  • 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

    - GFX compatible mode: as if there were 4 separate instruments (recommended for retrofitting projects and/or replacement of damaged instruments); - GFX4 mode: as a single instrument with the same functions as 4 separate instruments, but with possibility of inter- action among the various parameters, inputs and outputs (recommended for new projects).

Therefore, you can use the best sampling time for the application being run and, especially, for load type, since activation of the scan to identify faults on the load with fast systems and short cycle times may be critical for stable temperature control.

These alarms are set as follows: - select the reference variable to be used to monitor the value (parameters A1.r, A2.r, A3.r and A4.r): the origin of the variable can be chosen from the process variable PV (generally linked to the main input), the ammeter input, the voltmeter input, the auxiliary analog input, or the active setpoint.

  • Page 29: Lba Alarm (Loop Break Alarm)

    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 30: 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 trans- former. 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 35: 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. Is provided the intervention of the alarm also for speed of temperature rise (derivate) INPTC greater than 7°C in 12 seconds.

    SELFTUNING This function is valid for single-action (either heat or cool) systems and for double-action (heat/cool) systems. Selftuning is activated to calculate the best control parameters when starting the process. The variable (example: temperature) must be the one assumed at zero power (room temperature). The controller supplies the maximum power set until reaching an intermediate point between starting value and the setpoint, then resets power.
