At this point press P, the display show “0”, 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 program the
instrument in the same ways described in the previous section.
Protection using a password can be disabled by setting the
parameter “t.PP” = oF.
Note:
If the Password gets lost, just swith off and on the instrument
supply, push P key during the initial test and keeping the key
pressed for 5 seconds.
In this way it’s possible to have access to all the parameters, verify
and modify the par. “t.PP”.

2.4 - CUSTOMIZED MODE PARAMETER PROGRAMMING
(PARAMETERS PROGRAMMING LEVEL)
The password protection hides all the configuration parameters
behind a factory set password to avoid unwanted changes being
made to the programming of the controller.
To make a parameter accessible without having to enter the
password when “t.PP” password protection is activate follows this
procedure.
Enter the programming using the Password “t.PP” and select the
parameter which is desired to be accessible with no password
protection.
Once the parameter has been selected, if the SET led is blinking,
this means that the parameter is programmable by entering the
password (it’s then “protected”) if it’s instead on, this means the
parameter is programmable without password (not protected).
If you want to change the accessibility of the parameter push P
key, keep it pressed and press together also the key UP.
The led SET will change its state indicating the new access level of
the parameter (on = not protected; blinking = protected by
password).
In case some parameters are not protected, when one tries to have
access at the programming, the display will show all the
parameters not protected and the par.
“r.P”
(through which will be
possible to have access to the “protected” parameters.)

2.5 - RESET PARAMETERS TO DEFAULT VALUE/LEVEL
The instrument allows the reset of the parameters to values
programmed in factory as default.
To restore to the values of default the parameters set the value
-48
to “r.P” password request.
Once confirmed the password with the key P the display it shows "-
--" for 2 sec. therefore the instrument effects the parameters reset..
2.6 - KEYBOARD LOCK FUNCTION
On the instrument it’s possibile to lock completely the keyboard.
This function is particularly useful when the regulator is reachable
by the users and it’s desired to avoid any modification.
To activate the keyboard lock it’s enough program the par.
“t.Lo”
to a different value to oF.
The value program to this parameter it is the time of inactivity of the
keys afterwhich the keyboard will be locked.
Insofar not pressing any key for the time "t.Lo" the instrument
automatically disable the normal functions of the keys.
When the keyboard is lock, if any of the key is pushed, on the
display will appear
“Ln”
to indicate the active lock.
To unlock the keyboard it’s enough to contemporarily push key P
and UP and keep them pushed for 5 sec., afterwhich the label
“LF”
will appear on the display and all the keys functions will be
available again .
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 EN60730-1 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 instrument used with NTC 103AT11 probe (identifiable by the
printed code “103AT-11” visible on the sensor part) is compliant
with standard EN 13485 ("Thermometers for measuring the air and
product temperature for the transport,storage and distribution of
chilled, frozen, deep-frozen/quick-frozen food and ice cream”) with
the following classification: [EN13485 air, S, A, 2,- 50°C +90°C]
Remember that the end user must periodically checks and verify
the thermometers in compliance with standard EN 13486.
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 78 x 35 mm, is designed for flush-in panel
mounting. Make a hole 71 x 29 mm and insert the instrument, fixing
it with the provided special brackets. 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
