  • Page 5: Application

    The transducer is fully configurable through the PD14 programmer. By means of this programmer, one can change the input type, the measu- rement averaging time and rescale the analog output acc. to the indivi- dual output characteristic, and also read out the measured value. 2. TRANSDUCER SET The set of the P20 transducer is composed of: - P20 transducer 1 pc. - User’s manual 1 pc. - Guarantee card 1 pc - Plug with screw terminals 2 pcs.

  • Page 6: Operational Safety

    3. OPERATIONAL SAFETY In the safety service scope, the transducer meets to requirements of the EN 61010-1 standard. Observations concerning the operational safety All operations concerning transport, installation, and commissioning as well as maintenance, must be carried out by qualified, skilled personnel, and national regulations for the prevention of accidents must be observed. Before switching transducer on, one must check the correctness of connections to the network. When connecting the supply, one must remember that a switch or a circuit-breaker should be installed in the building. This switch should be located near the device, easy accessible by the operator, and suitably marked as an element switching the transducer off. Do not connect the transducer to the network through an autotransformer. Before removing the transducer housing, one must switch the supply off and disconnect measuring circuits. The removal of the transducer housing during the guarantee contract period may cause its cancellation. The programmer socket is only use to connect the PD14 programmer. After the transducer programming, one must insert the hole plug. Non-authorized removal of the housing, inappropriate use, incorrect installation or operation, creates the risk of injury to personnel or a transducer damage. For more detailed information, please study the User’s Manual.

  • Page 7: Installation

    4. INSTALLATION 4.1. Fitting way P20 transducers are designed to be mounted on a 35 mm rail accor- ding to EN 60715. The transducer housing is made of a self-extinguishing plastic. Housing dimensions are: 22.5 x 120 x 100 mm. On the transducer outside, there are screw or self-locking terminal strips, which make possible the connection of external wires with a 2.5 mm cross-section (supply and output) and up to 1.5 mm (input). Connector of the PD14 programmer Fig. . Overall dimensions and fitting way of the transducer...

    The electrical connection diagram is also situated on the transducer housing. In case of the transducer work in an environment with high interferences, one must apply shielded wires in the transducer input.

After the connection configuration, one must choose Device -> Trans- ducers P -> P20 from the menu, and next click the Readout icon in order to read out all parameters. One can also read out parameters individually in each group clicking the Refresh push-button.

Configuration of the transducer input type Three developable lists are accessible in the parameter group “Input configuration”, by means of which, one can choose the input type, the measuring range and the measurement averaging time. One must con- firm changes, clicking the Apply push-button. Fig. . View of the LPCon program window “Input configuration”...

  • Page 11: Configuration Of The Individual Analog Output Characteristic

    5.2. Configuration of the analog output characteristic The P20 transducer enables the conversion of measured values into an output signal on the base of the individual linear characteristic of the analog output. On the base of given by the user coordinates of two points, the transducer determines (from the system of equations) coefficients a and b of the individual characteristic.

    Fig. . View of the LPCon program window “Individual characteristic” 5.3. Configuration of the analog output at overflows The user has the additional possibility in the P20 transducer to confi- gure the preservation of the analog output after the signal overflow oc- currence on the measuring input. By default, the service of overflows is switched out – then, after the signal overflow on the input, the output is still proportional to the steered up input beyond the basic output range. After switching the overflow service on, the user can define himself by which value the output is to be steered up after the occurrence of the higher or lower overflow.

Readout of the measured value By means of the LPCon program, one can also read out the actually measured value, check the output type, read out the factory serial num- ber and the programming version. These quantities are located in the Measured values window.
