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.
