Overview

Operator interface

Large LCD display with customization of colors assigned to PV and SV display, of color of plastic faceplate, and of logo.

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.

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

Sixteen 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

Tuning

Advanced tuning algorithms ensure stable and accurate control even with critical or very rapid thermal systems, engaging automatically when necessary.

Timer

Three types of timers let you set delay times before activating the control, hold times on the setpoint value, and timed changes of programmed setpoints.

Setpoint Programmer

Models with twelve ramp and hold steps, groupable in four programs, with enable inputs and event outputs, are available for applications with setpoint profiles.

On-board configuration and graphic configuration with GF_eXpress.

Valve Positioner

Models to control motorized valves, without feedback.

Valve position is calculated and shown on the display.

General characteristics

The controller is completely software configurable without accessing the internal electronics.

The universal main input accepts thermocouple sensors, resistance thermometers, and linears.

The controller can be replaced at any time simply by removing the faceplate, without any additional procedures
