/4 0 1 --- 0 leading zeroes displaying
It establishes if to display the leading zeroes, as indicated:
0 = the leading zeroes get not displayed
1 = the leading zeroes get displayed.
/5 0 1 --- 1 decimal point
It establishes the resolution with which the temperature gets displayed, as indicated:
0 = the temperature gets displayed with the resolution of the unit of measure
1 = the temperature gets displayed with the resolution of 1/10 of the unit of measure.
/6 -99 +999 points -20 lower end of scale for 0/4-20 mA input (it coincides with
the minimum calibration value of the transducer)
It establishes the lower end of scale for 0/4-20 mA input and it must coincide with the mini-
mum calibration value of the transducer.
/7
-99 +999 points +80 upper end of scale for 0/4-20 mA input (it coincides with
the maximum calibration value of the transducer)
It establishes the upper end of scale for 0/4-20 mA input and it must coincide with the maxi-
mum calibration value of the transducer.

PROTOCOL COMMUNICATION
L1 1 15 --- 1 instrument address
It establishes the address to which the instrument (slave) answers when it is connected to a
serial network with EVCOBUS protocol communication managed from a master (for instance a
Personal Computer).
L2
0 7 --- 0 instrument group
It establishes the group to which the instrument (slave) answers when it is connected to a
serial network with EVCOBUS protocol communication managed from a master (for instance a
Personal Computer).
ADDITIONAL INFORMATIONS
-
the symbol (*) indicates that the value depends from the measure input presetting
requested
- if the instrument is preset to accept at the measure input “J”/”K” thermocouples
the parameter /5 does not exist
- if the instrument is not preset to accept at the measure input 2 and 3 wires 0/4-20
mA temperature transducers the parameters /6 and /7 do not exist.
ALARMS
ALARMS
If the instrument displays the indication “E2” flashing (corrupted memory data alarm) it means
that there is a corruption of the configuration data in the memory (turn OFF and turn ON again
the instrument: if to the turning ON again the alarm does not disappear the instrument must be
replaced); during this alarm the access to the configuration parameters setting procedure is
refused.
If the instrument displays the indication “E0” flashing (probe failure alarm) it means that: the
kind of connected probe is not proper (see the parameter /0), the probe is faulty (verify the
probe integrity), there is a mistake in the instrument-probe connection (verify the instrument-
probe connection integrity), the temperature read by the probe is outside the limits permitted
by the probe in use (verify that the temperature near the probe be inside the limits permitted by
the probe); inactive.
If the instrument displays the indication “E0C” flashing (cold junction/third wire failure alarm)
it means that, if the instrument is preset to accept at the measure input “J”/”K” thermocouples
there is a mistake in the cold junction adjustment circuit (the instrument must be replaced), if
the instrument is preset to accept at the measure input 2/3 wires Pt 100 probes and it is set to
recognize to its measure input 3 wires Pt 100 probes the third wire of the probe is not con-
nected (verify the instrument-probe connection integrity); inactive.
If the instrument displays the indication “999” flashing (end of scale display) it means that the
temperature read by the probe is outside the working range permitted by the instrument (verify
that the temperature near the probe be inside the limits permitted by the instrument); inactive.
