insulation fault location system
UMC107E... Changeover and monitoring module for IT systems
UMC710D... Changeover module for main distribution boards
USC710D... Control module for changeover modules (preferably in main
distribution boards)
MEDICS®features
 Display and control units, such as TM... operator panels or MK... alarm indica-
tor and test combinations
 Single and three-phase monitoring modules. Examples of modules in the
MEDICS® system include UMC..., USC..., UFC... and EDS.... insulation fault loca-
tion systems.
 Communication between these components takes place via the BMS bus
(two-wire connection).
 The connection of third-party systems by means of protocol converters (gate-
ways), 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.
Readiness for operation is monitored continuously. Operating states, irregu-
larities, faults and equipment failures are displayed. From the user's point of
view, this means high operational reliability.
3.2 Features
On its backlit LC 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 also supports parallel indication. 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 time there is an audible signal (acknowledgeable). If a second

System description
15
TGH1408en/07.2009
message is received whilst the first is still pending, the audible signal will
sound again and the messages will flash up alternately on the LC display. The
address of the device triggering the alarm can also be called up. The audible
signal sounds again once a configurable period of time has elapsed (repeti-
tion can be deactivated).
Internal device parameters (alarm addresses, test addresses, …) and the pa-
rameter setting for EDS and RCM systems can be accessed via the menu sys-
tem. As a master, the MK800 can also be used in installations with a number
of IT and EDS systems.
The test button can be used to check the operation of an A-ISOMETER®
107TD47 or IRDH.... A message is only output on the MK800 on which the
test button was pressed. The test and its individual evaluations are carried
out sequentially. Once the process is complete, a message indicating that the
test has been successful or a fault message is output.
MK800 features
 Display of operating status, warning and alarm messages in accordance with
IEC 60364-7-710:2002-11, DIN VDE 0100-710:2002-11 and other standards.

3.3 Functionality
3.3.1 Display/operating elements
The backlit display features four lines of 20 characters. It supplies medical
and technical personnel with information that is always clear and unambig-
uous, in order to help them to make decisions. Every alarm message com-
prises three lines which appear spontaneously and three additional lines
which can be displayed at the touch of a button. The 4th line contains status
information (number of messages, test procedures, menu information).
Three LEDs are located below the text display. They indicate:
Normal operation (green), warnings (yellow) or alarms (red).
Five buttons are available for acknowledging alarms and warnings, for the
A-ISOMETER®test and for the menu system.
3.3.2 Programming
Standard message texts can be activated by enabling alarm addresses. These
texts are available in 20 languages. Alarm addresses can be activated via the
device menu system (without PC). Individual message texts, each comprising
6 lines of 20 characters can be programmed with the TMK-SET software.
An LED (yellow or red) and an audible signal can be assigned to each mes-
sage. For this purpose, the PC is connected to the USB interface or BMS bus
(RS-485).

System description
17
TGH1408en/07.2009
3.3.3 History memory
Warnings and alarms are written to the history memory automatically with
date and time stamp. 1000 text messages can be saved. Each subsequent
message overwrites the oldest message (message 1001 overwrites message
1). 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 Bend-
er's EDS, RCMS and MEDICS®systems and to trigger the A-ISOMETER®test
function via the BMS bus. Furthermore, the MK800-12 can also be used as
parallel indication in conjunction with MK800-11. The programmed message
texts are displayed on the LCD in the selected language.
3.4.2 MK800-11
The MK800-11 features all the functions of the MK800-12 plus 16 digital in-
puts and a programmable relay output.
All digital inputs are electrically isolated in four groups of 4. The input volt-
age 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 potential free
contacts (N/C or N/O operation configurable). The voltage required for the
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 systems feature
 an internal BMS bus,
 an external BMS bus
 and a USB interface.

System description
18 TGH1408en/07.2009
3.4.3.1 Internal BMS bus
The internal BMS bus is used for communication with MEDICS
®
components,
– e.g. modules like UMC..., UFC..., LFC...
– 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 has been switched off before.
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 data traffic on the BMS bus.
3.4.3.2 External BMS bus
The external BMS bus is used for the coupling of alarm indicator and oper-
ator panels, MK800 and central data acquisition devices via SMI472-12.
The device with address 1 (master) synchronises as "master clock" the time
of all devices on the external BMS bus.
The master function will be cyclically passed on from address 1 to the next
higher one.
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). The interface can only be accessed
when the MK800 has been removed. Only the currently 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 adapter DI-2 or a USB/RS-485 adapter DI-2USB to the
internal or external BMS bus.
You can display and change the settings of the MK800 using the PC software
TMK-SET. You can read out the history memory of the MK800 using the PC
software TMK-HISTORY.
