SENSORS
Fundamental components for process control, Gefran's sensors measure main variables such as temperature, pressure, position and force. The main element of the sensors is produced in cleanrooms, in environments protected from any kind of pollutant and equipped with highly technological work and control instruments. 

COMPONENTS
Three product lines are dedicated to indicating and controlling process variables: static groups, regulators and electronic indicators. A range of constantly evolving devices capable of providing innovative solutions and responding to the needs of process optimisation and intelligent management of energy consumption. These devices complete the range of support services offered and faster delivery times, the key factors that make Gefran a competitive and reliable partner.

AUTOMATION PLATFORMS
Gefran designs and manufactures automation control systems offering machine constructors a wide range of specific components (Unit Control Panels, Operator Interfaces, input/output systems, as well as programmable logic controllers and industrial PLC). This dedicated division also designs and develops solutions that adapt to customer projects, offering unique and exclusive "turnkey" solutions.

MOTION CONTROL
This range of products, designed and manufactured at the Drive and Motion Control Unit of Gefran in Gefrenzano (VA), consists of continuous and alternating current electronic drives and electric motors, including a complete range to fully satisfy the needs of industrial automation. The line also includes a series of inverters for the domestic and industrial photovoltaic industry.

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.

Second input can be configured as remote setpoint of single loop.

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.

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 128 steps (each step consisting of a ramp and a hold), groupable in a maximum of 16 programs, are available for applications with setpoint profiles.

Enable inputs, event outputs, and messages to display can be assigned to each step.

Double programmer with synchronous and asynchronous base times for activating two setpoint profiles (even separate) assigned to the two loops.

On-board configuration and graphic configuration with GF_eXpress.

Valve positioner

Models to control motorized valves, with or without feedback.

The position is calculated for floating valves.

For valves with potentiometer via auxiliary input you can control and display the position.

Connectivity

Modbus RTU on RS485 2 wire connection.

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.
