  • Page 4: Introduction

    Since it is impossible to foresee all of the installations and environments in 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: Instrument Architecture

    INSTRUMENT ARCHITECTURE The modular power controller’s flexibility permits replacement of previous-version instruments without changing the control software in use. Based on the chosen work mode (see MODBUS SERIAL COMMUNICATION), you can use the instrument in 2 different modes: - GFX compatible mode: as if there were 4 separate instruments (recommended for retrofitting projects and/or replacement of damaged instruments);...

  • Page 7: Serial Communication (Modbus)

    SERIAL COMMUNICATION (MODBUS) There are two Modbus addressing modes for variables and configuration parameters: - GFX compatible - GFX4 The modes are selected with dip-switch-7. All the parameters of formulation are saved in internal storage EEPROM (not flown them), of which a maximum of 100.000 cycles of cancellation is guaranteed/ writing.

  • Page 8: Connection

    There is a single value (Cod) set on the rotary switches; i.e., one for each GFX4-IR instrument. To access the data in each zone, simply add an offset to the address (+1024 for Zone 1, +2048 for Zone 2, +4096 for Zone 3, +8192 for Zone 4).
  • Page 9 - parity Serial 2 = none You can install a maximum of 99 GFX4-IR modules in a serial network, with node address selectable from “01” to “99” in stan- dard mode, or create a mixed GFX4-IR/ GFX4 / Geflex network in Geflex compatible mode in which each GFX4-IR or GFX4 identifies 4 zones with sequential node address starting from the code set on the rotary switches.

    LBA ALARM (Loop Break Alarm) This alarm identifies incorrect functioning of the control loop due to a possible load break or to a short circuited or reversed probe. With the alarm enabled (parameter AL.n), the instrument checks that in condition of maximum power delivered for a settable time (Lb.t) greater than zero, the value of the process variable increases in heating or decreases in cooling: if this does not happen, the LBA alarm trips.

  • Page 32: Hb Alarm (Heater Break Alarm)

    HB ALARM (Heater Break Alarm) This type of alarm identifies load break or interruption by reading the current delivered by means of a current tran- sformer. The following three fault situations may occur: - delivered current is lower than theoretical current: this is the most common situation, and indicates that a load ele- ment is breaking.

  • Page 38: Overheat Alarm

    Overheat alarm The controller has a temperature sensor for the internal heatsink. The temperature value of the heatsink is in variable INPTC; the over_heat alarm trips when the temperature exceeds 85°C. This condition may be caused by obstructed air vents or by a blocked cooling fan. The over-heat alarm is cancelled when the heat sink temperature falls below the value of 75°C.
