INTRODUCTION
The modular power controller described in this manual and shown on the cover is a separate unit for the independent
control of a maximum of 3 zones. It offers high applicative exibility thanks to the extended congurability and programmability
of its parameters.
Instrument conguration and programming must be performed with a GFW-OP or a PC connected in USB/RS232/
RS485, with specic GF_eXpress application software.
Since it is impossible to foresee all of the installations and environments in which the instrument may be applied,
adequate technical preparation and complete knowledge of the instrument’s potentials are necessary.
GEFRAN declines all liability if rules for correct
installation, conguration, and/or programming are
disregarded, as well as all liability for systems upline
and/or downline of the instrument.
FIELD OF USE
The modular power controller is the ideal solution for applications in heat treatment furnaces, in thermoformers, in
packaging and packing machines and, in general, in standard temperature control applications. Nevertheless, because it is
highly programmable, the controller can also be used for other applications provided they are compatible with the instrument’s
technical data.
Although the instrument’s exibility allows it to be used in a variety of applications, the eld of use must always conform to the
limits specied in the technical data supplied.
GEFRAN declines all liability for damage of any
type deriving from installations, congurations, or
programmings that are inappropriate, imprudent, or
not conforming to the technical data supplied.
Prohibited use
It is absolutely prohibited:
- to utilize the instrument or parts of it (including software) for any use not conforming to that specied in the technical docu-
mentation supplied;
- to modify working parameters inaccessible to the operator, decrypt or transfer all or part of the software;
- to utilize the instrument in explosive atmospheres;
- to repair or convert the instrument using non-original replacement parts;
- to utilize the instrument or parts of it without having read and correctly understood the technical documentation supplied;
- to scrap or dispose of the instrument in normal dumps; components that are potentially harmful to the environment must be
disposed of in conformity to the regulations of the country of installation.

STRUCTURE OF THIS MANUAL
This manual was originally written in ITALIAN. Therefore, in case of inconsistencies or doubts, request the original
manual or explanations from GEFRAN.
The instructions in this manual do not replace the safety instructions and the technical data for installation, conguration and
programming applied directly to the product or the rules of common sense and safety regulations in effect in the country of
installation.
For easier understanding of the controller’s basic functions and its full potentials, the conguration and programming parameters
are grouped according to function and are described in separate chapters.
Each chapter has from 1 to 3 sections:
- the rst section presents a general description of the parameters described in detail in the following zones;
- the second section presents the parameters needed for the controller’s basic applications, which users and/or
installers can access clearly and easily, immediately nding the parameters necessary for quick use of the controller;
- the third section (ADVANCED SETTINGS ) presents parameters for advanced use of the controller:
this section is addressed to users and/or installers who want to use the controller in special applications or in applications
requiring the high performance offered by the instrument.
Some sections may contain a functional diagram showing interaction among the parameters described;
- terms used on other pages of the manual (related or supplemental topics) are shown in underlined italics and listed
in the index (linked to IT support).
In each section, the programming parameters are shown as follows:
400*
21 - 29 - 143 tYP. R/W Type of probe, signal, enable, custom
linearization and main scale input

INSTRUMENT ARCHITECTURE
The modular power controller’s exibility 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 retrotting projects and/
or replacement of damaged instruments);
- GFX4/GFW mode: as a single instrument with the same functions as at most 3 separate instruments, but with
possibility of interaction among the various parameters, inputs and outputs (recommended for new projects).
New shared parameters, are accessible for both modes and permit more advanced functions such as:
604 FLt.2 R/W Digital filter for auxiliary input 0.0 ... 20.0 sec 0.1
In addition to having a CUSTOM group of parameters for dynamic addressing, GFX4/GFW mode lets you use a single
communication network node instead of 3 nodes as in GFX compatible mode.
When programming, keep in mind that some of the
addresses (parameters) described in this manual
exist at most 3 times, specied by address node
(ID).

SERIAL COMMUNICATION (MODBUS)
There are two Modbus addressing modes for variables and conguration 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 Geex 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
In each zone, the variables and parameters have the same address as a Geex instrument; the value (Cod) set on
the rotary switches corresponds to that of Zone 1; the values in the other zones, if expansions are present, are sequential.
Examples:
if the rotary switches have value 14, node 14 addresses Zone 1 (GFW-M), node 15 Zone 2 (GFW-E1), node 16 Zone 3 (GFW-E2).
The power Ou.P for Zone 1 has address Cod 2, the Ou.P for Zone 2 has address Cod+1, 2, etc...
Parameter out.5, which denes the function of output OUT 5 on the GFW, has address Cod 611.
GFX4/GFW mode (dip-switch-7=OFF)
This lets you optimize the efciency of serial communication by integrating at most 3 zones in the GFW. Memory is
organized in 4 groups: 3 already in GFX-compatible mode, plus one group dened as custom:
- Custom (additional memory map for dynamic addresses)
- 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
The custom group contains variables and parameters for a maximum of 120 words. The meaning of these words can
be changed.
There is a single value (Cod) set on the rotary switches; i.e., one for each GFX4/GFW instrument. To access the data
in each zone, simply add an offset to the address (+1024 for Zone 1, +2048 for Zone 2, +4096 for Zone 3).
Words in the custom group have addresses 0,...,119. The variables and parameters are dened by default. At ad-
dresses 200,...,319 we have words containing the value of the address of the corresponding variables or parameters. These
addresses can be changed by the user, offering the ability to read/write data with multi-word messages structured according
to various supervision requirements.
Protection of Maps 1-2
You have to write the value 99 on addresses 600
and 601 to enable change of the custom group
(addresses 200... 319).
This value is reset at each switch-on.
Examples:
you can access the Ou.P variable in Zone 1 with address Cod, 1+1024 or address Cod, 11 custom variable 12 (address Cod,
211 has value 2+1024);
you can access the Ou.P variable in Zone 2 with address Cod, 2+ 2048 or address Cod, 40 custom variable 41 (address Cod,
240 has value 2+2048);
if you want to read the 3 powers in sequence at the rst 3 addresses, set Cod, 200 = 1026, Cod.201 = 2050, Cod,202 = 4098.

880963B_MSW_GFW_11-2012_ENG
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 eld bus required: Modbus, Pro-
bus DP, CANopen, DeviceNet and Ethernet.
This communication port (PORT 2) has the same Cod address as PORT 1.
The parameters for PORT 2 are bAu.2 (select baud-rate) and Par.2 (select parity).
The Cod parameter (read only) shows the value of the node address, settable from 00 to 99 with the 2 rotary switches; the
hexadecimal settings are reserved.
A parameter can be read or written from both communication ports (PORT 1 and PORT 2).
Changing the bAu (select baud-rate) and/or PAr (select
parity) parameters may cause communication failure.
To set the bAu and PAr parameters, you have to run the Autobaud procedure described in the “Instruction and warnings” manual.
Installation of the “MODBUS” serial network
A network typically has a Master that “manages” communication by means of “commands” and Slaves that interpret
these commands.
GFW are considered Slaves to the network master, which is usually a supervision terminal or a PLC.
They are positively identied by means of a node address (ID) set on the rotary switches (tens + ones).
GFW have a ModBus serial (Serial 1) and optional Fieldbus (Serial 2) serial (see order code) with one of the following
protocols: ModBus, Probus, CANopen, DeviceNet, Ethernet, EtherCAT and EthernetIP.
The following procedures are indispensable for the Modbus protocol.
For the remaining protocols, see the specific Geflex Profibus, Geflex CANopen, Geflex DeviceNet, Geflex Ethernet,
GFX4-EtherCAT and GFX4-ETH1 manuals.
GFW modules have the following default settings:
- node address = 0 (0 + 0)
- speed Serial 1 = 19200 bit/s
- parity Serial 1 = none
- speed Serial 2 = 19200 bit/s
- parity Serial 2 = none
You can install a maximum of 99 GFW modules in a serial network, with node address selectable from “01” to “99” in standard
mode, or create a mixed GFW / GFX4 network in GFX compatible mode in which each GFW identies 3 zones with sequential
node address starting from the code set on the rotary switches.
In short, the valid rotary switch settings (tens + ones) are:
- (0 +0) = Autobaud Serial 1
- (B +0) = Autobaud Serial 2

MAIN INPUT PID
The modular power controller has one main input (IN1) to control, to which you can connect temperature sensors
(thermocouples and RTD), linear sensors or custom sensors to acquire process variable (PV) values.
These type of input is optional.
To congure, you always have to dene the type of probe or sensor (tYP), the maximum and minimum scale limit
(Hi.S – Lo.S) for the process variable value, and the position of the decimal point (dP.S).
If the sensor is a thermocouple or resistance thermometer, the minimum and maximum limits can be dened on the specic
scale of the sensor. These limits dene the width of the proportional control band and the range of values settable for the
setpoint and alarm setpoints.
There is a parameter to correct the offset of the input signal (oF.S): the set value is algebraically added to the read
of the process variable.
You can read the state of the main input (Err) in which an input error is reported: when the process variable goes
beyond the upper or lower scale limit, it assumes the value of the limit and the corresponding state reports the error condition:
Lo = process variable < minimum scale limit
Hi = process variable > maximum scale limit
Err = Pt100 in short circuit and input value below minimum limit,
4...20mA transmitter interrupted or not powered
Sbr = Tc probe interrupted or input value above maximum limit
If noise on the main input causes instability of the acquired value, you can reduce its effect by setting a low pass
digital lter (Flt). The default setting of 0.1sec is usually sufcient.
You can also use a digital lter (Fld) to increase the apparent stability of the process variable PV; the lter introduces
a hysteresis on its value: if the input variation remains within the set value, the DPV value is considered unchanged.

ADVANCED SETTINGS
Linearization of input signal
The modular power controller lets you set a custom linearization of the signal acquired by the main input for signals coming
from sensors and for signals coming from custom thermocouples.
Linearization is performed with 33 values (S00 ... S32: 32 segments).
S33, S34, S35 are an additional 3 values to be inserted in case of linearization with custom CT.
- Signals from sensors
For signals coming from sensors, linearization is done by dividing the input scale into 32 zones of equal dV amplitude, whe-
re:
dV = (full-scale value – start of scale value) / 32
Point 0 (origin) corresponds to the engineering value attributed to the minimum value of the input signal.
Subsequent points correspond to the engineering values attributed to input values equal to:
Input value (k) = Minimum input value + k * dV
where k is the order number of the linearization point
For custom linearization (tYP = 28 or 29):
- LO is signaled with input values below Lo.S or at minimum
calibration value.
- HI is signaled with input values above Lo.S or at maximum
calibration value.

value set in S.32 with limit Hi.S.
The engineering values calculated in this way by the user can be set by means of the following parameters.

CURRENT VALUE IN LOAD
The RMS current value is read in variable Ld.A of each zone.
If zone 1 has a 3-phase load, variable Ld.At contains the average value of the three RMS currents. The Ld.A of the rst three
zones contain the RMS current value on lines L1, L2 and L3, respectively..
Accuracy is better than 1% in start modes ZC, BF and HSC.
Accuracy is better than 3% in PA mode with conduction angle >90°, and better than 10% for lower conduction angles.
The circulating current in the load is acquired with a 0.25ms sampling time.
In addition, there are the following parameters for a zone with single-phase load:
I.tA1 instantaneous ammeter value
I.AF1 ltered ammeter value (see Ft.tA)
I1on current with active control
o.tA1 ammeter input offset correction
Ft.tA ammeter input digital lter
There are also the following parameters if zone 1 has a three-phase load:
I.tA1, I.tA2 and I.tA3 instantaneous ammeter value on line L1, L2 and L3
I.AF1, I.AF2 and I.AF3 ltered ammeter value (see Ft.tA) on line L1, L2 and L3
I1on, I2on and I3on current with active control
o.tA1, o.tA2 and o.tA3 ammeter input offset correction on line L1, L2 and L3
Ft.tA ammeter input digital lter
If diagnostics detects a fault condition on the load, the red ER LED will ash in synch with yellow LED O1 or O2 or O3 for the
zone in question.
The condition POWER FAULT in OR with HB alarm can be assigned to an alarm or identied in the state of a bit in variables
STATUS, STATUS1, STATUS2 and STATUS3.
In STATUS3 you can identify the condition that activated the POWER_FAULT alarm.
POWER_FAULT diagnostics is congurable with parameter hd.2, with which even just a part may be enabled
SSR SHORT SSR module in short circuit
NO VOLTAGE power failure or interrupted fuse
NO CURRENT due to SSR module open or fuse or load interrupted
For alarm HB (load partially interrupted), refer to the specic section of this manual.
The default value of the maximum limit or ammeter full-scale depends on the model:

VOLTAGE VALUE ON LOAD
RMS voltage is read in variable Ld.V of each zone. If zone 1 has a 3-phase load, variable Ld.V.t in the rst zone
contains the average RMS value of voltages on three load L1, L2 and L3.
Voltage on the load is acquired with sampling on each cycle, 20ms at 50Hz (16.6ms at 60Hz). Accuracy is better than 1%.
If the option VLOAD is not present, the Load RMS voltage value is calculated from the line voltage and from the output
power values.

LINE VOLTAGE VALUE
There are the following parameters if zone 1 has a single-phase load:
I.tV1 instantaneous voltmeter value of line
I.VF1 ltered voltmeter value
o.tV1 voltmeter input offset correction
Ft.tV voltmeter input digital lter
There are the following parameters if zone 1 has a 3-phase load:
I.tV1, I.tV2 and I.tV3, the instantaneous voltmeter value on line L1, L2 and L3, respectively.
RMS voltage values refer to voltage between 1/L1 and 3/L2 terminals.
I.VF1, I.VF2 and I.VF3 ltered voltmeter value on line L1, L2 and L3
o.tV1, o.tV2 and o.tV3 voltmeter input offset correction on line L1, L2 and L3.
Each phase has a voltage presence check that shuts off the module in case of incorrect values.
3-phase loads have an imbalance diagnostic, with consequent shut-down of the load and signal via LEDs.
A “voltage status” parameter contains information on the status of line voltage, including mains frequency identied 50/60Hz.
3-phase loads have diagnostics for correct phase connection, lack of a voltage, or imbalance of the three line voltages.
