OPERATION TABLE
GENERAL
4.1 This Service Manual contains a technical
description and maintenance procedures for the RX600
Po wered Operation Table as shown in Fig. 1.
4.2 The table is a battery powered, mobile,
orthopaedic, and trauma table with two integral articulated
telescopic traction beams, which stow under the table-top
when not in use. The beams are e xtended for use, and are
used in conjunction with traction accessories. The tabletop comprises pre-traction leg supports, and head, hip, long
and short trunk sections.
4.3 The table can be used as a general purpose fivesection Operation Table, by fitting optional infill sections,
and an optional leg section, in place of the pre-traction leg
supports. The table design allows a full range of orthopaedic
and trauma surgical procedures to be carried out, including
pin and plate femur and tibia nailing, and arm traction.
4.4 The table is operated by electrical/electronic
circuits, which control the position of hydraulic cylinders
(via electro-hydraulic v alves) in response to signals from a
touch-button hand control, or from an optional foots witch.
The hand control and the footswitch both plug into
connectors at the top of the table column.
4.5 Power is provided by two 12V sealed lead-acid
batteries in the table base. The 12V batteries are connected
in series to give an output voltage of 24V. Trickle charging
for the batteries is provided by an inbuilt battery charger,
provision is also made for connection of an e xternal battery
charger for quick battery charging. Connection of the inbuilt
battery charger to the mains electrical supply is via a
removable cab le which plugs into the tab le base .
4.6 All table top trunk movements are electrically
controlled using either the hand control or, as an optional
accessory, the footswitch which is used by the surgeon
during cer tain procedures for height and Trendelenburg
control.
4.7 The main operation table sections are:
? Base.
? Central column.
? Head section.
? Long and Short trunk sections.
? Hip section.
? Sacral extension.
? Pre traction leg section.
? Traction accessories.
NOTE: Instruction and Service manuals should he readily
accessible for reference prior to, and when operating,
cleaning and servicing the table.
ELECTRICAL SYSTEM
NOTE: Electrical/electronic circuit diagrams are provided
at the end of this Manual in section 6.
Main control board
4.8 The main control board receives signals from the
hand control via an RS485 serial communication link. The
board also receives signals from the foots witch, table-base
cover s witches, levelling micros witches, level tilt s witch, opto
board, standby unit socket, door s witch, traction beam opto
sensors and table base on/off controls.
4.9 Outputs from the main control board pass to the
hand control via an RS485 serial communication link, to
the hydraulic solenoids via the top-of-column distributor and
solenoid boards, and to the base distributor board and FETRelay board for motor on/off control and motor direction
control. The main control board is supplied with 24V d.c.
from the batteries and generates its own 12V d.c. and 5V
d.c. supplies .
4.10 The principal functional areas of the main control
board are:
? Input buffering (pull-up and pull-down resistors and
capacitors).
? The microcontroller, which uses software to
implement table control functions.
? Output buffering (current drivers and le v el shifters).
? Motor direction drive and on/off control.
Height opto board
4.11 The height opto board is fitted at the base of the
column in a fixed position relative to the baseplate. It
responds to a metal reflector plate which moves up and
down with the column chassis and hence with the table
top. When the reflector mo ves in front of the three reflective
opto sensors (only two are used) electrical signals are
generated to signal to the main control board that the table
is at or above ‘minimum height’, or in the ‘castor’ position.
4.12 When the reflector plate is in front of reflective opto
coupler 01 and at the correct distance from it, a signal is
produced which passes via J1 on the opto board and the
10-way ribbon cable to J22 on the main control board.
4.13 When the reflector plate is in front of both reflective
opto couplers 01 and 03 signals from both pass to the main
control board which stops the table movement at the correct
position.
T-SM14g 7/44
4. INTRODUCTION
Base distribution board
4.14 This board receives signals from the main control
board for the height (e xtend) solenoid, the height (contract)
solenoid, the pump-isolate (forward) solenoid and the
pump-isolate (reverse) solenoid.
4.15 The board also passes signals to the main control
board from the cover micros witches.
4.16 Any inductive overswings from the solenoids are
blocked by diodes Dl to D4. PL7 on the base distribution
board is connected via a 14-way ribbon cab le to J4 on the
main control board.
Top-of-column distribution board
4.17 This board connects to J2 on the main control
board via a 34-way retractable ribbon cable which
terminates on PL1 of this board. It distributes signals to
10-way hand control/f ootswitch sock ets PL2 and PL3, and
to:
? the level tilt s witch via PL7
? the Trend level position microswitch via PL5
? the lateral tilt opto board via PL4
? the break level position micros witch via PL6
? top-of-column solenoids board via PL8
? the on/off switch via PL9
? proximity sensors on long trunk via J10/11/12.
Top-of-column solenoids board
4.18 This board receives signals on J7 via a 10-way
ribbon cable from J8 on the top-of-column distributor board
to drive the top-of-column solenoids via cage clamp
connectors J1 to J6. It also blocks inductive overswings
from solenoids using diodes D1 to D6.
Tilt opto board
4.19 The tilt opto board is fitted at the top of the column
in a fixed position relativ e to the yoke. It responds to a metal
plate which moves with the y oke and hence with the tab le
top. When the reflector mo v es in front of the opto sensors
electrical signals are generated to signal the main control
board that the table is lev el.
4.20 When the reflector plate moves in front of the
opto sensor, a logic signal 0 is produced which passes
via J1 on the opto board to the top of column
distribution board and then via a 10-way ribbon cable
to J2-4 on the main control board.
4.21 When the reflector plate is not in front of the
opto sensor, a logic signal 1 is produced which is
passed to the main control board as above.
Power circuits
4.22 The power source for the table is two 12V, 24Ah
sealed lead acid batteries connected in series. A 30A inline, high current fuse protects the batteries, motor, FET
relay board and interconnections.
4.23 Current from the batteries passes via the reversing
relay , where it is s witched by the FET’ s, and then passes to
the pump motor and returns to the batteries. The 24V d.c.
supply is also routed to the hydraulic solenoids and the
main control board.
Hand control
4.24 The RX600 hand control communicates with the
main control board via an RS485 serial communication link.
The hand control contains a microcontroller which receives
inputs from the hand control buttons and generates outputs
which go to the hand control LED’s and the hand control
audible warning device. The microcontroller uses software
to implement hand control, control functions.
4.25 The hand-control incorporates a 2-digit display that
indicates a code if a problem should occur. Such prob lems
could be the result of the user pushing a button in the wrong
sequence or at the wrong time or of a system failure (see
T able 1 - F ault Diagnosis, T ab le 2 - Codes for 2-Digit display
and Fig. 31)
Footswitch (optional accessory)
4.26 The footswitch plugs into either of the two 10-w a y
sockets used by the hand control. It uses the same +5V
d.c. and 0V pins, b ut the signal lines are different from those
of the hand control. The footswitch does not use a serial
communication link.
4.27 There are four functions on the foots witch:
? Height up.
? Height down.
? Trendelenburg.
? Reverse T rendelenb urg.
4.28 Each of these four functions is associated with two
microswitches mounted inside the body of the foots witch,
one normally open and the other normally closed. The
normally open microswitch for each function is connected
on one side to the +5V d.c. line and on the other side to a
common ‘alarm’ line. The normally closed microswitch for
each function is connected on one side to the 0V line and
on the other side to an individual input line on the main
control board. If , for any function of the foots witch, e.g. height
up, the normally open microswitch operates and the
normally closed microswitch does not, or vice versa, the
main control board will recognise a fault and freeze the
table. The lik elihood of two microswitches failing at the same
time is very remote.

OPERATION TABLE
Table base ON/OFF control
4.29 The table is switched ‘on’ and ‘off’ by selecting
and respectiv ely . When switched ‘on’, 24V d.c. is switched
directly to the main control board. When it is switched ‘off’
the main control board is isolated from the 24V d.c. supply.
T o isolate the system the 30Amp fuse should be remo ved.
Built-in battery charger
4.30 This is a internal low current output ‘trickle’ charger,
which replenishes an average day’s table use of the
batteries with an overnight charge.
4.31 The mains input comes via the mains lead, which
should be fitted with a fused plug. The output of the charger
is regulated to provide 27.6V d.c. to the batteries for float
charging. This voltage will fall when the batteries are not
completely charged and hence are drawing a significant
current. The charger has short-circuit and thermal
protection. There is an output from the board which supplies
current to the batteries, an output to the ‘trickle’ charger
indicator LED and an input from the external charger.
Current from either the internal or the external charger is
routed to the batteries via the ‘trickle’ charger board.
External battery charger (optional accessory)
4.32 The external battery charger plugs into the external
battery charger socket in the table base and supplies
current via the ‘trickle’ charger board to fast-charge the
batteries.
Standby system connections
4.33 An RX Standby Unit (optional accessory) which
provides standby hydr aulic and electrical services, can be
connected to the RX600 table via hydraulic connectors and
an electrical socket behind a door on the table base.
4.34 Next to the hydraulic connectors are two pushbuttons which release stored hydraulic pressure when the
standby hydraulic connections are first made . This is done
by energizing the pump forward and re verse solenoids with
power from the standby unit.
4.35 To connect the standby unit to the table it is
necessary to open the base door. This operates a
microswitch which disconnects the main control board
solenoid control circuits from the solenoids so that they
can be controlled by the standby unit, also the pump motor
is hydraulically isolated from the hydraulic solenoids. The
electrical signals from the standby socket pass to J1 on
the main control board (15-way D-connector).
Traction beam stowage detection
4.36 Proximity sensors fitted in the underside of the long
trunk section detect the traction beams when they are in
their stowed position. The sensors signal the tab le control
system to stop the table top being driven down onto the
stowed traction beams.

GENERAL
6.1 Maintenance of the RX600 Powered Operation
Table falls into the following categories:
Cleaning and storage. Adjustments.
General care and lubrication. Remov al and Installation.
Functional checks. Fault diagnosis.
Hydraulic system.
CLEANING AND STORAGE
WARNING
Always switch off table at table ‘ON/OFF’
switch (item 18, Fig. 1) prior to cleaning.
6.2 For cleaning and storage instructions refer to
RX600 Powered Operation Table Instruction for Use
(Publication No . T-IM33 issue ‘d’ or later).
6.3 For cleaning and storage instructions of the tab le
accessories refer to the Accessory Instructions for Use
(Publication No. T-IM56).
Note: If the tab le is to be stored for any length of time the
head and leg sections should be fully lowered. This is
necessary to ensure that the gas spring seals and pistons
are kept fully lubricated.
alternative leg section, examine the release handle
for signs of damage.
iii Check the guide pin retaining screw for tightness.
iv On the head and alternative leg section, check the
hinge and gas spring pivots for security (grub screws
or starlock washers, whichever fitted), particularly
the main hinge pivot pin. (Note that the grub screw
for the main hinge pivot pin is underneath the
radiographic top.)
v Check the side bars for security.
vi Examine the guide pin locking button on the hip , and
pre-traction leg support sections, and the release
latch on the Sacral extension for damage. Apply a
smear of light machine oil to all moving parts.
vii On the infill section, examine the guide pin locking
button devices for damage and ensure that the
mechanism, which prevents removal of the infill
section before any attached section has been
removed, functions correctly (ref er to section 6.49).
Apply a smear of light machine oil to all moving parts.
GENERAL CARE AND LUBRICATION
6.4 Once a week proceed as follo ws:
Gas Springs
WARNING
The gas springs are filled with high pressure
gas. Do not attempt to open them.
CAUTION
Gas springs MUST NOT be
additionally lubricated.
6.5 The gas spring supports for the head section are
sealed units which require no routine maintenance.
Malfunction of a gas spring makes it impossible to lock the
head section in position. Seepage of fluid indicates a f ailing
unit.
6.6 If a gas spring is faulty, the complete unit must be
renewed, gas springs are non-repairable items (see section
6.44).
Head, hip, pre-traction leg support and
alternative leg sections, and sacral extension
6.7 Service the head, hip, and pre-traction leg support
sections, and sacral extension as f ollo ws:
i Apply a smear of light machine oil to the guide pins
and pivot pins on the head, hip, and pre-tr action leg
sections, and the Sacral extension.
ii Examine all sections, and the sacral extension for
signs of damage, particularly for scoring or bending
of the attachment guide pins. On the head and

Head and hip sections, locking mechanisms
6.8 Remove the head, hip and sacral extension
sections from the table and clean out any collected fluff or
other debris from guide pin sockets in the ends of the trunk
sections, in the sacral extension attachment and location
holes in the crossbeam. Spra y a little aerosol lubricant into
each socket and attachment hole. Check the operation of
the locking mechanisms when re-attaching the sections
(for adjustment refer to section 6.50).
Long and short trunk sections
6.9 Ser vice the long, and short trunk sections as
follows:
i Apply a smear of light machine oil to the pivot pins
on the long and short trunk sections.
ii Examine the guide pin button locking devices for
damage (for adjustment refer to section 6.50). Apply
a smear of light machine oil to all moving parts.
