SECTION II
TESTING AND TROUBLESHOOTING
2.1 Operational Test
In order to effectively diagnose malfunctions of the 7300
Modular Surgical Table, it may be necessary to perform
an operational test as follows:
DANGER
Refer to the Operator Manual for
complete instructions on operating the
surgical table. Failure to do so could result in
personal injury.
Power must be supplied to the unit to measure
the voltage at the Test Points. Do not touch any
bare wires or terminals while making these
voltage checks. Failure to do so may result in
electrical shock which could result in serious
personal injury or death.
NOTE
The Operational Test, for the most part, only de-
scribes what should happen when the surgical table is
operated. If the surgical table does something other
than described, a problem has been discovered.
Refer to the Troubleshooting Guide to determine the
cause of the problem and its correction.
(1) Plug power cord into table's plug receptacle.
See Figure 2-1, Sheets 1 and 2.
(2) Observe. The line power pilot lamp should
illuminate.
(3) Unplug the power cord.
(4) Press ENABLE button on hand control.
(5) Observe. The hand control display should
illuminate and display the current table position
and battery charge level (XX POSITION and
BATT LEVEL XX. After 10 seconds, the hand
control display should extinguish.
(6) Press and hold UNLOCK & ENABLE buttons on
hand control for three seconds.
(7) Observe. The motor pump should run and the
table should lower (floor lock cylinders should
retract) until table is on its casters. The hand
control display should read UNLOCKING
FLOOR and then ON WHEELS.
SECTION II
TESTING AND TROUBLESHOOTING
(8) Move the surgery table around.
(9) Observe. The casters should swivel freely and
the table should roll easily on the casters. The
table should not wobble.
(10) Press ENABLE button on hand control.
(11) Observe. The motor pump should run and the
main floor lock cylinders should extend. After
eight seconds, the motor pump should stop
running. Then the motor pump should begin
running again and the outrigger floor lock
cylinders should extend. After six seconds, the
motor pump should stop running. The hand
control display should read LOCKING FLOOR
while the floor lock cylinders are extending.
(12) Insert pins of Head Section into sockets on
column end of table. Rotate latch handles to
locked position (to move latch handles to locked
position, rotate them away from you) and then
pull and push on head sections.
(13) Observe. When the latch handles are rotated to
the locked position, the section being installed
should now be held securely in place. No side-
to-side or in-and-out movement should be
possible.
(14) Press the ENABLE and REVERSE POSITION
buttons on hand control.
(15) Observe. The hand control display should read
REVERSE POSITION.
(16) Press the FLEX button and then REFLEX
button.
(17) Observe. Hand control display should indicate
these positions are "disabled" and cannot be
used when table is in REVERSE POSITION.
(18) Press the ENABLE and NORMAL POSITION
buttons on hand control.
(19) Observe. The hand control display should read
NORMAL POSITION.
