Safety Instructions
Chapter overview
This chapter contains the safety instructions you must follow when installing, operating and servicing the
thyristor power controller. If ignored, physical injury or death may follow, or damage may occur to the thyristor
power controller or the connected equipment. Read the safety instructions before you work on the unit.
To which products this chapter applies
The information is valid for the whole range of the product DCT880.
Usage of warnings and notes
There are two types of safety instructions throughout this manual: warnings and notes. Warnings caution you
about conditions, which can result in serious injury or death and/or damage to the equipment, and advice on
how to avoid the danger. Notes draw attention to a particular condition or fact, or give information on a
subject. The warning symbols are used as follows:
Dangerous voltage warning warns of high voltage, which can cause physical injury or death
and/or damage to the equipment.
General danger warning warns about conditions, other than those caused by electricity, which
can result in physical injury or death and/or damage to the equipment.
Electrostatic sensitive devices warning warns of electrostatic discharge, which can damage
the equipment.
Installation and maintenance work
These warnings are intended for all who work on the thyristor power controller, the cables or the connected
equipment. Ignoring the instructions can cause physical injury or death and/or damage to the equipment.
WARNING!
Only qualified electricians are allowed to install and maintain the thyristor power
controller!
− Never work on the thyristor power controller, the cables or the connected equipment when
main power is applied. Always ensure by measuring with a multimeter (impedance at least
1 Mohm) that:
1. Voltage between thyristor power controller input phases U1, V1, W1 and the frame is
close to 0 V.
2. Voltage between thyristor power controller output phases U2, V2, W2 and the frame is
close to 0 V.
− Do not work on the control cables when power is applied to the thyristor power controller or
to the external control circuits. Externally supplied control circuits may cause dangerous
voltages inside the thyristor power controller even when the main power on the thyristor
power controller is switched off.
− Do not make any insulation resistance or voltage withstand tests on the thyristor power
controller.
− Isolate the cables to the equipment from the thyristor power controller when testing the
insulation resistance or voltage withstand of the cables or the equipment.
− When reconnecting the cables to the equipment, always check that the U2, V2 and W2
cables are connected with the proper terminal.
Notes:
− The output phase cable terminals on the thyristor power controller are at a dangerously high
voltage when the main power is on.
− Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V) may be
present on the relay outputs of the thyristor power controller (e.g. XRO1 … XRO3).
− DCT880 with enclosure extension: Before working on the thyristor power controller, isolate
the whole thyristor power controller system from the supply.

Grounding
These instructions are intended for all who are responsible for the grounding of the thyristor power controller.
Incorrect grounding can cause physical injury, death and/or equipment malfunction and increase
electromagnetic interference.
WARNING!
− Ground the thyristor power controller, the connected equipment and adjoining devices to
ensure personnel safety in all circumstances, and to reduce electromagnetic emission and
pick-up.
− Make sure that grounding conductors are adequately sized and marked as required by safety
regulations.
− In a multiple thyristor power controller installation, connect each thyristor power controller
separately to protective earth (PE
).
− Minimize EMC emission and make a 360° high frequency grounding (e.g. conductive
sleeves) of screened cable entries at the cabinet lead-through plate.
Notes:
− Power cable shields are suitable as equipment grounding conductors only when adequately
sized to meet safety regulations.
− As the normal leakage current of the thyristor power controller is higher than 3.5 mAAC or
10 mADC (stated by EN 50178, 5.2.11.1), a fixed protective earth connection is required.
Printed circuit boards
These instructions are intended for all who handle the circuit boards. Ignoring the following instructions can
cause damage to the equipment.
WARNING!
The printed circuit boards contain components sensitive to electrostatic discharge. Wear a
grounding wristband when handling the boards. Touch the boards only when necessary.

Mechanical installation
These notes are intended for all who install the thyristor power controller. Handle the unit carefully to avoid
damage and injury.
WARNING!
− DCT880 sizes T4 and T5: The thyristor power controller is heavy. Do not lift it alone. Do not
lift the unit by the front cover. Place units T4 and T5 only on its back.
− Make sure that dust from drilling does not enter the thyristor power controller when installing.
Electrically conductive dust inside the unit may cause damage or lead to malfunction.
− Ensure sufficient cooling.
− Do not fasten the drive by riveting or welding.
Operation
These warnings are intended for all who plan the operation of the thyristor power controller or operate the
thyristor power controller. Ignoring the instructions can cause physical injury or death and/or damage to the
equipment.
WARNING!
− Before adjusting the thyristor power controller and putting it into service, make sure that all
connected equipment is suitable for operation throughout the voltage/current range provided
by the thyristor power controller.
− Do not control the connected equipment with the disconnecting device (disconnecting
mains); instead, use the control panel keys
the thyristor power controller.
− Mains connection
and
, or commands via the I/O board of
You can use a disconnect switch (with fuses) to disconnect the electrical components of the
thyristor power controller from the mains for installation and maintenance work. The type of
disconnect switch used must be as per EN 60947-3, Class B, so as to comply with EU
regulations, or a circuit-breaker type which switches off the load circuit by means of an
auxiliary contact causing the breaker's main contacts to open. The mains disconnect must be
locked in its "OPEN" position during any installation and maintenance work.
− EMERGENCY POWER OFF buttons must be installed at each control desk and at all other
control panels requiring an emergency off function. Pressing the Stop button on the control
panel of the thyristor power controller will not cause an emergency off by the thyristor power
controller and it will not disconnect the thyristor power controller from any dangerous
potential.
− To avoid unintentional operating states, or to shut the unit down in case of any imminent
danger according to the standards in the safety instructions it is not sufficient to merely shut
down the drive via signals Run or Enable or from control panel or PC tool.
− Intended use
The operating instructions cannot take into consideration every possible case of
configuration, operation or maintenance. Thus, they mainly give such advice only, which is
required by qualified personnel for normal operation of the machines and devices in industrial
installations.
If in special cases the electrical machines and devices are intended for use in non-industrial
installations - which may require stricter safety regulations (e.g. protection against contact by
children or similar) - these additional safety measures for the installation must be provided by
the customer during assembly.
Note:
− When the control location is not set to Local (Local not shown in the status row of the
display), the Stop key on the control panel will not stop the thyristor power controller. To stop
the thyristor power controller using the control panel, press the Loc/Rem key and then the
Stop key
.

General information
Power controller can be operated in phase angle control of in burst mode.
Phase angle control
+ fast control response
- bad power factor
Burst mode
+ power factor = 1 and no harmonics in the line current
- slow control response
A multitap configuration is built on a single phase transformer with two or three tappings plus a power
controller. Operation mode is phase angle control but with reduced harmonics and improved power factor
compared to pure phase angle control.
The dimensioning of the voltage and the amount of tappings is made according to the operation range.
The picture below shows the relationship between output voltage and power factor.
The green line is the power factor for pure phase angle control.

Power factor with different tappings configurations
The power controller can be configured on the primary side or secondary side of the transformer. Application
and electrical datas will define the location of the power controller. Glass furnaces typically need to avoid DC
components in the load current, therefore typically a transformer is used.
In such case, the transformer can be configured and built with tappings. If the typical operation range is 60 %
to 100 % (operated with high power factor) of output voltage UTrsec then the power controller is located on the
primary side.

Comparisons of primary and secondary controlled configurations
Primary controlled configuration
Secondary controlled configuration
Primary controlled configurations must be dimensioned according to the voltage of highest primary tapping
voltage UTrpr1
.
Secondary controlled configurations must be dimensioned according to the maximum load current of the
highest load current IR.
Primary controlled configurations are good options, if the operating range (using optimal power factor) is
limited. That means highest tapping voltage UTrpr1 is not above the rated voltage of the power controller.
Secondary control is a good option, if the load voltage UR is about the same level as the input voltage UL1.

Primary controlled Multitap
If the power controller is located on primary side of transformer, the name is also called primary controlled
multitap configuration. The diagram below shows a multitap configuration with 3 legs inside the power
controller.
The Leg2 (V1-V2) is optional. The configuration can be operated with only two legs (Leg1 and Leg3).

Control principle of multitap
The control loops of a multitap power controller can be:
−
−
−
Voltage control (open loop or closed loop)
Current control
Power control
The power controller operates the firing angle so that the RMS output voltage of the transformer follows the
reference and the power factor is optimized.
The DCT880 reference of Leg1 is used and connected to either the current-, voltage- or power controller.
For resistive loads on the secondary side, the most simple configuration is the U alfa open loop control or U²
alfa open loop control.
The output of the controllers Leg1 are feeding to point B
The diagram shows the control principle of multitap firing
The reference of connection point B is splitted into three firing branches. The sharing is based on calculation
of parameter 29.01 for Leg1, parameter 29.02 for Leg2, parameter 29.03 for Leg3.
If Leg2 is not connected / taping not available, then parameter is set 29.02 = 0
The paramter 29.03 should be set to 100 % and the other parameters 29.01 and 29.02 are set according to
the transformers ratio.
Now all their legs are operated between their firing angle limits and according to the transformers ratio.

Control principle of primary controlled multitap configurations
The diagram below shows the how the power controller legs are connected to the primary tappings and how
the firing angle of the different tappings are operated.
The blue voltages numbers are examples.
Diagram shows the relationship between transformer tapping and output voltage
If reference is ramping up, then the power controller starts to fire the highest tapping connected to Leg1
(U1-U2). This tapping UTrpr1 has the highest transfer ratio that means smallest output voltage.
If the firing angle of Leg1 has reached 0° then firing of Leg2 will start.
If the firing angle of Leg2 has reached 0° then firing of Leg3 (W1-W2) will start. The Leg3 tapping has the
smallest transfer ratio and thus the highest output voltage.
Table summary primary controlled
Leg1 (U1-U2)
Leg3 (W1-W2)

If Leg3 is in operation and fired with alfa = 0° then the full supply voltage UL1 is connected to UTrpr3 = (e.g.
100 V). Then transformer will create on the other legs higher voltages (e.g. 150 V, 300 V) according the
transfer ratio, even if Leg1 and Leg2 are not fired. All legs must be dimensioned for the full transformer
voltage.
Attention:
The voltage dimensioning rule of the power controller must be according to the full transformer voltage of the
highest tapping UTrpr1
.

Primary control hardware connection and control feedback
Primary controlled connection and the control loops
The DCT880 features feedback for current, voltage and power.
If the measurement configuration parameters are set according the hardware connections, then all physical
values are correct.
Power feedback:
The power on the secondary side can not be measured. The DCT880 calculates the physical power on
primary side according to input current and input voltage. In case of minor transformer losses, the power on
the primary side is the same as on the secondary side.
Voltage feedback:
DCT880 has a function to calculate the output voltage based on supply voltage and firing angle. The
estimation refers to primary tapping 3. The tapping 3 voltage has strong relation in comparison to load voltage
and supply voltage based on transfer ratio.
There is also the possibility to measure the true voltage of Leg3 and use this as a feedback for the voltage
control loop of Leg1 multitap control (use X60:1 voltage measurement feedback).
Current feedback:
The DCT880 built in CT`s can measure current only on the primary side of the transformer. The individual leg
current has no relationship to the load current IR. DCT880 has a mode to calculate the output current of
transformer based on the three individual leg current which show an image of secondary current IR.
The 100 % current is the full load current of transformer taping 3 (W1 – W2).

Three phase multitap control
DCT 880 multitap configuration can be connected to a three phase transformer and operated as three phase
multitap configuration.
Three phase mutlitap is based on three times multitap configuration each phase has its own multitap control.
It can be configured as three phase primary controlled or three phase secondary controlled multitap.
Primary controlled:
The transformer output configuration is typically a star configuration. The star point can be connected or three
independent load circuits can be configured.
In case of primary controlled the unbalance of transformer has to be avoided and give a certain limitation on
allowed control modes.
Current control of primary three phase multitap configuration can be very unbalanced and is not
recommended.
Secondary controlled
Secondary controlled configuration require a delta winding on primary side. This will offer individual operation
points for each winding

firing angle of the master. Forward of reference and monitoring of followers is communicated via XD2D master
follower bus.
The ON OFF Logic is handled from master and communicated via XD2D bus.
The LOCAL operation (composer PC tool or Control panel) of Master will also operate the followers.
If panel bus interface SDCS HDPI is used and one control panel Or one Composer is connect to all three
DCT880 the parameter panel bus node number (49.01) must be unique.
The synchronization of the DCT880 system time will give a correct time stamp in the fault logger of all three

How to use [OTHER] function:
if the write pointer selection is done via [OTHER] function, then the setting of data type (16 bit) must be set
according to the target signal data type.
Example for send XD2D M/F data to PID Feedback
Send XD2D 16 bit data word (e.g. 62.03) to 32 bit Data storage real32 (e.g. 47.01)
