VAC to 600VAC.
The section contains general information and
warnings to be read before installing, configuring and
using the controller.
The command input is configurable and accepts 0-10V, 0/4-20mA
signals, potentiometer, logic signals, including with PWM modes
for cost effective solutions.
The device can also be operated via Modbus RTU serial communication, with IN/OUT chain connections facilitated by plug-in
RJ10 (telephone) connectors.
The several trigger modes are software configurable and provide:
- ZC: Zero Crossing constant cycle time (settable in range
1-200sec), for conventional loads
- BF: Burst-Firing, Zero crossing with optimized minimum cycle
time, for systems with low thermal inertia, medium-wave IR lamps
- HSC: Half Single Cycle Zero Crossing corresponds to Burst
Firing that manages single semi-cycles of conduction or stop
cycles, useful for short-wave IR lamps, reduces flickering and limits generation of EMC noise on the power line (applied only to
single-phase load or open delta).
- PA: Phase angle control, useful for short-wave IR lamps, tran-
sformer primaries. Completely eliminates flickering of load filaments, but generates EMC noise on power line (harmonics).
Soft Start and soft stop ramp functions can be assigned to these
controls with limitation of current peaks and/or maximum RMS
current level.
Thanks to sophisticated Hardware and Software solutions, you
can precisely control different types of loads.
Phase angle control (the only control method that completely eliminates IR lamp flickering), matched with current, voltage, or load
power feedback functions, allows the easy use of “critical” appli-
cations such as (for example), special resistors such as special
Super Khantal™ heating elements, Silicon Carbide resistors, or
transformer primaries either single-phase or triphase.
1.2

2 • INSTALLATION AND CONNECTION
This section contains the instructions needed for
correct installation of GTF controllers on the
machine/host system control panel and for correct
connection of the power supply, inputs, outputs and
interfaces.
CAREFULLY READ THE FOLLOWING WARNINGS
BEFORE INSTALLING THE INSTRUMENT!
Disregard of such warnings could create
electrical safety and electromagnetic
compatibility problems, as well as void the
warranty.
2.1
Electrical power supply
• the controller DOES NOT have an On/Off switch: the user
must install switch/isolator conforming to safety requisites (CE mark) to cut off the power supply up-line of the controller.
The switch must be installed in the immediate vicinity of the
controller in easy reach of the operator.
A single switch can be used for multiple devices.
2.3
Recommendations for Correct Installation
for purposes of EMC
2.3.1
Instrument power supply
• The power supply for the electronic instrumentation on the
panels must always come directly from a cut-off device with
fuse for the instrument part.
• Electronic instrumentation and electromechanical power
devices such as relays, contactors, solenoids, etc., MUST
ALWAYS be powered by separate lines.
• When the power supply line of electronic instruments is
heavily disturbed by switching of thyristor power groups or
by motors, you should use an isolation transformer only for
the controllers, grounding its sheathing.
• It is important for the system to be well-grounded:
- voltage between neutral and ground must not be > 1V
- Ohmic resistance must be < 6Ω;
• If the grid voltage is highly unstable, use a voltage stabilizer.
• In proximity of high-frequency generators or arc welders,
use adequate grid filters.
• The power supply lines must be separate from instrument
input and output lines.
•Supply from Class II or from limited energy source
* the earth connection must be made with a specific lead.
• if the product is used in applications with risk of harm to
persons or damage to machines or materials, it MUST be
equipped with auxiliary alarm devices.
It is advisable to provide the ability to check for tripped alarms
during regular operation.
DO NOT install the product in rooms with hazardous
(inflammable or explosive) atmosphere; it may be connected
to elements that operated in such atmosphere only by means
of appropriate interfaces that conform to current safety
standards.
2.2
Notes on electrical safety and
electromagnetic compatibility:
2.2.1 CE MARKING: EMC
(electromagnetic compatibility) conformity
in compliance with Directive 2004/108/CE and following
modifications.
Series GTF controllers are mainly intended for industrial
use, installed on panels or control panels of production
process machines or systems.
For purposes of electromagnetic compatibility, the most
restrictive generic standards have been adopted, as shown
on the table.
2.2.2
LV (low voltage) conformity
in compliance with Directive 2006/95/CE.
EMC compliance has been verified with respect to
the information in Tables 1 and 2.
4
2.3.2
Input and output connections
Before connecting or disconnecting any connection, always check
that the power and control cables are isolated from voltage
Appropriate devices must be provided: fuses or automatic
switches to protect power lines.
The fuses present in the module function solely as a protection
for the GTF semiconductors.
• Connected outside circuits must be doubly isolated.
• To connect analog inputs, strain gauges, linears, (TC, RTD),
you have to:
- physically separate the input cables from those of the
power supply, outputs, and power connections.
- use braided and shielded cables, with sheathing grounded
at a single point.
2.3.3
Installation notes
Use the extra-rapid fuse indicated in the catalogue according to
the connection example equipped.
- Moreover, the applications with solid-state units require a safety automatic switch to section the load power line.
To ensure maximum reliability, the device must be correctly
installed in the panel in such a way as to obtain adequate heat
exchange between the heat sink and the surrounding air under
conditions of natural convection..
Fit the device vertically (maximum angle 10° to the vertical
axis) see figure 3
• Vertical distance between a device and the panel wall
>100mm
• Horizontal distance between a device and the panel wall at
last 10mm
• Vertical distance between a device and the next one at last
300mm.
• Horizontal distance between a device and the next one at last
10mm.
80960D_MHW_GTF_05-2014_ENG
Check that the cable holder runners do not reduce these distances, in this case fit the cantilever units opposite the panel
so that the air can flow vertically on the dissipator without any
obstacles.
• dissipation of device thermic power with effects on installation
room temperature.
• thermal power dissipation with limits on installation room temperature.
• requires exchange with external air or an air conditioner to transfer dissipated power outside the panel.
• maximum limits of voltage and derived power of transients on
the line, for which the solid state power unit contains protective
devices (based on the model).
• presence of dispersion current in GTF in non-conducting state
(current of a few mA due to RC Snubber circuit to protect the
thyristor).
GEFRAN S.p.A. assumes no liability for any damage to persons or property deriving from tampering, from incorrect or improper use, or from
any use not conforming to the characteristics of
the controller and to the instructions in this User
Manual.

PERIODIC CLEANING
Every 6-12 months (depending on the dust level of the installation) blow a compressed air jet downward through the
upper rectangular cooling grilles (on the side opposite the fan).
This will clean the internal heat dissipater and the cooling fan.
IN CASE OF OVERHEAT ALARM
ATTENTION:
Before and during the inspection/maintenance cut power to the fan controller and verify that the system is isolated for operator safety.
If periodic cleaning does not eliminate the problem, do as follows:
a Remove the fan support grille by detaching the two support tabs
b Disconnect the fan connector from the board
c Check the condition of the fan
d Clean or replace the fan
Attention: check that the arrow (on the fan indicating the direction of air flow is pointing to the heat sink
e Insert the connector into the board
f Insert the fan support grille until it attaches
g Power up the device and check fan rotation when at least one load is on

NOTES: USE WITH INDUCTIVE LOADS AND TRANSFORMERS
a) b) c) d) e) f) g)
Connect a varistor (MOV) between each wire of the primary transformer and ground.
Varistor data: rated voltage 660Vrms,…, 1000Vrms; minimum energy 100J
The maximum current controllable by the device is less than the product’s rated value (see technical data).
In ZC and BF trigger mode, use the Delay-triggering function to limit peak magnetization current.
In PA trigger mode, use the Softstart function.
DO NOT use HSC trigger mode.
DO NOT connect RC snubbers in parallel to the transformer primary.
Select the inductive load using the Hd.1 parameter (ref. Software manual)
Trigger modes
The GTF has the following power control modes:
- modulation via variation of number of conduction cycles with zero crossing trigger.
- modulation via variation of phase angle.
Zero Crossing mode
This function eliminates EMC noise. This mode controls power on the load via a series of conduction ON and non
conduction OFF cycles.
ZC - constant cycle time (Tc ≥ 1 sec, settable from 1 to 200 sec)
Cycle time is divided into a series of conduction and non conduction cycles in proportion to the power value to
be transferred to the load.
Figure 36
For example, if Tc = 10sec, if the power value is 20% there is conduction for 2 sec (100 conduction cycles @ 50Hz)
and non conduction for 8 sec (400 non conduction cycles @ 50Hz).
BF - variable cycle time (GTT)
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 CT repeat period is kept to a minimum for each power value (whereas in ZC mode the period is always
fixed and not optimized).
26
80960D_MHW_GTF_05-2014_ENG
Figure 37
parameter defines the minimum number of conduction cycles settable from 1 to 10.
In the following example, the parameter = 2.
HSC - Half single cycle
This mode corresponds to Burst Firing that manages ON and OFF half-cycles. It is useful for reducing the
flickering of filaments with short/medium-wave IR lamp loads. With these loads, to limit operating current with
low power, it is useful to set a minimum power limit (for example, Lo.p = 10%).
NB:This mode is NOT allowed with inductive loads (transformers) It is used with resistive loads in single
phase, star with neutral, or open delta configuration.
Figure 38
Example of operation in HSC mode with power at 33 and 66%.
Phase angle (PA)
This mode controls power on the load via modulation of trigger angle q
Example: if power to be transferred to the load is 100%, q = 180°
or
if power to be transferred to the load is 50%, q = 90°

ADDITIONAL FUNCTIONS
Softstart
This type of start can be enabled either in phase control or pulse train mode and in zero-crossing mode (ZC, BF,
HSC).
In phase control, the increment of conduction angle q stops at the corresponding value of the power to be transferred
to the load.
Control of maximum peak current (useful in case of short circuit on the load or of loads with high temperature
coefficients to automatically adjust start time to the load) can be enabled during softstart. When the load shut-off time
(settable) is exceeded, the ramp is reactivated at the next power-on.
Figure 40
Example of firing ramp with phase Soft-Start
RMS current limit
The option for controlling the load current limit is available in all work modes.
If the current value exceeds the limit (settable in the nominal full-scale range) in mode PA the conduction
angle is limited, while in zero-crossing mode (ZC, BF, HSC) the cycle time conduction percentage is limited.
This limitation ensures that the RMS value (i.e., not the instantaneous value) of the load current does NOT
exceed the set RMS current limit.
Figure 41
Example of conduction angle limitation in PA mode to respect an RMS current limit below the nominal current of the
load.
28
80960D_MHW_GTF_05-2014_ENG
DT - “Delay triggering” (for ZC, BF control modes only)
Settable from 0° to 90°.
Useful for inductive loads (transformer primaries) to prevent current peak that in certain cases could
trip the high-speed fuses that protect the SCRs.

3.10
Digital input (PWM)
This digital input can be used to receive information on the % of power to be supplied to the load.
The signal can be generated by a controller or external plc via digital outputs (logic output for Gefran instrumentation).
This is obtained by alternating the output in ON for time TON with the output in OFF for time TOFF.
The sum of TON+TOFF is constant, and is called CycleTime.
CycleTime= TON+TOFF
The power level is given by the ratio = TON/ CycleTime and is normally expressed in %.
The GTF digital input automatically adapts to the cycle time from 0.03Hz to 100Hz and obtains the power % to be supplied to the load from the TON/(TON+TOFF) ratio.
Connection example:
Temperature control with Gefran 600 with D type logic output (out2) (cycle time: 0.1sec), logic output can drive max 3 GTF in series (preferable), connection allowed only if GTFs do not have interconnected GNDs (if so, make parallel connection).
To use Digital PWM the GTF can be ordered with the configuration 5 -x - M or must be configured with the parameter dIG (digital input) = 7 (see Fig. 46, 47).

4 • INSTALLATION OF THE SERIAL PORT
A network typically has a Master that “manages” communication by means of “commands,” and Slaves that carry out these
commands.
GTF modules are considered Slaves to the network master, which is usually a supervision terminal or a PLC.
It is positively identified by means of a node address (ID) set on rotary switches (tens + units).
A maximum of 99 GTF, modules can be installed in a serial network, with node address selectable from “01” to “99”
GTF modules have a ModBus serial (Optional)
The MODBUS RTU port 1 has the following factory settings (default):

4.1 “AUTOBAUD SERIAL 1” sequence
Function
Adapt the serial communication speed and parity of the GTF
modules to the connected supervision terminal or PLC.
The “RUN”and “STATUS” LEDs mentioned in the
procedure can vary its behavior based on on he
parameters Ld.1 e Ld.2
Procedure
1) Connect the serial cables for all modules on the network t
and to the supervision terminal.
2) Set the rotary switch on the GTF modules to be installed,
or on all modules present in case of first installation, to
position “0+0”.
3) Check that the “RUN” and “STATUS” LEDs flash at high
frequency (10Hz).
4) The supervision terminal must transmit a series of generic
“MODBUS” read messages to the network.
5) The procedure is over when all of the “RUN” and
“STATUS”LEDs on the GTF modules flash at a normal
frequency (2Hz) (if parameter 50 Ld.1 = 16 as default).
The new speed parameter is saved permanently in each GTF;
therefore, the “AUTOBAUD SERIAL” sequence does not have
to be run at subsequent power-ups.
When the rotary switch is turned, the green
“STATUS” LED stays on steadily for about 6
seconds, after which it resumes normal operation and
saves the address.
