1 Introduction
14 V3.01/EN/00561073 [thyristor power controller TYA 202]
1.4 Brief description
Device The JUMO TYA 202 represents the consistent development of JUMO power
controller technology. It switches ohmic-inductive loads using a three-phase
current economy circuit in star-delta three-phase operation. The microproces-
sor-controlled power controller displays all parameters in an LCD display with
background lighting. It can be operated using the 4 keys at the front.
Application Thyristor power controllers are used where larger resistive and ohmic-induc-
tive loads have to be switched (e.g. in industrial furnace construction and plas-
tics processing). The thyristor power controller consists of thyristors connect-
ed in anti-parallel, the insulated heat sink, and the control electronics.
Mounting Thyristor power controllers up to a load current of 32 A can either be clipped
to a 35 mm mounting rail or fitted to the wall on a mounting plate. Devices with
a load current greater than 32 A can only be mounted on the wall.
Operating
modes The TYA 202 works in burst-firing operation. In burst-firing operation, the first half-wave can be optimally cut with an adjustable phase angle so that trans-
former loads can also be operated.
It is possible to specify a base load or, depending on the device type, to set
current limiting or resistance limitation for the load.
To avoid high starting currents, a soft start can be set.
Load types All resistive loads through to inductive loads are permitted.
In the case of transformer loads, the nominal induction of 1.2 tesla must not be
exceeded (value is 1.45 T in the case of mains overvoltage).
Subordinate
control loop Depending on the device type, U, U2, I, I2, or P controls are available as subor-
dinate control loops. Fluctuations in the mains voltage therefore have no effect
on the control-loop regulation during operation.
Standards The thyristor power controllers comply with VDE 0160 5.5.1.3 (5/88) and VDE
0106 Part 100 (3/83). The devices must be grounded as specified by the re-
sponsible energy supplier.
Advantages - Teach-In function for the detection of partial load failure
- Network load optimization through dual energy management
- Transmission of the setup data is possible even without voltage supply to
the device (power supply via USB port)

2.1 Important installation notes
Safety
regulations kThe choice of cable material, the installation, and the electrical connection of the device must conform to the requirements of VDE 0100 "Regulations
on the Installation of Power Circuits with Nominal Voltages below AC
1000 V" or the appropriate local regulations.
kThe electrical connection must only be carried out by qualified personnel.
kAn isolating switch should be wired between the voltage supply and the de-
vice to be able to disconnect the device from the voltage supply on all
poles prior to accessing the inner parts of the device.
kInside the device, safety clearances meet the requirements for double insu-
lation.
When mounting the connecting cable, ensure that the cables are fitted ac-
cording to regulations and that the safety clearances are maintained.
Fuse protection kFuse protection of the voltage supply in accordance with the VDE regula-
tions must be installed when wiring the voltage supply in the power section.
The supply can also be protected with a circuit-breaker in the supply lead.
The circuit-breaker must correspond to the power consumption of the pow-
er controller.
kThe connecting cables used for the terminals U1, U2, N/L2, V, and L1 must
have an electric strength of AC 500 V.
kFor UL application, it must be ensured that the fuse for the supply protec-
tion of the control electronics is between 2 A and a maximum of 5 A. This
also applies to the fan connection.
kA semiconductor fuse is installed to protect the power controller in the
event of a ground fault. In the event of a defect, these may only be replaced
with original JUMO semiconductor fuses.
vChapter 8.2 "Replacing a defective semiconductor fuse"
Wiring Control cables (SELV potential) must be routed so that they are isolated from
cables with mains voltage potential. For supply protection, fuses (e.g. 2 A,
Neozed type) must also be installed in the control circuit.
Master/slave
1:1 patch cable Prior to startup, the enclosed 1:1 patch cable must be inserted into the mas- ter's X8 socket and connected to the slave device's X8 socket.
PE connection hA direct protection conductor connection must be provided between the
power controller and the PE conductor of the supply network. Connection
takes place at the PE connection terminal.
The cross section of the PE conductor must be at least as large as the cross
section of the voltage supply cables in the power section. In the event that the
protection conductor is not a component of the supply cable or its encase-
ment, the selected conductor cross section may not be less than 2.5 mm2(for
mechanical protection) or not less than 4 mm2(if the protection conductor is
not protected mechanically).

Check hThat the data on the nameplate (rated mains voltage, load current) corre-
sponds to the data for the plant.
hThat the rotary electrical field has clockwise phasing if the economy circuit
configuration is used.
hThat the configuration of the analog inputs, for example, corresponds to the
wiring.
hThe analog input for the setpoint specification only needs to be connected
to the master. The slave receives its information via the 1:1 patch cable.
However, the slave power controller can be disconnected separately by
means of its own inhibit input.
Load connec-
tion hThe electronic switch (2 anti-parallel thyristors) is located between the U1 and U2 terminals.
hWhere possible, load cables and cables for control inputs should be routed
so that they are isolated.
hConnect the mains voltage - thyristor power controller - load in accordance
with the connection diagram and check.
Phasing The voltage supply of the control electronics and the load voltage
must have the same phase.
Control inputs The terminal strips for control connections (inputs and outputs) have been laid
out for safe isolation from the mains voltage (SELV). To prevent the safe isola-
tion from being impaired, ensure that all connected current circuits are also
safely isolated. The required auxiliary supplies must be SELV voltages.
The ground terminals X2_2/11 or X2_1/6 of the master and slave must be con-
nected to one another.
2.1.1 Environmental conditions
Incorrect use The device is not suitable for installation in potentially explosive areas.
Mounting site The power controller must be installed in a fire-proof control cabinet.
The cabinet should be vibration-free, free from aggressive media, and free
from dust to prevent the ventilation slots from becoming blocked.
Climatic
conditions - Relative humidity: 5 to 85 %, no condensation (3K3 according to EN 60721)
- Ambient temperature range: 0 to 45 °C (3K3 according to EN 60721-3-3)
- Storage temperature range: -30 to +70 °C class 1K5
Avoid additional
sources of heat - Ensure that the ambient temperature at the installation site is not increased
by other sources of heat or heat accumulation.
- Do not mount the power controller too close to the heating process (fur-
nace)
- Avoid direct sunlight.
Power loss Occurs as waste heat on the cooling body of the master and slave device and

must be dissipated at the mounting site (e.g. in the control cabinet) in accor-
dance with the climatic conditions.
2.1.2 Filtering and interference suppression
To prevent radio-frequency interference, generated with a soft start in phase-
angle operation for example, electrical apparatus and plants must have inter-
ference suppression implemented.
The control electronics of the thyristor power controller comply with the EMC
requirements of EN 61326.
However, modules such as thyristor power controllers do not have any pur-
pose by themselves. They only serve as a component function within a plant.
Where applicable, the power controllers's entire load circuit must also have
suitable interference suppression filters fitted by the plant provider.
There are a number of specialist companies that provide appropriate ranges of
interference suppression filters to deal with any interference problems. These
filters are normally supplied as complete modules that are ready to be con-
nected.

Site altitude In the case of air cooling, it must be noted that the effectiveness of the cooling
is reduced as the site altitude increases. As a result, the ampacity of the thyris-
tor power controller decreases with such a cooler as the site altitude increas-
es, as shown in the diagram.
A
Destruction through overheating:
In the event of operation at maximum load current over an extended period,
the heat sink and its surroundings heat up.
For this reason, at ambient temperatures above 45 °C, the maximum load cur-
rent must be reduced as shown in the image, as the thyristor module could
otherwise be destroyed.
The master or slave device temperature shown on the display may not exceed
100 °C.
At a device temperature of >100 °C, the message "Warning - high tempera-
ture" is displayed.
At a device temperature of >105 °C, the load current is gradually reduced by
10 % of the nominal current each time the temperature increases by one de-
gree.
At a device temperature of >115 °C, the power controller current is completely
switched off.
