1 • PRELIMINARY INSTRUCTIONS

This section contains information and warnings of a general nature which should be read before procee-

ding with controller installation, configuration and use.

General description

GF_Looper is an advanced series of multichannel con-

trollers, offered in configurations of up to 16 channels and

structured for simple use and complete functionality for

managing a wide range of applications.

GRAPHIC INTERFACE

The operator interface, based on LCD TFT color touch

screen (3.5” and 5.7”) offers maximum simplicity of use.

A series of graphic pages structured with different details

provide complete monitoring of GF_Looper operation.

Icons facilitate access to the graphic pages, making navi-

gation immediate and reliable.

Group pages offer an overview of enabled zones, with

display of principal data such as PV, SP, output power,

state of main alarms.

To simplify a few repetitive operations, the group page

offers a control to activate/deactivate control actions for

all configured zones, a control (Up/Down) for synchroni-

zed change of all work Set Points in control zones, and

selection between SP and SP2 for immediate production

change.

Detail pages of single control zones provide a complete

view of the state of all standard control parameters, such

as PID and alarm thresholds.

Any fault conditions, such as broken or short-circuited

sensor, or partial or total load interrupt, are displayed

both as alarms and graphically with dedicated icons.

ALARM AND RECIPE MANAGEMENT

Integrated alarms management combined with an alarm

notice on all pages provides an immediate check of work

conditions of the controlled process.

An acknowledgement and deletion command is provided

for all alarms.

For recipes, the work parameters of all configured zones

can be saved to file.

This management simplifies machine setup operations in

case of production changes and guarantees error-proof

operation.

USER LEVEL AND MULTI-LANGUAGE MANAGEMENT

So that the GF_Looper may be used by operators of

different nationalities, multi-language management provi-

des simple and intuitive video messages translated into

the selected language.

Pre-set password levels guarantee controlled access to

the various functions according to the authorization assi-

gned to each operator.

DATA STORAGE

Trend pages with variable selection and sampling time

configuration (min/sec) offer paperless recording fun-

ctions.

Storage of sampled Trend data on file also provides inte-

grated DataLogging functions.

DataLogging values can be exported to .CSV file and

transferred to PC on a USB drive. Start/Stop recording

commands let you optimize the number of stored data

for better analysis.

REMOTE ACCESS

An Ethernet connection with Modbus TCP protocol provi-

des an efficient tool to link GF_Looper to HMI acquisition

or supervision systems.

A complete map of variables with all general information

on GF_Looper operation and configuration is provided for

data exchange with a Modbus TCP master.

For remote diagnostics or machine setup functions,

there is a simple solution based on the graphic part of

GF_Looper that uses a Windows PC with Ethernet con-

nection to the field instrument.

CONTROLLER

Advanced control algorithms provide excellent manage-

ment of process variables.

Various types of control are possible: ON/OFF, P, PI,

PID, both heat or cool only and heat+cool.

In addition, cooling can be set by specifying the fluid

used: air, oil, water.

Calculation of the best process parameters is extremely

rapid and efficient thanks to the use of sophisticated

automatic tuning processes.

The use of advanced tuning lets you check the best PID

parameters under all conditions.

ALARMS

Two alarm thresholds (minimum and maximum) for

each zone.

For each alarm, you can select:

- the control variable to be assigned

- the threshold value

- the hysteresis value

- 5 properties (with latch, disable at power-on, deviation/

symmetrical, absolute/relative, direct/inverse).

LBA, HB, SBR alarms can be set; the presence of the

alarm is displayed on the screen via LEDs.

2 • INSTALLATION AND CONNECTION

This section contains the instructions necessary

for correct installation of the GF_LOOPER into

the machine control panel or the host system

and for correct connection of the controller

power supply, inputs, outputs and interfaces.

Before proceeding with installation read the

following warnings carefully!

Remember that lack of observation of these

warnings could lead to problems of electrical safety

and electromagnetic compatibility, as well as invali-

dating the warranty.

Electrical power supply

• theGF_LOOPERisNOTequippedwithanOn/Off

switch: the user must provide a two-phase

disconnecting switch that conforms to the required

safety standards (CE marking), to cut off the power

supply upstream of the controller.

The switch must be located in the immediate vicinity

of the controller and must be within easy reach of the

operator.

One switch may control more than one instrument

• ifthecontrollerisconnectedtoNOTisolatedelectrical

equipment (e.g. thermocouples), the earth connection

must be made with a specific conductor to prevent

the connection itself from coming directly through the

machine structure.

• iftheGF_LOOPERisusedinapplicationswithriskof

damage to persons, machinery or materials, it is

essential to connect it up to auxiliary alarm

equipment. It is advisable to make sure that alarm

signals are also triggered during normal operation.

The controller must NOT be installed in flammable or

explosive environments; it may be connected to

equipment operating in such atmospheres only by

means of appropriate and adequate types of

interface, conforming to the applicable safety

standards.

Notes Concerning Electrical Safety and

Electromagnetic Compatibility:

CE MARKING: EMC Conformity (electromagnetic

compatibility)

in accordance with EEC Directive 2004/108/CE.

GF_LOOPER series are mainly designed to operate in

industrial environments, installed on the switch boards

or control panels of productive process machines or

plants. As regards electromagnetic compatibility, the

strictest generic standards have been adopted, as indi-

cated in the table below.

The internal power supply 24Vdc is galvanically isolated and protected against polarity reversal and short circuits.

The panel has a power terminal.

The connector diagram is shown in Figure 11

Note:

check that the power supply is able to deliver the power needed for correct operation of the device.

The device must always be grounded. Grounding helps limit the effects of electromagnetic noise on the control

system. All electronic devices of the control system must be grounded. Ground the devices in a manner confor-

ming to applicable standards and regulations.

3.4.2 RS-485 port

The terminal uses the RS-485 port to dialog according to OSI specifications at the physical level defined by stan-

dard EIA-485.

The RS-485 port is optically isolated and allows dialog from 9.6 kBaud to 115 kBaud via an RJ10 4p4c connector

(Registered Jack type 10 with 4 positions and 4 contacts). Signal assignment is shown in Table 5.

Length and type of connection cable between GF_PROMER and GFX / GFX4 / GFX4-IR / GFXTERMO4 units:

- standard telephone up to 10m

- shielded cable up to 150m (shield to GND)

- woven and shielded cable (Belden, shield to GND) for distances > 150m up to a maximum of 1200m

6 • MAINTENANCE

This section gives the information and the necessary

warnings for routine maintenance of the controllers

and contains a Troubleshooting Guide which should

be read before seeking help from the Gefran

Customer Service Assistance, in the event of instru-

ment malfunction.

If installed and configured correctly according to the instruc-

tions and the recommendations provided in Sections 2 and 4

of these Instructions for use, the Controller will work normally

without any need for maintenance, apart from the usual ope-

rations of cleaning the faceplate, and if necessary the internal

parts of the instrument.

Cleaning the Controller

To clean the faceplate and the case use only a cloth

dampened in water or ethyl alcohol.

Do not use hydrocarbon-based solvents

(trichiorethylene, petrol, etc.).

Do not use compressed air to remove dust from the

electronic circuit boards, if necessary use a clean

brush with soft bristles.

Repairs

Repairs to the Controller must only be carried out by

qualified technicians, properly trained and authorized

by Gefran.

Any attempts at repair or modification of the Controller

hardware characteristics by unauthorized personnel

will invalidate the warranty.
