1 Preliminary remark
These instructions explain the basics of dimensioning, laying and terminating of the cables as well as the
procedure of commissioning of the Gas Controller system DGC- 05.
These data were compiled by us with great care, but deviations are possible. Therefore we shall not be liable for
possible mistakes in this description.
At commissioning the technical requirements and regulations concerning wiring, electrical security, environmental
conditions, fire protection etc. must be considered on site.
2 Introduction
For simple and fast installation of the field bus cable, the DGC- 05 system is solely geared to the Twisted Pair
Cable JY(St)Y 2x2x0,8LG concerning communication, operating voltage supply, connecting etc.. For this cable
you have to consider the following when dimensioning and installing:
Bus installation
Physical load capacity.
3 Installation of field bus cable
The installation of the field bus cable to the bus transmitters DT- 05 has to be executed only in line topology.
Branch lines are not allowed. For reliable communication the cable length shall not exceed 900 m per network
segment. The cable length is also limited essentially by the physical load capacity. Section 3.4 gives examples for
the cable lengths in dependence of the connected DT- 05, they must be adhered to in any case. Max. 24 DT- 05
may be connected per bus segment.

3.1 Application of repeaters
Networks of larger dimensions are divided into several network segments. Each supplementary network segment
permits the installation of 24 additional DT- 05 transmitters. The maximum cable lengths apply to one network
segment each. Repeaters are used for connecting the segments.
Repeaters amplify the data signals, but do not reproduce them, therefore maximum 3 repeaters per system are
allowable.
Repeaters can be installed both in the DGC-05 central unit and in the field.

3.2 Termination
Each segment needs a ohmic terminating resistor of 560 Ohm at each of the both cable ends.
These terminating resistors are already integrated in the DGC- 05 system. If the bus wiring is executed according
to our guidelines including return of each bus cable to the DGC- 05 central control, no other actions will be
necessary for terminating.
For individual termination of the bus the terminating resistor can be activated or deactivated at the repeater REP-
05 and at the bus connector BC- 05. Alternatively a resistance of 560 Ohm can be connected at the bus end
between the bus lines BUS_A and BUS_B. Please check that only one resistance is active at each bus end!

3.3 Physical load capacity of the bus cable
The DT-05 transmitters work with a nominal operating voltage of 24 VDC. This tension is impressed via the shared
4-wire Twisted Pair Cable (JY(St)Y 2x2x0,8LG) with a cross-section of 0,5 mm2.
Therefore you have to calculate which cable length is allowable in dependence of the total power of the connected
DT- 05 / AT transmitters, in order to obtain the required minimum terminal voltage of 15 VDC at all of the DT- 05 /
AT transmitters.
Note:
The operating voltage supply of the EP- 05 modules mounted in the field always shall be executed via a separate
line, because due to the higher power requirement of the modules the allowable voltage drop in the bus cable only
permits relatively short cable lengths.
3.4 Calculation of the cable length
As described above, the field bus cable is only laid in line topology. There are three possibilities for a voltage drop
in the bus cable:
a. No return line of the cable
b. Return line of the cable
c. Parallel laying of the cable with a higher cross-section.
For calculating the permissible cable length an Excel program is available.
For fast projection some examples related to practice are calculated for the three possibilities concerning
maximum lengths of feed line cables and intermediate cables.

4 Mounting / Electrical Connection
The Gas Controller is fixed to the wall through the marked mounting holes at the back side of the housing. These
mounting holes are accessible after opening the housing. (Plastic enclosure)
The mounting holes are covered with the enclosed caps after the end of the assembly. (Plastic enclosure)
We recommend to consider the following when choosing the mounting position.
• Location of the Gas Controller must conform to the layout of the area being monitored.
• Avoid locations where water, oil etc. may influence proper operation and where mechanical damage might
be possible.
• Cables are introduced from top and/r bottom side.
• Keep at least 150 mm distance on the left side to open the door.
• Obey customer’s instructions.
4.1 Electrical Connection
The technical requirements and regulations for wiring, electrical security, as well as project specific and
environmental conditions etc. must be observed when mounting.
We recommend the following cable typs:1
• Power supply NYM-J 3 x 1,5 mm2
• Alarm Relay NYM-J X x 1,5 mm2
• Bus JY(St)Y 2x2x0,8LG
1The recommendation does not consider local conditions such as fire protection etc..
The alarms are also connected directly to the module by terminals. The terminals of the alarm relays have 2
contacts each for transmitting the signals.
The alarms are available as SPDT, potenialfree contacts.
For the exact position of the terminal s of the alarm relays see the following connection diagram.

5 Commissioning
For fast and comfortable commissioning we recommend to proceed as follows. Especially the given specifications
of the field bus cable have to be checked carefully, because it is here where most of the causes for problems of
the field bus communication appear.
5.1 Optical check
• Right cable type used.
• Cable topology and cable length.
• Correct connection at each bus transmitter according to the following figure.
• Termination at the beginning and at the end of each segment.
• Pay special attention to the fact that the polarity of BUS_A and BUS_B is not reversed!

5.2 Check short-circuit / interruption / cable length of the bus leads
This procedure has to be executed for each single segment.
Disconnect the bus leads from pin 3 and pin 4 of the DGC- 05 central control.
Connect ohmmeter to the loose leads and measure the total loop resistance.
See fig. 15 Loop resistance.
The total loop resistance is calculated as follows:
R (total) = R (cable) + 560 Ohm (terminating resistance)
R (cable) = 71 Ohm / km (loop resistance) (JY(St)Y 2x2x0,8LG)
R(total) = < 560 Ohm Short-circuit Look for short-circuit in the field
R(total) =infinite Cable interruption Look for cable interruption in the field
R (total) = > 560 Ohm < 640 Ohm Cable is OK
The cable length can be calculated in a sufficiently exact way according to the following formula.
Total cable length (km) = (R (total) – 560 Ohm) / 71 Ohm
If the field bus cable is OK, reconnect it to the central control.

5.3 Check voltage and bus polarity of the field bus
• Plug-in transmitter boards of DT- 05 and AT 34XX.
• Switch-on operating voltage at the DGC- 05 central control.
• Check operating voltage and bus polarity at each DT- 05.
U min = 15 VDC!
• Bus polarity:
Measure tension BUS_A against GND and BUS_B against GND.
U BUS_A ca. 0,5 V > U BUS_B
U BUS = ca. 2 – 4 VDC (depending on the number of DT-05 and on the cable length)

5.4 Addressing DT- 05 transmitters
After having checked the field bus successfully, you have to assign a measuring point (MP) address to each DT-
05 transmitter.
The addressing is effected by the service tool DGC-05-STL in the menu “Addressing” directly at each DT- 05.
The service tool communicates not only with the DT- 05, but always via the GC- 05 to the DT- 05, too. Therefore
addressing is only possible when the GC- 05 is ready for use and the field bus is functioning.
The status LED of the DT- 05 is weakly illuminated when the operating voltage is active (voltage indicator)
An automatic link connection STL <> GC-05 <> DT-05 is established by connecting the DCG-05- STL to the
service tool jack of the DT- 05.
If this connection is OK, than you can read the actual DT- 05 address in the menu „Address“.
0 = Address of new DT- 05
XX = Actual DT- 05 Address
255 = Communication error! See 5.5
Addressing according to the following description:
Starting menu
Address DT-05
0 = DT- 05 has no address yet (delivery status DT- 05),
communication to the GC- 05 is OK, addressing possible.
XX = DT- 05 has already an address. Address can be changed.
255 = DT- 05 has no communication to the GC- 05 Controller (Central
control) addressing not possible, eliminate communication error.
Cursor is faded in, by using enter desired address.
Takes over entered address in the service tool.
The previous address is displayed again for one measuring cycle,
afterwards the assigned address is taken over by the DT- 05.
Addressing DT- 05 finished.
Unplug service tool.

The measuring point (MP) is activated automatically at the GC- 05 by addressing the DT 05.
After successful addressing and registration the GC- 05 queries periodically the measuring point of the DT- 05.
The DT- 05 responds to every query of the GC- 05. This reply message is indicated by a blinking pulse of the
status LED at the DT- 05. The cycle time is about 2 to 6 sec. depending on the number of the connected bus
subscribers.
Note:
Due to the great flexibility of the DGC-05 system concerning addressing and configuration there is also the
possibility to assign a DT- 05 address several times. The DGC- 05 system, however, is not able to define the
repeatedly assigned addresses clearly. Therefore it is necessary after commissioning to check in the menu
“Measuring points” of the GC- 05, if all assigned addresses are activated.
5.5 Communication error
Communication errors at commissioning are nearly always due to mistakes in laying the cables, in connecting to
the terminals and in terminating. Therefore the following checks have to be executed:
• Bus line reconnected after measurement of the loop resistance?
• GC- 05 controller in operating mode.
• Check the operating voltage at the DT-05
(X4, Pin 1 + and Pin 2 -; U min = 15 VDC)
• Check communication at another DT- 05.
If communication OK here, exchange previous DT- 05.
• Check bus leads for short-circuit or interruption.
See 5.2
• Check polarity of the system bus (BUS_A – BUS_B).
See 5.3
• Check termination.
Terminating resistance of 560 Ohm at the beginning and at the end of the segment.
• Check cable topology and cable length.
Only line topology <> No branch lines !!
Cable length depending on the load. See 3.4

5.6 Commissioning of expansion modules EP- 05
Up to five expansion modules (EP- 05) with five alarm relays each can be connected via the RS- 485 bus. Each
connected EP- 05 expansion module is registered in the menu “System parameters”. To recognize the position of
the EP- 05 modules a module address is assigned to each module via the address switch.
The table shows the assignment of the relay numbers to the module addresses.
Module- Addr. Relay No. Analog
Outout No.
1 06 to 10 03 to 04
2 11 to 15 05 to 06
3 16 to 20 07 to 08
4 21 to 25 09 to 10
5 26 to 30 11 to 12
With the DGC- 05 systems by MSR-E, the complete configuration of the EP- 05 modules is already factory-set.
Configuration only is necessary with single modules or in case of retrofitting or exchange of a module.
The address switch is located behind the connecting plug X1. Unplug X1 for addressing.
5.7 Fitting of system parameters
At commissioning the alarm relays must be assigned to the alarms (thresholds) for each measuring point. For all
other parameters the values are deposited as defaults, which can be changed at any time if necessary.
