Operating Instructions
RDA01 Monitoring Electronics
Type 17-85F4-2.22
M
The RDA01 evaluation unit is a component of the
BARTEC water detection system. It operates in
conjunction with the SCR sensor cable and/or the
PS point sensor. Other components of the BARTEC
water detection system are the RLW and RDW03
evaluation units, as well as accessories (see cat-
alogue).
Description
The system quickly and reliably detects small
leakages of liquid, producing a visual and acoustic
alarm signal. At the same time, floating contacts
are set for messages to the building management
system (BMS) and for control tasks.
Safety instructions
The device may only be used within the specified
ambient and operating temperature range. Use in
areas other than those specified or the alteration of
the product by somebody other than the manufac-
turer is not permitted and releases BARTEC from
liability for defects and other liability. Malfunctions
may result from incorrect installation. The gen-
erally applicable statutory regulations and other
binding guidelines relating to occupational health
and safety, accident prevention and environmen-
tal protection must be complied with. Applicable
laws and guidelines must be complied with before
commissioning or putting back into operation. The
equipment may only be used in a clean, undam-
aged state. Modifications and changes are not
permitted.

Mounting, installation and commissioning
WARNING
!
Risk of injury due to incorrect procedure.
All work concerning mounting, dismantling,
installation and commissioning may only be
conducted by authorised qualified personnel.
Pay attention to the type of installation
(for installation /with connection enclosure).
Use suitable tools.
Mounting/dismantling
The monitoring electronics are snapped onto a TS
35 top-hat rail inside the control cabinet.
Installation
Take the following into consideration when con-
necting conductors:
• Remove approx. 6 mm (0.236 in) of the
conductor insulation on the cores.
• Prepare the conductor ends of stranded and
finely stranded conductors: use a suitable
crimping tool to fasten wire end ferrules.
Connection cross-sections: 0.5-2.5 mm²
(21-14 AWG)
• Release terminals.
• Insert conductor.
• Tighten terminals to a maximum torque
of 0.7 Nm.
Terminal assignment: see the following page
NOTICE
i
• Care must be taken when mounting the PS
point sensor that the electrodes are clean and
free from grease. This is achieved by cleaning
with methylated spirits or a household
detergent with fat solvent.
• The mounting and installation instructions for
the SCR sensor cable must be observed.

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.
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.
Check the following before commissioning:
• Device has been correctly installed.
• Device is undamaged.
• Connection has been carried out correctly
(check that the cores are secure).
Care must be taken when mounting the PS point
sensor that the electrodes are clean and free from
grease. This is achieved by cleaning with methylated
spirits or a household detergent with fat solvent.
i
NOTE
Water leakages are detected quickly in accordance
with the volume and the conductivity of the leaked
liquid. The SCR sensor cable has the shortest re-
action time with at least a complete point by point
cover (approx. 5 mm). For reasons of its geometry,
the PS point sensor requires the leaked liquid to
have a minimum height (see the PS point sensor
data sheet for details).
Design measures must be introduced to keep
conductive substances that are not to be detected
away from the sensor (e.g. rainwater, splashing
water, condensate etc.).
NOTICE
i
The presentation of a correctly prepared and com-
pleted acceptance report is essential for warranty
claims. This must include date and signature.
Leakage test
• Immerse the PS point sensor approx. 5mm or
the SCR sensor cable approx. 10 cm in the
expected leaked liquid (or water).
• The ‘Alarm’ LED lights up after approx. 10 secs
• Buzzer is active and floating contact switches
• Dry the PS point sensor or SCR sensor cable
• Press ‘RESET’ button
• ‘Operation’ LED lights up
System is in monitoring mode
Open circuit test
• Briefly remove the terminal resistance on the
last PS point sensor or at the end of the SCR
sensor cable and then reconnect it
• ‘Break’ LED lights up
• Buzzer is active and floating contact switches
• Press ‘RESET’ button
• Operation’ LED lights up
System is in monitoring mode
