For an industrial environment only, must not be used in domestic environments.
Eurotherm certifies that TE200Aproducts, installed and used in compliance with these
Instructions, meet the following EMC standards and enable the system which incorporates
them to comply with the EMC Directive, as far as the TE200Aproducts are concerned.
EMC test standards
Immunity Generic standard : EN 50082-2
Test standards : EN 61000-4-2, EN 61000-4-4, ENV 50140, ENV 50141
ENV 50204
Emission Generic standard : EN 50081-2

the corresponding test standard.
EMC Guide
In order to help you reduce the effects of electromagnetic interference depending on the prod-
uct installation, Eurotherm can supply you with the 'Electromagnetic Compatibility'
Installation Guide (ref: HA 025464).
This guide lists the rules generally applicable for EMC.

DECLARATION OF CE CONFORMITY
A declaration of CE conformity is available on request.
Validation by Competent Body
Eurotherm has validated the compliance of TE200Aproducts with the European Low Voltage
Directive and with EMC standards through product design and laboratory testing.
The tests carried out on TE200Aproducts are listed in a Technical Construction File validated
by the LCIE (Central Laboratory for the Electrical Industries), a Recognised Competent Body.
Further information
For any further information, or if in doubt, please contact Eurotherm Controls where qualified
staff are available to advise or assist you with the commissioning of your installation.

PRECAUTIONS
Safety symbols
Important safety precautions and special information are indicated in the text of the manual by
two symbols:
This symbol means that failure to take note of the information given in this manual
may have serious consequences for the safety of personnel and may even result in
electrocution.
This symbol means that failure to take note of the information may
• have serious consequences for the installation or
• lead to the incorrect operation of the power unit.
These symbols must be observed for particular points.
However the whole of the manual remains applicable.
Personnel
The installation, configuration, commissioning and maintenance of the power unit should
only be carried out by personnel qualified and trained to work with low voltage electrical
equipment in an industrial environment.
Independent alarm
Given the value of the equipment controlled by TE200Aproducts it is the responsibility of the
user, and it is highly recommended, that an independent safety device (alarm) should be
installed. This alarm must be tested regularly.
Eurotherm can supply suitable equipment.

Chapter 1 IDENTIFYING THE CONTROLLERS
GENERAL INTRODUCTION TO THE TE200A SERIES
The TE200Aseries of controllers are thyristor units designed to control the electrical power in
industrial three-phase loads.
ATE200Aseries controller is made up of two channels, each comprising a pair of thyristors
connected in anti-parallel, and a direct (unswitched) channel.
The TE200Aseries is designed to control three-phase resistive loads:
• elements with a low temperature coefficient
• short-wave infrared elements (except for the 63A model).
Three-phase loads can be connected:
• in star without neutral
• in closed delta
The wiring of the controller is independent of the supply phase rotation.
The nominal line-to-line voltage ranges¡ from 200Vac to 500Vac.
The nominal currents, defined at an ambient temperature of 45°C, of TE200Aseries
controllers are between 16A and 63A, per phase.

TE200A User manual1-4
Two-phase control of three-phase loadsIDENTIFYING THE CONTROLLERS
The unit is controlled by analogue signals.
The analogue input signals have two voltage ranges: 0 to 5V or 0 to 10V, and one current
range: 4 to 20mA.
Local control is possible via a potentiometer (10kΩ).
The +5V user-voltage output is provided for this purpose.
The electronics of TE200Acontrollers are self-supplied from the power voltage and do not
require external connections (unless specified otherwise).
The control function for TE200Aincludes line voltage squared (V2) compensation for line
variations in the range ±10% of the nominal voltage of the controller; stability is better than
±2%.
TE200A series controllers have two thyristor firing modes:
• Burst-firing - the modulation cycle is from 30 cycles at 50% power (15 cycles ON,
15 cycles OFF) to a modulation time of approx 6 seconds at very low and very high power
demands.
• Single-cycle (one cycle of firing and one cycle of non-firing at 50% power).
ATE200Acontroller is equipped with:
• A‘driver board’which implements the control function and EMC filtering, and provides
power for the electronics. This board is also responsible for the input signal and operating
mode configurations.
• A ‘firing board’which triggers thyristor firing.
The filter which provides immunity against electromagnetic interference is located between
the power phases.
The user terminal block below the controller is used for the input signal connection without
needing access to the inside of the controller.
A green LED, labelled ‘ON’, indicates thyristor firing and is located on the front facia.
TE200A power controllers are designed to be bulkhead or DIN rail mounted.
The 63A rated unit must be permanently fan-cooled.
The fan power supply is 115Vac or 230Vac (to be specified when ordering the controller).
