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 advise 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.
56
The Thyristor Power Controller may only be operated in the sense of its intended
use; otherwise personal hazards, (e.g. electric shocks, burns) and hazards for
systems (e.g. system overload) may arise.
Residual hazards of the product
• Even in 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
power circuit. It must be ensured by system design that no uncontrolled large
currents, voltages or power occur.
Malfunction and the results
With malfunction it is possible that power, voltage or flow levels which are higher
than planned reach the Thyristor Power Controller or load. In 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 due to condensation 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 cable and the appropriate screw cross sections.
57
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, capacitors 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.

➜
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 optimum adjustment to different applications and production processes, as well
as different electrical loads, the most favourable operating mode can be set.
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 = T0.
67
The TAKT operating mode creates minimal mains reactions. Should there be a
flicker, this can be minimized with the aid of the mains load optimization.
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.

68
If the controller is within a limit (Umax, Imax, Pmax), both LED PULSE INHIBIT and LOAD
FAULT blink alternatively in second intervals (chapt. 3.3).
Input set points
The Power Controller Thyro-A is equipped with two input set points which are
isolated from the mains, of which only one is always active.
• Set point 1 analog (X2.4 – X2.3 ground)
• Set point 2 via bus module
The analog input can be adapted to the various process controllers by means of
the set point and live zero switches as well as the potentiometer controlling set point
input. The following signal ranges can be set:
0(4)-20 mA (Ri = ca. 250 ), 0-5 V (Ri = ca. 44 k), 0-10 V (Ri = ca. 88 k).
+5V supply voltage can be taken for a set point potentiometer from terminal X2.8.
(5 k RPoti 10 k)
The effective set point is the patched through set point. Within the stated input
ranges these values with the control characteristic may be adjusted to any common
signal characteristic.
Fig. 2 Set point inputs and total set point
2.3 Control types
Thyro-A has four control types Thyro-A...H RLP with additional P-control). 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:

2.3.2 Limitations
Independent of the voltage output control, limiting current values can additionally be
set (chapt. 3.2.3).
2.3.3 Controller response

Blinking indications are described in chapter 3.3.
Activation of the integrated semiconductor fuse can be signalled using the K1 fault
indicating relay (undercurrent detection).

2.4.2 Alarm relay K1
The relay K1 is deactivated if a fault is detected in the system (Chapt. 3.3).
This has a relay. The following table shows the configuration of the corresponding
terminals.
Alarm relay K1
Root
X3.1
Closer
X3.2
Opener
X3.3
2.5 Monitoring
Faults occurring in the Power Controller and the load circuit are signalled. Signalling
ensues via LED (LOAD FAULT) and via the K1 relay.
2.5.1 Monitoring of 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:
Type
230V
400V
500V
Undervoltage
99V
172V
215V
Overvoltage
253V
440V
550V
NOTE
When operating below the type voltage (-15%), the devices may only be
operated down to the undervoltage limit if the electronics are supplied
by an ext. 24V voltage. If the undervoltage limit is undercut, the pulse
lock is activated internally and relay K1 is released.
2.5.2 Absolute value monitoring current
This function allows monitoring of a freely selectable absolute current limit. The
value is set by potentiometer R205. During the setting procedure an instrument
connected to the analog output indicates the monitoring value. (Chapt 3.2) This
absolute value monitoring lends itself to one or more load resistances arranged in
parallel. Generally, the effective current value measured is continuously compared
with a presettable absolute current limit for undercurrent. If this limit is undercut, an
indication shows. In the case of resistance elements arranged in parallel, it is possible to select a partial load interruption by setting the undercurrent limit accordingly.
(Chapt 3.2.5).
2.5.3 Equipment temperature monitoring
The control board is equipped with a temperature monitor.
71
If a fault occurs the LED LOAD FAULT blinks and the alarm relay K1 is released.
2.5.4 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 ensues and relay K1 switches default settings.
2.6 Set point processing when employing a bus module
The set point processing depends on how the bus module is connected to the Power
Controller. Different variations can be realized depending on the requirements. The
circuit of Thyro-A’s terminal X22.1 controls the procedures (Chap. 2.2, fig. 2).
• No connection to X22.1
The bus module is fully functional, the set point value is, however, only accepted at
the controller via the control terminal as analog signal.
• Connection to X22.1 with ground potential
The setpoint value is only accepted by the bus module. The controller’s terminal
X22.1 can be directly connected to earth if an alternative operation is excluded.
• Connection to X22.1 is switched
• Thyro-A’s circuit X22.1 is connected to one of the terminals X1.1 to X8.1
of the bus module (Fig. 2). In case of malfunctions on the bus line, the set point
value will be taken automatically from the Power Controller analog input
(2 000 000 848 / 849).
• Thyro-A’s circuit X22.1 is connected to one of the terminals X1.5 to X8.5 of the
bus module (Fig. 2). In case of malfunctions on the bus line, the set point value
will be taken automatically from the Power Controller analog input, as indicated in Chapter 3.2, or the last set point value is held.
Additionally, every controller connected to the bus module can be released by
”hand” (Chapter 3.2 ”set output data=0”).
72
2.7 Additional functions for Thyro-A
Applying the bus module provides access to further data on the controller (e.g. parameters, actual values). It is thus possible to perform additional application functions.
The data, which can be accessed via the bus module, is specified in the corresponding bus module operating instructions.
Examples:
In order to achieve a narrower line width with a line recorder the output signal can
be smoothed as required.

For the operating modes TAKT and VAR control limits (final position limit) can be

If required the controller’s parameters can be adjusted to the route:

(default value)
A function of Thyro-A which is often used in the TAKT operating mode is the software
synchronization (mains load optimization). A numerical value can be entered via INDEX 38 (SYNC_ADR) which is multiplied by 10ms or 8.33ms (duration of a mains
half wave) and results in a delay time up to the first connection.
Mains load optimization with SYNC_ADR
(50Hz) => delay time after mains recovery 10ms * 100 = 1000ms
(60Hz) => delay time after mains recovery 8.33ms * 100 = 833ms
(Default setting: 100)

Thye SYNC address contents of the individual controllers then contain different
values. As a result, the time up to the initial switch-on varies. This makes staggered
switching possible, particularly with the slow pulse time of 1 sec. Values with an
interval of 100 mean a delayed switch-on by one pulse period T0 (group formation).
This function also allows switch-on to, for instance, an emergency power
generator (step-by-step switch-on of the load).

NOTE
The mains load optimizations with SYT9 and QTM are not dependent on connection of a controller to a bus module.

3. Operation
This chapter describes the operating elements of Thyro-A. For default settings see
chapter 8.2.
3.1 Configuration switch S1
A 10-pole DIP switch is situated at the front behind the hood. The individual switches
are marked from 1-10 starting from the bottom and must be set before operation
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
The description of the settings proceeds from the upper (R201) to the lower (R205)
potentiometer. A 19 mm potis with 20 revolutions is being referred to.
A setting guide exists for all potentiometers via the analog output (X2:9 against X2:5
ground). If a poti is changed, this is recognised by the Thyro-A. It then switches the
analog output over so that instead of the actual value, the poti value is read out.
During the setting procedure the red LEDs flicker. As the analog output is designed
for 0-20mA / 10V, 10mA (=5V) = 100% is set. This allows the set points to be read
directly or in a percentage of the nominal value:
Analog output (setting guide)
10
V or
20.0mA =
200%
5
V or
10.0mA =
100% or
100°el.
2.5 V or
5.0mA =
50% or
50°el.
1.25V or
2.5mA =
25% etc.
If the poti is not substantially changed within 30 seconds, the Thyro-A automatically
switches back to the output of the chosen actual value.
3.2.1 Phase angle 1. half wave operation TAKT
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.
76
The soft start time SST is set at the same time. The also applies to the operating
mode VAR. Depending on AN1 the soft start time has the following value:
AN [1°el]

With an 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
T0 = 5 periods without SST.
NOTE
In this configuration the terminal X2.7 can be used as an additional
digital “set point value” (24V d.c.). This also enables the controller to
be driven, for example, by a two-position controller.
Analog output (setting guide)
5 V / 10.0mA = 100 °el (Maximum value)
3 V / 6.0mA = 60 °el
1.5V / 3.0mA = 30 °el
1.25V / 2.5mA =
0 °el
3.2.2 Control end set point input
Potentiometer R202 allows the control characteristic to be adapted to the operation.
In central position the factor is = 1, right-hand stop = 2, left-hand stop = 0.
Default setting.
With set point full modulation (20mA, 10V, 5V see 3.1.4) wird Urms max, i.e. nominal voltage + 10% or Irms max, i.e. nominal current is reached, depending on the
type of underlying control.

3.2.3 Current limitations
Potentiometer R203 enables the load current to be limited to a given value. Default
setting: nominal current as on type plate.
At reduced ambient temperature the controller can be operated with up to 110% of
its nominal current (effective value).
Analog output (setting guide)
5,5 V / 11.0mA = 200% - values 110% are limited to 110%
5
V / 10.0mA = 100%
2.5 V / 5.0mA = 50%
1.25V / 2.5mA = 25%
The permissible peak currents are derived from the fuse layout.
See type table and text: definitions and dimensions of Thyristor Power Controllers.
If the limit has been reached, the red LEDs blink in 1 sec. intervals.
3.2.4 Increased analog output
The analog output is adjusted to 0-20mA. 20mA corresponds to the actual r.m.s. current which corresponds to the maximum permissible current of the Power Controller.
It is possible to adapt with potentiometer R204, e.g. if the scaling does not correspond to the nominal data or the output is set to voltage reading. The increase can
be set to between 0 and 2.
Analog output (setting guide)
Factor Remark
10 V / 20.0mA =

e.g. for 50A scale of a 100A device
5 V or 10.0mA =
1
see previous table
2.0V or
4.0mA =
0.4
e.g. for 100A scale of a 40A device
With voltage display the factor 1 corresponds to 110% of the type nominal voltage.
With output display (H RLP) with Thyro-A 1A the analog output signal corresponds to
Utype * Itype * 1.2.
With output display (H RLP) with Thyro-A 2A the analog output signal corresponds
to the total output of both power paths: Type power * 2 (type power according to
Table 9.1).
NOTE
Control characteristic and limitation Pmax work with Utype * Itype * √3
(enlarged by a factor of 1.2 to permit full drive at 10% overvoltage).
78
3.2.5 Load monitoring (undercurrent monitoring)
Thyro-A is suited for monitoring loads which consist of one or several resistors in parallel or in series parallel connection.
Thyro-A recognises an increase in load resistance. The load monitor works as an
undercurrent monitor and is suitable for application in all operating and control
modes. Load monitoring is delivered with the default setting OFF = left stop R205.
For all other settings the following applies:
If the load current undercuts the set level, the fault relay is released. The incident is
indicated through a bus system which can optionally be installed.
For Thyro-A 1A and Thyro-A 2A (load with separate neutral point without N)
a setting for load monitoring can be made according to the table below:

Value deviations can be converted by percentage. The set monitoring value must
lie “in the middle” between the nominal load current value and the value after
outage.
NOTE
Settings above 90% and below 10% are not practical. If low load currents are required, check if a controller with a lower type current can
be used.
In the VAR operating mode monitoring with large trigger delay angles
140°el. is locked.

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.
4.2 Power supply for the control device
The control device is supplied directly from the power section (terminals U1, X1.1
and X1.2). This voltage also serves as mains synchronization. The mains connection
is equipped for input voltages of UNnom -15% to +10% and nominal frequencies
of 47Hz to 63Hz. Both terminals (X1.1 and X1.2 1.5mm2 grid 3.81) are internally
bridged. If a phase is connected to X1, a fused connection is necessary
(figs. 3,7).
83
4.3 Additional control voltage input
The Thyristor Power Controller Thyro-A is equipped with an additional 24V a.c./d.c.
power supply input (X11.1 and X11.2 1. 5mm2 grid 3.5).
If required, the control device can additionally be supplied with 24V a.c. or d.c.,
when operating with bus, for instance, or with voltages below the tolerance
(e.g. with undervoltage of a 440V supply with a 500V Thyro-A).
When in operation with SELV, the 24V supply must be ungrounded. For EMV reasons a connection with the control ground is not permitted. Several Thyro-A devices
can be operated from a 24V supply. The input is reverse protected. The connection
output for the control device is ca. 2W (5VA) with Thyro-A 1A or 4W (10VA) with
Thyro-A 2A per controller.
The 24V connecting lines must be fuse protected under valid regulations. A soldered
1A fuse protects the device should internal short circuits occur.
4.4 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. A mains outage sets
off the pulse lock internally.
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).
NOTE
The contact for actuating the pulse lock must be light-duty
contact.
4.5 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.
4.6 Digital set point value input
Under particular 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.
84
4.7 Analog output
The electrical values for current and voltage at the load are recorded by the Thyro-A
Power Controller and can be displayed using an external measuring device or a
graph recorder. Connection to terminals X2:9 (+), against X2:5 ground 1.5mm2
grid 3.5. The selectable signal levels are 0-10V, 0-20mA, 4-20mA. The analog output is updated in every supply period (refer to 3.2.4).
The following values may be given:
• load voltage
• load current
• Actual output
4.8 Current transformer
All Thyro-A types have one current transformer per path in their power section.
The current transformer only has local mode wiring.
4.9 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/T0). The voltage transformer only has local mode wiring.

6. 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.
89
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 an additional component. It can also be employed in
connection with controllers already installed of type Thyro-P. 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, T0 = 5 supply periods) as well as a low pulse frequency (T0 = 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, the
Power Controller switches onand the pulse time T0 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 QTM operating mode a 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 T0.
T0 achieve a balance in supply from the outset (not after T0) 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 (refer to 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! (a grounding screw is provided 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 8, 16 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.)
ATTENTION
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 (terminal 4 or by bus option)
• Pulse lock (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!

8.4 Checklist
• LED ON green does not light up
- Check fuse control 500V 1.6A, if defective check external wiring, also applies to
faults of external fusing, check Power Controller fusing.
- If fuse is defective then check load and wiring to load. Synchronization voltage is
supplied to X1.1 supply(load) voltage must also be supplied by 24V current supply.
- With transformer load, check phase angle 1 (TRAFO ADAPTION) - fuse release
caused by rush current is possible if setting is incorrect.
- Check 5V 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 (Poti R203)
- Check all parallel load resistances for current conduction
- Checkthat end control setting is correct
• Load current flows without triggering
- Check that current transformer is correctly connected with I / I2 control (X4)
- Check limit values for correct setting
- Check control characteristic adjustment (U, I, live-zero)
- Check control end for correct setting

13. Approvals and conformities
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
Guidelines
The CE mark on the device confirms observation of the EC general guidelines for
72/23 EEC - low voltage and for 89/339 EEC electromagnetic compatibility if the
instructions on installation and commissioning set out in the operating instructions
are observed.
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).
Additional to the following table 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.
