2 Safety notes
2.1 Representation
At various points in this manual you will see notes and precautionary warnings
regarding possible hazards. The symbols used have the following meaning:
DANGER!
●indicates an imminently hazardous situation which will result in death or
serious bodily injury if the corresponding precautions are not taken.
WARNING!
●indicates a potentially hazardous situation which can result in death or se-
rious bodily injury if the corresponding precautions are not taken.
CAUTION!
●meansthat ifthe corresponding safetymeasures arenottaken, apotentially
hazardous situation can occur that may result in property injury or slight
bodily injury.
CAUTION
●CAUTION used without the safety alert symbol indicates a potentially haz-
ardous situation which, if not avoided, may result in damage to property.
●This symbol reminds you of the possible consequences of touching elec-
trostatically sensitive components.
Information
Useful practical tips and information on the use of equipment are identified
by the “Information” symbol. They do not contain any information that warns
about potentially dangerous or harmful functions.
2.2 General safety instructions
WARNING!
●It is absolutely essential to observe the safety instructions in the system
manual.
●The module is defined as "open type equipment" (UL508) or as "offenes
Betriebsmittel" (EN 61131-2) and must therefore be installed in a control
cabinet.

Project engineering manual 1.04 9

CAUTION
Improper use of the assembly or the control system leads to irreparable dam-
age!
●Turn off the power supply before inserting or removing the module. Other-
wise, the module can be destroyed or undefined signal states can lead to
damage of the control system.

2... 2 encoder inputs
Information
●The incremental interface module MM 280/A is not designed for drive
control.
●The type plate is stored on the module in an EEPROM and can be read
out by the application.

3.2 Accessories
3.2.1 Connector strip
Input-/output signals: Standard male connectors with grid dimension 5.08 mm
The following female connectors can be used for the MM 280/A:
Female connector Color Order no. Weidmüller
2-pole sw BLZF 5.08/2 SN SW - 170769
4-pole sw BLZF 5.08/4 SN SW - 170771
6-pole sw BLZF 5.08/6 SN SW - 170773
8-pole sw BLZF 5.08/8 SN SW - 170775
Information
Larger terminal blocks may be used to group multiple signals. The current
carrying capacity of the terminal block is thus, however, reduced (according
to derating curve of the terminal block manufacturer.)
The appropriate female connectors are not included in the delivery of KEBA,
but can be purchased from KEBA.
The technical data for the terminals are contained in the technical data sheet
of the manufacturer of the female connectors.
For further information see System manual.

4 Connections and wiring
4.1 Power supply
WARNING!
Danger of personal injury due to electric shock!
●Supply the device exclusively from power sources that have an extra low
voltage (e.g. SELV or PELV according to EN 61131-2)
●Connect only voltages and power circuits to connections, terminals and
interfaces up to 50 V rated voltage that have a secure disconnect for haz-
ardous voltages (e.g. with sufficient isolation).
CAUTION!
Fire hazard during module failure!
●Providesuitable fusesfor the24 VDC powersupply forthe finalapplication.
Only fuses with a maximum nominal disconnecting current of 10 A may be
used.

●To run the rotary encoders, it is necessary to supply the MM 280/A via
the terminals 0 V and 24 V.
Power supply is via the 24 V terminal at the front. The 24 V are looped through
secured. In addition, 5 V are generated internally from the 24 V. The 5 V trans-
ducer supply can carry loads of up to 100 mA each.

5 Configuration
General information
A Kemro system needs data for the configuration of system performance, its
I/O-devices and interfaces. The system reads this data during the start-up op-
eration and allocates them to its components and devices.
Configuration data is created by included configuration tools or by editing con-
figuration files.
For further information to the configuration see the documentation of the in-
cluded configuration tool.
For further information to the configuration see the documentation of the in-
cluded configuration tool.
5.1 Setting the K-Bus address
The module is addressed via the address switch.
The number of modules that can be added on is limited as follows:
●8 pieces MM 280/A to a CPU module (permitted address switch positions
0 - 7).
●5 pieces MM 280/A to a bus link module BL 250/A (permitted address
switch positions 0 - 4).
●2 pieces MM 280/A to a bus link module BL 210/A (permitted address
switch positions 0, 1).
Theaddress switch is located onthe right side underneath thelowercover (the
K-Bus plug is located underneath the upper cover).
Fig.5-1: Position of the address switch
1... Address switch
On leaving the factory all modules are set to address 0 and both covers are
closed.
Configuration MM 280/A

Project engineering manual 1.0418

Information
Modules of the same type that are installed within the same line must have
different address switch positions. Different modules (e.g.: AI 240/A and DI
260/A) may have the same address switch positions.
The two covers for the K-Bus plug and the address switch must remain locked
at the last module in the line (to protect against dirt and damage through elec-
trostatic discharge on contact).
