1Important warnings for safety

This chapter contains important information for the safety. The not observance of these instructions may

result in serious personal injury or death and can cause serious damages to the Thyristor unit and to the

components system included.

The installation should be performed by qualified persons.

The Thyristor unit are integral part of industrial equipments. When it is supply, the

Thyristor unit is subject to dangerous tensions.

Don't remove the protection Cover.

Don't use these unit in aerospace applications and/ or nuclear.

The nominal current corresponds to use at temperature not superior to 45°C.

The Thyristor unit must be mounted in vertical position and without obstruction above

and below to allow a good flow ventilation.

The hot air of one thyristor unit must not invest the unit positioned above.

For side by side placed leave a space of 15mm between the unit.

A suitable device must ensure that the unit can be electrically isolated from the supply, this

allows the qualified people to work in safety.

Protection (Protection, Protezione)

The unit have IP20 protection rating as defined by the specific international. Is necessary

consider the place of installation.

Earth (Terre, Messa a terra)

For safety, the Thyristor unit with isolated heat-sink must be connected to earth.

Earth impedance should be correspondent to local earth regulation. Periodically the earth

efficiency should be inspected.

Electronic supply (Alimentation électronique, Alimentazione elettronica)

The electronic circuit of the Thyristor unit must be supplied by dedicated voltage for all

electronic circuits and not in parallel with coil contactors, solenoids and other.

It's recommended to use a shielded transformer.

Electric Shock Hazard (Risque de choque électrique, Rischi di scosse elettriche)

When the Thyristor unit is energized, after the power supply is shut off, wait least a minute

for allow the discharge of the internal capacitors where there is a dangerous tension. Before

working, make sure that:

Only authorized personnel must perform maintenance, inspection, and replacement

operations.

The authorized personnel must read this manual before to have access to the unit.

Unqualified People don't perform jobs on the same unit or in the immediate vicinities.

Important warnings (Attention, Avvertenze importanti)

During the operations with units under tension, local regulations regarding electrical

installation should be rigidly observed:

Respect the internal safety rules.

Don't bend components to maintain insulation distances.

Protect the units from high temperature humidity and vibrations.

Don't touch components to prevent electrostatic discharges on them.

Verify that the size is in line with real needs.

To measure voltage current etc. on unit, remove rings and other jewels from fingers

and hands.

Authorized personnel that work on thyristor unit under power supply voltage must be

on insulated board

This listing does not represent a complete enumeration of all necessary safety cautions.

Electromagnetic compatibility

(Compatibilità électromagnétique, Compatibilità elettromagnetica)

Our thyristor units have an excellent immunity to electromagnetic interferences if all

suggestions contained in this manual are respected. In respect to a good Engineering

practice, all inductive loads like solenoids contactor coils should have a filter in parallel.

Emissions (Emission, Emissioni)

All solid-state power controllers emit a certain amount of radio-frequency energy because of

the fast switching of the power devices.

The CD Automation’s Thyristor unit are in accord with the EMC norms, CE mark.

In most installations, near by electronic systems will experience no difficulty with

interference. If very sensitive electronic measuring equipment or low-frequency radio

receivers are to be used near the unit, some special precautions may be required. These

may include the installation of a line supply filter and the use of screened (shielded) output

cable to the load.

Note

Warning: This icon is present in all the operational procedures where the Improper

operation may result in serious personal injury or death

Caution: This icon is present in all the operational procedures where the Improper

operation can cause damage for the Thyristor unit.

CD Automation reserves the right to modify the own products and this manual without any

advise.

2Introduction

A thyristor unit is semiconductor device which acts as a switch formed by two thyristors in ant parallel.

To switch on the alternating current the input signal will be on and the thyristor will switch off at first

Zero Crossing voltage with no input signal.

The benefits of thyristor units compared with elettromechanical contactors are numerouses: no moving

parts, no maintenance and capacity to switch very fast. Thyristors are the only solution to control

transformers and special loads that change resistance with temperature and with age.

2.1 Advantages compared with analog thyristor unit

REVO E is an universal Thyristor unit, designed to control resistive or inductive loads including three

phase transformers. The electronic circuit is completely digital and is based on a powerful

microprocessor with high performance that allow the use in different ways:

Single cycle

Burst Firing with soft start

Delayed triggering

Phase Angle with soft start

On same unit can be used different feed back that define the control mode:

Voltage

Current

Power VxI

External 0÷10Vdc

On same unit can be used different input:

4÷20mA

0÷10Vdc

Potentiometer 10KΩ

SSR

2.2 Software Configurator

The software configuration is free and is possible

download it from our site:

www.cdautomation.com

If the Order Code is in line with requirement, then

REVO E has been already configured in Factory and

it's ready to use.

You need the software only to modify the ordered

configuration. Anyway we suggest to check the

unit on the machine with the "Test unit" section.

For install the software, launch the program and

follow the instructions on the screen.

To connect the unit at the PC, it's necessary use

the USB\TTL converter connected between the unit

and the USB port of the PC.

USB\TTL converter need a driver to work properly,

you can find it from our site.

Is available a full programmer kit composed by

USB\TTL converter,

Two cable

Thyristor configurator software

USB driver.

3Quick Start

Caution: this procedure must be performed only by qualified persons.

If the Order Code of the Thyristor unit is in line with what you really need, then REVO E has been

already configured in Factory and you just need to do the following steps:

1. Verify the REVO E Sizing. Making sure that:

The load current is equal or less than the MAX current of REVO E.

The load voltage is equal or less than the MAX voltage of REVO E.

(see par. 4)

2. Verify the Order Code

(see par. 5.2)

3. Verify the Installation

(see par. 6)

4. Verify the Diagram of control connection:

All auxiliary connections must be done in line with wirings on this manual.

Verify that there isn’t a short circuit on the load.

(see par. 7.4)

5. Supply the Electronic boards

(see Order Code)

6. If not specified in the Order Code:

Set the Load Voltage in the parameter P116 .

Set the Load Current in the parameter P119 .

7. With Burst Firing (BF) or Heater Break Alarm (HB)

make the Calibration procedure

(see par. 9.4)

The REVO E Thyristor unit is ready to start.
