To gain access to the second level enter inside the first level and select the label PA.
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 -19 (keeping

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 C0, C1, C2 and C4).

ALARMS
If the instrument displays the indication E2 flashing and the buzzer utters an intermittent

beep (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 and the buzzer utters an intermittent

beep (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 instru-

ment-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 tempera-

ture 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 C3.
If the instrument displays the temperature read by the probe flashing and the buzzer utters an

intermittent beep (temperature alarm) it means that the temperature read by the probe is

outside the limit established with the parameter A1 or A2 (see the parameters A0, A1 and A2);

inactive.
If the instrument displays the indication 99 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.
