Allegro™ 6800 Mobile Imaging
1.1 General Description
The Allegro™ 6800 Mobile Imaging Table is designed to safely hold a patient in the
proper position undergoing radiographic or surgical procedures.
It is a stand-alone, single-pedestal AC power or battery-operated table designed to
position a patient in a prone, lateral or supine position during radiographic or surgical
procedures.
The table has a 2” (5 cm) MIZUHO OSI® Tempur-Pedic® pad. The TEMPUR® used in
the manufacture of MIZUHO OSI® pads has viscoelastic properties and is a temperature
sensitive material, becoming softer where the patient’s body is making the most contact
with the surface and remaining firm in areas where less body contact is being made.
Pressure is distributed evenly over the entire surface area. The pad is radiolucent, MR
safe and latex free. The benefits of using MIZUHO OSI® Tempur-Pedic® are improved
pressure management, reduced shear forces and enhanced patient comfort.
The table has four primary electrically powered functions; up/down, left/right lateral roll
(tilt), trendelenburg/reverse trendelenburg and X-Y translation. These motions are
performed by electromechanical actuators and electric stepper motors.
The table is controlled by means of a low voltage hand pendant which has the functions
clearly labeled. In addition to the hand pendant, a joystick controls the X-Y translations
of the table top. Positive floor locks are employed to stabilize the table in the operating
location.

4.4 Joystick Control – Interactive Proportional Speed Control™ (IPSC)
The lateral and longitudinal translation movement of the table is controlled by a joystick
control mounted on the side rail or auxiliary clamp on either side of the table top. The
Allegro™ 6800 has 2 speed ranges of operation for longitudinal travel. Lateral travel is
always performed at the normal speed setting. An illuminated green light on the top of
the joystick control indicates which speed is engaged. A speed button on the top of the
joystick control can be pressed once to switch between speeds. It should be noted that
the joystick provides Interactive Proportional Speed Control™ (IPSC). This means that
the Allegro™ 6800 travel speed will increase from stop to full speed within the selected
range in proportion to how far the joystick is pushed.

Figure 7: Joystick control
To use the joystick control slide it onto the side rail or auxiliary clamp and plug it into the
receptacle labeled joystick on either end of the pedestal of the Allegro™ 6800. The
locking lever of the joystick control must always be rotated toward the pedestal end of
the table to lock it to the side rail or auxiliary clamp. Correct orientation of this lever
insures that the direction of travel of the Allegro™ 6800 will be consistent with the
direction of the joystick movement.
WARNING:
Failure to engage the joystick locking lever in the proper direction will result in
travel in the direction opposite of the joystick motion.
MIZUHOSI 2009 NW0510 Rev. D

The joystick control includes an activation button (red button) that must be depressed to
activate the joystick. This feature prevents unintended motion of the Allegro™ 6800 if
the joystick is inadvertently pushed.
To translate the Allegro™ 6800, press and hold down the JOYSTICK ACTIVATION
button and then push the joystick in the intended direction of travel. Release the
joystick when the desired position is achieved. The table will move at a speed that is
proportional to the position of the joystick from the starting center position. Pushing the
joystick further from center moves the table faster in that direction. Releasing the
joystick activation button stops the table in any position.
NOTE: Although the Allegro™ 6800 is designed to travel laterally and longitudinally at
any tilt or trendelenburg angle, it is recommended not to translate the table at high
speed under full load (i.e. 450 lb. patient) when it is at extreme tilt or trendelenburg
angles.
NOTE: If the joystick is moved off center before the joystick activation button is pressed
the table will start moving at that speed proportional to the position of the joystick. This
can result in sudden jerky or rapid movement of the table top. Therefore, do not move
the joystick off of center before pressing the joystick activation button.

power cord, an on/off circuit breaker switch, wire harnesses, a power supply, a
controller circuit, a hand pendant, a joystick control, floor lock jackscrews, various
electromechanical actuators, two stepper motors and two batteries. The electric motor
driven leadscrew-type actuators manipulating the height, lateral roll and trendelenburg
functions are controlled by the hand pendant. The floor lock buttons raise and lower the
table floor lock feet to the floor. The translation motion of the table top is controlled by
the joystick control and the hand pendant and driven by the stepper motors. Drawing
number 6800-1003 is the Electrical Wiring Diagram for the Allegro™ 6800 Imaging
Table. The input power requirement for this table is 120 VAC 60Hz, 5 Amp or 230 VAC
50Hz 2.5 Amps as indicated on the serial number label. Drawing number 6800-1004 is
the Electrical Wiring Diagram for the 230 volt model 6800 Imaging Table.
7.2 On/Off Circuit Breaker Switch
An illuminated on/off circuit breaker main switch is located on the back of the pedestal
end of the base of the table (see figure 4). When illuminated, it indicates that the table
is plugged into a live electrical outlet and the power is on, (when the table is turned on
using battery power, this switch will not illuminate). This switch also serves as a circuit
breaker. In the event of an overload condition this switch will trip off. To reset, push to
the off position and then the on position.
NOTE: Determine the source of the overload prior to resetting this switch.
7.3 Component Circuit Breakers
The electrical system includes three individual component circuit breakers that provide
protection for the major components of the system. These circuit breakers are located

table under line power.
To ensure proper battery function, it is recommended that the batteries be charged for
at least 3 hours within the previous 48 hours prior to use. The battery status LED on the
hand pendant must be illuminated green when the table is on. The batteries should be
replaced every 5 years or when they fail to hold a charge.
7.7 Power Supply - AC & DC Operation
The system power supply converts AC power, 120-volt, 60Hz or 230-volt, 50Hz into
24VDC (nominal) operational power. There are four 24VDC output ports, each with a
circuit breaker for thermal and short-circuit protection. Two are unregulated at 10-Amps
with voltage between 36VDC and 22VDC depending on load and one at 15-Amps with
voltage between 36VDC and 22VDC depending on load. The fourth DC output port is
regulated at 24VDC +/- .25 ,and has no circuit protection within the power supply tray.
When powered from an AC source, the batteries in series are constantly being charged
at a variable rate depending on the charged state. Battery charge status is monitored by
MIZUHOSI 2009 NW0510 Rev. D
21
the 10-Amp motor controller PCB via a data port on the power supply PCB. A currentsensing circuit switches to DC battery power when it senses no AC power source is
available. The 24VDC battery circuit can power and operate all of the on-board
systems, motors and actuators. When running on DC battery power the power switch
will not illuminate green but LED’s on the hand pendant will illuminate, indicating the
battery circuit powers the table.
7.8 Battery System
The 6800 Allegro™ Table uses two 12-volt batteries in series to provide 24-volts. When
the battery status LED on the hand pendant is red, the batteries require charging. To
charge, plug power cord into an appropriate hospital grade AC outlet and turn the power
switch to on.
WARNING:
While in storage, the batteries should remain charged for a minimum of three (3)
hours a week. Using the table while on AC power will also charge the batteries.
• Normal battery operation is approximately 5 hours at 10% duty cycle.
•
If recharge is required, charge a minimum of three hours. A full charge should be
available after 18 hours.
•
If battery fails to hold a charge it should be replaced. Replace only with identical type
and size battery (see Replacement / Spare Parts List).
•
Replace both batteries at the same time. Also replace foam battery blocks on top of
battery.
•
Batteries should be replaced once every five (5) years.
•
Whenever the battery cover is opened, check battery for signs of corrosion. Battery
terminals should be clean and free from corrosion, oil, grease, dirt, or other
contaminants.
• Battery ordering number: NV0801; failure to use an approved Mizuho OSI battery,
voids warranty and can cause harm to equipment.
1. Turn power switch off, wait 30 seconds for discharge, unplug power cord from wall
outlet.
2. Remove pedestal-end base cover by removing the six screws using 1/8 in hex key.
WARNING:
Disconnect batteries only with power cord unplugged and power switch off.
This symbol indicates the external stud that is at the same potential as the
equipment chassis. If the AC power cable is not connected to an outlet with a
protective earth ground, this external stud should be connected to a protective
earth ground.

3. Connect battery terminals as follows (see figure below):
a. Red wire: Battery A positive terminal to power supply terminal E16.
b. Yellow wire: Battery A negative terminal to battery B positive terminal.
c. Black wire: Battery B negative terminal to power supply terminal E17.
Figure 9: Battery orientation and wiring
Perform the following test to confirm proper battery connection:
1. Verify power cord is unplugged from AC wall outlet.
2. Turn power switch on (utilizing battery power) and verify all hand pendant LED’s
illuminate on and off in sequence.
3. With properly connected batteries, the hand pendant battery status light illuminates
green or red.
• A green battery-status light indicates batteries are charged and installed
correctly.
• A red battery-status light indicates batteries are connected correctly but are in
need of charging. If a charge is required, plug power cord into wall receptacle;
turn power switch on, verify it illuminates green (AC is provided to the charger).
Charge for at least three (3) hours.
NOTE: If this does not happen, immediately turn power switch off; verify proper battery
connections, verify hand pendant is fully connected to table receptacle. Repeat test
again. If problem continues, contact Mizuho OSI Customer Resource Group at 800-7774674 for further assistance.

8.0 CLEANING
8.1 Cleaning And Disinfecting
NOTE: Never pour any liquid directly onto the table. Never subject the Allegro™ 6800
Mobile Imaging Table to any cart or equipment washer.
1. Table exterior
• Exterior surface should be regularly wiped clean with a mild detergent solution and
wiped dry with a soft lint-free cloth.
NOTE: Do not wipe the support rails for the translating table top. These should remain
with a light coat of oil at all times.
• Care should be taken to avoid exposing the table to excessive moisture. Flooding,
fogging or steam cleaning is not recommended.
• Blood or other fluids, etc., if allowed to remain on the table for a long period of time,
will require special cleaning to remove. A 5% acetic acid solution or white vinegar
and water solution is especially good for this purpose.
• Staining and discoloration of plated or stainless steel surfaces can be corrected by
cleaning with a good commercial cleaning compound, such as Stainless Steel Magic
or Acme White Finish, and then buffing the surface by hand.
• To disinfect exterior surface use a quaternary ammonium or similar type disinfectant
compound according to manufacturer's directions for use. Wipe dry with a soft lintfree cloth.
USE OF IODOPHORS WILL CAUSE STAINING
NOTE: Failure to thoroughly dry surface after cleaning and disinfecting may result in
rust.
2. Casters
• Casters should be cleaned and disinfected in the same manner as table exterior.
Access to the casters is achieved by removing the sheet metal enclosures at each
end of the table base.
NOTE: Before removing any sheet metal covers the table must be turned off and
unplugged. Dangerous high voltage may be present in the circuitry under the covers.
This task should be performed by trained technicians only.
3. Table Pad
MIZUHO OSI® Tempur-med® Pad
IMPORTANT:The MIZUHO OSI® Tempur-Pedic® pad should always be stored in a
flat position. It can actually get stiff in cold temperatures and can crack
and break if in a rolled position. It is important that you allow the pad to
warm to room temperature before attempting to utilize or handle it.
• When handling always grasp by the entire thickness of the pad.
MIZUHOSI 2009 NW0510 Rev. D
24
• Do not lift, slide or carry MIZUHO OSI® Tempur-med® pads by grabbing the fabric.
The cover may tear or rip.
• The pad is intended to be cleaned in place. It does not need to be rotated or flipped.
• Clean with standard hospital disinfectants labeled for use on table pads. Always
dilute and rinse per manufacturer’s label instructions. Wipe dry with a lint free cloth.
Do not soak or autoclave pads. The continued use of bleach or highly concentrated
chemicals will void the warranty on the cover.
• When cleaning the bottom of the pad or the table top, simply lift one end of the pad,
and fold it over onto the other end. Clean the pad or the table top then return the
pad to flat on the table top.
4. Table tops
• Disinfect surfaces of table tops according to standard hospital procedure.
8.2 Lubrication
1. Table exterior
No lubrication is necessary.
2. Table interior
The translation and height adjustment sliding mechanisms of the 6800 Imaging Table
require periodic lubrication. There are ten sliders in all and each should be lubricated
with Thomson Linear Lube grease (or equivalent) once a year. Four sliders are on the
lateral translation rails, four are on the longitudinal translation rails and two are on the
main table column. Apply the grease through the zerk fittings located on each slide
bearing housing. Do not over lubricate.
All other components are lubricated for life at the factory and no other lubrication on the
table is necessary.
8.3 Table Storage
When not in use the table should be stored in a clean dry environment with temperature
between 32 °F & 120 °F (0 °C & 49 °C).
MIZUHOSI 2009 NW0510 Rev. D

Table floor lock system test procedure:
Using hand pendant and control panel, operate floor lock and unlock buttons through
their full range and verify that
1. All four floor lock motors move while the button is pressed and all motors stop when
the button is released.
2. The floor lock LOCKED WHEN LIT light illuminates green when all four motor feet
are extended and all motors stop.
3. The floor lock STOWED WHEN LIT light illuminates amber when all four motor feet
are retracted and motors stop.
4. After the light, amber or green, illuminates all motors stop even when the button is
held.
NOTE: If the floor lock motors appear to be out of sync (excessive travel distance
between the group), this may indicate problems with the motor, gearbox or the
stepper controller PCB.
10.7 Tilt Sensor Actuator
Tilt level sensor assembly:
The tilt sensor controls the trendelenburg and tilt table levels. This sensor assembly is
protected by the X-Y stage and tilt covers. Removal of the covers requires movement
of the table system before, during and after the disassembly process. It is
recommended that the power be turned off and the table unplugged, during the removal
of the covers. After removal, and/or assembly of the tilt level sensor, a calibration
sequence, extreme caution must be taken to ensure safety to the operator and to the
table. Following are the steps required for access, removal, replacement and/or
calibration:
