Operating Instructions RDW 03 Monitoring Electronics M
The system quickly and reliably detects even small
liquid leakages. It transmits a warning in form of an
acoustic and optical alarm signal. At the same time,
floating contacts take care of the transfer of corre-
sponding messages to the building management
and control system.
The system is equipped with
• Electronic monitoring system
• Point sensor/sensor cable
• Accessories
Applications
Computer centers, ultraclean rooms, libraries,
banks, insurance companies, public buildings
The contact overviews shown for the “break” and “alarm” relays under terminal assignment in the
documentation for the connected RDW 03 are depicted with the following status:
RDW 03 to voltage – sensor connected – operating status ready = no leakage present
“Break” relay is energised, i.e. electrical contact between terminals 4 - 5;
“Alarm” relays are de-energised, i.e. electrical contact between terminals 6 - 7, 9 – 10
When the RDW 03 is disconnected from the power supply,
the “Break” relay is de-energised = fail safe for system safety.
If a leak is detected, the “Alarm” relays are energised;
recommendation: use terminals 6 - 7, 9 - 10 = fail safe for detecting a leak.

Commissioning
A suitable overcurrent protection mechanism must
be provided in the power supply of the device and
labelled with the name of the device. This also
serves as a separator, for all poles, and must be
easily reachable for the user.
DANGER!
Disconnect the device from the power supply befo-
re work on the wiring.
NOTICE
i
Loss of function due to incorrect procedure.
• All maintenance and troubleshooting work
may only be carried out by authorised qualified
personnel.
• Directive 2014/35/EU must be taken into
consideration.
The company operating the device must maintain it
in a proper condition, operate it correctly, monitor it
and clean it regularly.
• Use a screwdriver to knock out the required
cable entries in the terminal compartment and
mount the included cable glands and lock nuts
• Connect the sensor to terminals of the
electronic monitoring (see terminal assignment)
• Connect floating contacts
(see terminal assignment)
• Connect supply voltage, either AC 230 V or
DC 24 V (safety extra-low voltage according to
VDE 0100/ T 410)
i NOTE
The application of the supply voltage causes the
automatic insertion of the RDW 03 system (this
guarantees the automatic restart after power failure):
LED ‘ready’ lights up
(dry point sensor or sensor cable)
Leakage check
• immerse the leakage probe in about 3 mm or
the sensor cable in about 5 cm of water:
LED ‘leakage’ lights up
buzzer sounds
• dry point sensor or sensor cable
• confirm with the ‘reset’ button
(step 1: buzzer o)

Open circuit test
• Reconnect the terminal resistance:
‘Break’ LED lights up
• Press ‘RESET’ button twice
(step 1: buzzer o):
System is in monitoring mode
Sensitivity of the sensor
The sensitivity of the system can be changed using
the potentiometer in the terminal compartment.
Instructions for installing the sensor cable
based on the example of a raised floor
The correct time for installation
Other work, including cleaning, should be com-
pleted before installing the sensor cable in order
to prevent the sensor cable from damage caused
by other trades.
Installation
• the floor must be dry, dirt-free and possibly
dust-free
• use self-adherent tape to fix the sensor cable
where required (e. g. false bottom)
• fasten the sensor cable to the floor at
1 m - distances
• the sensor cable must not be flattened against
metal parts as the electronic evaluation system
checks the cable for its electrical resistance.
• condensate dripping from pipes or coolers must
not wet the sensor cable
• for flush-mounting in walls or other
confinements, a non detecting connection
cable, a protective conduit or a flexible tube
must be used
• locations where the sensor cable could be
damaged should be marked by way of labels
(‘Attention - sensitive sensor cable’)
• the sensor cable must rest on the surface to be
monitored (obstacles such us directly installed
cable routes may be jumped if leakage
monitoring can be immediately continued on
the other side of the obstacle)
• after its installation and prior to the system
start-up, the sensor cable must be checked for
its insulation resistance
(measuring circuit: >10 MΩ).
i NOTE
In this case remove the end resistor!
NOTICE
i
BARTEC recommends a system inspection at least
once a year. The countermeasures introduced
when detecting a leak must be adjusted in terms
of weighting and reaction speed to the damage to
be averted. The operator must clarify insurance
requirements (building, liability etc.), for example
inspection intervals, scope of inspections, training
of the operating sta.
WARNING!
Serious accidents due to damaged components.
• Inspect the device and cables regularly for
cracks, damage and to check that connections
are secure.
NOTICE
i
Damage to the device due to incorrect cleaning.
• Do not use compressed air to clean soiled
RDW 03 monitoring electronics.
Troubleshooting
WARNING!
Serious accidents due to the failure to use original
spare parts.
• Only replace parts with original parts.
Faulty devices can be repaired. They must be
replaced in line with these Operating Instructions.
Accessories, spare parts
i NOTE
The monitoring electronics require a terminal
resistance (05-0080-0164) in the last PS point
sensor (factory installed) or at the end of the SCR
sensor cable.
See the BARTEC catalogue for further accessories
and spare parts.
Disposal
The components of the BARTEC water detection
system contain metal and plastic parts.
Statutory requirements for electronic waste must
therefore be complied with during disposal (e.g.
disposal by an approved disposal company).
Maintenance
The point sensor itself is maintenance-free.
• Care must be taken during installation that the
electrodes are clean and free from grease.
This is achieved by cleaning with methylated
spirits or a household detergent with fat
solvent. You must ensure by means of suitable
inspection intervals in line with the degree
of contamination or the amount of dust to be
expected that the electrodes are kept clean
and free from grease.
• Plug-in connections on the installation route
must be installed so that they are protected
against moisture. When monitoring surfaces,
the customer should use spacers on the floor
for this purpose.
