CAUTION

Thyristor units are used in power industrial equipment. When the thyristor unit is working, there
are on the unit the following voltages

- Maximum main supply voltage on power terminals up to 600V.

- Auxiliary supply 230-460Vac.

- Fan voltage 230Vac 50/60Hz Power consumption 14W.
Don't remove the plastic cover which provides adequate protection against electric shock.
Don’t use this thyristor in aerospace and nuclear application.

Electric Shock Hazard

When thyristor unit has been connected to main supply voltage and is switched off, before to touch
it be secure that the unit is isolated and wait at least one minu te to permit to discharge internal
capacitors. Thus be secure that:

• access to thyristor unit is only permitted to specialized personnel;

• the authorised personnel must read this manual before to have access to the unit;

• the access to the units must be denied to unauthorized personnel.

Important warnings

• Local regulations regarding electrical installation should be rigidly observed.

• Safety regulations must be rigidly observed.

• Don't bend components to maintain insulation distances.

• Protect the units from high temperature, humidity and vibrations.

• Don't touch components to prevent elettrostatichal discharges on them.

• Verify that all ratings are in line with real needs.

• If authorized personnel must measure voltage, current etc. on units, take away rings and other

jewels from fingers and hands.

• Authorized personnel working on thyristor unit under power supply voltage must work on
insulated board. Be secure that board is not connected to earth.

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

Protection

CD3000 thyristor family has a polymeric plastic cover in compliance to International specification
IP20. To understand if IP20 protection is sufficient should be evaluated the installation place where
the units are installed.
Open Type Equipment.
Maximum surrounding air temperature 40°C.

Earth

CD3000 family has isolated heatsink. For safety connect the heatsink to earth to avoid shocks in
case that circuit board or thyristors lost insulation. Earth impedance should be correspondent to
local earth regulation. Periodically the earth efficiency should be inspected.

Electronic Supply

CD3000 family electronic circuit should be supplied by dedicated voltage supply for all electronic
circuit but not in parallel with contactor's coil, solenoids and other inductive or capacitive loads. It's
recommended to use a shielded transformer.

Electromagnetic compatibility

Our thyristor unit has an excellent immunity to electromagnetic interferences if all suggestions
contained in this manual are respected. In respect to a good Engineering practise, all inductive
loads like solenoids contactor coils should have a filter in parallel.

Emissions

All thyristor switching at high speed generate some radiofrequency disturbance. CD3000 serie
complies with EMC rules for CE mark. In many installations near electronic devices has not been
noted problems. If radiofrequency device at low frequency are used near the thyristor unit, some
precautions should be taken like line filters and shielded cables for input signal an d for load cables.

1.Glossary

1.1 Terminology

V: voltage power supply.
I: the full circulating current in thyristor unit.
P: total load power.

1.2 Input signal

SSR: This input type is a square waveform generated by a temperature controller.
AN: Analog input.
IRS: Communication command.

1.3 Power feed back

Feedback: supply voltage fluctuation changes the power to the load. To overcome this effect the
voltage supplied to the load is measured and compared with power demand from controller, the
error signal is used to automatically hold the power at demanded level.

1.4 What is a thyristor unit

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

6.4 Heater Break Alarm

Heater Break Alarm is a microprocessor based circuit to diagnose partial or total load failure and
short circuit on SCR and fuses failure.

• discrimination better than 20%;

• latching alarm plus reset;

• relay output 0.5A at 125VAC.

Minimum current 3A. If load current is below this value make two turns or more
around current transformer. H.B. circuit also diagnose fuse failure.

H.B. circuit reads load current via a current transformer 25-50/0.05 or 100/0.05 depending on
thyristor size.

6.4.4 Calibration

This procedure it’s necessary to give set point to Heater Break. CD3000M reads the load current
many times and when the value is the same for three times takes it as set point.

Calibration procedure:

• verify that connections are correct;

• supply the thyristor unit;

• push “CAL” button on front of CD3200 unit,

or supply with 24Vdc terminals 1-2 or send command via RS485;

• the thyristor unit goes in conduction state to measure load current;

• all LEDS are ON, this means that calibration procedure is active;

• after one minute LEDS for H.B. and S/C switch off (calibration procedure is done);

• the thyristor unit is ready to work.

If load current decreases for partial or total load failure (sensitivity 20% standard adjustable v ia
RS485) the yellow LED becomes ON and alarm relay changes status.
If CD3200 is still in conduction with no input signal (LED green OFF) it means that there is a short
circuit on thyristors and red LED (SC) becomes ON.

The diagnostic is active only when the switching period is longer than 60ms (3 main
voltage cycles).

If the load has been changed calibration procedure must be done again.

7.1 Phase Angle + Current Limit (PA)

With Phase Angle is possible to control the power to the load allowing to Thyristor to be in
conduction for a variable part of the voltage supply halt cycle. The load power can be adjusted
from 0 to 100% as a function of analog input signal, normally delivered by temperature controller
or by potentiometer. Normal it's used with inductive loads. The only disadvantage with phase
angle is the generation of interferences that can be reduced with filters.

10.Modbus communication

The CD3200 is equipped with two-wire RS485-compatible serial communications, by
which means communication may occur between the Controller and a master device
(e.g. a computer or terminal).

10.1 Physical requirements

10.1.1 Character Transmission

Data format is fixed to be one start bit, eight data bits, one stop bit, baud rate 9600 and the parity
none.

10.2 ModBus RTU protocol

The standard RS485 Communications uses the industry standard MODBUS RTU protocol.
The following restrictions are imposed:

• Baud rates is fixed to 9600 Baud only.

• Support for multi-parameter Write operations is limited to support of the Multi-

Word Write Function (Number 16) but it permits the writing of only one
parameter per message.

The following MODBUS functions are supported:

Function Function Number
Read Holding Registers (Read n Word) 03
Preset Multiple Registers (Write n Word) 16

The Controller will identify itself in response to a Read Holding Registers message which enquires
the values of word parameters 121 and 122 (see Table 4-2).
MODBUS Function 17 (Report Slave ID) is not supported.

10.2.1 Message Formats

The first character of every message is the Controller address, in the range 1 - 255 and 0 for
broadcast messages.
The second character is always the Function Number.
The contents of the remainder of the message depends upon this Function Number.
In most cases the Controller is required to reply to the message by echoing the address and
Function Number.

Broadcast messages are supported at address 0 (to which the CD3000M responds by
taking some action without sending back any reply).

Data is transmitted as eight-bit binary bytes with one start bit, one stop bit and parity checking set
to none. A message is terminated simply by a delay of more than three character lengths at the
Baud rate used(in this case 9600 baud); any character received after such a delay is considered to
be the potential address at the start of a new message.

User’s Manual ver. 2.0 CD3200 up to110A Honeywell

37 www.honeywell.com/imc

Since only the RTU form of the protocol is supported, each message is followed by a two-byte
CRC 16 (a 16-bit cyclic redundancy checksum).
This checksum is calculated in accordance with a formula which involves recursive division of the
data by a polynomial, with the input to each division being the remainder of the results of the
previous division.

The dividing polynomial is
2

16

+ 215 + 22 + 1(Hex 18005)

but this is modified in two ways:

• because the bit order is reversed, the binary pattern is also reversed, making the most
significant bit (MSB) the right-most bit;

• because only the remainder is of interest, the right-most (most significant) bit can be
discarded.

Thus, the polynomial has the value Hex A001.

10.2.2 Bit’s order

Normal bit order

Most significant bit Least significant bit

Most significant byte Least significant Byte

Reversed bit order

Least significant bit Most significant bit

Least significant Byte Most significant byte

N.B.: Reversed order apples, so CRC16 return Reversed bit order

{

}
else
{

}
}

}
return (crc);
}

10.2.4 Read Holding Registers (Read n Words) – Function 03

The message sent to the Controller to obtain the value of one or more registers comprises the
following eight bytes:

Addr. unit Func. Address

1° word

N° of Word CRC 16

3

3Hex

HI LO HI LO HI LO

The normal reply will echo the first two characters of the message received follow ed by a single­byte data byte count (which will not includ e itself or the CRC).
For this message, the count value equals the number of parameter v a lues read multiplied by two.
Following the byte count, the specified number of parameter values are transmitted, followed by
the CRC16 bytes:

Addr. unit Func. Cont. 1° Value Last Value CRC 16

3

3Hex

HI LO HI LO HI LO

Honeywell CD3200 up to110A User’s Manual ver. 2.0

www.honeywell.com/imc 40

10.2.5 Preset Multiple Registers (Write n Words) - Function 16

This is an eleven-byte message. only one parameter may be written for each received message.
The usual pre-amble is followed by the address of the parameter to be written, a two-byte word
count (always set to 1), a single-byte byte count (always set to 2), the value to be written and
the CRC16 bytes:

Addr. unit Func. Addr of

1° Word

N° of Word Cont. Valore CRC 16

16

10Hex

HI LO 0 1 2 HI LO HI LO

The Controller normally responds with the following eight-bit reply:

Addr. unit Func. N° of Word N° Word CRC 16

16

10Hex

HI LO 0 1 HI LO

10.2.6 Error and Exception Responses

If a received message contains a corrupted character (parity check failure, framing error etc.) or if
the CRC16 check fails, or if the received message is otherwise syntact ically flawed (e.g. byte count
or word count is incorrect), the thyristor will ignore that message.

If the received message is syntactically correct but nonetheless contains an illegal value, the
thyristor will send a five-byte exception response as follows :

Addr. unit Func. N.Exception CRC 16

HI LO

The Function Number byte contains the function number contained in the message which caused
the error, with its top bit set (i.e. Function 3 becomes 0x83) and the Exception Number is on of
the following codes:

Code Name Cause
1 ILLEGAL FUNCTION Function number out of range
2 ILLEGAL DATA ADDRES Parameter ID out of range or not supported
3 ILLEGAL DATA VALUE Attempt to write invalid data/required action not

executed

NOTE: Writing a parameter value equal to its current value is a valid transaction; this will
not cause an error response.

11.2 Repairing procedure

• Phone to us.

• Explain to Service Engineer the problem because sometimes it can be solved with a phone call.

• If this is not possible ship the unit to us or to your distributor.

• Write a fault description and give the name of your personnel to which refer.

• Use a rugged packaging to ship the unit.

11.3 Fans

The thyristor unit with forced ventilation uses fans that rotate permanently when the unit is
supplied. In case of accidental fan failure, there is an over heating temperature on heatsink. In this
case to give protection to thyristor there is a thermal switch properly setted. The function of this
switch is to open the input signal until the h eatsink temperature falls below the setted value. This
means that also with input signal in ON condition the unit is switched OFF and the system can not
work at full power. For these reason is important to control periodically the fan status checking
that is rotating.

11.4 Servicing

In order to have correct cooling, the user must clean the heatsink and the protective grill of fan.
The frequence of this servicing depends on environmenta l pollution.
Check periodically also if the screw for the power cables and safety earth are tightened correctly

11.5 Warranty conditions

We gives a 12 months warranty to its products. The warranty is limited to repairing and parts
substitution in our factory and does exclude products not properly used and fuses.
Warranty does not includes products with serial numbers deleted. The faulty product should be
shipped to us at your cost and our Service will evaluate if product is un d er warranty terms.
Substituted parts remains our property.
