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 6: Instrument Architecture

    INSTRUMENT ARCHITECTURE The modular power controller’s flexibility permits replacement of previous-version such as GEFLEX (GFX), GFX4 and GFX4-IR 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 at most 3 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/GFW The modes are selected with dip-switch-7. GFX-compatible mode (dip-switch-7 =ON) This lets you uses supervision programs created for Geflex modules. Memory is organized in at most 3 groups: Zone 1 for the variables of the module GFW-M Zone 2 for the variables of the module GFW-E1 Zone 3 for the variables of the module GFW-E2...

  • Page 8: Connection

    Serial communication time constraints in Modbus RTU The following time constraints must be complied with in order to allow correct serial data exchange with the device: Reading Word/Register parameters: Reading N consecutive parameters, with N from 1 to 16, requires a time of almost 50 ms. In this case the following read and write Modbus command, to the same node, must be sent after this interval time.
  • Page 9 Installation of the “MODBUS” serial network A network typically has a Master that “manages” communication by means of “commands” and Slaves that interpret these commands. GFW are considered Slaves to the network master, which is usually a supervision terminal or a PLC. They are positively identified by means of a node address (ID) set on the rotary switches (tens + ones).

    HB ALARM (Heater Break Alarm) This type of alarm identifies load break or interruption by measure the current delivered by means of a current transformer. The following three fault situations may occur: - delivered current is lower than nominal current: this is the most common situation, and indicates that a load element is breaking. - delivered current is higher than nominal current: this situation occurs, for example, due to partial short circuits of load elements.

In case of HSC firng mode, the Heater Break alarm teach-in function doesn’t calibrate at 5%, 3%, 2% and 1% in order to avoid high peak currents due to the low impedence at very low temperature of the IR lamp filament.
