pushed the key T1 or T2 the value gets decreased or increased more quickly): after the modi-
fication release the key T3 last (to the release of the key T3 the instrument displays the label PA
again); keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the first parameter of the second level).
To select a parameter of the second level push and release over and over the key T1 or T2 as
long as the instrument displays the label of the desired parameter.
To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets de-
creased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To turn out from the configuration parameters setting procedure keep pushed at the same time
for four seconds at least the keys T1 and T2 or do not operate with the keys for fifty seconds
at least (time-out exit).
ADDITIONAL INFORMATIONS
-
for the whole period of a corrupted memory data alarm the access to the configura-
tion parameters setting procedure is refused
-
the modification of a parameter value which unit of measure is the hour or the
minute or the second has not immediate effect; to obtain this effect it must not be
executed during the course of the value
-
the configuration parameters values get stored in a non volatile memory even if a
lack of power supply happens.

SIGNALS AND ALARMS
SIGNALS
If the LED L1 is turned ON it means that the output K 1 is activated.
If the LED L1 flashes it means that a count of a disabling time to the output K 1 activation is
running (see the parameters CA0, CA1, CA2 and CA4).
If the instrument displays the indication
≡≡≡
≡≡≡
≡≡≡
≡≡≡
≡≡≡
it means that the working setpoint can not be
modified (see the parameters rA5).
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 working setpoint setting and the configuration
parameters setting procedures is refused and the output K 1 gets forced to the status OFF.
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); during this alarm the output K 1 gets forced to the status established with the
parameter CA3.
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); during this alarm the output K 1 gets
forced to the status established with the parameter CA3.
If the instrument displays the indication AL1 flashing alternated to the temperature read by
the probe (first temperature alarm) it means that the temperature read by the probe is outside
the limit established with the parameter AA1 (see the parameters AA0, AA1 and AA4); inactive.
If the instrument displays the indication AL2 flashing alternated to the temperature read by
the probe (second temperature alarm) it means that the temperature read by the probe is
outside the limit established with the parameter Ab1 (see the parameters Ab0, Ab1 and Ab4);
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.
