SENSOR INSTALLATION AND MAINTENANCE
Before connecting the power cable, lift the cover of the plastic connection head using a flat screwdriver. The input cable is connected to the terminals according to the wiring diagram through the loose eyelet. The recommended wire section is 0,35 to 1,5 mm2. The diameter of the circular section cable can range from 4 to 8 mm. To ensure the IP 65 protection value, the grommet must be tight and the cover must be put on after connecting the input cable.
SENSORS WITH CONNECTOR:
The input cable with connector is connected to the RSFM4 connector, which is part of the sensor head. Optionally the stand-alone CONEC 43-00092 connector, or an input cable with a length of 5 m, equipped with a straight type RKT connector or a rectangular type RKWT connector can be delivered. To ensure the protection value IP 65, the connectors and the sensor cover must be tightened and checked. In the event that the input cable is laid near high voltage conductors or those supplying equipment that create an interfering electromagnetic field (for example, inductive cables).
charge the equipment), a shielded cable should be used. The openings for the installation of the plastic clamp must be drilled in accordance with the sketch dimensions on which the opening diameters and the distances from their centers are illustrated. After installation and connection of the sensor to the sequential system assess the electrical equipment that the sensor is ready to use. The sensor does not require any particular maintenance. The device can be used in any working position, but the eyelet must not point upwards. The sensors are mounted using two methods: a) directly on the flat surface using two Ø 4,5 mm screws in the openings in the corners of the head. The dimension 13 mm (distance to the barrier in the head connection) must be added to the length necessary for attachment to a base; b) by means of the lateral support which must be fixed for example to a wall by means of two Ø 4,5 mm screws. To ensure watertightness, it is necessary to carefully tighten the eyelet. During the closing of the head by means of the cover the clips must be broken in the original position.
MODIFICATION AND CUSTOMIZATION FOR THE STANDARD DETECTORS MANUFACTURED, THE FOLLOWING PARAMETERS CAN BE MODIFIED:
- possibility of coating two sensitive elements.
- possibility of encapsulating non-standard temperature sensors (DALLAS, TSic, KTY, SMT, etc.).
- Accuracy class A (with the exception of Ni 10000/5000, Ni 10000/6180, T1 = Ni 2226 sensors, NTC resistance 20 kΩ).
- connection option with three or four wires.
- possibility of providing custom temperature ranges for temperature sensors with converter.
