3.1.1 Power unit
The power unit transforms input voltage to 24V and sends it to the control unit. Mains power is supplied to the power unit via a
three-core mains cable according to the relevant national standard. The power unit is at a standard voltage of 230V – 50/60 Hz,
and alternatively at a voltage of 100, 110, 127V – 50/60Hz. There is a filter in the mains connector of the power box. The power
unit transformer contains two thermal overloads. The first overload automatically disconnects the voltage at a temperature of
100°C/212°F and reconnects the voltage after cooling down. The second overload disconnects the voltage permanently at a
temperature of 130°C / 266°F. The 24 V AC power unit has two 1,6A fuses for the 230V version (2x 3,15 A for the low voltage
versions– 100, 110, 127 V). The power unit is part of the control box.

Nominal supply voltage AC 230, 100, 110, 127V (±10%) / 50-60 Hz
The Eleganza 1 bed is equipped with a PB43 control box or alternatively with a PB11 control box.
The PB43 unit is used for controlling 4 linear units, with outputs for controllers and a backup rechargeable battery power source.
It is controlled via low-voltage switches and allows the use of membrane keypads. The control unit has 4 outputs for the linear
units, an input for connecting a rechargeable battery, and an input for control panels with safety functions (ACP). The PB43 red
unit also contains inputs for an undercarriage module and an add-on matrix controller. The PB43 red unit is built into the instrument
case and is equipped for dual power from the mains and from batteries. When operating on the mains, the battery is continuously
powered and the battery is recharged as required. The control unit has the function of synchronising the speed of the lift units (see
Synchronisation (calibration) of speed of lift units) of the mattress platform, and locking the units.
The PB11 control box is more basic version of the PB43. Compared to the control box PB43 , it does not contain an audible sig-
nal or overcurrent protection, and allows only some controls to be connected. Also, it does not include synchronisation of the
lifting units.

3.1.2.1 Control unit modes and safety functions
The architecture of the control unit is designed to exclude or significantly limit the risks arising from using a programmable elec-
tronic system. The default general requirement is the safety of the system when there is one fault. The basic safety features are:
» GO button located on the ACP panels, the handset, and side rails
All the control functions are conditioned by the initial pressing of the GO button (only the CPR and the STOP button do not require
the GO button to be previously pressed). When GO is pressed, the control system is activated for 3 minutes (except for the STOP
circuit failure described above). When any function is pressed for more than 2 seconds, the button is released for an extension
of the GO period by another 3 minutes. When a function is pressed for less than 2 seconds, the original time limit of 3 minutes
remains. After 3 minutes from the previously selected function, the control electronics are deactivated and any further function
is conditional on the GO button being pressed again. Pressing the GO button is only valid if no other control button has been
pressed at the same time. The use of the GO button significantly limits the possibility of accidental movement of the bed during a
fault or from unintentional pressing of controllers. For the the US version the GO period lasts 10 minutes.
≥ 1 kΩ - Leakage
390 Ω - OK
» Leaks measuring
The control unit is able to measure leaks in individual controllers in the kΩ range.
If resistance is detected in any of the controllers, it is signalled by all the lock LEDs flashing, the control unit always permitting one
movement of the bed after the STOP button is pressed. Information about the leak is recorded simultaneously in the permanent
memory of the control unit.
10 D9S001GT0-0101
» Positioning functions locks
The locks of the position functions have an electronic design and their actual condition is always saved in an EEPROM type
memory. If case of the locks failure, the LED light under the corresponding lock starts flashing.
» Thermal protection
Built-in thermal protection signals temperature exceeded in the internal cooler and near the switching transistors (approx. 100°C)
during overload. A constant tone signals this condition. After an additional increase of approximately 15°C, the switching power
elements are disconnected (this makes positioning impossible), also signalled by a constant tone. Information about the thermal
overload is recorded simultaneously in the blackbox.
» Connectors
Inputs and outputs of the control units are fitted with different types of connectors, meaning they may not be mixed. If connec-
tors of the same type (telephone ones) are used, mixing them up during assembly or servicing does not lead to damage of the
control unit.
D9S001GT0-0101 11
3.1.3 Battery pack
Lead hermetic rechargeable batteries 2x12V/1.2 Ah are connected
in series in a plastic housing, protected by a 15 A fuse. The plastic
housing is inserted in a control box unit. The rechargeable batteries
serve as an emergency backup power source for the bed while it is
disconnected from the mains electricity or during transport. This type
of rechargeable battery has no memory effect and should not be run
fully flat to increase its lifespan.

Information about charging and the modes of the rechargeable battery are signalled by the battery’s LED (see chapter "4.1.1
Battery faults diagnostics (ACP panel)")
► The manufacturer provides a 6-month warranty for the full function of the accumulator
► Charging of the accumulator before using the bed takes approximately 4 hours
► The battery box cannot be disassembled. The battery unit must be replaced completely

3.2 Linear lifting units
The purpose of the lifting units is to adjust the height of the bed platform.
The motor is equipped with limit switches to indicate the end position. For safety rea-
sons, the upper end switch is doubled up. If the first upper end switch is damaged, the
second one is activated to stop the motor. It is connected by a cable with a 2-pin con-
nector. The maximum current consumption is 5.5 A and the maximum working voltage
is 24 V. Fig. 4 Linear lifting unit

3.3.1 Backrest actuator
The backrest motor lifts the bed's back mattress platform. It is connected to the construction using two pins and secured with
starlock washers. The backrest motor contains a mechanical unblocking function. The head of the motor is connected to the
CPR lever by a steel cable.
The motor is equipped with end switches to indicate the end position. For safety reasons the upper end switch is doubled up. If
the first upper end switch is damaged, the second one is activated to stop the motor. A two-core cable with a repro-Din connector
runs from the motor. The cable is connected to the control unit.

3.4 Controllers
3.4.1 Attendant control panel (ACP)
The ACP is connected to the control unit via a 14-core cable terminated with a 13-pin DIN connector. The ACP panel is connected
directly to the control unit. The attendant control panel includes a STOP button. The ACP contains a lock to block individual control
unit functions, indicator lights for the mode and condition of the rechargeable battery, a selection of special functions, and settings
for the standard positions of the bed. The controller has an RC unit to detect short circuits.
3.4.2 Handset
The handset (Fig. 9) is an optional controller of the bed. The handset is available in two versions, with illuminated buttons or with-
out (or as a variant with mattress platform lift - UP/DOWN). The handset button lighting is active if the bed is connected to the
mains. The functions of both handsets are identical.
A cable with an 8-pin DIN connector is connected to a Plug&Play adaptor, which is linked to the control unit. The controller has
an RC unit to detect short circuits.
D9S001GT0-0101 15
3.4.4 Foot controller (platform height adjustment)
The foot controller for height setting is a paired component of the bed. It is located on the undercarriage at the foot section of the
bed and attached to the undercarriage frame. There are three buttons on the controller – raise, lower and examination position.
A cable runs from the foot controller to the mattress platform and is connected to the control box (position 13). The controllers
are connected to the control box by a DIN connector.
The Mini GO function is included in the software of the control unit for the foot controller. This is a function whereby pressing the
foot controller button once again, the GO period runs for 20 seconds without the need for pressing GO on the siderail controller or
handset. This allows bed positioning without having to use your hands.
16 D9S001GT0-0101
3.5 Night illumination
The control unit allows a pair of illuminating "white" (or green) LEDs to be connected, ensuring illumination of the mattress plat-
form. The night illumination (LEDs) are connected via a ribbon cable to the control unit
A magnetic sensor for the brake alarm is placed on the foot section of the bed undercarriage. The activation magnet is on the brake
operating rod. The magnetic sensor is connected to the control box.

Eleganza 1 is fitted with 4 castors plus an optional 5th castor. If the bed is fitted with a 5th castor, 3 standard castors and one
static castor are used. A bed without a 5th castor must be fitted with a directional castor. The position of the directional castor is
according to the direction control . If the direction control is from foot end, the directional castor is fitted at the right head position.
If direction control is from the head end, the directional castor is located at the left foot position.

5 Bed Setup
5.1 Lifting units speed synchronisation (calibration)
The function to stabilise speed of lift units allows the lift speed of all columns to be synchronized. This makes it possible to maintain
the bed in a horizontal position.
NOTE:
Calibrating of Lifting units means: Calibrating the control box to equate the speed of both lifting actuators during raising and
lowering. Not doing this procedure may cause permanent inclination of mattress platform during normal use.
Connecting the bed to the mains supply and activating the ,,GO‘‘ button is recommended.
► Enter the calibration mode by pressing a combination of four buttons on the nurse control panel - simultaneously press
backrest UP (1), backrest DOWN (2), CPR (3) and anti-Trendelenburg (4) buttons, and hold them for 3 seconds

5.2 RC circuit
5.2.1 Function description and purpose
For improved safety reasons peripheral controls (ACP, patient hand control, siderail controls and Mobi-Lift®) have been fitted with
RC components. These allow the control box to recognize whether a circuit activation is a valid press of a button or a short circuit.
In such a case, the function is blocked as protection against a short circuit. Short circuit protection only works when all controls
are fitted with RC components and the function is activated in the control box.
All Eleganza range beds with serial number 2015xxxxxxx and higher have short circuit detection turned on by default.
Control unit PB43 is equipped with a switching ON or OFF of the short-circuit detection function. Control unit PB43 RED is not
equipped with switching ON or OFF of the short-circuit detection. PB43 RED can only be used on beds produced after 2019.
NOTE:
► Peripheral controls which are equipped with an RC circuit for short-circuit detection are compatible with control units with
short-circuit detection turned ON or OFF.
► Peripheral controls which are not equipped with an RC circuit for short-circuit detection are not compatible with control
units with short-circuit detection turned ON and it is necessary to turn this function OFF in the control unit.
► If there is a one peripheral component which is not equipped with short-circuit detection (does not have an „ST“ or „KA“
{SN 2014 and higher} mark on the handset or „ST“ mark on the ACP) it is necessary to turn OFF the short-circuit detection.
► If the function is controlled by data transfer (undercarriage module), then short-circuits are not detected.
Control unit PB43 SW version: since 6.33 and newer Default: Turned ON
Default: Turned ON
Control unit PB43 RED SW version: since 8.12 and newer
