Thank you for choosing an ASCON controller
The instruments of the XS series belong to the last generation of
microprocessor based controller, are universal, very po erful but
simple to use.
They are fitted ith AUTO-TUNE and EXPERT-TUNE, an auxiliary for
system start-up, and serial communication for introduction into a
distributed control net ork.
They are complete because all possible variables are al ays present.
Configuration of the instrument permits determination of the operating
mode according to the application required.

Any interruption in the connections
or any anomaly in the operation of
one of the control loop components
will cause the output Y3 to be
energized after a few minutes and
front display X and W will be
flashing.
The alarm state will stop when the
anomaly causing it stops or
depressing any key for silencing it.
Only available with the Programmable Set point option.
The ON or OFF state of the auxiliary outputs Y2 and/or Y3 can be
