MOUNTING REQUIREMENTSMOUNTING REQUIREMENTS

MOUNTING REQUIREMENTS

Select a mounting location where there is

minimum vibration and the ambient temperature

range between 0 and 50 °C.

The instrument can be mounted on a panel up to

15 mm thick with a square cutout of 45 x 45 mm.

For outline and cutout dimensions refer to Fig. 2.

The surface texture of the panel must be better

than 6,3 μm.

The instrument is shipped with rubber panel gasket

(50 to 60 Sh).

To assure the IP65 and NEMA 4 protection, insert

the panel gasket between the instrument and the

panel as shown in fig. 1.

While holding the instrument against the panel

proceed as follows:

1) insert the gasket in the instrument case;

2) insert the instrument in the panel cutout;

3) pushing the instrument against the panel, insert

the mounting bracket;

4) with a screwdriver, turn the screws with a

torque between 0.3 and 0.4 Nm.

NOTE:

1) Don’t run input wires together with power

2) Pay attention to the line resistance; a high line

resistance may cause measurement errors.

3) When shielded cable is used, it should be

grounded at one side only to avoid ground loop

currents.

4) The input impedance is equal to:

< 5 Ω for 20 mA input

> 1 MΩ for 60 mV input

LOGIC INPUT

Safety note:

1) The "serial comunication" and the "logic input"

options are mutually exclusive.

2) Do not run logic input wiring together with

power cables.

3) Use an external dry contact capable of

switching 0.5 mA, 5 V DC.

4) The instrument needs 100 ms to recognize a

contact status variation.

5) The logic inputs are isolated by the measuring

input

NOTENOTE

NOTE:

1) Before connecting the instrument to the power line,

make sure that line voltage and the load current are

in accordance with the contact rating (3A/250V AC

on resistive load).

2) To avoid electric shock, connect power line at the

end of the wiring procedure.

3) For servomotor connections use No 16 AWG or

larger wires rated for at last 75 °C.

4) Use copper conductors only.

5) Don’t run input wires together with power cables.

6) For feedback potentiometer, use shielded cable

with the shield connected to the earth at one point

only.

7) The relay outputs are protected by varistor

against inductive load with inductive compo-

nent up to 0.5 A.

All relay outputs are protected by varistor against

INDUCTIVE LOADSINDUCTIVE LOADS

INDUCTIVE LOADS

High voltage transients may occur when switching

inductive loads.

Through the internal contacts these transients may

introduce disturbances which can affect the

performance of the instrument.

The internal protection (varistor) assures a correct

protection up to 0.5 A of inductive component.

The same problem may occur when a switch is

used in series with the internal contacts as shown

in Fig. 10.

Fig. 10 EXTERNAL SWITCH IN SERIES WITH THE

INTERNAL CONTACT

In this case it is recommended to install an

additional RC network across the external contact

as shown in Fig. 10

The value of capacitor (C) and resistor (R) are

shown in the following table.

Anyway the cable involved in relay output wiring

must be as far away as possible from input or

communication cables.

SERIAL INTERFACESERIAL INTERFACE

SERIAL INTERFACE

RS-485 interface allows to connect up to 30

devices with one remote master unit.

Fig. 11 - RS-485 WIRING

The cable length must not exceed 1.5 km at 9600

BAUD.

The "serial comunication" and the "logic input"

options are mutually exclusive.

NOTE:The following report describes the signal

sense of the voltage appearing across the

interconnection cable as defined by EIA for

RS-485.

a) The ” A ” terminal of the generator shall be

negative with respect to the ” B ” terminal for

NOTE:

1) Before connecting the instrument to the power

line, make sure that line voltage corresponds to the

descrtiption on the identification label.

2) To avoid electric shock, connect power line at the

end of the wiring procedure.

3) For supply connections use No 16 AWG or larger

wires rated for at last 75 °C.

4) Use copper conductors only.

5) Don't run input wires together with power cables.

6) For 24 V DC the polarity is a do not care condition.

7) The power supply input is fuse protected by a sub

miniature fuse rated T, 1A, 250 V.

When fuse is damaged, it is advisable to verify the

power supply circuit, so that it is necessary to send

back the instrument to your supplier.

8) The safety requirements for Permanently Con-

nected Equipment say:

- a switch or circuit-breaker shall be included in the

building installation;

- It shall be in close proximity to the equipment and

within easy reach of the operator;

- it shall be marked as the disconnecting device for

the equipment.

NOTE: a single switch or circuit-breaker can drive

more than one instrument.

INSTRUMENT CONFIGURATION

1) Switch on the instrument.

The upper display shows the measured value while

the lower display shows the programmed set point

value (we define the above condition as “normal

display mode”).

2) Push "FUNC" pushbutton and, maintaining the

pressure, push the "MAN" pushbutton for more

than 4 seconds.

The lower display will show

ConF while the

upper display will show

C.mOn.

NOTENOTE

NOTE: two different configuration mode are

possible:

A)

Monitor modeMonitor mode

Monitor mode: in this mode it is possible

to monitor but not to modify the configuration

parameter. During the monitor mode the

instrument continue to perform the standard

control.

B)

Modify modeModify mode

Modify mode: in this mode it is possible to

verify and to modify all configuration

parameter.

3) By  and  pushbuttons select the

C.mOd

indication (modify mode).

4) Push the "FUNC" pushbutton.

NOTESNOTES

NOTES:

1) When modify mode is started, the instrument

stops the control action and:

- sets control outputs to OFF;

- sets alarms in no alarm condition;

- disables the serial link.

2) If the configuration parameters are protected by

security code the display will show:

By  and  keys enter a value equal to the

configuration security code (see P51 parameter)

or the master key code (see appendix A).

Note:Note:

Note: the master key code allows to enter in modify

configuration parameters mode either if the

configuration security code is lost or if the configu-

ration parameters are always protected (P51 = 1).

When it is desired to exit from configuration modify

mode proceed as follows:

a) Push "FUNC" or "MAN" push-button more times

until the

C.End parameter is displayed.

b) Pushing ”” or “” push-button select the

yes

indication.

c) Push “FUNC” push-button. The instrument ends

the configuration modify mode, preforms an

automatic reset and restarts in the run time

mode.

Two special function are driven by this parameter:

1) When the instrument detects an alarm condition

it waits for 6.5 s before to activate or de-

activate the alarm. If the alarm condition

changes during this time, the alarm will not be

activated or de-activated otherwise it will

operate as usual.

2) When the instrument detects a very high overrange

(like for OPEN TC), it will mask this alarm.

This parameter is available when P7 is different

from none, rEU or dir.
