Manuale XE inglese
Thank you for choosing an ASCON controller
The instruments of the XE series belong to the last generation of
microprocessor based controller, are universal, very powerful but
simple to use.
They are fitted with A TO-T NE, as aid for system start-up, and serial
communication for introduction into a distributed control network.
They are complete because all possible variables are always present.
Configuration of the instrument permits determination of the operating
mode according to the application required.

with a 15 m. probe to controller distance
and a 1.5 sq.mm. section cable, the error
is about 1°C.
