1 Introduction
1.4 Brief description
Device The JUMO TYA 202 represents the consistent development of the JUMO pow-
er controller technology. It switches ohmic-inductive loads using a threephase current economy circuit in star-delta three-phase operation. The microprocessor-controlled power controller shows all parameters in an LCD display
with background lighting and is operated by 4 keys at the front.
Application SCR power controllers are used where larger resistive and ohmic-inductive
loads have to be switched (e.g. in industrial kiln construction and plastics processing). The SCR power controller consists of SCRs connected in anti-parallel, the insulated cooling body, and the control electronics.
Mounting SCR 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
Load types All resistive loads and transformer loads are permitted.
Subordinate

Standards The SCR power controllers are in accordance with VDE 0160 5.5.1.3 (5/88)
Advantages - Teach In function for the detection of partial load failure
The TYA 202 works in burst firing mode.
In burst firing mode, the first half-wave can be optimally cut with an adjustable
phase angle so that transformer loads can also be operated.
It is possible to specify a base load or, depending on the device type, set current limiting or resistance limitation for the load.
To avoid high starting currents, a softstart can be set.
Depending on the device type, U, U

and VDE 0106 Part 100 (3/83). The system must be grounded as specified by

2 Installation
Safety regulations
Fuse protection k Fuse protection of the supply lead in accordance with the VDE regulations
k The 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.
k The electrical connection must only be carried out by qualified personnel.
k An 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 starting internal work.
k Inside the device, safety clearances meet the requirements for double insu-
lation.
When fitting the connecting cable, ensure that the cables are fitted according to regulations and that the safety clearances are maintained.
must be installed when wiring the voltage supply in the power section. The
supply protection can also be achieved by a circuit-breaker in the supply
lead. The circuit-breaker must correspond to the power consumption of the
power controller.
k For 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.
k To protect the power controller in the event of an earth fault, a semi-con-
ductor fuse is installed. In the event of a defect, these may only be replaced
with original JUMO semi-conductor fuses.
v Chapter 8.2 "Replacing a defective semi-conductor fuse"
Wiring Supply voltage and control cables are to be wired isolated from one another.
For supply protection, fuses (e.g. 2 A Neozed) must also be installed in the
control circuit.
PE connection h A direct connection must be provided between the PE conductor of 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 conductors to the power section. In the event
that the protective conductor is not a component of the supply lead or its encasement, the selected conductor cross section may not be less than
2.5 mm

this safety isolation, all connected electrical circuits must also have safety isolation. The required auxiliary voltages must be safe extra-low voltages.
2.1.1 Ambient conditions
Incorrect use The device is not suitable for installation in potentially explosive atmospheres.
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
Avoid additional
sources of heat
Power dissipation
- 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
- 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 (kiln)
- Avoid direct sunlight.
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 accordance with the climatic conditions.

To prevent radio-frequency interference, such as occurs with a soft start in
phase angle control, electrical apparatus and systems must have interference
suppression implemented.
The control electronics of the SCR power controller correspond to the EMC requirements of EN 61326.
However, electrical modules such as SCR power controllers do not have any
purpose by themselves. They provide a function as part of a complete system
or installation.
Where applicable, the entire load circuit of the power controller must also have
suitable interference suppression filters fitted by the system provider.
There are a number of specialist companies that provide appropriate ranges of
filters to deal with any interference problems. Such filters are normally supplied as complete modules that are ready to be connected.

Destruction through overheating:
In the event of operation over a long period at maximum load current, the cooling body and its environment heats up.
For this reason, at ambient temperatures above 45 °C, the maximum load current must be reduced as shown in the image, as the SCR module could otherwise be destroyed.
The master or slave device temperature shown on the display may not exceed
100 °C.
If a device temperature exceeds 100 °C, the message "Warning - high temperature" is displayed.
If a device temperature exceeds 105 °C, the load current is gradually reduced
by 10 % of the rated current each time the temperature increases by one degree.
If a device temperature exceeds 115 °C, the power controller current is completely switched off.

height
In the case of air cooling, it must be noted that the effectiveness of the cooling
is reduced the higher up the device is installed. As a result, the current carrying
capacity of the SCR power controller decreases with such a cooler as the installation height increases as shown in the image.

Hot
surface
The power controller heats up during operation to a maximum of
110 °C, depending on the load.
Ensure that the lamellae of the cooling body are vertically aligned to
allow the heat to be dissipated through natural convection.
Fire hazard:
Do not install any heat-sensitive components or devices close to the
power controller.
Integrated ventilator for 250 A power controller:
The intake air at the ventilation grid of the ventilator may not exceed a maximum supply air temperature of 35 °C. Ensure that the
inlet air for the built-in ventilators can be taken in from below and
escape at the top without obstruction!
2.1.5 Mounting on DIN rail (accessories)
Power controllers up to 32 A can be affixed to a DIN rail using the corresponding accessories.

h Swivel the power controller downward until the lug engages with the DIN
rail with an audible click.
