2 - PROGRAMMING
FAST PROGRAMMING OF THE SET POINT - Press the key P
then release it and the display will show SP 1 alternating with the
corretta
set value. To change it press the UP key to increase the value or
DOWN to decrease it. Exiting the Set mode is achieved by
pressing the P key or automatically if no key is pressed for 15
corretto
seconds.
PROGRAMMING OF THE SET POINT AND OF THE HIGH
TEMPERATURE THRESHOLDS - To access the instrument's
function parameters, press the key P and keep it pressed for about
5 seconds, after which the SET led will light up, the display will
visualised the code that identifies the first group of parameters
]
("
SP ") and the group of parameters that are to be edited are
selected by pressing the UP and DOWN keys ("
Once the group of parameters has been selected, press the P and
the code that identifies the parameter in the selected group will be
visualised ( "SP1" into "
desired parameter has be selected, pressing the P key, the display
will alternately show the parameter code and its setting that can be
changed with the UP and DOWN keys. 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 abbreviation of the
selected parameter. To return to select another group of
parameters, keep the UP or the DOWN key pressed for about 1
second, after which the display will return to showing the code of
the parameter group. Release the pressed key and using the UP
and DOWN keys it will be possible to select another group . 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.
Hold for
5 sec.
3 - INFORMATION ON INSTALLATION AND USE
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
3
respected, also after the instrument installation, if necessary using
proper filters. Whenever a failure or a malfunction of the device
2
may cause dangerous situations for persons, thing or animals,
please remember that the plant has to be equipped with additional
1
devices which will guarantee safety.
6
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
