MEDICS®includes:
 Display and operating units such as TM… alarm indicator and operator panels or
MK… alarm indicator and test combinations
 Single and three-phase monitoring modules. Examples for such modules for the
MEDICS®system are: UMC…, USC…, UFC… and/or EDS… insulation fault location
systems.
 Communication between these components via the BMS bus (two-wire connec-
tion).
 The connection of third-party technical systems by means of protocol converters
(gateways) or via digital inputs and relay outputs.
The real strength of MEDICS®lies in the communication between all components and
the resulting information for the user. The functionality of the equipment is continu-
ously monitored. Operating states, irregularities, faults and equipment failures are
displayed. This means high operational reliability of the installation for the user.
3.2 Characteristics
On its backlit display (4 x 20 characters), the MK2430 displays messages from all BMS
bus devices assigned via alarm addresses. As well as being used as a standalone
indicator, the MK2430 also supports parallel indication of several MK2430 in different
rooms.
In the event of an alarm message, the yellow LED "WARNING" resp. the red LED "ALARM"
lights up and the message appears on the LC display in plain text format. At the same
time there is an audible signal (acknowledgeable/can be muted. If a second message is

System description
15
MK2430_D00129_00_M_XXEN/12.2014
received whilst the first is still pending, the audible signal will sound again and the
messages appear alternately on the LC display. The address of the device triggering the
alarm can also be requested. The audible signal sounds again once a configurable
period of time has elapsed (repetition can be deactivated).
Internal device parameters (alarm addresses, test addresses…) and the parameteri-
sation of EDS- and RCMS systems can be accessed via the menu system.. MK2430 can be
used as a master device in installations with several IT and EDS systems.
The test button can be used to check the function of the associated devices such as
insulation monitoring devices, LIM (Line Isolation Monitors) or GFCI (Ground Fault
Circuit interrupters). The message is available on the MK2430 on which the test button
"TEST" was pressed. The test and its individual evaluations are carried out sequentially.
Finally, a message appears that the test was successful or a fault message will be output.
MK2430 features:
 Display of operating status, warning and alarm messages in accordance with
IEC 60364-7-710, DIN VDE 0100-710 and other standards
 Backlit clear LC text display (4 x 20 characters)
 Standard texts for messages in 20 national languages
 200 freely programmable message texts (with TMK-SET PC software)
 Bus technology for easy installation and reduced fire load
 Audible alarm (can be acknowledged or muted)

3.3 Function
3.3.1 Display/operating elements
The backlit display features four lines of 20 characters each. It supplies medical and
technical personnel with clear and unambiguous information, to help them make
decisions. Every alarm message comprises three lines which appear spontaneously and
three additional lines which can be displayed at the touch of a button. The fourth line
contains status information (i.e. number of messages, test procedures, menu infor-
mation). Three LEDs are located above the text display. They indicate:
Normal operation (green), warnings (yellow) or alarms (red).
Five buttons are available to acknowledge or to mute alarms and warnings and for
testing the assigned devices and for the menu system.
3.3.2 Programmable messages
Standard message texts can be activated by enabling alarm addresses. These texts are
available in 20 languages. Alarm addresses can be enabled via the device menu system
(without PC). Individual message texts, each comprising 6 lines of 20 characters can be
programmed with the TMK-SET PC software.
An LED (yellow or red) and an audible signal can be assigned to each message. For this
purpose, the PC is connected to the USB interface or BMS bus (RS-485).

System description
17
MK2430_D00129_00_M_XXEN/12.2014
3.3.3 History memory
Warnings and alarms are written to the history memory. 250 text messages can be
stored. Each subsequent message overwrites the oldest message in the history memory
(message 251 will overwrite message 1 etc.). The history memory can be read via the
operating menu or the TMK history PC software.
3.4 Versions
3.4.1 MK2430-12
The MK2430-12 is used for visual and audible indication of alarms from Bender's EDS,
RCMS and MEDICS systems®and for testing assigned devices (e.g. insulation monitoring
devices, LIM, GFCI). Furthermore, the MK2430-12 can be used as parallel indication in
conjunction with MK2430-11 and SMI472-12. The programmed message texts are
displayed on the LCD in the selected national language.
3.4.2 MK2430-11
The MK2430-11 features all the functions of the MK2430-12. In addition, the MK2430-11
provides 12 digital inputs and a programmable relay output. All digital inputs, divided
into three groups of 4, are electrically isolated from each other. The input voltage is
LOW = 0…2 V). In practice, these digital inputs (IN1… IN12) are controlled via potential-
free contacts (N/C or N/O operation configurable). The voltage required for these inputs
is provided via the power supply unit, which also supplies power to the MK2430. Any
message text can be assigned to the inputs.
3.4.3 MK2430P-…
The MK2430P-… contains the programming of the standard display and up to 20
factory-set alarm addresses can be activated. A line containing a note about the
assigned equipment can be programmed individually for each alarm address. This line
appears as the first line in an alarm.
For many applications with medical IT systems, this programming scope is sufficient. A
programming template in the shape of a form is available for customer-specific
programming.
Up to 200 individual alarms can be programmed in the factory subject to an additional
fee. This type of programming is recommended for EDS, RCMS, medical gases or BSV
systems.

System description

3.4.4 Interfaces
MK2430 feature a BMS bus and USB interface.
3.4.4.1 BMS bus
The BMS bus is used for communication with BMS bus nodes.
– such as UMC…, UMA…, UFA…, UFC…, LFC… modules
– or devices like RCMS…, EDS…, SMI…, SMO…, ATICS®,
alarm indicator and operator panels.
The MK2430 acts as the master whenever the address is set to 1 and as a slave for
address setting between 2 and150.
The Master is responsible for specific tasks:
– As a "master clock", it synchronises the time of all devices on the internal BMS
bus;
– it controls the data traffic on the BMS bus.
3.4.4.2 USB interface
A PC can also be connected to the MK2430 via the USB interface with a USB cable (Type
A plug onto Type B plug). To access the interface, the MK2430 has to be removed.
Only the connected MK2430 can be read out and set via the USB interface.
Programming and reading the MK2430
Connect the MK2430 to a PC:
 directly via the USB interface or
 via an RS-232/RS-485 converter DI-2 or
a USB/RS-485 converter DI-2USB to the BMS bus.
You can use the optional TMK-SET PC software to display and change the MK2430 set-
tings.
The optional PC software TMK history can be used to read out the MK2430.
