bution boards)
ZLT Central Control Technology
GLT Building Control Systems
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. MEDICS®system modules are, for
example: UMC…, USC…, UFC… as well as 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®is to be found in communication between all involved
components and the resulting information provided to the user. The functionality of
the equipment is continuously monitored. Operating states, irregularities, faults and
equipment failures are displayed. This means high operational reliability and high avail-
ability of the installation for the user.
3.2 Characteristics
On its backlit display (4 x 20 characters), the MK800 displays messages from all BMS bus
devices assigned via alarm addresses. As well as being used as a standalone indicator,
the MK800 can also be used as parallel indication of several MK800 in different rooms.
In the event of an alarm message, the yellow "WARNING" LED or the red "ALARM" LED
lights up and the message appears on the LC display in plain text format. At the same

System description
15
MK800_D00053_00_M_XXEN/07.2015
time there is an audible signal (can be acknowledged/muted). If a second message is re-
ceived whilst the first is still pending, the audible signal will sound again and the mes-
sages will appear alternately on the LC display. In addition, the address of the device
triggering the alarm can be called up. The audible signal sounds again once a config-
urable period of time has elapsed (repetition can be deactivated).
Internal device parameters (alarm addresses, test addresses…) and also the parameter
setting of EDS and RCMS systems can be accessed via the menu system. MK800 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 Cir-
cuit interrupters). The message is only available on the MK800 on which the button
"TEST" was pressed. The test and its individual evaluations are carried out sequentially.
Finally a message appears indicating either a successful test or a fault.
MK800 feature:
 Display of operating status, warning and alarm messages in accordance with
DIN VDE 0100-710, IEC 60364-7-710 and other standards
 Backlit clear LC text display (4 x 20 characters)
 Standard texts for messages selectable in 21 national languages
 1000 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)
 Menu-based setting (German/English): MK800 basic parameters
and via BMS bus: EDS46x, EDS47x, EDS49x, RCMS460, RCMS470, RCMS490
 Types available for flush and surface mounting
 Easy commissioning due to predefined alarm text messages
 16 digital inputs (MK800-11 only)
 History memory with real-time clock to store 1000 warning and alarm messages

3.3 Functionality
3.3.1 Display/operating elements
The backlit display features 4 lines of 20 characters each. It assists medical and technical
personnel during the decision-making process with information that is always clear and
unambiguous. 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 (the number of messages, test procedures, menu infor-
mation). Below the text display, three LEDs are arranged. They indicate:
Normal operation (green), warnings (yellow) or alarms (red).
Five buttons are available to acknowledge or to mute alarm and warning messages, 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 21 national languages. Alarm addresses can be enabled via the device
menu system (without personal computer). Individual message texts each comprising
6 lines à 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).

3.3.3 History memory
Warnings and alarms are automatically written to the history memory with date and
time stamp. 1000 text messages can be stored. Each subsequent message overwrites
the oldest message (message 1001 will overwrite message 1 etc.). The history memory
can be read out via the operating menu or the TMK-history PC software.
3.4 Versions
3.4.1 MK800-12
The MK800-12 is used for visual and audible indication of alarms from Bender EDS,
RCMS and MEDICS®systems and for testing assigned devices (insulation monitoring de-
vices, LIM, GFCI). Furthermore, the MK800-12 can be used as parallel indication in con-
junction with MK800-11 and SMI472-12. The programmed message texts are displayed
on the LCD in the selected national language.
3.4.2 MK800-11
The MK800-11 features all the functions of the MK800-12. In addition, the MK800-11
provides 16 digital inputs and a programmable relay output.
All digital inputs, divided into four groups of 4, are galvanically isolated from each other.
The input voltage is AC/DC 10…30 V/2…5 mA (HIGH = 10…30 V; LOW=0…2 V). In prac-
tice, these digital inputs (IN1…IN16) are controlled via an internal or external voltage
and 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
MK800. Any message text can be assigned to the inputs.
3.4.3 Interfaces
MK800 feature
 an internal BMS bus,
 an external BMS bus
 and a USB interface.

System description
18 MK800_D00053_00_M_XXEN/07.2015
3.4.3.1 Internal BMS bus
The internal BMS bus is used for communication with BMS bus devices,
– e.g. modules like UMC…, UMA… , UFA…, UFC…, LFC…, ATICS
– or devices like RCMS…, EDS…, SMI…, SMO…, alarm indicator and operator
panels
The MK800 is the master whenever the address is set to 1.
An address setting of 2…150 denotes operation as a slave. This setting is only possible
when the external BMS bus is disconnected.
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.
3.4.3.2 External BMS bus
The external BMS bus is used as a coupling between alarm indicator and operator pan-
els, MK800 and central data recording devices via SMI472-12.
The device with address 1 (master) synchronises the time of all devices on the external
BMS bus as "master clock".
The master function is cyclically passed starting from address 1.
3.4.3.3 USB interface
A PC can also be connected to the MK800 via the USB interface with a USB cable (Type
A plug onto Type B plug).To access the interface, the MK800 has to be removed.
Only the connected MK800 can be read out and set via the USB interface.
Programming and reading the MK800
Connect the MK800 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
internal or external BMS bus.
You can use the optional TMK-SET PC software to display and change the MK800 set-
tings.
The optional PC software TMK history can be used to read out the MK800.
