  • 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

    CONNECTION Each GFW has an optically isolated serial port RS485 (PORT 1) with standard Modbus protocol via connectors J8 and J9 (type RJ10). You can insert a serial interface (PORT 2). There are various models based on the field bus required: Modbus, Pro- fibus DP, CANopen, DeviceNet and Ethernet.

  • Page 56: Selftuning

    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.

  • Page 57: Softstart

    SOFTSTART If enabled, this function partializes power based on a percentage of time elapsed since instrument switch-on compared to the set time of 0.0 ... 500.0 min (“SoFt” parameter CFG phase). Softstart is an alternative to selftuning and is activated after each instrument switch-on.

  • Page 58: Software Shutdown

    SOFTWARE SHUTDOWN Running the software shutdown procedure causes the following: 1) Reset of Autotuning, Selftuning and Softstart. 2) Digital input enabled only if assigned to SW shutdown function. 3) In case of switch-on after SW shutdown, any ramp for the set (set gradient) starts from the PV. 4) Outputs OFF: except for signals them of reference rL.4 and rL.6 that they come forced ON 5) Reset of HB alarm.

Average power is the average power calculated in the last 300 sec. The alarm reset and reference power update take place only at switch-on or after a setpoint change.
