1.0 General

The range of REOTRON MDW Thyristor Regulators are microprocessor based units for controlling the
power to resistive and inductive loads. In essence the units comprise inverse parallel connected power
semiconductors (thyristors) and the control and regulation electronics. The units have a regulated, AC
output. The inverse parallel connected thyristors operate as contact free, power controllers using the
phase angle control or the full wave principles. In the phase angle control mode the equipment can be
used as a voltage or current regulator and also there is an option for power regulation. The set point value
for the current and voltage can be provided by an external control voltage of 0-10 V, 0(4)-20 mA, DC or a
potentiometer. The lowest set point has priority. The effective value is fed back internally from a voltage
or current transformer. The maximum current limit of the unit cannot be exceeded in all regulation modes,
using phase angle control. Applications with a wide load resistance variation Rcold/Rwarm are possible,
and an overloading of the unit is prevented.

Typical Applications

Industrial Ovens Steam Generators Lighting Installations
Infra Red Emitters (Dryers) Preheating Plants Air Conditioning Plant
Tunnel Heaters Room Heating Equipment Fan Heating Systems
Plastic Moulding Equipment Extruders

2.0 Construction

The REOTRON -MDW 700 thyristor controller is a completely functional, compact, unit. It has been de­signed for building into an enclosure. All connections for the supply, power output, feedback signals and
the supply for the isolator are made through screw terminals. A touch panel with an LED display and set­ting up keys is incorporated in the front panel. There are connectors provided for analogue signals and
optional a field bus interface. Inside the unit there is a printed circuit, control card and a power card, com­prising the semiconductors, firing and regulating circuits and the system power supply.

3.1 Modes

Phase angle control

In the phase angle control mode the mains voltage half waves are more or less cut in function of the giv­en set point.
This mode of operation is suitable for resistive, inductive and resistive-inductive loads.
The benefits with this mode of operation are the continuous adjustment, the fine dosing and the high
regulating dynamics. A dynamic current limitation is possible only with this mode of operation.

Full wave control

In the full wave principle mode of operation, always full sinus waves are switched in function of the set
point. In this operating mode almost no harmonics are produced, however, the dynamic regulation is not
possible. This mode of operation is suitable in particular for loads with high thermal inertia.

3.2 Regulation mode

The REOTRON MDW Thyristor Regulator range include 3 regulators, ie. voltage, current and power
regulator. All the regulators always work in combination, ie. with voltage regulation for example, the cur­rent regulation operates like a cascade control and limits the output current in case of overload on the
rated current. In case of current regulation mode, the maximum voltage limit can be prescribed over the
voltage set point. With power regulation, the current limit is also effective as cascade.
In case both the voltage and current regulation are used, the set point of the power regulator must be set
to 100 % (over display, in menu „C 002“, parameter „P“).

Voltage regulation

Microprocessor controller with PI Characteristics; the P portion is adjustable externally by using the key­Pad. The units maximum voltage output is factory set to the rated voltage (for 100% set point).

Power regulation

With power regulation, the real power value is controlled. In this case, the input that is normally coordi­nated to the voltage set point is now used as set point input. This set point input corresponds to 0...100
% of the unit output power. The current set point must be set to 100 % or to the required limit value. Set­ting over display or link between terminals 7 and 8.

3.4 Feedback

Current feedback

The current is measured, in one phase, with an internal current transformer. The internal microprocessor
determines the effective value of the output current and makes adjustments through a PI loop.

Voltage feedback

The effective voltage is measured with an internal Transformer. It is converted in an analogue input stage
and then fed to the internal microprocessor. The effective value is thus determined and applied used for
PI regulation using software.
Using an external feedback signal of 0..5V is also possible. (See connection diagram)

Output monitor

Effective Voltage 0…10 V, DC correspond 0…100 % output voltage or output power.
Effective Current 0…10 V, DC correspond 0…100 % output current

3.5 Control functions

Enable

Run / Stop input.
A control voltage (24V DC) must be applied to terminals 32(+) and 31(-), to enable the unit, or a connec­tion made between terminals 32 and 33 by using a switch. A permanent link between terminals 32 and 33
is used for operation without an external enable. The firing pulses are inhibited whilst the enable input is
not closed.

Start ramp / Stop ramp

This function reduces surges on the mains supply
when the load is switched on and off.

Set point control (min / max)
The set-point control characteristics can be
adjusted to match the subsequent process
controller or automation system, by setting the
lower and upper values

Status / Ready relay (clamp 41, 42, 43)

For monitoring the actual status, an internal relay can be used. In case of applied input voltage and ena­bled power output, clamp 42 – 43 closes.

For using this relay as a “READY” signal point “r.b.” in Code “C 003” has to be set to 1. In case of an error
like “LO.PO.”, clamp 42 – 43 opens.

7.0 Operation

The six buttons and a LED display found in the front panel,
are used for operating and setting up the unit. All operating
methods and adjustable parameters can be set up through
this panel.

The “I“ and “O“ buttons are used for switching the unit
ON and OFF, however, these do not provide mains isola­tion, they simply inhibit the power semiconductors

The “P“, “F“ and “Cursor Buttons“ are used for parameter
adjustment. Parameters are set by using menu controls
which are called up by entering operator codes. A capital
letter is used to indicate the selected function.
The display value can be increased or decreased by units, or
tenths of units, by a short press of the cursor buttons. Holding
the buttons down will cause the display to change in units of
ten.

7.1 Adjustment

To prevent accidental or unauthorized adjustment the adjustment parameters, in the user menus, are
protected. A code must be entered to open the user menus. There are different pass codes for each func­tion group.

Setting adjustments are automatically saved upon leaving the programming mode or if no button
is pressed for a period of 100 seconds.

7.2 Adjustment Procedure

All setting routines are commenced by pressing the programming button “P“. The following diagram
should clarify the sequence in which keys are pressed:

1. Press the “P“ key.

2. Select the code number with the cursor keys.

3. Press the “P“ key. This displays the first menu point. The required menu point can be found by re-

peatedly pressing the “P“ key (scrolling).

4. The value in the menu point can be changed with the cursor keys.

5. Scroll to the next menu point or to the end of the menu, which returns the display to the set point val-

ue, by pressing the “P“ key. To exit the menu and return back to the normal display quickly, depress
the “P“ key for 5 seconds.

6. To return back to the previous position in the menu, press the “F“ key

12.0 Putting into service

Safety Instruction

Qualified personnel only, are permitted to install electronic equipment

Because attenuation capacitors (Y-capacitors) are used, leakage current flows through the case to pro­tective earth (PE). Therefore, units must be earthed.

12.1 Preliminaries

• Check if the local supply voltage is the same as the rated voltage for the unit (rating plate) and that the
load is within the permitted power range.

• Connect the control unit in accordance with the connection diagram.

• Adjust set-points to zero.

• Switch off enable (if used)

• Check if cables are connected correctly.

The control unit is now ready for operation and can be switched on (power supply, enable).
The unit is factory set according to the rating plate i.e. 100% set point equals 100% voltage, cur­rent or power.

Set-point control only can be used, in which case no other settings are necessary.

12.2 Measurements and Settings

Because of the phase-angle-control, the shapes of the supply voltage and current sine curves are
changed. The output voltage and current must be measured with effective value meter (true-RMS).

12.3 Putting into service without a proper load

A thyristor can only be switched ("fired") into a conducting state, if the current level is sufficiently high
enough. It will only switch-off, if the current is lower than the threshold current (every time the current
goes through the zero-crossing point). When the thyristor controller is put into service, without a proper
load, realistic measurements such as the voltage, for example, cannot be obtained. Even the setting of
the output current i.e. limit, can only be done with a proper load and not by short circuiting the output of
the thyristor controller. This is because the thyristor, once “fired”, cannot be turned off. The current has to
pass through "zero" for the thyristor to switch off. Using a low impedance load it is not possible to evalu­ate the current level from the internal current flow.
If a proper load is not available or not possible to carry out the correct commissioning procedure then a
makeshift test can be carried by connecting a resistive load, such as incandescent lamps to the output of
the thyristor controller.

13.0 Installation of Thyristor Control Units

13.1 Fuses

The REOTRON MDW... series of thyristor controllers are fitted with semiconductor fuses, which protect
the power semiconductors (thyristors) from damage when there is a short-circuit on the output. These
fuses are selected for the permitted peak current of the semiconductors and are not provided for protec­tion against overload or line faults! Fuses are provided only in the current-carrying circuits with thyristors.

Fuses for overload, line and earth fault protections should be fitted to the incoming power side.

13.2 Incoming breaker

An isolator must be connected in front of a thyristor-controller, mounted inside a control panel (VDE
0160/6.3.1) because of the leakage-current from a high-impedance thyristor and hence the current flow
through the protection circuit. This can be used to disconnect the unit from mains supply before a routine
shut-down.
Because all REOTRON thyristor-controllers have an enable input, it is possible to inhibit the input pulses,
and hence firing of the thyristors, until the main contactors have securely closed or before the contactors
open again when shutting down.
When enable inputs are used in this way, the contactors can be rated for current-free switching, in which
case AC1 would be suitable. If direct-on-line switching is used i.e. by switching the thyristor controller,
without using the enable, the rating of the contactors must be in accordance with AC3.

13.3 Output Breaker

A circuit-breaker on the output of the thyristor controller should be avoided, because it cannot operate
without a load. Current or voltage monitoring in the output of the thyristor controller must be used to con­trol the circuit-breaker at the input side.
Current-free switching of the thyristor controllers’ output (e.g. load switching) is possible, however, by
using the enable input.

13.4 Installation and climatic Conditions

The mounting base should be free of vibration, if possible. Note that the temperature of the heat-sink
rises when a power controller is operating. The heat-sink must be mounted vertically to ensure efficient
cooling. The ambient temperature range allowed below the heat-sink is 0°...+45°C. The relative air hu­midity is < 75% without dew. The clearance below the unit should be at least100mm and above at least
150mm. There must be a clearance of 50mm between units mounted next to each other. For altitudes
above 1000m the power must be derated by 0,5% per 100m additional height.

13.5 Signal cables

Set Points
If external voltage (0...10V) or current (0(4)...20mA) set-points are used; care should be taken to ensure
that all equipment is connected through equal-potential bonding. If the bonding is earthed, then this
should be at a single point, thus avoiding earthing loops and possible coupled interference.

REOTRON MDW 700
Operating instructions

24

14.0 Interference prevention

14.1 Earthing

Correct earthing of electronic controls is highly important for two reasons:
First it ensures the safety of operators and service personnel, and secondly it provides a fail-safe opera­tion of the equipment. Therefore, in addition to providing protective earthing, in accordance to DIN stand­ards, it also provides an earth path for pulse interference produced during operation. For the latter, con­trollers that are mounted onto a chassis–plate in a control panel should be bonded to earth with the
shortest possible connection and the largest possible earth contact area and also, for example, onto the
centrally bonded chassis-plate. The reason for this is to ground high-frequency interferences produced by
switching on the mains (contactors, relays, switches) before they cause fault conditions. If the earth con­ductors are too long and if they run together with other cables, in one cable duct, then they are unsuitable
for grounding high-frequency noise.
The more complex the unit and the more "intelligent" the functions - especially serial bus connections –
then the more important it is to use correct earthing techniques.

14.2 Control cables

Control cables also are "antennas" that receive interference produced by other loads. Signal cables that
are run alongside power cables can generate voltage spikes through inductive and capacitive cross­coupling. Therefore control conductors should not be mixed with power cables in the same cable ducting.
If this cannot be avoided then shielded cables should be used. In particular cables from inverters to mo­tors are very critical because of the presence of high-speed switching. There should be maximum dis­tance between control cables output cables from frequency inverters. The shielding around the control
conductors should be grounded onto a large contact area (earthed mounting plate) at the equipment end.

14.3 Interference protection of other external components and equipment

Contactors produce extreme Burst-interferences on switching. Contactor coils must be connected with

RC-snubbers. Suitable RC-snubbers can be obtained from switch manufacturers.
Magnets / magnetic valves are also interference sources in the same way as contactors. RC- snubbers

and varistors can be components and varistors can be connected across these components

Frequency inverters are to connect to a mains filter recommended by the manufacturer.
Motor wires should be shielded and routed away from control cables.
