Testing the signal technology
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

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18.
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.
Instruction:
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

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
cables (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
transmission and under some circumstances can destroy electronic
components.
