The safety instructions and operating manual are to be carefully
read prior to installation and commissioning
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 Power Controller Thyro-A.
The operator of this device is obliged to provide, without restriction, these operating
instructions to all persons transporting, commissioning, 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,
• operating error and its 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 Power Controller is a component which may only be used for control and regulation of electrical energy.
• The Thyristor Power Controller may at most be operated using the maximum
admissible connected load according to information on the type plate.
• The Thyristor Power Controller may only be operated in connection with a
suitable and series connected power supply disconnecting device (e.g. switch,
VDE 0150 T1).
• As a component, the Thyristor Power Controller is unable to operate alone and
must be projected for its intended use to minimize residual risks.
2
The Thyristor Power Controller may only be operated in the sense of its intended
use; otherwise personal hazards, for (e.g. electric shocks, burns) and hazards for
systems (e.g. system overload) may arise.
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 Power Controller.
In case of destruction of the power components (e.g. break-down or high resistance), the following situations are possible: power interruption, half-wave operation, continuous power flow. If such a situation occurs, then load voltages and currents are produced from the physical dimensions of the overall power circuit. It must
be ensured by system design that no uncontrolled large currents, voltages or power
occur.
Maloperation and the results
• With maloperation it is possible that power, voltage or flow levels which are
higher than planned reach the Thyristor Power Controller or load. On principle,
this can lead to the Power Controller or load being damaged.
Transport
• Thyristor Power Controllers are only to be transported in their original packaging
(protection against damage e.g. due to jolting, knocking, soiling).
Installation
• If the Thyristor Power Controller is brought into the operation room from a cold
environment, moisture can occur. Prior to it being commissioned, the Thyristor
Power Controller 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 sections.
3
Operation
• The Thyristor Power Controller 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 Power Controller must be
disconnected from all external voltage sources and protected against
restarting. The voltage-free state is to be determined 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 Power Controller contains dangerous voltages. Repairs
may only be carried out by qualified and trained maintenance personnel.
CAUTION
Danger of electric shocks. Even after disconnection from the mains
voltage, capacitators may still contain a dangerously high power
level.
CAUTION
Danger of electric shocks. Even when the Thyristor Power Controller is
not triggered, the load circuit is not disconnected from the mains.
ATTENTION
Different components in the power section are screwed into place
using exact torques. For safety reasons, power component repairs
must be performed by AEG SVS Power Supply Systems GmbH.

1. Introduction
Thyro-A has been conceived to meet the demands for simple assembly, speedier
commissioning and safer operation.
For transport, assembly, installation, commissioning, operation and decommissioning, it is essential that the safety instructions included in these operating instructions
are observed and made available to all persons handling this product.
In case of uncertainties or missing information, please contact your supplier.
The described operating mode QTM is being prepared.
1.1 General
Thyro-A is a Thyristor Power Controller with the ability to communicate. It will also
simply be referred to as Power Controller or Controller. It can be used wherever
voltages or currents need to be controlled or regulated in processing technology.
Thyro-A’s distinguishing features are its several operating and control modes, good
coupling ability to process and automation technology, high control precision and
simple handling through a 16-Bit processor.
1.2 Specific characteristics

➜ easy handling
➜ type range 230-500 Volts, 8-280 A, single and double phase
➜ ohmic load and transformer load
➜ soft start function for transformer load
➜ control modes U, U2
➜ operating modes TAKT, as well as VAR and QTM with Thyro-A 1A
➜ control with analog set points and / or via optional bus adapter

➜
2. Functions
To enable Thyro-A to adjust optimally to the desired application, it is equipped with
a wide range of functions. These are described below. Further functions are possible
by applying Thyro-A within a bus system. See also chapter 5 INTERFACES.
2.1 Operating modes
For adjustment to different electrical loads, the most favourable operating mode can
be chosen.
Full wave switch TAKT (for 1A, 2A)
Depending on the prescribed set point, the mains voltage is periodically switched. In
this operating mode almost no harmonics are created. Whole multiples of the mains
periods are switched, thus avoiding d.c. components. The full wave switch mode is
especially suited for loads with thermal inertia. Depending on the function angle
1. half wave, the phase frequency is adjusted independently to 5 or 50 mains
periods = To.
The phase operation creates minimal mains reactions. Should there be a flicker, this
can be minimized with the aid of the mains load optimization.
14
Phase-angle principle VAR (for 1A))
Depending on the prescribed set point, the sine oscillation of the mains voltage is
gated using a larger or smaller control angle . This operating mode is characterized by high control dynamics.
With phase-angle control harmonics of the mains voltage occur. It is possible to
compensate these by using circuit variants.
Half-wave switch mode QTM (Quick-Takt-Mode for 1A)
QTM is the patented fast operating mode which works on the half wave switch principle. Depending on the prescribed set point, mains half waves are switched. D.c.
components are avoided for the phase duration. The fast phase control is particularly suited for IR beams as an alternative to phase-angle control. When using several
controllers it is possible, by synchronisation, to keep the mains reactions small.
2.2 Set point control characteristic
The set point control characteristic of Thyro-A can easily be adapted to the control
output signal of an upstream process controller or automation system. All signals customary on the market may be used. The adaption is made by changing the starting
and ending points of the control characteristic.
If the controller is within a limit (Umax), both red LEDs blink alternatively in second
intervals (chapt. 3.3).
Fig. 1 Control characteristic analog input
15
Input set points
The Power Controller Thyro-A is equipped with two input set points which are isolated from the mains.
• Set point 1
• Set point 2
analog (X2.4 – X2.3 ground)
system interface
The analog input can be adapted to the various process controllers by means of
the set point and live zero set point switches. The following signal ranges can be
set:
0(4)-20mA (Ri = ca. 250), 0-5V (Ri = ca. 44k), 0-10V (Ri = ca. 88k).
Within the stated input ranges these values with the control characteristic may be
adjusted to any common signal characteristic.
+5V supply voltage can be taken for a set point potentiometer from terminal X2.8
(5k RPoti 10k).
The effective set point is the total set point. It is made by adding the two set points. It
is either the analog set point or the bus set point. If the bus module is connected and
in operation, the bus set point is effective.
If the bus module or bus (e.g. Profibus-DP) is interrupted, the controller automatically
switches to the analog set point.
Fig. 2 Set point inputs and total set point
16
2.3 Control types
Thyro-A …H 1 has two control types. Mains voltage variations and load changes
are directly and quickly adjusted by bypassing the sluggish temperature control
system.
Before commissioning the Power Controller and selecting a control mode, familiarisation with the operating procedure and the effect upon the application is important.
2.3.1 Controlled value
The controlled value effective on the load is proportionate to the total set point,
depending on the control type.

2.5 Monitoring
Faults occurring in the Power Controller are signalled. Signalling ensues via red
LED.
2.5.1 Monitoring of the load and mains voltage
The limiting values of the voltage are -57% of the type voltage for undervoltage
monitoring and +10% of the type voltage for overvoltage monitoring. This produces
the following absolute limiting values:

3. Operation
This chapter describes the operating elements of Thyro-A. For default settings see
chapter 8.2.
3.1 Configuration switch S1
A 8-pole DIP switch is situated at the front behind the hood. The individual switches
are marked from 1–8 starting from the bottom and must be set before operation
18
according to application. They are only read in by the Power Controller once when
switched on or with mains recovery. For safety reasons further operation is carried
out with the hood closed. (3.2).

3.2 Potentiometer R201
3.2.1 Phase angle 1. half wave (TAKT operation)
Potentiometer R201 serves to set the transformer load. At works it is set at
60° el with Thyro-A 1A and at 90° el with Thyro-A 2A.
Transformer loads with a nominal induction > 1.2 T, as well as wound core and toroidal core transformers optimization is necessary. With Thyro-A 1A generally 80°el turn
(to the right), with Thyro-A 2A turn at smaller angles (to the left). An optimal setting is
achieved when the rush current is minimal.

With a solely ohmic resistance load the poti can be turned to the left limit stop, at
30°el Thyro-A independently switches to a faster pulse operation with To = 5 periods without SST. In this configuration the terminal X2.7 can be used as an additional
digital “set point value” (24V d.c.). This also permits the controller to be driven by a
2-point controller.
3.3 Diagnosis / status indications
Faults can occur in the load circuit and in the controller itself or from the mains.
Diagnosis of unexpected operating behaviour is performed by LEDs on the front
panel of the control device.

4. External connections
4.1 Power supply for Thyro-A
Connecting the power supply is carried out as shown in the figures and TECHNICAL
DATA. With Thyro-A 2A a right rotational field in the power circuit is required.
20
4.2 Power supply for the control device
The control device is supplied directly from the power section (terminals U1,
X1:1.2). This voltage also serves as mains synchronization. The mains connection is
equipped for input voltages of Unom – 15% to +10% and nominal frequencies of
47Hz to 63Hz. Both terminals (X1:1.2 1.5mm2 grid 3.81) are internally bridged. If
a phase is connected to X1, a fused connection is necessary (figs. 3,7).
4.3 Pulse lock
The pulse lock (PULSE INHIBIT; terminals X2.1 - X2.2 1.5mm2, grid 3.5) is activated
by opening the pulse-lock bridge, i.e. the power section is no longer triggered. If the
pulse lock is activated the LED “PULSE INHIBIT” lights up red. It is imperative to use
the pulse lock with transformer load in order to activate the Soft Start function. It may
only then be released when there is a voltage supply to the power section. With
Thyro-A 2A the pulse lock is only wired to the master (L1, left).
4.4 Analog set point value input
The set point value input (terminal X2: 3 ground - X2:4 + 1.5mm2 grid 3.5) is
suitable for process controllers with output signals of 0(4) - 20mA, 0-5V, 0-10V.
4.5 Digital set point value input
Under certain conditions terminal X2.7 can be used as additional digital “set point
value input” (24V d.c.) so that, for instance, Thyro-A can be triggered by a 2-point
regulator. Further information is available on this in chapter 3.2.1.
4.6 Voltage transformer
The load voltage is recorded by the measuring signal given by the supply voltage. This
value is linked with the control angle or the pulse ratio Urms = Umains * √ (TS/To). The
voltage transformer only has local mode wiring.

With its system interface terminal strip X22 the Power Controller Thyro-A can be
connected via an optional bus module to, for example, Profibus DP or Modbus RTU
(other bus modules available on request). Description and connections can be taken
from the instructions of the respective components.
REMARK
The access to set value, actual values and parameters made possible
through bus provides further useful functions for application, e.g. software synchronization. The corresponding operating instructions provide further information on this.

6. Mains load optimization
Thyro-A can be operated in multiple controller applications with mains load optimization. The application of mains load optimization offers substantial advantages,
e.g. reduction of mains load peaks and mains reactions.
Mains load optimization is possible in multiple controller applications in which either
the operating mode TAKT (slow pulse at AN_1 30°el) or operating mode QTM is
applied.
24
6.1 Synchronization SYT-9 (operating mode TAKT)
SYT-9 is a process for static load optimization. It minimizes main load peaks and
associated mains reaction shares. Set points and load changes are not automatically
included in mains load optimization.
The SYT-9 process requires and additional component. It can also be employed in
connection with AEG controllers already installed. Then the pulse must be connected
to terminal X2.7 and the +5V for the SYT-9 card must be connected to X2.8.
The operating mode TAKT contains a high pulse frequency (AN1 30°el for ohmic
load, To = 5 supply periods) as well as a low pulse frequency (To = 50 supply
periods). The low pulse frequency is also suitable for switching transformers and is
activated independently at phase angle 30°el.
Only in this operating mode is the input X2:7 scanned. Is a pulse recognised, impulse is switched on and the pulse time To applies from here.
The impulse is switched by the Synchrotakt component via an optoelectronic coupler.
Energy comes from its own controller (X2.8).
Please observe the operating instructions of the SYT-9 component.
6.2 Synchronization in operating mode QTM (1A)
In the operating mode QTM the synchronization of 2-12 controllers is possible.
The operating mode QTM works in rapid half-wave frequency with a pattern of switched and locked half waves at particular intervals 1 sec, also designated as To.
To achieve a balance in supply from the outset (not after To) the individual controllers
synchronize themselves by staggering by one supply period. With the first connected controller the SYT input X2.7 is jumped to +5V X2.8.
The following controllers receive their impulses at X2.7 from sync. output X2.6 of the
previous controller. With the last controller X2.6 remains free (series connection).
This synchronization method is only possible with Thyro-A 1A (see Fig. 9).
.
6.3 Software synchronization (operating mode TAKT)
The application of an optional bus module activates the software synchronization.

8. Special remarks
8.1 Installation
Thyro-A requires a vertical fitting position. With cabinet mounting sufficient ventilation of the cabinet must be ensured. The distance between the Power Controller and
the cabinet ceiling or other mountings should be at least 150mm. The distance below the Power Controller should be at least 100mm. Heating up of the device by
heat sources 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 regulations!
(grounding screw for protective conductor connection on fastening
adapter).
The grounding also serves EMV devices (Y capacitor 4.7 nF).
For single-phase devices with type currents 8A, 16A or 30A an adapter can be
delivered for the 35mm 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 respective power section. The operating mode TAKT (S1-1, S1-2) for transformer load (R201) is set. If a
different operating mode is desired, then it must be set by the user. The following table shows the default settings of the DIP switch.

All standard settings should be checked by the user as a matter of course and adjusted to the operating conditions (e.g. operating mode, control mode, limits, monitoring, control characteristics, actual value output, fault indications etc.)
REMARK
Apart from the load and current supply to X1.1, certain control signals
must be connected too. The following signals are essential for operating the device:
Set point
Pulse lock
(terminal 4 or by system interface)
(on ground, on terminal 1,2; jumper)
If the pulse lock jumper is not connected, the device is in a locked state and will not
operate. Communication via interface is still possible. Further details on the pulse
lock are described in the chapter of the same name.
ATTENTION
Heat sinks and neighbouring plastic parts are hot during operation
( 70°C)! Provided sign should be fixed nearby Thyro-A.
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: Tel: 02902 / 763-100.
is at your service.

8.4 Checklist
• LED ON green does not light up
- Check fuse control 500V 1.6 A, if defective check external wiring, also applies
to faults of external fusing.
- Check Power Controller fusing. If fuse is defect then check load and wiring to
load. Synchronization voltage is supplied to X1.1.
- With transformer load, check phase angle 1 (TRAFO ADAPTION) - fuse release
caused by rush current is possible if setting is incorrect.
- Check 5 Volt to X2.8. If this voltage is absent or too low, there is a defective
component.
• Supply available but no load current
- Check that pulse lock is cleared (jumpered) terminal X2.1,2
- Check set point
- Check for load interruption
- Check blinking LED indications (chapt. 3.3)
• Load current does not have expected value
- Check set point
Terminal X2.4 against X2.3 ground or
Bus set point (with optional bus module)
- Set point/controller value, max. value correctly parameterized
- Check all parallel load resistances for current conduction
- Check control end for correct setting
- Check control characteristic adjustment (U, live zero)
• Load current flows uncontrolled
- In rare cases a Thyristor short-circuit can occur.

Set point inputs
The Power Controller Thyro-A has 2 set point inputs. The set point inputs are safely
disconnected from the mains (SELV, PELV).
Set point 1: External set point input signal ranges:
0(4)-20 mA Ri = ca. 250 0-5 V
Ri = ca. 44 k
0-10 V
Ri = ca. 88 k
Set point 2: System interface, connection from superset PC or automation

Control characteristic
The control characteristic is established by the maximum value of the dimensions to
be controlled and the key values of the set point. Using these key values, the linear
control characteristic may be set as desired.
Each controller (e.g. temperature controller) whose output signal lies within the
range 0-20mA / 0-5 V / 0-10 V, can easily be adapted to the Power Controller.

The following approvals and conformities are available for Thyro-A
• Quality standard according to DIN EN ISO 9001
• UL registration, file no. E 135074, under preparation, with consideration to
Canadian National Standard, project no. 02ME08043
• CE conformity
• Low voltage directive 73/23 EEC
• EMV directive 89/336 EEC; 92/31 EEC
• Marking directive 93/68 EEC
There is no product norm for Thyristor Power Controllers so that a sensible norm
structure must be set up which ensures safe application and opportunity for comparison.
CAUTION
Thyristor Power Controllers are not devices for disconnection in the
sense of DIN VDE 0105 T1 and may therefore be operated only in
connection with a suitable mains isolating device (e.g. switch, isolating
link).
Further norms are adhered to, e.g. voltage dips according to 61000-4-11:8.94 are
ignored by the control device or registered by triggering off monitoring. Generally
an automatic start is made after the mains returns within the tolerances.
