  • Page 4: Introduction

    Since it is impossible to foresee all of the installations and environments with which the instrument may be applied, adequate technical preparation and complete knowledge of the instrument’s potentials are necessary. GEFRAN declines all liability if rules for correct installation, configuration, and/or programming are disregarded, as well as all liability for systems upline and/or downline of the instrument.

  • Page 5: Structure Of This Manual

    This manual was originally written in ITALIAN. Therefore, in case of inconsistencies or doubts, request the original manual or explanations from GEFRAN. The instructions in this manual do not replace the safety instructions and the technical data for installation, configuration and programming applied directly to the product or the rules of common sense and safety regulations in effect in the country of installation.

  • Page 6: Communications

    Each GTF has an optically isolated serial port TTL with standard Modbus for GTF 25-120A protocol via connector J2 type RJ10 (J5 for GTF 150-250A). As an option, you may have an optically isolated RS485 serial port with standard Modbus protocol for GTF 25-120° via con- nectors j3 and j4 type RJ10 (J6, J7 for GTF 150-250A).

  • Page 7: Inputs

    The default values (Lo.S = 0.0 and HI.S = 100.0) can be changed to obtain the required scale of the PV in engineering value corresponding to the minimum and maximum of the physical input (V/mA). In automatic mode, the engineering value (PV) is attributed to power Ou.P for values between 0.0 and 100.0. 80961F_MSW_GTF/GTF-Xtra_07-2018_ENG...
  • Page 8 = 1 Lo.S = 0.0 HI.S = 111.1 Since the 0…10V input range is reduced 90% below, the scale interval (HI.S – Lo.S) must be extended upward so that the useful interval (100.0 – 0.0) is 90% (100.0/111.1 = 0.9). 80961F_MSW_GTF/GTF-Xtra_07-2018_ENG...

    ( NOTE: the No_Current alarm trips when the current value on the load is less than 4% of I_nominal of the product. For example, for GTF-25A the alarm trips with load current below 1A). For alarm HB (load partially interrupted), refer to the specific section of this manual.

    Hb.P, determines the HB alarm setpoint. Before activating the function, it is necessary that the GTF is switched on with power, it is recommended, above 50%. In the case of HSC mode or PA for infrared lamps (see parameter Hd.5 option +128), the function activates automatic reading of the power/current curve useful for determining the HB alarm setpoint.
