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 box via a
three-core mains cable (in 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. A filter is 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 box has two 1,6A fuses for the 230V version (2x 3,15A for the low voltage versions – 100, 110, 127
V). The power unit is a part of the control box.

3.1.2 Control unit
The power unit and control unit are implemented together in one plastic box. The control box is located on the mattress platform.
The Eleganza 2 bed is equipped with a PB43 control box or alternatively with a PB21 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 unit
also contains inputs for an undercarriage module and an add-on matrix controller.
The PB43 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 "3.1.2.1 Control unit modes and safety functions" - "Lifting units speed synchronisation (calibration) (PB43only)" of the mattress platform, and locking the units.
The PB21 control box is a more basic version of the PB 43. Compared to the control unit PB43, it does not contain audible signals,
overcurrent protection, synchronisation (calibration) of lifting units speed and allows only some controls to be connected.

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 electronic system. The default general requirement is the safety of the system when there is one fault. The basic safety features are:
» Lifting units speed synchronisation (calibration) (PB43only)
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. Synchronisation must be performed after each change of column, control unit, and
accelerometer (more in chapter "4.1 Synchronisation of column units").
» STOP button located on the ACP panel
The main STOP button immediately stops all movements of the bed (undesirable movement) and deactivates GO if positioning
is not permitted or during failure of electrical components. A 10 kΩ resistor is connected in parallel to the STOP button inside the
keypad. The electronics of the system detect the correct connection of the resistor (connection of keypad and functionality of the
STOP button). Its interruption (error in keypad, faulty resistor, cable...) is signalled by an intermittent tone from the control unit.
Without correct connection of ACP controller to the resistors, this function after activation with the GO button is only active for 5s.
» 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.
» Recognition of simultaneous pressing of any two buttons
The control unit is issued with the function for recognizing two pressed buttons at the same time. When two buttons are pressed
at the same time, control unit blocks function. Unblocking is automatic after all presses have been released (including the error
ones).
» RC circuits – protection against shorting and spontaneous movement
An RC circuit is installed in all the analogue control elements connected to the ACP control unit (ACP, handset, Mob-Lift, foot controller). The value of the RC circuit resistor is 390 Ω. If the function is not active, the circuit resistance is infinite as standard. When
any function is pressed, the resistance of the circuit is 390 Ω, the function is detected as valid and it begins. If a short is present
in the circuit of the button, the resistance drops below 200 Ω, the control unit detects the function as invalid and positioning does
not occur. The RC circuit serves to prevent spontaneous movements of the bed caused by short circuit in the wiring.
≥ 1 kΩ - Leakage
390 Ω - OK
0 < 200 Ω - Short circuit
» 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
D9S001GRA-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.
» Overload detection (PB43 only)
While monitoring current drawn by the motor units, the electronics stabilise the maximum current and thus partially limit start-up
current peaks. If a constant current overload is detected, movement is halted after approximately 1 second.
» 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 connectors of the same type (telephone ones) are used, mixing them up during assembly or servicing does not lead to damage of the
control unit.

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.

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.
The synchronisation must be performed after each change of:
a) any lifting unit
b) control unit
NOTE:
Calibrating of columns means: Calibrating the control box to equate the speed of both columns 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
5.1.1 Column calibration using the ACP
► Ensure the bed is on a level floor!
► 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

► Check whether you are in calibration mode. The lock functions and battery LEDs should be flashing on the ACP control
panel as well as the lock function LEDs on the hand control. This mode is only active for 1 minute.
► Press and hold the CPR button (3). The bed will go UP, DOWN and UP. After each end position one LED lock will turn off.
In case of unpressed CPR button during the calibration, the calibration stops and must be repeated
► The columns are now calibrated to move at the same speed.

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.
