2 Introduction
A thyristor unit is semiconductor device which acts as a switch formed by two thyristors in ant
parallel.
To switch on the alternating current the input signal will be on and the thyristor will switch off
at first Zero Crossing voltage with no input signal.
The benefits of thyristor units compared with elettromechanical contactors are numerouses:
no moving parts, no maintenance and capacity to switch very fast. Thyristors are the only
solution to control transformers and special loads that change resistance with temperature and
2.1 Advantages compared with analog thyristor unit
HE3 is an universal Thyristor unit, designed to control resistive or inductive loads including
three phase transformers. The electronic circuit is completely digital and is based on a
powerful microprocessor with high performance that allow the use in different ways:
•
Single cycle
•
Burst Firing with soft start and current limit
•
Delayed triggering
•
Phase Angle with soft start and current limit

0÷10Vdc
Potentiometer 10KΩ
SSR
Communication RS485 is a standard feature of HE3 this allows the use of many
information like: tension, current, power, load state and all the parameters for diagnostic
and configuration. Ulterior advantages of the digital system vs the analogical is the
flexibility and the possibility of implement special characteristics without change the
hardware. Several strategies can be implemented and selected through the configuration
parameters.
With CD-KP, you can have access to the configuration parameters without expose at the
dangerous voltage inside the cabinet and without stop the plant.

9.2 Critical Alarms
When a critical alarm is active, it stops the HE3 thyristor unit and activates the relative digital
output (terminal 15).
The parameter P001 ΑΛ_1 allows to visualize the state of these alarms (see par. 14.1).
9.2.1 Phase loss
This critical alarm is active when one of the three phases R-S-T is loss. The phase loss could
be also activated by an interrupted fuse.
For restart the thyristor unit, check the presence of the line voltage on the power terminals
L1, L2, L3 and check the state of the internal fuses, When the problem is solved before to
restart is necessary use the digital input: "Reset Alarm" (see par. 12.5).
9.2.2 External Alarm
This critical alarm is active when the Digital input 4 is configured like “External Alarm" and is
activated.
For restart the thyristor unit, you must disarm the external alarm. When the problem is solved
before to restart is necessary use the digital input: "Reset Alarm" (see par. 12.5).
9.2.3 Heat-sink Over temperature
This critical alarm is active when the thermal switch mounted on the heat-sink is activated.
For restart the thyristor unit, you must wait that the heat-sink returns at the safety
temperature. When the problem is solved before to restart is necessary use the digital input:
"Reset Alarm"
(see par. 12.5).
If this alarm becomes active, check if the indications described in the “par. 6” of this manual
are respected.
Caution: this procedure must be performed only by qualified persons.
25
9.3 Not Critical Alarm
The Not Critical Alarm, doesn’t stop the HE3 thyristor unit, but is possible to associate an
digital output at these alarms (see par. 12.6).
The parameter P002 ΑΛ_2 allows to visualize the state of these alarms (see par. 14.1).
9.3.1 SCR Short Circuit
This alarm is active when HE3 read the output current in absence of the input signal. This is
possible if there are a short circuit on the thyristor or if there are a wrong wiring of the load.
When the problem is solved is necessary use the digital input: "Reset Alarm" (see par. 12.5).
9.3.2 Unbalanced Load
This alarm is active when one of the three load current (read on the terminals T1, T2, T3)
differs from the others more than 30%.
The unbalanced alarm could be active also if there are a wrong wiring of the load.
When the problem is solved is necessary use the digital input: "Reset Alarm" (see par. 12.5).
9.3.3 Heater Break alarm (HB)
This alarm is active when the load current decrease under the threshold set on the parameter
P066 Ηβ_Σ (see par. 14.3).
The Heater Break alarm could be active also if there are a wrong wiring of the load.
When the problem is solved is necessary use the digital input: "Reset Alarm" (see par. 12.5).
The Heater Break alarm to work properly must have an input signal more then 25% of the
nominal current value.
Caution: In the first start, and each time that the load is replaced, it’s necessary
make the Calibration procedure.
9.4 Calibration Procedure
The Calibration procedure is an automatic procedure that save in memory the three different
values of load current (for each phase)
This procedure is necessary if you use the Burst Firing (BF) or if you use the Heater Break
Alarm.
To make the Calibration procedure follow these steps:
•
•
•
•
•
•
Give the power supply and start the thyristor unit (see par. 12.5).
Activate the digital input: "Cal" (terminal 19).
The HE3 thyristor unit give the maximum output voltage.
After a few seconds the values of voltage and current are stored in memory.
The HE3 thyristor unit returns to the initial situation.
Stop the thyristor unit.
The Calibration procedure is done.

11 Firing type
Choose an correct firing type allows to optimize the thyristor unit for the installed load.
The firing type has already configured in line with customer requirements that are defined in
the Order Code. The Order Code is written on the identification label.
However, if you wish to change the firing type you can use the software configurator or the
Control Panel (see par. 10).
Caution: this procedure must be performed only by qualified persons.
11.1 Single Cycle (SC)
Single Cycle it's the faster zero crossing switching method in relationship of the power demand
from a temperature regulator or from an external signal.
With input signal at 25% the output is one cycle ON and three cycles OFF
With input signal at 50% the output is one cycle ON and one cycle OFF
With input signal at 75% the output is three cycles ON and one cycle OFF
With input signal at 76% the output is the same of 75% but for each ON cycle the
microprocessor divides 76/75, and when the sum of rests is one, the unit does one more cycle
ON. For this firing is necessary to have analog input.
The Single Cycle is used to control the loads with low inertia or for infrared lamps to short

11.2 Burst Firing (BF)
The Burst Firing is similar to the Single Cycle, but consecutive cycles ON are selectable
between 2 and 255, with input signal equal at 50%.
Burst Firing is a method zero crossing that it reduces the electromagnetic interferences
because the thyristor switches at zero voltage crossing.

When the ramp is over, the thyristor unit will stay in conduction at full voltage up to the end
of cycles of burst. The S+BF firing is used to control small inductive loads to avoid inrush
surge current and to reduce the electromagnetic interferences.

11.3 Phase Angle (PA)
The Phase Angle firing allow the control of the power on the load, for this firing the thyristor
can be in conduction only for a part of the voltage cycle.
This part of the voltage cycle is adjustable in function of the input signal from 0 at 100%.
The PA firing is normally used for control the inductive loads, and is also possible control a
primary of transformer coupled with the cold resistances like: Superkanthal, Molybdenum,
Platinum, Tungsten or Quartz Lamp. The only disadvantage with phase angle is the possible
generation of interferences that however can be reduced with opportune filters.

11.4 Delay Triggering (DT)
The Delay Triggering firing is used the control a primary of transformer coupled with the
normal resistances on the secondary (N.B. don't connect cold resistances on the secondary
like: Superkanthal, Molybdenum, Platinum, Tungsten, Quartz Lamp).
For an inductive load (ex transformer), switching the thyristors at zero crossing can generates
transient over currents that can blow the fuses, to avoid this problem you must use the Delay
Triggering. This firing delay the first half cycle of Burst for an angle from 0 to 100° relative to
the zero, besides all the first burst start with soft start ramp to reduce the inrush current
during the cycle of magnetization.

Without delay at zero crossing when V1 is to zero (projected on the X axis) the unit switch On.
In this case the instantaneous value of the currents are i1, i2 and i3 and this condition, for the
curve of magnetization, could generate transient over currents that can blow the fuses.
With Delay Triggering the firing of the thyristor are triggered with a delay until the
instantaneous value of the curret i1=0, i2 positive and i3 negative like represented.
In this case the risk of transient over currents is reduced and the fuses don't blow.
The angle alpha is the delay to have i1=0 and this angle depends on the power factor.
The delay angle suggest for most applications is 80°

11.5 Action of the Limit Current
The Current Limit is available for each firing type.
It control the firing angle of the thyristor to maintain the three RMS current under the set value.
When the current exceeds this value, the voltage is decreased up to reach the current limit set.
I Load <= I Limit Set
I Load > I Limit Set
11.5.1 Current Limit Procedure
The current limit could be set through the analogic input 2: External Current Profiler, or in
digital mode through the parameter P091 ΧΛ .
To select Analog/Digital mode use the parameter P090 ΧΛ_ι
0 = Analog, Current Limit from analog input (terminals 9-7)
1 = Digital, Current Limit from parameter P091 ΧΛ
To make Current Limit Procedure follow these steps:
Caution: this procedure must be performed only by qualified persons.
•
•
•
•
•
Give the power supply and set the current limit to zero:
- In analog mode, set the analog input 2 at the min value (ex. 0V for 0÷10Vdc or 4 for
4÷20mA)
- In digital mode, set the parameter P091 ΧΛ =0
Start the thyristor unit (see par. 12.5).
Set the primary input or the setpoint value at 100% (see par. 12.3).

11.6 Feed-back type
The Feed-back type has already configured in line with customer requirements that are
defined in the Order Code. The Order Code is written on the identification label.
However, if you wish to change the Feed-back type you can use the software configurator or
the Control Panel (see par. 10).
Caution: this procedure must be performed only by qualified persons.
The Feed-back type is defined by the parameter P070 Φεεδ (see par. 14.3).
If the configurable digital input has set like Feed-Back Selection (see par. 12.5), it's possible
to change the select Feed-Back with the Voltage Feed-Back (V) simply activating the input.
The feed-back defines the Control Mode. It’s possible to have:
•
V=Voltage feed-back.
The input signal is proportional to the output voltage. This means that input signal
becomes a voltage demand. This control mode compensates the voltage fluctuation of the
incoming line supply.
•
I=Current feed-back.
The input signal is proportional to the current output. This means that input signal
becomes a current demand. This control mode maintain the current also if the load
impedance changes.
•
W=Power feed-back.
The input signal is proportional to the power output. This means that input signal
becomes a power demand. The power remains constant also if voltage and load
impedance change. This control mode is used with silicon carbide elements that change
its resistive value with temperature and with age. In addition it compensates the voltage
fluctuation of the incoming line supply.
•
EX=External feed-back 0÷10Vdc (see par. 12.3).
The input signal is proportional to an external signal. This means that input signal
becomes a demand to maintain this signal always constant. This control mode is used for
example with galvanic systems, where it's necessary to control the current value through
the electrodes.

The Baud rate can be 4800-9600-19200 Baud (Standard 19200).

Description
Read Holding Registers
Preset Multiple Registers
The unit support the Broadcast messages:
It' possible send a Broadcast messages using the address 0, all the units respond
at the message without sending back any reply.
13.2 Message Format
The transmission format is a 1 bit start, 8 date bit, and 1 bit stop with no parity verification.
Each message terminate after a said time of "time out", equal at 3.5 time of a character
transmission, where there are not transitions on the transmission line.
The first Byte of each message is always the address of the unit that is a value from 1 to 255
or 0 for the broadcast messages, the second is always the function number, and the rest of
the message depends of the function demand.
When a Slave receive an message, the unit send an answer with the same
structure but with the information demanded.
Each message is followed by CRC (Cyclic Redundancy Check) with two byte. The CRC identify
the incongruity situations of the message, in this case the receiver ignore the message.
The CRC is calculated in accordance with a formula that imply a recursive division of the data
by a polynomial.
The polynomial divisor is:
216 + 215 + 22 + 1(Hex 18005)
but is modified in two ways:
•
Since the bits order are reversed, then the binary pattern is also reversed, and the most
significant bit (MSB) is the right-most bit.
•
Since interest only the remainder, the right-most bit could be discarded.
Therefore, the polynomial divisor has value: Hex A001
Normal bit order:
Most significant bit
Least significant bit
Most significant Byte Least significant Byte
Reversed bit order:
Least significant bit
Most significant bit
Least significant Byte Most significant Byte
N.B.: With the reversed bit order, also the CRC16 returns the with the reversed bit order

16 Maintenance
16.1 Fans
The thyristor unit with forced ventilation uses fans that rotate permanently when the unit is
supplied. In case of fan failure, the heat-sink can be reach high temperature. In this case to
give protection to thyristor there is a thermal switch properly setted. The function of this
switch is to open the input signal until the heat-sink temperature falls below the setted value.
This means that also with input signal in ON condition the unit is switched OFF and the system
can not work at full power. For this reason is important to control periodically the fans status
checking that are rotating.
16.2 Maintenance
For maintain a correct cooling, the consumer must clean the heat-sink and the protective
grate of the fans. The frequency of these operations depends on the atmospheric local
pollution.
Check also that the screw of the power terminals and earth terminals are shut correctly
(see Diagram of control connection).
16.3 Repairing procedure
•
•
•
•
Phone to supplier.
Explain to Service Engineer the problem because sometimes it can be solved with a phone
call.
If this is not possible, ship the unit to supplier or to your distributor.
Write a fault description and give the name of your personnel to which refers.
Use a rugged packaging to ship the unit.
16.4 Warranty condition
