NOTES

ON ELECTRIC

SAFETY AND

ELECTROMAGNETIC

COMPATIBILITY

.

Please, read carefully these instructions before proceeding with
the installation of the controller.
Class II instrument, rear panel mounting.

This controller has been designed with compliance to:
Regulations on electrical apparatus (appliance, systems and installa­tions) according to the European Community directive 73/23 CEE amend­ed by the European Comunity directive 93/68 CEE and the Regulations
on the essential protection requirements in electrical apparatus EN 61010­1 (IEC 1010 - 1) : 90 +A1:92 + A2:95.

Regulations on Electromagnetic Compatibility according to the
European Community directive n089/336/CEE, amended by the European
Community directive n° 92/31/CEE and the following regulations:
Regulations on RF emissions
EN50081 - 1 residential environments
EN50081 - 2 for industrial environments
Regulation on RF immunity
EN500082-2 for industrial equipment and system

It is important to understand that it’s responsibility of the installer to ensure
the compliance of the regulations on safety requirements and EMC.

The device has no user serviceable parts and requires special equipment
and specialised engineers. Therefore, a repair can be hardly carried on
directly by the user. For this purpose, the manufacturer provides techni­cal assistance and the repair service for its Customers.
Please, contact your nearest Agent for further information.

All the information and warnings about safety and electromagnetic
compatibility are marked with the

B sign, at the side of the note.

1 INSTALLATION

Installation must only be carried
out by qualified personnel.

Before proceeding with the instal­lation of this controller, follow the
instructions illustrated in this man­ual and, particularly the installation
precautions marked with the B
symbol, related to the European
Community directive on electrical
protection and electromagnetic
compatibility.

B

To prevent hands or metal touch­ing parts that may be electrically
live, the controllers must be
installed in an enclosure and/or in
a cubicle.

PRECAUTIONS

B

Despite the fact that the instrument
has been designed to work in an
harsh and noisy environmental
(level IV of the industrial standard
IEC 801-4), it is strongly recom­mended to follow the following
suggestions.

A

All the wiring must comply with the
local regulations.

The supply wiring should be rout­ed away from the power cables.
Avoid to use electromagnetic con­tactors, power relays and high
power motors nearby.
Avoid power units nearby, espe­cially if controlled in phase angle

Keep the low level sensor input
wires away from the power lines
and the output cables.
If this is not achievable, use shield­ed cables on the sensor input, with
the shield connected to earth.

Notes:

1] Make sure that the power supply

voltage is the same indicated on
the instrument.

2] Switch on the power supply only

after that all the electrical con­nections have been completed.

3] In accordance with the safety reg-

ulations, the power supply switch
shall bring the identification of the
relevant instrument. The power
supply switch shall be easily
accessible from the operator.

4] The instrument is protected with

a 0.2 A

~ T fuse. In case of fail-

ure it is suggested to return the
instrument to the manufacturer
for repair.

5] To protect the instrument internal

circuits use:

- 2 A

~ T fuses for Relay outputs

- 1 A

~ T fuses for Triac outputs

6] Relay contacts are already pro-

tected with varistors.

Only in case of 24 V ~ induc-

tive loads, use model A51-065­30D7 varistors (on request)

2.3.4 PV CONTROL INPUT

B

• Connect the wires with the
polarity as shown

• Use always compensation cable
of the correct type for the ther­mocouple used

• The shield, if present, must be
connected to a proper earth.

• If a 3 wires system is used, use
always cables of the same
diameter (1mm

2

min.)
(line 20 Ω/lead maximum resis­tance)

• When using a 2 wires system, use
always cables of the same diam­eter (1,5mm2min.) and put a
jumper between terminals 5 and 6

A When the distance between the

controller and the sensor is 15
mt. using a cable of 1.5 mm

AL2 alarm
threshold

The alarm occurrences handle the
OP1 and OP2 outputs, in different
ways, according to the configured
types of alarms, as illustrated.

Proportional
band

This parameter specifies the pro­portional band coefficient that mul­tiplies the error (SP - PV)

Integral
time

It is the integral time value, that

#t.i.

#p.b.

#A2s.p

#AIs.p

specifies the time required by the
integral term to generate an output
equivalent to the proportional term.
When Off the integral term is not
included in the control algorithm.

Derivative
time

It is the derivative term coefficient that
specifies the time required by the pro­portional term P to reach the level of
D. When Off the derivative term is
not included in the control algorithm.

Control output
cycle time

It’s the cycle time of the time propor­tioning control output. The PID con­trol output is provided through the
pulse width modulation of the digital
waveform.

Overshoot
control

This parameter specifies the span
of action of the overshoot control.
Setting lower values (0.99 —> 0.01)
the overshoot generated by a
Setpoint change is reduced. The
overshoot control doesn’t affect the

Input shift

the address range is from 1 to 247
and must be unique for each con­troller on the communication bus
to the supervisor.

4.6 CONFIGURATION

The configuration of the controller
is specified through a 4 digit code
that defines the type of input, of
control output and of the alarms.
(sect. 3.2 pag16)
Other parameters specifie the type
of auxiliary functions.

Press S or G to display the next
parameter or the next code and
change its value.
The new value entered is stored
into the controller when the next
parameter is selected by pressing
R.

TUNE

Start/stop of the Fuzzy Tuning
The Tuning operation can be
started or stopped any time.

The green led 3 goes on when the
Fuzzy Tuning is in progress. At the
end of this operation, the calculat­ed PID terms parameter are stored
and used by the control algorithm
and the controller goes back to the
operator mode. The green led 3
becomes off.
This function allows the calculation
of the optimal PID terms parame­ters, monitoring the response of the
process to disturbances.
The controller provides 2 types of
“one shot” tuning algorithm, that are
selected automatically according to
the process condition when the
operation is started.

Step response

This type is selected when, at the
start of the autotune operation, the
PV is far from the Setpoint of more
than 5% of the span.
This method has the big advantage
of fast calculation, with a reasonable
accuracy in the term calculation.

Natural frequency

This type is selected when the PV is
close to the SP setpoint.

This method has the advantage of
a better accuracy in the term cal­culation with a reasonable speed
calculation.

The Fuzzy Tuning determines
automatically the best method to
use to calculate the PID term,
according the process conditions.
