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 documentation 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.

CHARACTERISTICS OF PERSONNEL

All personnel operating, installing, or doing maintenance on the instrument must be expert, trained, aware and mature,

able to reliably and correctly interpret this manual. This manual CANNOT make up for cultural or intellectual insufciencies. Therefore, all personnel interacting with the instrument must:

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:

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 addresses 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.

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.

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, where:

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.

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.

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.

POWER ON LOAD

Power on the load in each zone is read in variable Ld.P and the corresponding energy value in variables Ld.E1 and Ld.E2.

These energy values show the value accumulated since the rst power on or since the last reset (commands at bits 114 and

115); non-volatile memory is updated at power off. Load impedance in each zone is read in variable Ld.I. If zone 1 has a 3-phase load, variable Ld.P.t shows power and Ld.I.t total impedance, the corresponding energy value in variables Ld.E1.t and Ld.E2.t.

Note that for loads such as IR lamps, impedance can vary greatly based on the power transferred to the load.

AUXILIARY ANALOG INPUTS (LIN/TC)

The GFW has 4 inputs defined as auxiliary (IN2 for zone 1, IN3 for zone 2, IN4 for zone 3, IN5 for zone 4) to which TC or linear temperature sensors can be connected. The presence of these inputs is optional

Input values are available in variables In.2/In.3/In.4/In.5 and can be read or used to activate assigned alarm signals.

When an auxiliary input is present, you have to dene the following parameters:

- sensor type (AI.2, AI.3, AI.4, AI.5);

- its function (tP.2); (only for IN2 input)

- decimal point position (dP.2, HS.3 – LS.3, HS.4 – LS.4, HS.5 – LS.5);

- scale limits (HS.2 – LS.2);

- offset correction value (oFS.2, oFS.3, oFS.4, oFS.5).

If the sensor is a thermocouple, the minimum and maximum limits can be dened in the specic scale of the sensor

used. The range of values settable for alarm setpoints depends on these limits.

There is also a digital lter (Flt.2, Flt.3, Flt.4, Flt.5,) that can be used to reduce noise on the input signal.

ALARMS

GENERIC ALARMS AL1, AL2, AL3 and AL4

Four generic alarms are always available and can perform various functions. Typically, alarm AL.1 is defined as minimum and AL.2 as maximum. These alarms are set as follows:

- select the reference variable to be used to monitor the value (parameters A1.r, A2.r, A3.r and A4.r): the origin of the variable can be chosen from the process variable PV (generally linked to the main input), the ammeter input, the voltmeter input, the auxiliary analog input, or the active setpoint.

- set the value of the alarm setpoint (parameters AL.1, AL.2, AL.3 and AL.4). This value is used for comparison with the reference variable value: it can be absolute or indicate a shift from the variable in case of deviation alarm.

- set the hysteresis value for the alarm (parameters Hy.1, Hy.2, Hy.3 and Hy.4): the hysteresis value defines a band for safe re-entry of the alarm condition: without this band, the alarm would be deactivated as soon as the reference variable re-entered the setpoint limits, with the possibility of generating another alarm signal in the presence of oscillations of the reference signal around the setpoint value.

- select alarm type:

- absolute/deviation: if the alarm refers to an absolute value or to another variable (for example, to the setpoint).

- direct/reverse: if the reference variable exceeds the alarm setpoint in the “same direction” as the control action or not. For example, the alarm is direct if the reference variable exceeds the upper setpoint value during heating or assumes values below the lower setpoint during cooling. In the same manner, the alarm is reverse if the reference variable assumes values below the lower setpoint during heating or exceeds the setpoint during cooling.

- normal/symmetrical: if band value is subtracted or added, respectively, to/from the upper and lower limit of the alarm setpoints or indicates a higher and lower band compared to the alarm setpoint.

- with/without disabling at switch-on: if you want to check the reference variable value at system switch-on or wait until the variable enters the control window.

- with/without memory: if the alarm signal persists even when the cause has been eliminated or stops when the variable returns to normal values.

The above concepts are better explained in the following figures:

LBA ALARM (Loop Break Alarm)

This alarm identifies incorrect functioning of the control loop due to a possible load break or to a short circuited or reversed probe.

With the alarm enabled (parameter AL.n), the instrument checks that in condition of maximum power delivered for a settable time (Lb.t) greater than zero, the value of the process variable increases in heating or decreases in cooling: if this does not happen, the LBA alarm trips. In these conditions, power is limited to value (Lb.P).

The alarm condition resets if the temperature increases in heating or decreases in cooling.

HB ALARM (Heater Break Alarm)

This type of alarm identifies load break or interruption by measure the current delivered by means of a current transformer. The following three fault situations may occur:

- delivered current is lower than nominal current: this is the most common situation, and indicates that a load element is breaking.

- delivered current is higher than nominal current: this situation occurs, for example, due to partial short circuits of load elements.

- delivered current remains significant even during periods in which it should be zero: this situation occurs in the presence of pilot circuits for the short-circuited load or due to relay contacts soldered together. In these cases, prompt action is very important to prevent greater damage to the load and/or to the pilot circuits. In standard configuration, output SSR is associated to heating control in zone 1, obtained by modulating electrical power with the ON/OFF control based on the set cycle time. The current read performed during the ON phase identifies an anomalous shift from the rated value due to a load break (first two fault situations described above), while the current read performed during the OFF phase identifies a break in the control relay, with consequent output always active (third fault situation). The alarm is enabled by means of parameter AL.n; select the type of function you want by means of parameter Hb.F:

Hb.F=0: alarm activates if the current load value is below the setpoint value set in A.Hbx while the SSR control output is ON. Hb.F=1: alarm activates if the current load value is above the setpoint value set in A.Hbx while the SSR control output is OFF. Hb.F=2: alarm activates by combining functions 0 and 1, considering the setpoint of function 1 as 12% of the ammeter full

scale defined in H.tAx. Hb.F=3 or Hb.F=7 (continuous alarm): alarm activates due to a load current value below the setpoint value set in A.Hbx; this alarm does not refer to the cycle time and is disabled if the heating (cooling) output value is below 3%. Setting A.Hbx = 0 disables both types of HB alarm by forcing deactivation of the alarm state. The alarm resets automatically if its cause is eliminated. An additional configuration parameter for each zone, related to the HB alarm is: Hb.t = delay time for activation of HB alarm, understood as the sum of times for which the alarm is considered active. For example, with:

- Hb.F = 0 (alarm active with current below setpoint value),

- Hb.t = 60 sec and cycle time of control output = 10 sec,

- power delivered al 60%, the alarm will activate after 100 sec (output ON for 6 sec each cycle); if power is delivered at 100%, the alarm will activate after 60 sec. If the alarm deactivates during this interval, the time sum is reset. The delay time set in Hb.t must exceed the cycle time of the SSR output. If zone 1 has a 3-phase load, you can set three different setpoints for the HB alarm: A.Hb1= alarm setpoint for line L1 A.Hb2= alarm setpoint for line L2 A.Hb3= alarm setpoint for line L3

FUNCTION: HB ALARM SETPOINT SELF-LEARNING

This function permits self-learning of the alarm setpoint. To use this function, you first have to set parameter Hb.P, which defines the percentage of current compared to rated load below which the alarm trips. The function can be activated via control from serial line, digital input (see parameter dIG or dIG.2) or by key. When the Teach-in function is activated in modes ZC, BF and HSC, the RMS current value in conduction ON multiplied by parameter Hb.P determines the HB alarm setpoint. When the Teach-in function is activated in mode PA, the existing RMS current value is shown at 100% of power, which, multiplied by parameter Hb.P, determines the HB alarm setpoint.

For IR lamps (see parameter Hd.5 option +128), the function activates automatic reading of the power/current curve useful for determining the HB alarm setpoint. Automatic reading of the power/current curve takes place with the following sequence:

- softstart at maximum power (default 100%), 5 sec. delay

- reduction of power to 50%, 30%, 20%, 15%, 10%, 5%, 3%, 2%, 1%, between every value 5 sec. delay

- return to normal operation. Maximum conduction value in this phase can be limited by means of the PS.Hi parameter. If requested, MUST be activated only with Hd.6=0 (the required Hd.6 value can be set only after calibration).

Overheat alarm

Each power module has one temperature sensor for the internal heat sink and two additional temperature sensors connected to the LINE and LOAD terminals. Temperature levels are shown in variables INNTC_SSR, INNTC_LINE and INNTC_LOAD. The over_heat alarm trips when at least one of the temperatures exceeds a set threshold. This condition may be caused by obstructed ventilation slits or by a stopped cooling fan. With the over_heat alarm active, the control disables control outputs OUT1, OUT2 and OUT3. There is an additional maximum temperature protection that hardware disables the SSR controls.

FUSE_OPEN AND SHORT_CIRCUIT_CURRENT ALARMS

The FUSE_OPEN alarm trips when the (optional) internal high-speed fuse opens or when the (optional) electronic fuse switches off.

The SHORT_CIRCUIT_CURRENT alarm trips when peak current on the load exceeds the maximum limit (corresponding to twice the rating) during the softstart ramp or at first power-on (with softstart ramp disabled).

If configured (Fr.n other than zero), the device restarts automatically in softstart for a maximum of Fr.n attempts, beyond which it remains deactivated while awaiting manual reset with front panel key BUT or with the control via serial (bit 109).

ELECTRONIC FUSE OPTION

The electronic fuse avoids the use of a high-speed fuse to protect the controller. In case of a short circuit on the load, the electronic fuse switches off immediately and the relative FUSE_OPEN alarm activates.

- The electronic fuse DOES NOT replace any of the safeties on the system (such as magnetothermic switches,

delay fuses, etc.).

- The electronic fuse protects the controller (and therefore also the load) by replacing the high-speed fuse needed to protect the control SCRs against faults (without creating any additional cost to replace the fuse and reducing

machine downtime).

- The electronic fuse has 2 function states:

- Normal (On-Off control of load power)

- Fuse-Open: GFW is open (a short occurred during normal operation).

OUTPUTS

The modular power controller has high flexibility in the assignment of functions to the physical outputs. As a result, the instrument can be used in sophisticated applications. A function is assigned to each physical output in two steps: first assign the function to one of internal reference signals rL.1 .. rL.6, and then attribute the reference signal to parameters out.1 .. out.10 (corresponding to physical outputs OUT1 .. OUT10). In standard configuration, physical outputs Out1, Out2, Out3 perform the heating control function (Heat) for zone 1, zone 2, and zone 3, respectively; value 0 (function HEAT) is assigned to reference signals rL.1 in each zone, and the following values to the output parameters: out.1=1 (output rL.1 zone 1), out.2=2 (output rL.1 zone 2), out.3=3 (output rL.1 zone 3). Physical outputs Out5, Out6, Out7, Out8 are optional, and the type (relay, logic, continuous or triac) is defined by the order code. In standard configuration, these outputs perform the cooling control function (Cool) for zone 1, zone 2, and zone 3, respectively. In this configuration, value 1 (function COOL) is assigned to reference signals rL.2 in each zone, and the following values to the output parameters: out.5=5 (output rL.2 zone 1), out.6=6 (output rL.2 zone 2), out.7=7 (output rL.2 zone 3). Relay outputs Out9 and Out10 are always present, programmable by means of parameters out.9 and out.10, to which available alarm signal functions are assigned by means of the four reference signals rL.3, rL.4, rL.5, rL.6 in each zone. Standard configuration has the following assignments:

- reference signals: rL.3=2 (function AL1), rL.4=3 (function AL2), rL.5=4 (function AL3) and rL.6=5 (function AL.HB or POWER_FAULT with HB alarm).

- output parameters: out.9 =17 and out.10 =18. In this way, the state of output physical Out9 is given by the logic OR of AL1, AL3 in each zone, and the state of output Out10 is given by the logic AND of AL2, AL.HB in each zone. Each output can always be disabled by setting parameter out.x = 0. The state of outputs Out1,...,Out10 can be acquired by serial communication by means of bit variables. The following additional configuration parameters are related to the outputs: Ct.1 = cycle time for output rL.1 for heating control (Heat) Ct.2 = cycle time for output rL.2 for cooling control (Cool) rEL = alarm states AL1, AL2, AL3, AL4 in case of broken probe, Err, Sbr

Set gradient

The “Set gradient” function sets a gradual variation of the setpoint, with programmed speed, between two defined

values. If this function is active (

g.sp other than 0), at switch-

on and at auto/man switching the initial setpoint is assumed equal to the PV, and the local or selected set is reached with set gradient. Every variation of set, including variations of the

local setpoint, is subject to the gradient.

The value of remote setpoint SP.rS is not saved in eeprom. The set gradient is inhibited at switch-on when selftuning is enabled.

PID HEAT/COOL CONTROL

The controller can manage a heating output and a cooling output in a completely independent manner. Heating and cooling parameters are described below. Parameters for PID (proportional band, integral and derivative time) control are typically calculated by means of Autotuning and Selftuning functions.

Proportional action: action in which contribution to output is proportional to deviation at input (deviation = difference between controlled variable and setpoint Derivative action: action in which contribution to output is proportional to rate of variation input deviation. Integral action: action in which contribution to output is proportional to integral of time of input deviation.

Control actions

Increasing the proportional band reduces oscillation but increases deviation. Reducing the proportional band reduces deviation but causes oscillation of the controlled variable (excessively low proportional band values make the system unstable). An increase in Derivative Action corresponds to an increase in Derivative Time, reduces deviation, and prevents oscillation up to a critical Derivative Time value, beyond which deviation increases and there are prolonged oscillations. An increase in Integral Action corresponds to a decrease in Integral Time, tends to annul deviation between the controlled variable and the setpoint at rated operating speed. If the Integral Time value is too long (weak Integral Action), there may be persistent deviation between the controlled variable and the setpoint. For more information on control actions, contact GEFRAN.

CONTROLS

Control output with only proportional action in case of proportional heating band superimposed on cooling band.

Output with separate band Output with superimposed band

Heat/cool control with separate or superimposed band

This control mode (enabled with parameter Ctr = 14) asks you to specify cooling type. The PID cooling parameters are then calculated based on heating parameters in the ratio specified (ex: C.ME = 1 (oil), H_Pb = 10, H_dt =1, H_It = 4 implies: C_Pb = 12.5, C_dt = 1 , C_It = 4) Apply the following values when setting cycle times: Air T Cool cycle = 10 sec. Oil T Cool cycle = 4 sec. Water T Cool cycle = 2 sec.

NB.: Cool parameters cannot be changed in this mode.

AUTOMATIC / MANUAL CONTROL

By means of the digital input function you can set the controller in MAN (manual) and set the control output to a constant value changeable by means of communication. When returning to AUTO (automatic), if the variable is within the proportional band, switching is bumpless.

With this function (available on models with CV diagnostics option), you can run a correction of power delivered in manual based on the reference line voltage (riF). The % value of the (Cor) is freely settable and acts in inverse proportion. The function is activated/deactivated by means of parameter SP.r.

Example: with the following settings: Cor = 10%; riF = 380; SP.r = value + 8; instrument in manual; line voltage 380 VAC, manual power set at 50%, following a 10% increase in line voltage, 380V + 10% (380V) = 418V, there is a decrease in set manual power equal to the same % of change: 50% - 10% (50%) = 45%. To use this function, the controller must have a CT (current transformer) and a VT (voltage transformer). N.B.: the % change in manual power is limited to the value set in parameter “Cor”. The maximum manual power correction is limited to ± 65%.

HOLD FUNCTION

The process variable value and the setpoints remain “frozen” for the time the digital input is active. By activating the digital input with the Hold function when the variable is at values below the setpoint, a setpoint memory reset de-energizes all energized relays and resets all memory latches.

AUTOTUNING

Enabling the autotuning function blocks the settings of the PID parameters. Autotuning continues to measure the system oscillations, seeking as quickly as possible the PID parameter values that reduce the oscillation; it does not intervene if the oscillations drop to values below 1.0% of the proportional band. It is interrupted if the setpoint is changed, and resumes automatically with a constant setpoint. The calculated parameters are not saved; if the instrument is switched off the controller resumes with the parameters programmed before autotuning was enabled. Autotuning terminates the procedures with switching to manual.

Enabling the autotuning function blocks the settings of the PID parameters. It can be two types: continuous or one shot.

Continuous autotunìng is enabled with parameter Stu (values 1, 3, 5); it continues to measure the system oscillations, seeking as quickly as possible the PID parameter values that reduce the oscillation; it does not intervene if the oscillations drop to values below 1.0% of the proportional band. It is interrupted if the setpoint is changed, and resumes automatically with a constant setpoint. The calculated parameters are not saved if the instrument is switched off, in case of switching to manual or disabling the code in configuration, and controller resumes with the parameters programmed before autotuning was enabled. The calculated parameters are saved when the function is enabled via digital input or via A/M key (start /stop) at stop.

One-shot autotuning can be activated manually or automatically with parameter Stu (as can be seen on the table, the values to be set depend on enabling of Selftuning or Softstart). It is useful for calculating PID parameters when the system is in the vicinity of the setpoint; it produces a variation on the control output of a maximum of ± 100% of the current control power limited by h.PH - h.PL (heat), c.PH - c.PL (cool) and assesses the effects in overshoot over time. The calculated parameters are saved. Manual activation (code Stu = 8, 10, 12) by setting the parameter directly or via digital input or key. Automatic activation (code Stu = 24, 26, 28 with error range of 0.5%) when the PV-SP error exceeds the defined range (programmable at 0.5%, 1%, 2%, 4% of full scale).

Activation is inhibited if PV <5% or PV >95% of input scale.

NB: at switch-on after selftuning, after switching to MANUAL, after software shutdown or after a setpoint change, automatic activation is inhibited for an interval equal to five times the integral time, with a minimum of 5 minutes. An identical interval has to lapse after a one-shot run.

Integral time It = 1,5 x T Derivative time dt = It/4 E) Switch the controller to manual, set the calculated parameters (activate the PID control by setting a cycle time for relay outputs, if any), switch to automatic. F) To assess parameter optimization, change the setpoint value if possible and check temporary behavior. If oscillation persists, increase the value of the proportional band; if response is too slow, decrease the value.

The procedure runs automatically until termination. At termination, the new PID parameters are saved: proportional band, integral and derivative times calculated for the current action (heat or cool). In case of double action (heat + cool), the parameters for the opposite action are calculated by maintaining the initial ratio between the parameters (example: Cpb = Hpb * K; where K = Cpb / Hpb when selftuning is started). At termination, the Stu code is automatically cancelled. Note: The procedure does not start if temperature exceeds the setpoint for heat control, or is below the setpoint for cool control. In this case, the Stu code is not cancelled. It is advisable to enable the LEDs to signal selftuning state. By setting parameter Ld.St = 4 on the Hrd menu, the appropriate LED will light up or flash when selftuning is active.

SELFTUNING

This function is valid for single-action (either heat or cool) systems and for double-action (heat/cool) systems. Selftuning is activated to calculate the best control parameters when starting the process. The variable (example: temperature) must be the one assumed at zero power (room temperature). The controller supplies the maximum power set until reaching an intermediate point between starting value and the setpoint, then resets power. The PID parameters are calculated by evaluating superelongation and the time needed to reach the peak (N.B.: This action is not considered in ON/OFF control). When the function is completed, it disengages automatically, and the control proceeds to reach the setpoint.

Softstart is an alternative to selftuning and is activated after each instrument switch-on. Softstart is reset when switching to manual.

SOFTWARE SHUTDOWN

Running the software shutdown procedure causes the following:

1) Reset of Autotuning, Selftuning and Softstart.

2) Digital input enabled only if assigned to SW shutdown function.

3) In case of switch-on after SW shutdown, any ramp for the set (set gradient) starts from the PV.

4) Outputs OFF: except for signals them of reference rL.4 and rL.6 that they come forced ON

5) Reset of HB alarm.

6) Reset of LBA alarm.

7) The Heat and Cool bit on the state word STATUS and POWER are reset.

8) At shutdown, the current power is saved. At switch-on, integral power is recalculated as the difference between saved power and proportional power; this calculation is defined as “desaturation at switch-on.”

9) In case of Geflex, the state of alarms (AL1...AL4, ALHBTA1...ALHBTA3) is reset.

9) Alarms AL 1… AL 4 can be enable or disable through the parameter oFF.t.

FAULT ACTION POWER

You can decide what power to supply in case of broken probe.

FAP is the reference power for parameter FAP.

Average power is the average power calculated in the last 300 sec.

The alarm reset and reference power update take place only at switch-on or after a setpoint change.

The alarm is not activated if the control (Ctr) is ON/OFF type, during Selftuning and in Manual.

OTHER FUNCTIONS

POWER ALARM

The alarm signals any power changes (OuP) after the process variable (PV) has stabilized on the setpoint (SP). The

time beyond which the process variable is considered stable is 300 sec.

The reference power update take place only at switch-on or after a setpoint change.

If the process variable leaves the stabilization band after the first stabilization, this does not influence the alarm.

In case of SBR:

- if the PV has not yet stabilized, either the average power over the last 5 minutes or FAP power is supplied (depending on

the setting of the HOT parameter).

- if the PV has stabilized the average power over the last 5 minutes is supplied.

Function:

If necessary, assign an output (rL.2...6) for the power alarm.

Set the band (b.ST) within which the process variable is considered stable after 300 sec. have elapsed.

Set the band (b.PF) outside which the alarm is activated after time PF.t has elapsed.

The reference power is the active power after 300 sec. have elapsed.

The alarm reset and reference power update take place only at switch-on or after a setpoint change.

SOFTSTART FOR PREHEATING

This function lets you deliver a settable power (So.P) for time (SoF), after which normal control is resumed by means of PID control. Activation is only at switch-on, with manual-automatic switching during Softstart (the time restarts from 0), and if the process variable is below setpoint SP.S.

From SW version 2.02:

With softstart time SoF = 0, preheat condition PV <SP.S with settable power SO.P is continuously checked.

SSR CONTROL MODES

ON Modality

The GFW has the following power control modes:

- PA modulation via variation of phase angle

- ZC, BF, HSC modulation via variation of number of conduction cycles with zero crossing trigger. PA phase angle: this mode controls power on the load via modulation of the phase angle. ZC zero crossing: this type of operation reduces EMC emissions. This mode controls power on the load via a series of conduction ON and non conduction OFF cycles. The cycle time is constant and can be set from 1 to 200 sec (or from 0.1 to 20.0 sec).

BF burst ring: this mode controls power on the load via a series of conduction ON and non conduction OFF cycles. The ratio of the number

of ON cycles to OFF cycles is proportional to the power value to be supplied to the load. The repeat period or cycle time is kept to a minimum for each power value.

Parameter bF.Cy denes the minimum number of conduction cycles, settable from 1 to 10.

In case of 3-phase load without neutral or closed delta, BF.Cy >= 5 has to be set to ensure correct operation (balancing of current in the 3 loads).

HSC Half Single Cycle: this mode corresponds to a BF that includes ON and OFF half-cycles. It is useful for reducing icker with short-wave

IR loads (and is applied only to single-phase or 3-phase with neutre or open delta loads).

Start mode is set with parameter Hd.5 Control of maximum rms current (whose value is set in parameter Fu.tA) can always be enabled with parameter Hd.5 in every power-on mode. The cycle time can be set with two different resolutions in seconds or tenths of a second based on the type of heat or cool function assigned to outputs rL1 and rL2. The use of short cycle times (< 2-3 sec) is always recommended in case of control with SSRs.

DELAY TRIGGERING

In ring modes ZC and BF, with inductive loads, this function inserts delay triggering in the rst cycle.

The delay is expressed in degrees settable in parameter dL.t, from 0 to 90 degrees. The function is enabled with parameter Hd.5 (+32). The function activates automatically if there are OFF conditions for a time exceeding the one settable in dL.oF (if =0 the function is as if disabled).

NB: In case of a 3-phase load, you can set a different value from parameter PS.tA for each zone (ex. to control an unbalanced 3-phase load).

SOFTSTART or START RAMP

This type of start can be enabled either in phase control or pulse train mode and acts via control of the conduction angle. It is enabled with parameter Hd.5. The softstart ramp starts from a zero conduction angle and reaches the angle set in parameter PS.HI in the time set in parameter PS.tm, from 0.1 to 60.0 sec.

With parameter Hd.5 (+64), you can congure a linear softstart in power, i.e., starting from zero you reach the power

value corresponding to the maximum conduction angle set in PS.HI. Softstart ends before the set time if power reaches the corresponding value set in manual control or calculated by PID. Control of maximum peak current can be enabled with parameter Hd.5 during the ramp phase; peak value is settable

in parameter PS.tA. This function is useful in case of short circuit on the load of loads with high temperature coefcients to automatically adjust start time to the load. The softstart ramp activates at the rst start after power-ON and after a software reboot. It can be reactivated via

software control by writing bit 108 or automatically if there are OFF conditions for a time exceeding the one settable in PS.oF (if =0 the function is as if disabled). The ramp can also be enabled with parameter Hd.5 (+256) after a software shutdown, i.e., zero is reached in the set time from delivered power.

FEEDBACK MODES

The GFW has the following power control modes: V-voltage V

-squared voltage I-current I

-squared current P-power A control mode is enabled with parameter Hd.6.

Voltage feedback (V) To keep voltage on the load constant, this compensates possible variations in line voltage with reference to the rated voltage saved in riF.V. (expressed in Vrms). The voltage value maintained on the load is (ref.V*P%_pid_man/100) and is indicated in the Modbus 757 register.

Voltage feedback (V

)

To keep voltage on the load constant, this compensates possible variations in line voltage with reference to the rated voltage saved in riF.V. (expressed in Vrms). The voltage value maintained on the load is (rif.V*

V (P%_pid_man/100)), and is indicated in the Modbus 757 register.

Current feedback (I) To keep current on the load constant, this compensates possible variations in line voltage and/or variations in load impedance with reference to the rated current saved in riF.I. (expressed in Arms). The current value maintained on the load is (rif.I*P%_pid_man/100), and is indicated in the Modbus 757 register.

Current feedback (I

)

To keep current on the load constant, this compensates possible variations in line voltage and/or variations in load impedance with reference to the rated current saved in riF.I. (expressed in Arms). The current value maintained on the load is (rif.I*

V (P%_pid_man/100)), and is indicated in the Modbus 757 register.

Power feedback P

To keep power on the load constant, this compensates both variations in line voltage and variations in load impedance with reference to the rated power saved in riF.P. (expressed in kWatt). The current value maintained on the load is (rif.P*P%_pid_man/100), and is indicated in the Modbus 757 register.

IMPORTANT!

Feedback calibration can be activated from the digital input (parameters DIG and DIG.2) or by serial control (ref. bit113), and if requested MUST be activated only with Hd.6=0 (the required Hd.6 value can be set only after calibration) and preferably with maximum power on the load (ex. P_man or P_pid at 100%). If you change function mode (PA, ZC, BF, HSC), you have to re-run the Feedback calibration procedure.

Voltage V (or current I or power P) feedback corrects the % of conduction with a maximum settable value in parameter Cor. V (or Cor.I or Cor.P).

For non-linear loads (ex.: Super Kanthal or Silicon Carbide) the automatic calibration procedure is NOT NECESSARY. Set the value of parameters ref.V, ref. I, ref. P based on the specic nominal of the load shown on the data-sheet (ref. GFW Installation Guide).

This function acts by enabling the control to search for the most appropriate input combinations.

Example 1: 4 loads 380V- 32A (zone 1), 16A (zone 2), 25A (zone 3), 40A (maximum current is 73A in case of simultaneity of conduction). Current limit I.HEU=50A. The following combinations of conduction are possible:

(to dene the number of combinations, remember that the

combinations without repetitions are = n! / (k!*(n-k)!) ) I1+I2 = 48A I1+I3 = 57A I2+I3 = 41A I1+I2+I3 = 73A

The combinations corresponding to current values below the limit value are: I1+I2 = 48A I2+I3 = 41A The one with lower current is given by zone 2 and zone 3.

In the single cycle time for the enabled zones, the delivery of power may be reduced to respect the maximum current limit. The time distribution for activation of the zones is calculated at the start of each cycle: Ptot = P1+ P2 (if P2>P3) + P3 (if P3>P2) Simultaneity is allowed for zones 2 and 3.

If P1= 100%, P2= 100%, P3= 100% Ptot=200%; since Ptot>100%, the conduction time of the zone x is obtained by Px * (100/Ptot) P1,2,3 delivered = 100%*0.5 = 50%

If P1= 100%, P2= 50%, P3= 0% Ptot=150%; since Ptot>100%, the conduction time of the zone x is obtained by Px * (100/Ptot) P1 delivered = 100%*0.66 = 67% P2 delivered = 50%*0.66 = 33% P3 delivered = 0%*0.66 = 0%

HEURISTIC CONTROL POWER

It is useful to be able to limit the delivery of total power to the loads in order to avoid input peaks from the single-phase power line. This condition occurs during switch-on phases when the machine is cold; the demand for heating power is 100% until temperatures near the setpoint are reached. It is also useful to avoid simultaneity of conduction when there is ON-OFF modulation for temperature maintenance. The cycle time must be identical for all zones; the power percentage for each zone is limited to that necessary to

maintain current within set limits.

HETEROGENEOUS POWER CONTROL

This function matches that of a thermal cutout that disconnects the load based on instantaneous input. The load is disconnected based on a preset priority.

Virtual instrument control is activated by means of parameter hd.1. By setting parameters S.In and S.Ou you can enable the writing of some parameters via serial line, set the value of inputs and the state of outputs. You have to enable alarm setpoints AL1, ..., AL4 when write operations are continuous, and you don’t have to keep the last value in eeprom. Enabling the PV input means being able to exclude the local Tc or RTD acquisition and replace it with the value written in the register VALUE_F. Enabling digital input IN lets you set the state of this input, for example to run MAN/AUTO switching with the writing of bit 7 in the register V_IN_OUT. Likewise, you can set the on/off state of outputs OUT1, ..., OUT10 and of the LEDs by writing bits in the register V_IN_OUT.
