Once the desired value has been set, press the key P again: the
new value will be memorised and the display will show only the

code of the selected parameter. 
Pressing the UP and DOWN  keys, it is possible to select another

parameter and change it as described. 
To exit the programming mode, do not press any key for about 20

seconds, or keep the UP or DOWN key pressed until it exits the
programming mode.

2.2 - PARAMETER PROTECTION USING THE PASSWORD

The instrument has a parameter protection function using a
password that can be personalised, through the  

“PASS”

parameter.
If one wishes to have this protection, set the password number

desired in the parameter “PASS”.
When the protection is working, press the P key to access the

parameters and keep it press for about 5 seconds, after which the
LED SET will flash and the display will show “0” .

At this point, using the  UP and DOWN  keys, set the password
number programmed and press the key "P".

If the password is correct, the display will visualise the code that
identifies the first parameter and it will be possible to programme

the instrument in the same ways described in the previous section.
Protection using a password can be disabled by setting the
parameter “PASS” = OFF.

2.3 - PARAMETERS PROGRAMMING LEVELS

The instrument has two parameter programming levels.

The first level (“visible” parameters) is accessed according to the
procedure described above (with or without password request)

while the second level (“hidden” password) can be accessed
according to the following procedure.

Remove the power supply to the instrument, press the key P and
return power to the instrument, keeping the key pressed.

After about 5 sec. the SET led will light up, the display will show the
code that identifies the first parameter and it will be possible to set

the parameters of the instrument using the same programming
procedure described previously.

Once the parameter has been selected and the SET is on, it means
that the parameter can be programmed even on the first level

("visible”). 
If the LED is off it means that the parameter can only be

programmed on this level (i.e. “hidden”).
To change the visibility of the parameter, press the key U: the led

SET will change status, indicating the accessibility level of the
parameter (on = parameter “visible”; off = parameter “hidden”).

The access procedure for “hidden” parameters allows the “PASS”
parameter to be checked and changed, and is useful therefore if
the password set  has been forgotten.

3 - INFORMATION ON INSTALLATION AND USE

3.1 - PERMITTED USE

The instrument has been projected and

manufactured as a measuring and control device to
be used according to EN61010-1 for the altitudes

operation until 2000 ms.

 

The use of the instrument

for applications not expressly permitted by the

above mentioned rule must adopt all the necessary protective
measures. The instrument CANNOT be used in dangerous

environments (flammable or explosive) without adequate
protection. The installer must ensure that EMC rules are respected,

also after the instrument installation, if necessary using proper
filters.

 

Whenever a failure or a malfunction of the device may cause

dangerous situations for persons, thing or animals, please
remember that the plant has to be equipped with additional devices

which will guarantee safety.

3.2 - MECHANICAL MOUNTING

The instrument, in case 33 x 75 mm, is designed for flush-in panel

mounting. Make a hole 29 x 71 mm and insert the instrument, fixing
it with the provided special bracket. We recommend that the gasket

is mounted in order to obtain the front protection degree as

declared. Avoid placing the instrument in environments with very
high humidity levels or dirt that may create condensation or

introduction of conductive substances into the instrument. Ensure
adequate ventilation to the instrument and avoid installation in

containers that house devices which may overheat or which may
cause the instrument to function at a higher temperature than the

one permitted and declared. Connect the instrument as far away as
possible from sources of electromagnetic disturbances such as

motors, power relays, relays, solenoid valves, etc.

3.3 - ELECTRICAL CONNECTION

Carry out the electrical wiring by connecting only one wire to each
terminal, according to the following diagram, checking that the

power supply is the same as that indicated on the instrument and
that the load current absorption is no higher than the maximum

electricity current permitted. As the instrument is built-in equipment
with permanent connection inside housing, it is not equipped with

either switches or internal devices to protect against overload of
current: the installation will include an overload protection and a

two-phase circuit-breaker, placed as near as possible to the
instrument, and located in a position that can easily be reached by

the user and marked as instrument disconnecting device which
interrupts the power supply to the equipment. It is also

recommended that the supply of all the electrical circuits connected
to the instrument must be protect properly, using devices (ex.

fuses) proportionate to the circulating currents. It is strongly
recommended that cables with proper insulation, according to the

working voltages and  temperatures, be used. Furthermore, the
input cable of the probe has to be kept separate from line voltage

wiring. If the input cable of the probe is screened, it has to be
connected to the ground with only one side. Whether the

instrument is 12 V version it’s recommended to use an external
transformer TCTR, or with equivalent features, and to use only one

transformer for each instrument because there is no insulation
between supply and input. We recommend that a check should be

made that the parameters are those desired and that the
application functions correctly before connecting the outputs to the

actuators so as to avoid malfunctioning that may cause
irregularities in the plant that could cause damage to people, things

or animals.

4.1 - MEASURING AND VISUALIZATION

Via the parameter 

“SEnS”

 it is possible to select the type of

probes that one wishes to use and which can be: thermistores PTC

KTY81-121 (Ptc) or NTC 103AT-2 (ntc).
Once the type of probe used has been selected, through the
parameter 

“Unit”, 

 it is possible to select the temperature unit of

measurement (°C or °F) and, through the  parameter 

“dP”

, the

resolution of the desired measurement (OFF=1°; On =0,1°).
The instrument allows the measuring to be calibrated, that can be

used for re-calibrating the instrument according to application
needs, through the parameters 

“OFS”

.

Using the parameter

 “FiL”, 

it is possible to set the time constant

for the software filter for measuring the input values to be able to

reduce the sensitivity to measurement disturbances (increasing the
time).

4.2 - PARAMETERS CONFIGURATION BY “KEY01”

The instrument is equipped with a connector that allows the
