Operating Instructions
Optical point sensor PSO+ and PSO Type: 17-85M6-1102.A00
Operating Instructions Optical point sensor PSO+ and PSO Type 17-85M6-1102.A00
Intended use
The PSO+ point sensor and the PSO point sen­sor are components of the BARTEC water detec­tion system. They can be combined with the SCR sensor cable and/or the PS point sensor. The RLW,
net
, RDW03 and RDA01 electronic monitoring
RLA systems as well as corresponding accessories (see catalogue) are also part of the BARTEC water de­tection system.
Product description
General information
The point sensor is used to detect electrically non-conductive liquids such as oil, enabling the location of the leak to be detected quickly.
Thanks to the special optics, it can operate reliably also when facing metallic surfaces (e.g. oil catch pan made of sheet steel).
The PSO point sensor consists of a PVC sensor enclosure with three spacer feet. In conjunction with the BARTEC electronic monitoring system (e.g. RDW, RDA, RLW or RLA), an alarm is sig­nalled as from a leak height of 2 mm (height can be adjusted using the screw feet).
The removable enclosure lid permits free access to the terminals. Up to 50 sensors can be connected in series. An integrated final resistance makes it possible to monitor cable breaks.
The integrated load relay can operate actuators, such as a check valve, directly on site. A second changeover contact reports the circuit state to the electronic monitoring system
Dierence between PSO+ and PSO
The PSO+ point sensor and PSO can be supplied centrally with DC 24 V via the signal cable. It is similarly possible to provide a decentralised power supply by means of a commercially available plug­in power supply unit.
With its additional terminal block, the PSO+ point sensor can be combined with the SCR and PS sen­sors as required. In addition, this terminal block and the integrated series resistors with R = 62 Ω corresponding to 10 m sensor cable permits the positioning function (with RLA
net
or RLW).
Safety instructions
Before commissioning, please make certain that the PSO+ and the PSO are suitable for the designated use.
• For electrical installations, the pertinent installation and operating regulations must be followed (e.g. DIN VDE 0100 series or other relevant national regulations).
• All general statutory regulations and other binding guidelines on occupational health and safety, accident prevention and environmental protection must be complied with.
Assembly and commissioning
Assembly
The device must be positioned in a suitable place where leaked liquid can collect. This is aided by a catch pan with a ridge.
Installation
The device must be connected according to the cir­cuit diagram, complying with the specified current/ voltage data. The ends of the conductors should be appropriately prepared when connecting stranded or finely stranded conductors.
Plug-in connections on the installation path must be laid so they remain dry. For this purpose, the cus­tomer must insert spacers between the conductor and the ground when monitoring areas.
Commissioning
The device may only be operated in a clean and un­damaged condition. If damage is visible, the device must be taken out of service and corresponding repair measures must be initiated.
Commissioning must be performed in the following steps:
• Connect the device to the power supply
• The green LED indicates that voltage is ON
• The red LED signals that the relay is active (fail-safe circuit), when the optics are in the open
• If the optics are immersed in the leaked liquid, the relay sinks and the red LED is extinguished
Operation, maintenance
The company operating an electrical installation must keep the operating equipment in good con­dition, must operate and monitor it as intended, and must carry out maintenance and repair work.
All electrical equipment must be selected according to its suitability. Applicable laws and guidelines must be followed before putting it back into operation. The specified safety instructions must be observed before maintenance and/or troubleshooting.
It is necessar y to ensure that the optics of the PSO+ and of the PSO are kept clean and free of grease at intervals that are suitable considering the degree of soiling or dust to be expected.
Alarm management
Alarm output
The isolated relay output is primarily used as group alarm output in the closed current/NC = normally closed” operating mode. This means the contact remains closed (relay is activated) as long as there are no faults. This operating principle enables wire breaks and power failures to be detected (1).

Measuring circuit monitoring
The connected point sensor is transmitted to elec­tronic monitoring system (e.g. RDW, RDA, RLW or RLA) via the relay contact NC - C. This also allows the parallel connection of several point sensors (2).
In addition, the measuring circuit is monitored for the following errors:
• Interruption of the measuring circuit If this error occurs, the load circuit is opened and a
corresponding fault message generated.
