Main drive

This drive, with its integrated control, or with a drive-mounted control unit, can be connected directly to the power supply unit. A transformer converts the mains voltage to a safe 24/29 V DC, and the drive movements are activated reliably via the integrated control unit. 
Depending on the drive concept, the transformer or SMPS can be integrated directly or alternatively fitted in an external power supply unit. Depending on the type, additional slaves can be connected to the main drive control unit.


Mains isolation

The DewertOkin mains isolation separates the control to the line voltage completely when the actuator is not in use. 
Only when the handset is actually being operated, the actuator will be connected to the line voltage. If no actuator is running, no electricity is being allowed to pass the mains isolation plug, which in turn prevents any electrical or magnetic field in or around the actuator. 
An integrated primary fuse (optional) separates the bed’s plug from the mains in critical cases.


MEDITOUCH

This is the innovative connection system for membrane keypads which completely satisfies the safety requirements in the hospital and care sectors. 
Modern hospital beds are equipped with numerous membrane-operated elements. 
In comparison with conventional cable-operated handsets, this concept offers hospital bed manufacturers greater design freedom, with improved functionality and operating comfort for users. 
MEDITOUCH Patient and MEDITOUCH Nurse membranes can still be connected and also combined. 
MEDITOUCH connects numerous membrane keypads and conventional operating elements with a single handset connection. 
MEDITOUCH is compatible with all CARE/HOSP and FURNIBUS control units. 
MEDITOUCH Nurse: 
A detailed specification of the interface for the functions of the MEDITOUCH Nurse membrane can be provided. 
MEDITOUCH Nurse extends the range of functions of conventional handsets and locking elements. 
It is also possible to block individual functions (e.g. Trendelenburg position / anti-Trendelenburg position, independently of the height). 
The locking or release of functions is effective for all operating elements which are connected to the MEDITOUCH system. 
This means that the MEDITOUCH Nurse takes on the function of a master which, by means of its 28 function keys, controls all the connected operating elements. 
MEDITOUCH Patient: 
A detailed specification of the interface for the functions of the MEDITOUCH Patient membrane can be provided.
MEDITOUCH Patient depicts the range of functions of conventional handsets and operating functions which have been approved for the patient. 
The locking of individual functions (e.g. Trendelenburg position / anti-Trendelenburg position, independently of the height) is not possible. 
This means that the MEDITOUCH Patient takes on the function of a handset which, with 14 function keys, is subordinate to the MEDITOUCH Nurse membrane. 
All drive functions which are released via the MEDITOUCH Nurse membrane can be activated. 
Conventional handset interface: 
The conventional handset interface is not in the microprocessor control unit or FURNIBUS control unit – it is fitted to the standard DEWERT relay controls. 
This communication interface, which was developed especially for DEWERT drive systems, can be used to connect a maximum of two operating elements. 
This standard, which is known worldwide, provides the basis for the efficient and cost-optimised control of medical and furniture drives.


Memory

Memory drive (drive with position recognition): This type of drive is fitted with a system for recognising positions and paths. Information on the current drive position and/or speed is continuously transferred to a control unit which is suitably equipped.
An incremental position feedback system (Hall sensor) is available for almost every DEWERT drive. In addition, some systems can be fitted with an absolute position feedback system (potentiometer). The memory drive is used for applications in which stored comfort positions need to be called up at the press of a button.
They are also necessary in applications which involve complicated movements and with synchronous adjustment movements.
Memory function: The memory function refers to the ability of a control unit to store and keep ready for call-off preferred sitting or lying positions. This requires a drive system with position recognition (memory drive).

Microprocessor control

The adjustment movements of the connected drives are coordinated and monitored via control software which is designed to match the applications. Applications are sophisticated situations in which complex sequences of movement need to be coordinated (e.g. hospital beds).


Microprocessor control FURNIBUS

The adjustment movements of the connected drives are coordinated and monitored via control software which is designed to match the applications. Applications are sophisticated situations in which complex sequences of movement need to be coordinated (e.g. hospital beds). Many control and accessory components are equipped as options with the DEWERT-specific FURNIBUS interface which makes possible the flexible and comfortable crosslinking of intelligent control components.
