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 availability 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
14
MK800_D00053_00_M_XXEN/07.2015
System description
time there is an audible signal (can be acknowledged/muted). If a second message is received whilst the first is still pending, the audible signal will sound again and the messages 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 configurable 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 Circuit 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.

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 information). 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).

MK800_D00053_00_M_XXEN/07.2015
System description
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
vices, LIM, GFCI). Furthermore, the MK800-12 can be used as parallel indication in conjunction 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 practice, 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.

and a USB interface.
MK800_D00053_00_M_XXEN/07.2015
17
System description
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 panels, 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 settings.
The optional PC software TMK history can be used to read out the MK800.

Connect the internal and external BMS bus according to the instructions in the "BMS
bus" leaflet.
Use a shielded and twisted cable with a diameter of at least 0.8 mm for the interface
line (e.g. J-Y(St)Y n x 2 x 0.8). The shield must be connected to earth at one end. Please
note that, when routing the supply voltage
Us, a 4-wire cable (2 x BUS, 2 x
Us) with suit-
able cross section is required.
Use the DIP switches S1 and S2 to set the terminating resistor for the internal and
external BMS bus: S1 = external BMS bus; S2 = internal BMS bus. Factory setting
S1 and S2: off.
MK800-11 only: Use cables with a cross section of at least 0.75 mm
2
when connecting the digital inputs and the relay output. The maximum cable length per
connection is 500 m.

Installation and connection
Legend to wiring diagram
1 Supply voltage US (see „Technical data“ on page 83.)
Note: Make sure that the power supply of the MK800 is isolated from PE.
If this is not taken into account and a personal computer is connected to
the USB interface, the MK800 device and the PC may be damaged.
In MK800AF only: Connect aluminium front panel to the protective conductor (PE).
2 Looped through connection for supply voltage (e.g. for control voltage relay
contacts)
3 Switch S1 to terminate the external BMS bus.
If two or more devices are connected to each other via the BMS bus, the bus
line must be terminated at both ends with a resistor (R = 120 Ω).
4 External BMS bus connection. The external BMS bus is primarily used for the
connection of several MK800 or TM800. SMI472-12 signal converters can also
be connected.
5 Internal BMS bus connection. Various Bender devices with a BMS bus inter-
face can be connected to the BMS bus. These may include: Insulation monitoring devices 107TD47, control devices PRC487, residual current monitors
RCMS470 and many more.
6 Switch S2 to terminate the internal BMS bus.
If two or more devices are connected to each other via the BMS bus, the bus
line must be terminated at both ends with a resistor (R = 120 Ω).
7 USB interface. For PC connection. The TMK-SET PC software is used to pro-
gram the MK800. You can use the PC software TMK-HISTORY to read out the
MK800 history memory.
8 MK800-11 only: Digital inputs. The digital inputs can be controlled by an
internal or external voltage and potential-free contacts. If the inputs are controlled via an external voltage, the common 0(-) is applied to terminal "0 V"
and the 1(+) signal to the corresponding input IN1…IN16.
9 MK800-11 only: Relay output. Programmable contact for device errors, test of
assigned devices, device failure, common alarm message, buzzer
