medical locations.
Example of a section of a hospital with the MEDICS® system:
TGH1389en/08.2012 13
System description
Legend to example
MK2430 Alarm indicator and test combination
RCMS Residual current monitoring system for TN-S systems
SMI472 Signal converter for third-party systems (e.g. med. gases, BSV sys-
tems)
TM Alarm indicator and operator panel
UFC107E… Changeover and monitoring module for IT systems with EDS… in-
sulation 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 distri-
bution boards)
MEDICS® includes:
  Display and operating units such as TM…operator panels or MK… alarm indicator
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 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 of the instal-
lation for the user.
3.2 Features
On its backlit LC 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 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
time there is an audible signal (acknowledgeable/can be switched to mute). If a second
message is received whilst the first is still pending, the audible signal will sound again
14 TGH1389en/08.2012
System description
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 (repetition can be deactivated).
Internal device parameters (alarm addresses, test addresses,…) and the parameter
setting for EDS and RCM systems can be accessed via the menu system. As a master, the
MK2430 can also be used as master device in installations with a number of IT and EDS
systems.
The test button can be used to check the operation of the associated devices (e.g.
insulation monitoring devices, LIM (Line Isolation Monitors) or GFCI (Ground Fault
Circuit Interrupters). A message is output only on the MK2430 on which the test button
"TEST" 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.
MK2430 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

System description
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 unambiguous, in order to help them
to make decisions. Every alarm message comprises three lines which appear spontane-
ously and three additional lines which can be displayed at the touch of a button. The
fourth line contains status information (number of messages, test procedures, menu
information). Three LEDs are located above the text display. They indicate:
Normal operation (green), warnings (yellow) or alarms (red).
Five buttons are available for acknowledging or setting alarms to mute and warnings,
for testing the associated devices 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 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 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).
16 TGH1389en/08.2012
System description
3.3.3 History memory

Warnings and alarms are written to the history memory automatically with date and
time stamp. 250 text messages can be saved. After this, each subsequent message then
overwrites the oldest message in the history memory (message 251 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 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 also be used as parallel indication
in conjunction with MK2430-11 resp. SMI472-12. The programmed message texts are
displayed on the LCD in the selected language.
3.4.2 MK2430-11
The MK2430-11 features all the functions of the MK2430-12 plus 12 digital inputs and a
programmable relay output. All digital inputs are electrically isolated in three groups of
4. 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… 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 the factory
activation of up to 20 alarm addresses. 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.
Furthermore, 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.
TGH1389en/08.2012 17
System description
3.4.4 Interfaces
MK2430 feature a BMS bus and USB interface.
3.4.4.1 BMS bus

The internal BMS bus is used for communication with MEDICS® components,
– e.g. modules such as UMC…, UMA…, UFA…, UFC…, LFC..
– or devices like RCMS…, EDS…, SMI…, SMO…, ATICS®, alarm indicator and
operator panels.
The MK2430 is the master whenever the address is set to 1. An address setting of 2…150
denotes operation as a slave.
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.
In order to program the MK2430, a PC must be connected

– to the BMS bus either via an RS-232/RS-485 adapter
– or to a USB/RS-485 adapter.
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). The interface can only be accessed when the MK2430 has
been removed.
Only the connected MK2430 can be read out and set via the USB interface.
Optional software
  You can use the the TMK-SET PC software to display and change the MK2430
settings.
  You can use the PC software TMK-HISTORY to read out the MK2430 history
memory.

4.2 Connections
Risk of electric shock!
Before fitting the enclosure and working on the device connections,
make sure that the power supply has been disconnected and the sys-
tem is dead.
Failure to comply with this requirement will expose personnel to the
risk of electric shock. Furthermore, the electrical installation may sus-
tain damage and the device may be destroyed beyond repair.
You must only connect the MK2430 as illustrated in the diagram in
this chapter. Do not make any changes to the internal wiring.
Non-compliant connection or arbitrary changes can lead to serious
malfunctions or even the complete failure of the MK2430.
The device contains components that can be damaged by electro-
static discharges (ESD). When work activities are carried out at the
opened device, the safety precautions for the dissipation of electro-
static electricity have to be observed..
4.2.1 Notes on connection

  Connect the MK2430 to the supply voltage (terminals U2/V2).
– If you are connecting the MK2430 to a DC 24 V supply: take the line voltage
drop into account if you are using long supply cables for the supply voltage.
– Consider the maximum permissible cable lengths for the supply voltage U2/V2
when using an AN450 or AN410 power supply unit (refer to "Technical data" ).
  The connection to the internal BMS bus is made via the terminals A/B. Connect
the BMS bus as described on the "BMS bus" instruction leaflet. Use a shielded
cable of at least mm or 0.8 mm cross section for the interface line (e.g. J-Y(St)Y n x
2 x 0.8). Connect the shield to PE at one end. When wiring the bus connection,
please note that a 4-wire cable (2 x BUS, 2 x US) with suitable cross section is
required when routing the supply voltage Us.
  Set the terminating resistor for the BMS bus on the "Term" DIP switch. Factory set-
ting: off.
  MK2430-11 only: Use cables with a cross section of at least 0.75 mm
2 when con-
necting the digital inputs and the relay output. The maximum cable length per
connection is 500 m.

During the test, the text "TEST" will appear in the status bar. "TEST" flashes if the
message on the display is associated with the test.
The assigned devices are tested one after the other. The MK2430 automatically
evaluates the messages that appear. Once the process is complete, either a common
message indicating that the test has been successful or an error message is output.
If more than one device has been tested, a separate error code will be displayed for each
device failing the test.

Notes about error codes

  For MK2430 operating as "slaves" on the BMS bus, a time-out of 50 seconds is
applicable for error codes 0 and 14.

  Error code 14 is displayed if the test has been requested on a slave but the test
command cannot be sent because the MK2430 was not scanned. This can be the
case if the address gap upstream of the MK2430 is so large that the master does
not scan the MK2430 (refer to "BMS bus" operating manual). This error code is less
of an indicator that an ISOMETER® is faulty and much more of an indicator of a
fault on the BMS bus system.

The "History" menu provides information about messages, acknowledgements and
associated times. It also indicates whether an alarm is still pending or when it was
acknowledged / set to mute with the " Mute" button. The complete content of the
history memory with additional texts and address of the device sending the message
can be displayed on a PC and printed out using the TMK-HISTORY software version V3
or higher. All interfaces of MK2430 can be used for connection.

Digital input alarm texts

A neutral or specific alarm message can be assigned to all digital inputs. A neutral alarm
message indicates the alarm, the channel and the address of the device triggering the
alarm. In comparison, specific alarm messages (medical) signal non-modifiable pre-
programmed alarms, e.g. "oxygen".
Assign the inputs in accordance with table "neutral and specific alarm messages" on
page 61.
Other messages can be assigned to individual or all digital inputs with the TMK-SET PC
software.
If freely programmable alarm messages need to be displayed on a different MK2430 or
an alarm indicator and operator panel, the same alarm messages must have been
programmed in the displaying device.
The alarm messages in the following table are sent to other MK… or alarm indicator and
operator panels via BMS bus and displayed there in plain text format.
60 TGH1389en/08.2012
Specific alarm messages

These messages contain instructions for medical gases and UPS systems.
Alarm messages for medical gases are signalled by the red "ALARM"
LED and the buzzer sounding. The buzzer can be set to mute (ac-
knowledged). It will sound again after 15 minutes by way of remind-
er.
Non-standard settings can only be made using the TMK-SET soft-
ware.
