
turn on and no motions should occur. Repeat for
TRENDELENBURG and BACK LOWER.
2. With switch released, actuate same functions. When
motion has started, depress switch. Pump should
turn off and motion should stop.
3. Starting with tabletop horizontal, actuate BACK
LOWER until motion stops. Verify motion stopped
from back limit switch by actuating BACK LOWER
with override control switches located on shroud
cap. Back section should move further down by a
small amount.
4. If limit switch LS4 does not function as described
above, ensure it is being actuated when back section
is within 0.5 ± 0.3° of its mechanical stop (use
TRENDELENBURG function). If limit switch
requires adjustment, proceed as follows:
a. Remove P29 from control board housing box
and connect it to a voltmeter set to read
resistance.
NOTE: The shrouds have to be lowered but not
removed to gain access to P29.
b. Position tabletop so table back section is within
0.5 ± 0.3° of its mechanical stop (use
TRENDELENBURG function). Tighten limit
switch locknut until voltmeter indicates switch
is made. If locknut adjustment range is not
adequate, install switch pushbutton extension
(P129360-679) using Loctite RC/609.
c. Using override switch position table to its
mechanical stop in TRENDELENBURG and
ensure switch did not get damaged.
d. Remove continuity tester and reinstall P29 into
control board housing box. Level tabletop and
actuate TRENDELENBURG function to ensure
LS4 stops table motion within 0.5 ± 0.3° of its
mechanical stop.
7.15 LS5 - COLUMN LIMIT SWITCH
ADJUSTMENT
1. Using override control switches, raise tabletop to
maximum height.
2. Lower tabletop approximately 1/16" (1.59 mm)
from maximum position.
3. Set LS5 height and depth so switch disengages
when roller on actuator connects with "V" slot.
4. Tighten switch mounting bracket screws.
5. Using hand control, actuate tabletop RAISE and
LOWER functions, checing to ensure LS5 stops table
motion 1/16 ± 1/32" (1.59 ± 0.79 mm) before
maximum table height.
