Safety Instructions
Obligation to give instructions
The following safety and operating instructions must be carefully read
before initial assembly, installation and commissioning of Thyro-A by
those persons working with or on Thyro-A.
These operating instructions are part of the Thyristor switch Thyro-S.
The operator of this device is obliged to provide, without restriction,
these operating instructions to all persons transporting, commissio-
ning, maintaining or performing other work on this device.
In accordance with the Product Liability Act, the manufacturer of a
product has an obligation to provide explanations and warnings as
follows:
• the use of the product other than for the intended use,
• the residual product risk as well as
• operating errors and their consequences.
The information given below must be understood in this respect. It is
to warn the product user and protect him and his systems.
Proper use
•The Thyristor switch is a component which may only be used for
control and regulation of electrical energy.
•The Thyristor switch may at most be operated using the maximum
admissible connected load according to information on the type
plate.
•The Thyristor switch may only be operated in connection with a sui-
table and series connected power supply disconnecting device.
•As a component, the Thyristor switch is unable to operate alone and
must be projected for its intended use to minimize residual risks.
• The Thyristor switch may only be operated in the sense of its inten-
ded use, otherwise hazards to persons (e.g. electric shocks, burns)
and systems (e.g. overload) may arise.

48
49
EN
Residual hazards of the product
• Even in case of proper use, should a fault occur, it is possible that
control of currents, voltages and power is no longer performed in the
load circuit by the Thyristor switch.
In case of destruction of the power components (e.g break-down or
high resistance), the following situations are possible: power interrup-
tion, half-wave operation, continuous power flow. If such a situation
occurs, then load voltages and currents are produced from the phy-
sical dimensions of the overall power circuit. It must be ensured by
system design that no uncontrolled large currents, voltages or power
occur.
Maloperation and its results
• With maloperation it is possible that power, voltage or flow levels
which are higher than planned reach the Thyristor switch or load.
On principle, this can lead to the Thyristor switch or load being da-
magad.
Transport
• Thyristor switches are only to be transported in their original
packaging (protection against damage e.g. due to jolting, knocking,
soiling).
Installation
• If the Thyristor switch is brought into the operation room from a cold
environment, moisture can occur. Prior to it being commissioned,
the Thyristor switch must be absolutely dry. Therefore, wait for a
minimum of two hours before commissioning.
Connection
• Prior to connection, it must be ensured that the voltage information
on the type plate corresponds with the mains voltage.
• The electrical connection is carried out at the designated points with
the required cross section and the appropriate screw cross sec-
tions.
Operation
• The Thyristor switch may only be connected to the mains voltage if it
has been ensured that any hazard to people and system, especially
in the load section, has been eliminated.
• Protect the device from dust and moisture
• Do not block vents.
Maintenance, service, malfunctions
CAUTION
For maintenance and repair work the Thyristor switch
must be disconnected from all external voltage sources
and protected against restarting. Make sure to wait mini-
mum 1 minute after switch-off (discharge time of the at-
tenuation capacitors). The voltage-free state is to be de-
termined by means of suitable measuring instruments.
This work is only to be carried out by a skilled electrician.
The electrical regulations which are locally valid are to
be adhered to.
CAUTION
The Thyristor switch contains dangerous voltages. Repairs
may only be carried out by qualified and trained mainte-
nance personnel.
CAUTION
Danger of electric shock. Even after disconnection from
the mains voltage, capacitators may still contain a dan-
gerously high power level.
CAUTION
Danger of electric shocks. Even when the Thyristor switch
is not triggered, the load circuit is not disconnected from
the mains.
ATTENTION
Different components in the power section are scre-
wed into place using exact torques. For safety reasons,
power component repairs must be performed by AEG
Power Solutions GmbH.

1.1 General
Thyro-S is a Thyristor switch with the ability to communicate. It will
also be referred to as Power Controller or simply controller. It can be
used wherever voltages or currents need to be controlled in proces-
sing technology. With its good coupling ability to process and automa-
tion technology, high control precision and simple handling, Thyro-S
is also future-orientated for new applications. The Thyro-S is suitable
for a direct supply of ohmic loads.

2. Functions
2.1 Operating modes
Full wave switch
Depending on the digital set point signal the mains voltage is swit-
ched. In the operating mode 1:1 almost no harmonics are created in
the mains frequency. Whole multiples of the mains periods are always
switched.
For commissioning etc, a reduced supply can be switched with the
S1 switch or via the optional bus module, the control system thereby
either forces the switching of every 2. wave or an equal number of
positive and negative half waves.
In all operation modes d.c. components are avoided:
Operating mode Load voltage
1:1 every mains full wave
(nom. oper. mode, default setting)
1:2 every 2. mains full wave (DC-free)
1:3 every 3. mains full wave (DC-free)
1:5 every 5. mains full wave (DC-free)
2.1.1 Digital set point inputs
The Thyristor switch Thyro-S is equipped with two set point inputs
which are electrically isolated from the mains for triggering signals:
• Set point input 11 logic input 0-24V DC (Ri > 3,3 k h ) IN: UIN > 3V
• Set point input 2 via bus module
2.1.2 Switching behaviour
The Thyro-S can switch single or continuous full waves in the mains
voltage to the load. If a voltage of >3V is fed into X22.1 the following
mains period is switched.
If a full wave is to be switched to the load, the trigger signal ON must
be switched on not later than 1 ms before the mains voltage cross-
over otherwise it remains inactive. No new full wave is triggered if the
trigger signal is interrupted up to 1.25 ms before the crossover of the
full wave.
With a pulse trigger the pulse duration must be min. 1 ms.
2.2 Indications
The LEDs on the front signal the following states:
• ON GREEN operating indication,
power supply controller device
Blinking indications are described in table 2.
2.3 Monitoring
2.3.1 Monitoring of the mains voltage
The limiting values of the voltage are -57% for undervoltage monito-
ring and +10% for overvoltage monitoring. This produces the follo-
wing absolute limiting values:
Type Undervoltage Overvoltage
230V 99V 253V
400V 172V 440V
500V 215V 550V
NOTE
The devices may only be operated up to the undervol-
tage limit if he electronics are supplied by an ext. 24V
voltage. If the undervoltage limit is undercut the pulse
lock is activated and realy K! is released (default).

2.3.2 Equipment temperature monitoring
The control board is equipped with a temperature monitor.
If a fault occurs, the red LED blinks.
2.3.3 Ventilator monitoring
The separately ventilated power controllers (F) are fitted with thermal
monitoring. The temperature of the heat sink is measured. In case of
a temperature overrange a fault indication (red LED) ensues.
2.4 Additional indications using type S...H RL1
The LEDs on the front indicate the following situations:
• Diagnosis GREEN additonal error diagnosis
• LOAD FAULT RED error present
Flashing LED indications are described in table 2. Whether the semi-
conductor fuse is responding can be indicated by the error indication
relay K1 (undercurrent detection).
2.4.1 Error indication relay K1
The K1 relay has a changer and deenergizes if an error is detected in
the system (chapter 3.2). The table shows the pin connections on the
terminal strip concerned.
Root N/O contact N/C contact
Error indication relay K1 X3.1 X3.2 X3.3
2.5 Additional indications using type S...H RL1
Thyro-S ... H RL1 indicates errors occurring in the controller or load
circuit.
Indications are given via LED (LOAD FAULT) and via the K1 relay.
The device continues to run during errors as standard (can be confi-
gured using the Thyro-Tool Family).
2.5.1 Thyristor short-circuit monitoring
The devices of the Thyro-S...H RL1 series have built in thyristor short-
circuit monitoring. If no set point signal is available at the device, the
thyristor short-circuit monitoring checks the current flow to the load.
If a current >10% of the controller current is measured, the indication
„thyristor short-circuit“ is given. In the case of an error the relay dee-
nergizes, the Test-LED as well as the Load Fault LED flash intermit-
tently and Bit 14 appears in the status word.
The relay function can be configured with the Thyro-Tool Family soft-
ware.
The indication is only given if the error has been detected 3x and the
break time is >2 mains periods.
2.5.2 Load monitoring (undercurrent monitoring)
Thyro-S ... H RL1 is suitable for monitoring loads resulting from one or
several resistances in parallel or parallel series connection.
Thyro-S detects an increase in the load resistance. The load monito-
ring operates as undercurrent monitoring on absolute values and is
suitable for use in the nominal operating mode 1:1, and with limita-
tions in the operating modes 1:2. 1:3 and 1:5.
The load monitoring is supplied with the default configuration OFF =
left stop R205 (=0)
For all other configurations:
If the load current falls below the level set the error indication relay will
respond with a delay (4-10 sec depending on operating mode). The
result is indicated via an optionally connected bus system.
This can be set in accordance with the following table.
2.5.3 Load monitoring (overcurrent monitoring)
Along with undercurrent monitoring 2.5.2 the device also has over-
current monitoring. This can only be configured using Thyro-Tool
Family.

Deviating values are to be converted by percentage. The set monito-
ring value should always be “midpoint” between the value with load
current and the value after interruption.
NOTE
Settings above 90% and below 10% are not practical. If
low load currents are required, check whether a control-
ler with a lower type current can be used.
3. Operation
3.1 Configuration switch S1
A 4-pole DIP switch is situated at the front behind the hood. The indivi-
dual switches are marked from 1-4 starting from the bottom and must
be set before operation. They are only read in once when switched on
(mains recovery). For safety reasons further operation is carried out
with the hood closed.
S1- 1 2 Operating mode

1 0 1:2 operation
0 1 1:3 operation
1 1 1:5 operation
For operations where initially no nominal load is possible (e.g.drying)
reduced power can be controlled by Thyro-S independently.
With 1:2 operation each 2. cycle is switched, with 1:3 and 1:5 ope-
ration half cycles are switched with alternating polarity so that while
switched on the load is supplied with d.c.-free energy.

4. External connections
To connect the control signals use twisted or screened control lines. If
the controller is being used in UL conditions then only 60°C or 75°C
copper wires are to be used for the power connections in accordance
with the instructions in the technical data.
4.1 Power supply for Thyro-S
The connection of the power supply is to be made in accordance with
the connection diagrams and TECHNICAL DATA.
4.2 Power supply for control electronics
The control electronics are usually supplied directly from the power
connections. Connections U1 and X1.1 are needed for this.
This voltage (mains voltage) is used simultaneously for mains syn-
chronisation. With device types H RL 1 a 24V supply can be con-
nected additionally (AC or DC). This is advantageous if, for example,
you are using a bus system. With device types H 1 the mains voltage
must be in the range of -57% to +10% from the type value; with de-
vice types H RL 1 in the range of -15% to +10%. If the mains voltage
here is smaller than -15% then with these types the additional 24V
supply is needed. The permitted frequency range of the mains vol-
tage is between 47Hz and 63Hz. If the Thyro-S is operated between
two phases, so if a phase is available at X1.1, then an additional fuse
must be installed (see attached connection diagram on page79/81).
The connections X1.1 and X1.2 are bridged internally
4.3 Additional control voltage input
The thyristor switch Thyro-S 1S H RL1 is equipped with an additional
24V AC/DC power supply input. [X1: 1.2 1.5 mm2, grid 3.5]. If needed,
e.g. when operating with a bus, or voltages below the tolerance (e.g.
with undervoltage of a 440V mains with a 500V Thyro-S) the control
device can be supplied additionally with 24V AC or DC. The 24V vol-
tage must be unearthed (SELV) and must not be connected to the
control earth. However, several Thyro-S switches can be operated on
a 24V supply. The input is reverse polarity protected. The connection
output for the control device is circa 2W (5VA) per actuator.
The 24V connection lines are to be fused in accordance with the ap-
plicable regulations. A soldered in fuse protects the device in case of
internal short-circuits.
4.4 Digital set point input
The digital set point input X22.1 works with a logic signal. It can, for
example, be gated by 24V DC. If a voltage of more than 3V is availa-
ble at this input then the Thyro-S is switched on; below 3V it is swit-
ched off. Between terminals X22.1 (input) and X22.2 (+15V) a switch
or relay contact, for example, can be operated. If a voltage is applied
directly to X22.1 (+) then its reference point must be connected to
X22.3 (earth).
All control terminals are connectable with up to 1.5 mm2and have a
3.5mm grid.

5. Interfaces
The Thyristor Switch of type range Thyro-S...1 are all equipped with
a system interface at terminal strip X22. Either a bus module or a PC
interface with a PC connection can be operated from this.
5.1 Bus module at the system interface
The optional bus module enables the Thyro-S range Power Controller
to be connected to a field bus. The bus module is hereby connected
to the Power Controller’s system interface (terminal strip X22) with
prefabricated cables on the bus module side. Up to eight Thyro-S (or
also combined with Thyro-A) can be connected to the bus system
with one bus module, e.g. Profibus-DP, Modbus RTU, CANopen or
DeviceNet.
The bus module connection configuration is identical for all available
bus modules. Further information can be obtained from the operating
instructions of the respective bus module.
REMARK
Further useful functions for the application are possible
via field bus by the access of set point value, actual va-
lues, parameters as well as fault diagnosis.
5.2 PC-Interface RS232 at the system interface
The Power Controller is connected to a PC via the serial interface
(COM1, COM2 ...) with the PC-INTERFACE RS232. In addition, an
RS232-DATALINE, Order No. 0048764 is needed (not crossed, the
connection 2, 3, 4, 5 and 7 are used).
The PC-INTERFACE RS232 must be connected to the terminal strip
X22 according to the instructions included.

5.2.1 Thyro-Tool Family
Fig. 7 User surface Thyro-Tool Family
Thyristor Switch of the Thyro-S range can be operated and set ef-
fortlessly with the aid of the PC software THYRO-TOOL FAMILY.
Necessary for working with Thyro-Tool Family is that the connection
between PC and Power Controller is present (see 5.2). This makes
visual readings, parameter viewing and fault diagnosis possible. If
Thyro-S is not operated in Thyro-Tool mode, certain parameters can
be changed. In Thyro-Tool mode changes to almost all parameters
are possible.
To change over the set point a switch can be connected to the PC-
INTERFACE RS232 and X1.3. If these terminals are connected, the
digital set point of THYRO-TOOL FAMILY is active. With open termi-
nals the analogue set point at X2.4 is used.
6. Mains load optimization
Thyro-S is not suitable for mains load optimization in multiple con-
troller applications. If mains load optimization is necessary, Thyristor
controllers of type Thyro-A or Thyro-P must be used.
7. Connecting diagrams
Thyro-S can be employed in single phase switch and in three phase
switches which can be transposed to single phase switches, e.g. star
connections with MP conductor or N conductor and in open delta con-
nection.
It is possible to apply 2 identical Thyro-S as a three phase saver cir-
cuit (with delta load or star without N), if the triggering signal for both
controllers is set up at the same time. See 11, page 81

8. Special remarks
8.1 Installation
Thyro-S requires a vertical fitting position. With cabinet mounting suf-
ficient ventilation of the cabinet must be ensured. The distance bet-
ween the Power Controller and the cabinet ceiling or other mountings
should be at least 150 mm. The distance below the Power Controller
should be at least 100 mm. The devices may be installed next to each
other without lateral distance. Heating up of the device by heat sour-
ces must be avoided. The dissipation of the Power Controller is stated
in the Type overview table.
ATTENTION
Grounding must be carried out according to local elec-
tricity board regulations! (grounding screw for protective
conductor connection on fastening adapter is provided).
The grounding also serves EMV devices (Y capacitor
4.7 nF).
For Thyro-S with type currents up to 60A, adapters can be delivered
for the 35 mm top-hat rail assembly.
8.2 Commissioning
The device must be connected to the mains and the associated load
according to the corresponding connecting plans.
On delivery the device is parameterized and adjusted to the respec-
tive power section. If a different operating mode is desired, then it
must be set with DIP fix 1 and 2 by the user (commissioning phase).
ATTENTION
Heat sinks and neighbouring plastic parts can become hot
during operation
8.3 Service
The devices delivered have been produced under quality standard
ISO 9001.
Should nevertheless faults or problems occur, our 24-hour service
hotline: Phone 02902 / 763-100 is at your service.
8.4 Checklist
• LED ON lights up green -> mains voltage or supply voltage is
available
• LED ON not lights up green
· Check fusing of the power unit (built in semi-conductor fuse F1).
If the fuse is defective check load and wiring to load.
· Check synchronisation voltage on X1.1
· Check external back-up fuse
· Check control fuse (F2) 500V 1.6A
· With Thyro-S ...H RL 1 check 24V (AC/DC) power supply where
applicable
• Supply available but no load current
· Check mains voltage
· Switching on signal (digital set point, X22.1 versus X22.3 ≥ 3)
· Check load circuit for interruptions
· Check flashing LED signals (chapter 3.3)
• Load current does not have the expected value
· Check switching on signal (digital set point) for continuous signal
ON.
With optional bus module:
· Check bus switching on signal (bus set point) for continuous signal
ON.
. Check all parallel load resistances for current flow.
• Load current is flowing without triggering
· Check the wiring of the power unit (in case of first activating).
In very rare cases a thyristor short circuit may have occurred.
