SECTION II
TESTING AND TROUBLESHOOTING
(22) Press the ENABLE button and then press the
LEVEL button until the table reaches its level
position. Using a protractor, check the table top
to ensure it is level within ±2°.
(23) Observe. The table top should move to a level
position within ±2° as follows: The lateral tilt
function should level out first; then a sequence
of the Seat, and Trendelenburg functions should
move, with each function moving no more than
10° at a time.
(24) Squeeze the release handle on the head section
and move the head section thru its full range of
motion.
(25) The head section should move smoothly and
should not take excessive force. The head
section should meet the following range of
motion specifications:
Head Section:
Mounted on Head End ........... +30° (±3°) to -30° (±3°)
Mounted on Foot End ............ +30° (±3°) to -75° (±5°)
(26) Move head section to level position and then
place approximately 40 lbs. (18 kgs) at Point C
(head section). Observe head section for two to
three minutes.
(27) Observe. The head section should not drift.
(28) Place approximately 400 lbs. (181.4 kg) of
weight on table top as follows: 28 lbs. (12.7 kg)
at Point C (head section), 152 lbs. (69 kg) at
Point B (back section), and 168 lbs. (76.2 kg) at
Point A (seat section).
(29) Press ENABLE button and then press TABLE
UP and TABLE DOWN buttons to run column
function up and down several times.
(30) Observe. Column function should move up and
down steadily and smoothly. No binding
condition should be evident, especially when
column is lowering. There should be no exces-
sive side-to-side play in column assembly.
(31) Remove weight from table top.
(32) Press and hold the SYSTEM OVERRIDE button
while pressing the function buttons, one at a
time, on the emergency override panel.
(33) Observe. Each function should move as
depicted by the illustration on its button.
(34) Press each function button on the foot control.
Then place the table top in REVERSE position.
Then press each function button on the foot
control again.
(35) Each function should move as depicted when
table top is in NORMAL position. The table
should not operate, using the foot control, when
the table top is in REVERSE position.
(36) Plug power cord into table's power receptacle.
DANGER
Electrical power must be connected to
perform the following steps. Do not
touch any bare wires or terminals. Failure to do
so could cause an electrical shock which could
result in serious personal injury or death.
(37) See Figure 2-2 for this step. Check for 32.5
VAC ± 2 VAC across Test Points C and D and
across Test Points D and E.
(38) Observe. There should be 32.5 VAC ±2 VAC
across
both
sets of test points.
(39) See Figure 2-2 for this step. Check for 27.7
VAC ± 2 VAC across Test Points F and G and
across Test Points H and J. Check for 27.8
VAC ±2 VAC across Test Points K and L.
(40) Observe. The proper voltages should be
present across
each
set of test points.
