operating manual. Signal words illustrate the gravity of possible injuries if
the risk is ignored:
Signal word Meaning
DANGER Refers to imminent danger. Ignoring this sign may
lead to death or the most serious injuries.

DANGER
Mortal danger from electric shock!
Improperly installed or damaged components in the electronics instal-
lation can cause injury.
ðEnsure that all work on the electrical installation is performed by a
qualified electrician.
ðEnsure that all work on the electrical installation is performed in a
de-energised state.
ðEnsure that the power supply is secured with a fault current protec-
tive circuit.
ðReplace damaged cables or components without delay.
7.1 Principles
Make sure that the installation location complies with the following re-
quirements:
nThe display is easily accessible and is visible.
nPlan to leave free space for the installation of the cable underneath
the device.You must be able to install the cable without kinking or
damage.
nMount the sensors 30 cm above the ground.
nCompliance with the permissible ambient temperatures (see section 5
“Technical data” on page10).
7.2 Installation on the wall

ment results.As a result,the control of connected devices can be faulty.
ðDo not route the connecting cable parallel to the mains and control
connections, and always with a clearance of at least 15cm. Lay
connection junctions at an angle of 90°.
ðUse a max. 50 m signal cable.
4. Shorten the connecting cable to the required length. Apply a wire end
sleeve to the end of every wire.
5. Open the device housing and lead the cable into the inside of the
housing through one of the cable screw connections on the under-
side of the housing.
6. Connect the three or five coloured wires onto the input circuit board
clamp block. Comply with Tab. 10 “Clamp connection of the input cir-
cuit board” on page14.

necting the sensor” on page14.
ü
The device is activated.
Perform the following steps:
1. In Menu 2, navigate to the “Sensors” tab under Inputs.
2. Select “Sensor 1” and press the “Test” button.
4The device checks whether the selected sensor has been connected
correctly and if not, issues an error message. In the case of an error
message, check the sensor connecting cable and whether the sen-
sor has been inserted in the sensor bracket completely.
3. Repeat step 2 for all sensors.
4. Check the configuration of the sensors using section 8.2.1.1 “Sen-
sors” on page19.
5. Test the functionality of the sensors and actors (e.g. signal lamps and
signal bugles) with test gas. Comply with the specifications of the
test gas operating instructions. The display must show an increase of
the gas concentration. Given correspondingly set limit values, it must
also trigger actors (such as the signal bugle).

relay, the alarm message must be confirmed directly on the device. The
bugle relay is especially suited for an alarm at the first limit value.

7.6.2 Output circuit board (relay and relay high current)
You can control signal technology (e.g. horns or signal lamps) with the re-
lay output circuit boards and the relay high current output circuit boards.
To this end, the device can be fitted with up to four relay output circuit
boards, which can be used for a pre-alarm and a master alarm respec-
tively.
Application example: You can evaluate sensors in two different rooms us-
ing two relay output circuit boards.

values individually.
PLEASE NOTE
Damage to the device!
The mains supply terminals at the input (terminals 44–52) may be
operated with a maximum continual load of 6 A.
ðWith higher electrical loads, the relays on the output circuit board
must be connected with a separate cable and provided with fuse
protection!

7.6.5 Testing the signal technology
i
Always inform the connected stations and departments before
triggering a test alarm.
The device enables you to test the correct connection of the signal tech-
nology. The test simulates an alarm and the connected signal technology
is activated.
Take the alarm chain into account before conducting the test and inform
any connection points or interrupt the alarm chain for the period of the
test.
Precondition for action:
ü
The signal technology was installed in accordance with section 7.6
“Connecting the signal technology” on page15.
ü
The device housing cover is closed.
ü
The voltage supply has been established and the device has been
switched on.
Perform the following steps:
1. In Menu 2, navigate to > Outputs > Test.
4You will now see all the outputs.
2. Select the outputs that you would like to test.
3. Press "Start”.
4The signal technology connected will now be activated as in the
case of an alarm.
ü
Signal technology tested.
7.7 Digital inputs
You can use up to 8 digital inputs to evaluate switching statuses and to
detect them as alarm message which are to be documented in the log-
files.
Further information about the settings of the digital inputs can be found in
section 8.2.1.3 “Digital” on page20.
7.8 RC protection for relay
When connecting to the relay, note that inductive loads must be sup-
pressed. If this is not possible, the relay contact on the device terminal
must be protected by an RC protective circuit / interference suppression
element.
If devices with inductive loads from a nominal current of 1 A are connect-
ed to a relay, the contacts in the relay may become bonded. Thus, the de-
vice will operate in an uncontrolled manner. To prevent bonding if the load
circuit suffers a short-circuit, the relays must be protected separately on
the maximum relay switching current.
Precondition for action:
ü
You would like to connect an inductive load to the relay.
Perform the following steps:
1. Switch off the device.
2. Clamp the interference suppression element parallel to the inductive
load.
3. Should it prove impossible to perform point 2, clamp the interference
suppression element parallel to the relay output.
ü
RC element clamped.
7.9 Connecting Ethernet
You can use the Ethernet connection for the following actions:
nReading/writing via Modbus TCP/IP protocol (PLC or Computer)
nAccess via web browser
nAccess via TFTP server
The device has a network input in the form of a M12x1 socket. The manu-
facturer offers different lengths of special twisted-pair network cables to
make the typical Ethernet RJ-45 plug connection. If you use third-party
cables, choose a Category 3 cable with an impedance of 100 Ω or above.

Installing a wired network
During installation, comply with the following points:
nThe Ethernet is cabled in a star topology. The maximum cable length
is 100 m.
nYou must route separately as a bundle the different categories of ca-
bles (e.g. power supply, data lines and sensitive lines for measuring
purposes). In this connection, cables should cross at an angle of 90°.
nThere must either be a minimum distance between the power cable
and data lines of 10 cm or you must install a partition or route the data
line in a metal pipe.
nOnly use screened cables and plug-in connectors.
nRoute copper wires outside cable support systems through plastic
pipes.
nTemperatures that are too high or too low result in lower mechanical
and electrical loading or lead to damage.
nData lines must only be subjected to a defined tensile load; otherwise,
the electrical or attenuation values can no longer be guaranteed.
nWhen pulling cables out of the cable drum, avoid looping or pulling
over sharp edges.
nWith copper wires, implement potential equalization; when doing this,
differentiate between hazardous and non-hazardous areas.
nElectrical, magnetic and electromagnetic fields affect signal transmis-
sion and under some circumstances can destroy electronic compo-
nents.

2. In the “Horn” tab, configure the output and state the following infor-
mation.
3. In the event of an alarm: Select between "Relay on" or "Relay off".
4. Latching: On = The alarm is active, until it is manually confirmed. OFF

8.2.2.3 Digital output signals
You can control the connected signal technology with digital output sig-
nals. Only output 3 and output 4 are freely-configurable.

mation.

8.2.2.4 Analogue output signals
You can issue the sensor values via analogue signals and arrange for their
external evaluation.
Perform the following steps:
1. In Menu 2, navigate to the “Analogue” tab under Outputs.

formation.
3. 20 mA type: Configure the signal. The configuration required depends

5. Minimum: Establish the sensor value at which the signal should be at
its lowest.
6. Maximum: Establish the sensor value at which the signal should be
at its highest.
i
The values for “minimum” and “maximum” serve the scaling
of the analogue output signal. Example: Sensor 1 has a meas-
uring range of 0 – 10 ppm. 4 – 20 mA was selected as the 20
mA type. If the complete sensor measuring range is to be cov-
ered by the analogue signal, 0 ppm should be selected for
“Minimum” and 10 ppm for “Maximum”. At 0 ppm, a 4 mA
signal will be issued; at 10 ppm a 20 mA signal will be issued.
