EMC Guide
In order to help you reduce the effects of electromagnetic interference depending on the product
installation, Eurotherm can supply you with the 'Electromagnetic Compatibility' Installation
Guide (ref: HA025464).
This guide lists the rules generally applicable for EMC.

DECLARATION OF CE CONFORMITY
Availability
A declaration of CE conformity is available on request.
Validation by Competent Body
Eurotherm has validated the compliance of TE300 products with the European Low Voltage
Directive and EMC test standards through product design and laboratory testing.
The tests carried out on TE300 products 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.
DANGER
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
ATTENTION
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 TE300 products 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 TE300 SERIES
The TE300 series of controllers are thyristor units designed to control the electrical power of
industrial three-phase loads.
ATE300 series controller is made up of three channels, each comprising a pair of thyristors
connected in anti-parallel.
The TE300 series is designed to control three-phase resistive loads:
· elements with a low temperature coefficient
· short-wave infrared elements
Three-phase loads can be connected:
· in star with or without neutral
· in open or closed delta
The wiring of the controller is indifferent to the order of the supply phase rotation.
The nominal line-to-line voltage can be selected from 230V to 500V.
The nominal currents of the TE300 series controllers are between 16A and 63A, per phase,
defined at an ambient temperature of 45°C.
Figure 1-1 Current derating per phase as a function of ambient temperature
(dotted line: current limit for recommended fuse)
Attention!
In order to allow for variations in load resistance, the calculated current should not
exceed 0.8 times the maximum rated current of the unit. The load current is
calculated from the supply voltage and the load power (or resistance).

The unit is controlled by analogue or logic signals.
The input analogue signals have two possible voltage ranges: 0 to 5V or 0 to 10V and a current
range of: 4 to 20mA.
The input logic signals have the following nominal values: 5V, 10V or 20mA.
Local control is possible via a potentiometer or external contacts. (The input must be configured
as 0 to 5V code 0V5)
The 5V,0.5mA user-voltage output on terminal 7 and 9 is intended for this purpose.
The electronics of the TE300 controllers are self-supplied from the power voltage and do not
require external connections.
The control method of the TE300 series includes line voltage squared (V2) compensation for
line variations in the range +10% to -15% of the nominal voltage of the controller.
TE300 series controllers have several thyristor firing modes:
- Logic ON-OFF
- Cycle time modulation (Burst-firing with four possible cycle times)
- Advanced Single-cycle (firing by complete cycles separated by a complete number of
half-cycles of non-firing).
Thyristor firing ensures the absence of any DC component in load currents when connected in
open delta or in star with neutral configurations. .
ATE300 series controller is equipped with:
·A‘driver board’ which generates thyristor firing pulses, implements control and
provides power for the electronics. This board is also used for the signal and
operating mode configurations
·A‘filter board’ to ensure Electromagnetic Compatibility in accordance with the test
standard and to protect the controller from transient interference.
The filters which provide immunity against electromagnetic interference are located:
· Between the power phases
· Between the phases and the safety earth connector
The user terminal block below the controller is used for the control signal connection without
having to open the front door of the unit.
A green LED indicating thyristor firing (‘ON’) is located on the front facia.
TE300 power controllers are designed to be bulkhead or DIN rail mounted.
The 63A rated limit must be permanently fan-cooled.
The fan power supply of either 115V or 230V should be specified when ordering the controller.
