Overview

Operator interface

Large LCD display with customization of plastic front panel color and logo.

Graphic display of power, output current or valve position.

Scrolling alphameric display of 25 messages (32 letters each), completely configurable and savable, in three languages.

Thanks to language selection and clear scrolling messages for diagnostics, alarms, and process state, the controller speaks the  user’s language.

Control

Double loop, two configurable universal inputs for thermocouples, resistance thermometers, linear inputs. Aerospace and Automotive applications AMS2750/CQI-9 conformant.

Easy configuration

Guided configuration for manual-free programming, with a few essential parameters and on-line help messages.

Ability to clone configuration among controllers, even with power off and in the field, thanks to a mini portable configurator with Zapper battery.

Extended configuration, creation of work recipes, and firmware updates via PC and GF_eXpress software, even without powering the controllers.

Thanks to the smart configurator function, you obtain the required parameter recipe by answering a few simple questions.

Local configuration and operation with only four keys assigned to LEDs that serve as feedback for the pressed key and as guide to specify appropriate steps.

The initial parameters can always be reset, both from the keypad and from the GF_eXpress Software tool.

Diagnostics, preventive maintenance and energy monitor

Complete diagnostics for broken or incorrectly connected probe, total or partial load break, out of range variables, and control loop faults.

Thanks to the switching count and to the settable alarm thresholds, you can program preventive maintenance to replace worn actuators.

An internal energy counter with alarm for abnormal variations totalizes energy consumptions and costs for constant control.

Function block applications 32 AND, OR, Timer Function Blocks let you create customizable logic sequences for complete and flexible machine control.

The controller’s hardware resources are exploited completely, without any need for external devices such as timers and small PLCs.

There are 8 math function blocks to process analog variables and add/subtract/multiply/ divide, calculate average, root, logarithms and control functions in cascade, and ratio check.

Options are available with 8 digital inputs/outputs and 8 additional relay outputs to be managed via function blocks with state signals via dedicated LEDs on the LCD display.
