PROPRIETARY AND CONFIDENTIAL DRAFT March 08, 2017 Standard functions Chapter 1: Introduction - description

Standard functions Electrical function management The electrical functions are managed by controls built into the half-siderails. They are used to disable and enable the electrical functions.

HiLow

2

The HiLow system is made up of two independent oscillating elevation arms that are articulated on the bed frame and slide into the sections of the chassis. The motors are attached to the bed frame and to the elevation arm.

Translation adjustable head section The AHS function combines the upwards and sideways movements of the head section towards the head of the bed. These combined movements increase the sitting surface for greater patient comfort when seated.

NOTE:

3

The bed is fitted with an angular marker for the head section that is built into the slider system.

Head section CPR function The Hill-Rom® 900 Accella™ Bed features a CPR function for the head section for cardio-pulmonary resuscitation. CPR handle The yellow CPR handles on either side of, or under, the head section are used to disengage the driving gear located inside the adjustable head section motor. The head section then descends by gravity. The movement is assisted and cushioned by the actuator until the section reaches the rubber stop on the bed frame. This automatically levels the bed's HiLow with the highest side CPR button This function is activated by pressing and holding the CPR button on the caregiver half-siderail keypads. This returns all sections of the sleep surface to the flat position and levels the bed frame with the lowest side.

Brakes The Hill-Rom® 900 Accella™ Bed has a central braking system that is controlled by a single brake bar. The brakes are applied simultaneously to the four casters by a hexagonal bar at the foot of the bed that controls two linkage bars in each section of the chassis, which actuate a hexagonal bar on each side of the head end of the bed. The brake bar is directly mounted on the foot end hexagonal bar of the bed.

Standard steering The Hill-Rom® 900 Accella™ Bed features a steering function for easier handling when moving the bed or transferring a patient. The steering caster on the right-hand side at the head of the bed (as seen by the patient) or on the lefthand side at the head of the bed* can be locked in the longitudinal axis of the bed by raising the brake bar.

Endboards The Hill-Rom® 900 Accella™ Bed is fitted with headboards and footboards. These endboards can be extracted vertically. They make the bed easier to move and steer thanks to the built-in handles. The boards are also fitted with sleeves for quick installation on the cross members at the head and the foot of the bed. The headboard and footboard are not interchangeable.

Hard surfaces The articulated hard surfaces are made of thick laminate. They can be removed and attached using a system of clips.

Bumpers The protective stops are positioned on the four corners of the bed frame on beds with mobile headboards. On fixed headboards: two at the foot of the frame and two at the head of the chassis.

IV pole and patient helper receptacles The Hill-Rom® 900 Accella™ Bed has four receptacles (two at the head end and two at the foot end) for IV poles. The two receptacles at the head end can also be used to install a patient helper.

Accessory support and bottle holder support pins The Hill-Rom® 900 Accella™ Bed is fitted with eight accessory support pins (Hill-Rom accessories, drainage bags, etc.). They are located on either side of the middle and rear sections of the bed beneath the sleep surface. Page 1 - 4

PROPRIETARY AND CONFIDENTIAL DRAFT March 08, 2017 Standard functions Chapter 1: Introduction - description

Articulated sections of the sleep surface The sleep surface of the Hill-Rom® 900 Accella™ Bed is made up of three articulated sections: the adjustable head section, the adjustable thigh section and the mechanical adjustable foot section. Two racks are used to adjust the angle of the AFS.

Autocontour function The Autocontour function prevents the patient from sliding towards the foot of the bed when the head section is raised. When the raise HS function is activated, the head section is raised from the horizontal position, and then the head and thigh sections are raised simultaneously after 5 seconds. The thigh section rises to the fully raised position (28°) and the head section continues its movement. When the lower HS is activated, the head section is raised and the sections then descend simultaneously after 5 seconds. The thigh section descends to its lowered position and the head section continues its movement.

NOTE:

The Autocontour function is disabled if the ATS is locked.

Trendelenburg/Reverse Trendelenburg The sleep surface can be titled in two ways: – Reverse Trendelenburg: foot end in low position. – Trendelenburg: the head end is lowered The maximum angle for Trendelenburg/Reverse Trendelenburg is available at all heights of the sleep surface.

NOTE:

This function can be used without a mains power supply thanks to the battery.

NOTE:

A spirit level is built into the foot half-siderails to indicate the angle of the sleep surface in relation to the horizontal plane.

Half-siderails The head half-siderails are attached to the head section and are equipped with control keypads used to manage the bed's electrical functions. The foot half-siderails are attached to the bed frame.

Hill-Rom® 900 Accella™ Bed (LI900B4) Service Manual - 196238(2)

The half-siderails can be placed in two positions (low and high). The halfsiderail audibly clicks into the high position for greater safety. They can be turned towards the exterior of the bed and the downward movement is damped by a gas actuator.

Casters The Hill-Rom® 900 Accella™ Bed is fitted with four swiveling casters at the four corners of the bed. The bed is fitted with four casters (three brake casters and one brake and steering caster), each with a 30° incline control mechanism and three positions: • Brake caster: Brake/Neutral/Neutral • Steer caster: Brake/Neutral/Steer The standard caster can be replaced with an anti-static brake caster. It is identified by a yellow dot on the tread (single band) or in the center of the caster (double band). It is located to the left of the sleep surface at the head end (if there is a steering caster at the foot end) or at the foot end (if there is a steering caster at the head end).

The Hill-Rom® 900 Accella™ Bed complies with the standard EN60601-252 (for more details, refer to “Regulatory requirements” page 1-13). All beds are tested prior to delivery, and grounding and equalization of potentials and current leaks are verified.

Page 1 - 8

The ECU is comprised of several main parts used for controlling and powering the bed's different functions: • one transformer. • one power supply board (PSMB). • one motor control board. (MCB) • one scale control board (SCB). • one interface control board (ICB). • one nurse call board (NCB). • batteries. • a connector for maintenance appliances (CAN). Transformer The power stage is made up of a transformer, protected at the input by two delayed fuses (see table 1-4 page 1-8), and a rectifier bridge and filter capacitor at the output. The output voltage of approximately 33 VAC is not regulated. Its voltage varies around 24 V DC, depending on the power requirement. The transformer is also protected by a non-resettable internal thermal protection for the 230V version and a resettable internal thermal protection for the 120V version. Power supply board (PSMB) The PSMB powers the MCB and the ICB. The board ensures that the back-up batteries and emergency functions are charged. The output power is used to control several function simultaneously. Motor control board (MCB) This board controls the bed's different electrical functions: HiLow, adjustable head and thigh sections with Autocontour, brake alarm, chair position, return to the flat position, bed exit and Boost™. It is powered by the ICB. The board is controlled by a microcontroller and controls the motors by relays. In order to protect these relays from electrical arcing during switching, an FET transistor that is common to all the outputs checks the power after a delay when a function is activated, allowing the relays to switch off. The input voltage of the motors is rectified and filtered. The input voltage of the PCBs is rectified, filtered and regulated.

Scale control board (SCB) This is powered by the ICB and performs the following functions: • control of the system by microcontroller. • reading and analog-digital conversion of the weigh cell signals. • transfer of data to the displays. • detection of longitudinal and/or tilting of the sleep surface by +/- 2°. • data storage (weight, tare, etc.) in an EEPROM. • monitoring of the power supplies that reset the microcontroller in the event of a power supply problem. Interface control board (ICB) Controls the communications between the various boards and the connected systems, such as the graphical caregiver interface (GCI), the HiLow pedal, the brake alarm, the night light, the accelerometer (HOB), the patient position monitoring (PPM), the nurse call system, the loudspeaker and the connector for maintenance appliances (CAN). Nurse call board (NCB) The nurse call board transfers the alarm signals to the caregivers via HillRom's Navicare™ system. Connection (CAN) The bed features a socket for connecting a maintenance device. • All devices connected to this socket (CAN) must meet the requirements of IEC 60950-1. Batteries These batteries can be used to operate the bed's functions when the mains power supply is not available. The charging circuit in the power supply unit has a current limiter, according to the level of the battery charge. Charging begins as soon as the unit is connected to AC power. At the end of charging, the load current is very low. An audible low battery alarm buzzer sounds during movement if the battery voltage drops (a continuous beep heard each time a control is pressed). In addition, an LED on the caregiver's half-siderail keypads indicates the battery charge level.

The sealed lead acid batteries are series connected to the main PCB and protected by a fuse on the connecting wires. The battery type has no memory effect and can be charged regularly without any particular constraints. Recap of the memory effect: certain types of battery (Nickel Cadmium) must be fully discharged before being recharged. Disregarding this caution may cause significantly reduce their service life. Battery capacity after a full recharge with safe working load on the bed: One complete HiLow, HS, TS and T/RT raise/lower cycle before alarm, then one more complete cycle.

Power-driven actuators

2 3

Siderail keypads

Four separate motor-driven actuators powered by the MCB are used to operate the bed’s different electrical functions. They are all designed to withstand the risks of ingress of liquids under normal conditions of use. The AHS and ATS actuators only operate in thrust mode. When the rod is retracted, the AHS and ATS can disengage to avoid the risk of entrapment between the section and the structure of the bed frame. The section is lowered by the weight of the head and thigh sections. This function is also used to raise the head section manually without actuating the CPR handle. The upper and lower internal end of travel stops (EOT), detected when the motors reach their end positions, are controlled by the MCB. All movements can only be made by pressing and holding the button of the corresponding function. (There are no automatic movements, except for the mechanical CPR (See “CPR handle” page 1 - 4)). Depending on the function, one button corresponds to the movement of one or more motors (Autocontour). Table 1-7.

“Bed connected to mains power, brake not applied” detection* The detection system operates using a NF switch, mounted on the foot end crossbar that is activated by the hexagonal brake bar. The power supply unit triggers an audible alarm if the following two circumstances occur at the same time: presence of mains voltage and switch not activated. The audible alarm stops when the brake is applied or if the bed is unplugged from the mains. Page 1 - 10

The bed is fitted with two siderail keypads on either side of the head halfsiderails. • patient siderail keypad, • caregiver siderail keypad. Each of the siderail keypads is made up of a cup panel connected to an junction PCB, which in turn is connected to the ICB.

Graphical Caregiver Interface (GCI)® The graphical caregiver interface is made up of the screen and the HIB. It is used to control the various interfaces, such as the weigh system, the bed exit alerts, the adjustable head section angle alert and the user preferences and provides technicians with access for maintenance and calibration purposes.

Weigh system The four weigh cells are connected to the weigh PCB which permanently analyzes the incoming signals. The analyzed data is displayed on the siderail display (GCI) according to the user's actions.

Fault indicator Service required The indicator lights flash in the event of various faults. The cause of the fault can be: 1. A faulty component, 2. Battery low, 3. Micro-power cut, 4. A person sitting on the side of the bed. In case 2, refer to tableau 1-5 page 1-9. In case 3, press a key. In case 4, ask the person to stand up. If the indicator light still flashes, proceed with troubleshooting (See “Operational checks” page 2 - 5).

Night lights The night lights are under the electrical control unit. They can be switched on and off on the caregiver keypads. Once activated, the night light comes on and changes color according to the height of the sleep surface. • Green: the bed is in the low position. • Orange: the bed is not in the low position.
