Product Description
The Contoura® C980B Series are acute care beds designed to accommodate patients weighing up to 250kg. The beds have multiple patient positioning functions and other features to aid patient therapy. A self-contained weighing system enables continuous monitoring of patient weight and weight change. The bed has a four-section profiling mattress platform with power driven adjustment of bed height, two-way tilt angle, backrest angle and leg elevation. Kneebreak angle is manually adjustable with power assistance by gas spring. The mattress platform incorporates a built-in bed extension and removable (lift off) headboard and footboard. Revolving buffers are provided on all four corners. The bed may be supplied with single section (¾ length) safety sides or split safety sides, the latter having two sections which may be raised or lowered independently. The bed is mounted on four 125mm or 150mm castors with braking and steering facility. The complete base of the bed is enclosed by a moulded cover.

746-270-3 02/10
On all models the power driven functions of height, backrest angle and leg elevation are operated by push button controls. The Auto Contour button simultaneously operates both backrest and leg elevation. The push button handset(s) is accessible to either patient or attendant. It may be pendant type or built-in to split safety sides. An additional handset, for use by the attendant, is stored beneath the Attendant Control Panel (ACP) at the foot of the bed. Tilt angle can be controlled only from the attendant handset. The ACP enables the power driven functions to be individually disabled. Operation of the bed by the patient is thus at the discretion of the attendant. The electrical actuators consist of a screw and nut assembly driven by a 24V d.c. motor and gearbox. Power for the actuators is derived from a mains operated d.c. power supply with emergency battery back up. A built-in power socket allows Huntleigh Healthcare air mattresses to be connected directly to the bed. The socket is supplied from an uninterruptable power supply (UPS) which will maintain operation of the mattress system in the event of mains power failure or when the bed is being moved. Some Models may be supplied without the power socket and UPS. The bed is equipped with an integral patient weighing system, which is supplied with power from the UPS (if fitted). Model C985B bed is equipped with an X-ray translucent backrest incorporating a cassette carrier to provide the facility for chest X-ray photography. Model C988B bed is equipped with a full-length X-ray translucent mattress platform, allowing head-to-toe X-ray photography to be carried out.

Patient Weighing System
1.4.1 General
Four load cells are installed in the bed frame. The electrical output signals from the load cells are integrated in a load converter (QLC) which provides a single output to the user interface. Separate displays are provided for patient weight and patient weight change. 1.4.2 Accuracy
The weighing system is very sensitive and will be affected by a number of outside influences. It is therefore important that the following criteria are observed. a)
The bed must be installed on a flat and level floor.
b)
The transport screws must be fully disengaged prior to use (Figure 113).
c)
The bed should be positioned clear of obstructions such as walls, furniture, trailing leads or curtains. 1-13
746-270-3 02/10
d)
The weighing system should be used within the normal operating ambient temperature range of 10°C to 40°C.
e)
For best results, the patient should be positioned approximately centrally on the bed.
f)
The weighing system is capable of detecting relatively small movements of the patient. It is therefore necessary for patient movement to be minimised during the few seconds required to obtain a stabilised reading and that the operator / nurse stands clear of the bed during this time.
g)
When weighing, the handsets must be replaced in position on the platform.

Error Indications
1.5.1 (1) Zeroing Error
A series of horizontal dashes along the centre of the display indicates a zeroing error. In order to maintain accuracy over its weighing range, the system can only be set to zero within 50kg of the original calibrated zero. The dashes indicate that an excessive amount of equipment has been added to the bed prior to setting the initial zero. This is why it is recommended that only the mattress and bed linen are added to the bed prior to setting zero for the bed. To clear this error: remove all equipment from the bed except mattress and bed linen. Disconnect the weighing system from the power supply (turn off the UPS) for a few seconds. Reconnect the power supply and then re-zero the displays. 1-19
746-270-3 02/10
When installing additional equipment on the bed, use the auto-compensation facility. 1.5.2 (2) Overload Error
A series of horizontal dashes along the top edge of the display indicates that the safe working load of 250kg has been exceeded. This means either the patient is too heavy for the bed or an excessive amount of equipment has been added to the bed prior to placing the patient on the bed. If the latter is the case, remove equipment from the bed using the auto-compensation facility. 1.5.3 (3) Auto-Compensation Error
A series of horizontal dashes along the lower edge of the display indicates that the allowable limit for added equipment of 100kg has been exceeded. To clear this error, press the Reset button. The display will revert to showing gross weight. To proceed, remove all additional equipment from the bed, thereby returning to a display showing patient weight. Then, using the autocompensation facility, replace all the additional equipment previously fitted. Alternatively, remove the last piece of equipment added and manually input the patient weight. If, when the Reset button is pressed, a series of horizontal dashes appear along the top edge of the display, this indicates an overload condition. Refer to (2) above.

Uninterruptable Power Supply (UPS)
The UPS is located in an enclosure on the base of the bed at the head-end. It provides mains power to the outlet socket at the foot end of the bed, as well as to the patient weighing system. When the bed is disconnected from the mains power supply the UPS will continue to provide this power derived from its internal batteries.
Figure 1-15 UPS on/off switch 1.6.1 Pulsar Ellipse 500/800
To turn the UPS on: Open the cover (1) on the patient’s left-hand side of the UPS enclosure, press and hold the on / off button (2) for approximately 10 seconds. The button contains an LED that will be green in normal circumstances. To turn the UPS off: Open the cover (1) and press the on/off button (2). An audible warning beep sounds when the mains power is disconnected and the UPS is in operation. If this occurs, restore mains power to the bed as soon as possible. If the unit continues to beep when the mains power is restored, contact Huntleigh Healthcare. If the UPS has been in use and its internal batteries have become discharged, reconnect to the mains power supply then turn the UPS off and back on again as described above. This will reinitialise the UPS and, over an eighthour period, recharge the batteries to full capacity.
1.6.2 Pulsar Ellipse 750
To turn the UPS on: Open the cover (1) on the patient’s left-hand side of the UPS enclosure, press and hold the on / off button (2) for about one second. A green LED in the button lights to indicate the UPS is operational.
1-21
746-270-3 02/10
To turn the UPS off: Open the cover (1), press and hold the on/off button (2) for more than two seconds. The green LED in the button will go out.
A red LED to the right of the on/off switch indicates UPS status. If the LED is on, the UPS has developed a fault; if the LED flashes, the UPS battery should be replaced. Refer to Section 6.
If mains power is disconnected while the UPS is switched on, the green LED in the button (2) flashes and an audible warning beep sounds every 10 seconds; this changes to every three seconds when the UPS battery is almost discharged. If this occurs, restore mains power to the bed as soon as possible. If the unit continues to beep after mains power is restored, contact Huntleigh Healthcare. If the UPS internal battery has become discharged, reconnect the bed to the mains power supply to recharge the battery to full capacity; this may take up to eight hours if the battery was completely discharged.

OPERATIONAL MAINTENANCE
2.1
General
The equipment has been designed to be virtually maintenance-free between service intervals. The degree of periodic cleaning and maintenance necessary will be determined by use and condition. Examine the bed for obvious signs of damage. If found take appropriate remedial action.
WARNING Disconnect the bed from the electricity supply and switch off the UPS before carrying out cleaning procedures. 2.2
Cleaning
Wearing suitable protective clothing, clean all surfaces with a disposable cloth soaked in a neutral detergent and hand hot water. The mattress platform sheets and head/foot end panels can be removed from the bed and cleaned separately. Start by cleaning the upper sections of the bed and work along all horizontal surfaces. Work methodically towards the lower sections of the bed and clean the wheels last. Take extra care to clean areas that may trap dust or dirt.

Disposal of product and components should be compliant with local regulations.
WARNING Before starting any maintenance activity, disconnect the bed from the electrical power supply and switch off the UPS. Avoid skin contact with lubricants. Gloves and protective clothing should be worn when carrying out maintenance work. 3.1
General
Examine the bed for obvious signs of damage. Make sure that all visible fixings and fastenings are secure and not missing. Examine the flexible mains and handset cables for cuts, abrasions, kinks or other deterioration. Check the power connector plug for damage. Check that the adapter fuse is of the correct type and rating (BS 1362, 5A – UK only). If the power connector plug or cable is damaged, they must be replaced as a complete assembly. 3.2
Release Cables
After long use, release cables may stretch. This could prevent proper operation of the CPR release. To remedy this, adjust the two lock nuts on the inner cable at the release lever end. Refer to Section 6, sub-section 6.24 and 6.25. 3.3
Castors and Brakes
Check the brakes for efficient operation. Apply the brakes and push the bed. If any of the castors rotate, the brake is not fully effective. Set the brake pedal in the steering position and verify that one head end castor is engaged so that it cannot swivel. 3-1
746-270-3 02/10
Brakes that fail to lock effectively indicate that the castor requires adjustment or replacement. Refer to Section 6, subsections 6.6 and 6.7. 3.4
Batteries
If, when the bed is operated using the batteries a bleeping sound is heard, this indicates a low charge condition. The bed should be re-connected to the mains power supply, for a minimum of 24 hours, in order to recharge the batteries. Check the condition of the batteries using the following procedure: 1. Ensure that the bed has been connected to the mains power supply for 24 hours. 2. Disconnect the bed from the mains power supply. 3. Apply a load of 80 kg (= 12 stone person) to the mattress platform. 4. Raise and lower the mattress platform, from minimum to maximum height, three times. 5. If the bed does not operate satisfactorily in step 4, perform steps 1 to 4 again. If the bed again fails to operate satisfactorily, the batteries are not holding sufficient charge and they should be replaced. Refer to Section 6, subsection 6.12. 3.5
Safety Sides
Check the safety sides for obvious signs of damage. Make sure that all nuts, bolts and other fastenings are secure and not missing. Make sure that the mechanism that locks the safety side in the raised position engages positively. 3.6

CALIBRATION
7.1
Calibration of Height/Tilt Actuators
Minor accumulated errors in service may result in lost position (nonparallelism) of the height actuators, as a result of which the bed may not return to a true horizontal position. This may be automatically corrected by driving the bed to its lowest height. If this is not effective, the condition can be rectified by the re-calibration procedure described below. 7.1.1 Preliminary
Ensure that the bed is connected to the mains power supply. Set the rotary ‘lock-out’ switches on the attendant control panel to enable all the bed functions. Raise the leg section to about 5°. 7.1.2 Procedure
a)
On any of the patient control handsets, press any three of the top four buttons simultaneously and keep them pressed.
b)
A continuous beep sound should be heard from the control box. If not, repeat step a).
c)
After approximately 5 seconds, the continuous sound should change to an intermittent beep. (This indicates that the control box is in calibration mode.) Release the push buttons.
d)
Press the Height Down button for a few seconds. (This will drive one of the base actuators inwards.)
e)
Press the Height Up button for a few seconds. (This will drive the other base actuator inwards.)
f)
Repeat steps d) and e) until the deck is level at bottom height.
g)
At this stage the system will recognise that calibration is complete. The intermittent beep will stop and the system will revert back to normal operation.
If at any time during calibration there is a period of more than 5 seconds before a button is operated, the system will revert to normal operation and calibration data will not be stored. Calibration data will only be stored after completion of all steps a) to f) listed above i.e., when both base actuators are fully retracted

APPENDIX A - ASSEMBLY SPARES MANUAL A-1 General The Assembly Spares Manual is for the identification and requisition of replaceable parts. It contains assembly drawings of the equipment and sub-assemblies. Each drawing sheet is accompanied by its related parts list. The Assembly / Spares Manual Modification Record (ASMMR) is the configuration control document for the equipment. The ASMMR identifies the sheet number and issue number of all drawings relevant to a particular equipment. A separate ASMMR is included for each model number covered by this manual.
A-2 How to Use the Assembly Spares Manual Refer to the relevant ASMMR for the equipment model number. By reference to the equipment serial number and the ASMMR, identify the applicable drawing. Find the part on the drawing and note the item number, which is given in a balloon. Refer to the related parts list for information regarding the part. Sometimes a number of identical parts may appear in different locations but only one will be identified with a balloon. The number in the “Qty” column of the parts list indicates the total number of times that the part appears in the drawing. When a part has optional variations, the last column of the parts list refers to a separate drawing sheet defining the choices.

APPENDIX B – DISPOSAL OF GAS SPRINGS The gas spring contains air and oil at high pressure and must be vented in accordance with the following instructions before being discarded. Under no circumstances should any attempt be made to open the device.
WARNING Danger of explosion. Do not heat or incinerate. High pressure gas. The sudden release of gas at high pressure could cause serious injury or death. Put on suitable protective clothing, eye protection and / or a face shield. 1. Operate the valve at the end of the piston rod and allow the piston rod to extend fully. 2. Clamp the gas spring in a vice and drill a hole approximately 3mm diameter at position 1 as shown in Fig. B-1. Screen off the drilling point as metal chips and oil may be ejected due to the high internal pressure. Then drill a second hole at position 2 as shown. The holes should be drilled to a depth of approximately 10mm.
Figure B-1 Disposal of gas spring 3. Operate the valve at the end of the piston rod and push in the piston rod. 4. Drain oil from the gas spring by pumping the piston rod in and out several times. 5.
