1. Product description
The RLAnet monitoring device is a component of the BARTEC
water detection system and is used to detect electrically
conductive and non-electrically conductive liquids.
Together with the SCR sensor line and the PS point sensor, the
RLAnet monitoring device can detect electrically conductive
liquids, together with the PSO/PSO+ point sensor, electrically
non-conductive liquids can be detected.
The system quickly and reliably detects smaller leaks and
generates an optical and acoustic warning signal. The floating
contact is switched at the same time to forward the signal to the
PLC or a building management system.
With the integrated software of the RLAnet monitoring device, it is
possible to establish an exact localisation of the leak that has
occurred. The leakage is determined with an accuracy of one
meter and shown on the four-digit display.
The speed at which a leak is detected depends on the volume
and conductivity of the leaked liquid. The SCR sensor line
achieves the shortest response time when it is completely
surrounded by water (approx. 5 mm water level) or when it is
surrounded by a sensor line length of at least 20 cm. Due to its
geometry, a minimum amount of leaking liquid is required for
detection by the point sensor PS or PSO/PSO+. See the point
sensor data sheet for more information.

2. Safety regulations
The RLAnet monitoring device is state-of-the-art and reliable. In
order to ensure safe operation, careful system planning, proper
transport, professional assembly, commissioning and
maintenance of all components used is required.
RLAnet may only be operated and used in accordance with its
intended use in compliance with these assembly and operating
instructions, the applicable national standards, regulations and
approvals (e.g. directives 2014/30/EU, DIN VDE series 0100).
Improper use or handling of the product can result in serious
personal injury or death. This can also damage the product, the
system and the environment.
BARTEC GmbH assumes no liability for damages resulting from
the installation and use of the software, and in particular not for
personal injuries and property damages as well as financial
losses that are directly or indirectly associated with the use of the
software.
Please read carefully through these assembly and operating
instructions in full before you carry out any work on the RLAnet or
the system. The instructions and warnings included in these
assembly and operating instructions must be read, understood
and observed.
Keep the manual near the RLAnet monitoring device for future
reference and pass it on to new owners where relevant.
Product specifications are subject to change without prior notice.
Claims for damages resulting from changes, errors or misprints
are excluded.
2.1. Intended use
The RLAnet monitoring device is used to detect and localise
electrically conductive and non-electrically conductive liquids. It is
intended for the use outside of potentially explosive atmospheres.
The RLAnet monitoring device is intended for operation with a
suitable control line or the SCR sensor line and the PS point
sensor or the PSO/PSO+ point sensor.
Before start-up, the parameters set on the monitoring device must
be compared with the actually required parameters of the system
and corrected if necessary. Set parameters must match the
installed components of the system.
All system components may only be operated as intended and
within their specifications (technical data). The applicable national
installation regulations must be observed.
The information in these assembly and operating instructions for
the respective life phases must be observed and complied with.

6Assembly and operating instructions / EN
2.2. Foreseeable misuse
The use of the RLAnet monitoring device is not permitted:
–outside of its intended use
–with non-approved or unintended components
–in potentially explosive areas
–outside of its specifications (technical data)
–the technical modification or opening of the component
–without observing the information in the assembly and
operating instructions and applicable national installation
regulations
2.3. Personnel qualifications
Only trained personnel may use the RLAnet monitoring device.
The personnel must have basic electrical knowledge.
The wiring for electrical installations and, if necessary, for
maintenance or changes to the installed system may only be
carried out by a qualified electrician.
Decommissioning and dismantling may only be carried out by
trained persons. Disposal is only permitted through an approved
specialist company.
2.4. Symbols and signs
The warnings shall be intended to protect against dangerous
situations, personal injury and damage to property.
In the operating instructions, the severity of the possible dangers
is indicated by the following signal words.
DANGER!
DANGER indicates an imminent danger. If not
avoided, death or serious injury will result.
WARNING!
WARNING indicates a potentially imminent danger.
If not avoided, it can result in death or serious injury.
CAUTION!
CAUTION indicates a potentially imminent danger. If
not avoided, minor injuries may result.
ATTENTION!
ATTENTION indicates a potentially harmful
situation. If not avoided, the plant or something in its
vicinity may be damaged.
PLEASE NOTE!
PLEASE NOTE indicates notes and information on
an effective, economical and environmentally
friendly handling.
