2.5 Mounting requirements

This instrument is intended for permanent installa-
tion, for indoor use only, in an electrical panel which
encloses the rear housing, exposed terminals and
wiring on the back. Select a mounting location hav-
ing the following characteristics:
1. It should be easily accessible;
2. There is minimum vibrations and no impact;
3. There are no corrosive gases;
4. There are no water or other fluid (i.e.
condensation);
5. The ambient temperature is in accordance with
the operative temperature (0... 50 °C)
6. The relative humidity is in accordance with the
instrument specifications (20... 85 %)
The instrument can be mounted on panel with a
maximum thick of 15 mm. When the maximum front
protection (IP65) is desired, the optional gasket
must be monted.
2.6 Genereal notes about wiring
1. Do not run input wires together with power cables;
2. External components (like zener barriers, etc.)
connected between sensor and input terminals
may cause errors in measurement due to
excessive and/or not balanced line resistance or
possible leakage currents;
3. When a shielded cable is used, it should be
connected at one point only;
4. Pay attention to the line resistance; a high line
resistance may cause measurement errors.
5. Before connecting the instrument to the power
line, make sure that line voltage is equal to the
Bracket
voltage shown on the identification label.
type 2
6. The power supply input is NOT fuse protected.
Please, provide a T type 1A, 250 V fuse externally.
Notes:Safety precautions.
a) To avoid electrical shock, connect power at last;
b) For supply connections use No. 16 AWG or lar-
ger wires rated for at last 75°C;
c) Use copper conductors only;
d) Before connecting the instrument to the power
line, make sure that line voltage is equal to the
voltage shown on the identification label.
e) The power supply input is NOT fuse protected.
Please, provide a T type 1A, 250 V fuse exter-
nally.

3 - CONFIGURATION PROCEDURE

3.1 How to enter the configuration mode

1. Push the button for more than 3 seconds.
The display will show alternately 0 and PASS;
2. Using and/or buttons set the
programmed password.
Notes:
a) The factory default password for configuration
parameters is 30.
b) The parameter changes are protected by a time
out. If no key is pressed for more than 10 sec-
onds the instrument automatically returns back
to the Standard display, the new value of the last
selected parameter will be lost and the parame-
ter modification procedure closed.
Sometimes can be useful to enter the parameter
configuration procedure with no timeout (e.g. for
the first time an instrument is configured). In
this case, use a password equal to the previ-
ously set password + 1000 digits (e.g. 1000 + 30
TC/mV
[default] = 1030).
Pt100
It is always possible to manually end the
PTC-NTC
parameter configuration procedure (see the
next paragraph).
c) During parameter modification the instrument
continues to perform the Alarms and timer func-
tions. In certain conditions, when a configura-
tion change can produce a bump to the process,
it is advisable to temporarily stop the alarm
functions during the programming procedure (its
alarms output will be Off).
A password equal to 2000 + the programmed
value (e.g. 2000 + 30 = 2030).
The alarms will restart automatically when the
configuration procedure will be manually closed
3. Push the button
If the password is correct the display will show
OUT1
the acronym of the first parameter group
preceded by the symbol .
In other words the display will show
The instrument is in configuration mode.

3.2 How to exit the configuration mode

Push button for more than 5 seconds. The instru-
ment will come back to the "standard display".
3.3 Keyboard functions during
parameters modification
A short pression allows to exit the current param-
Ext.
eter group and select a new parameter group.
gen.
A long pression allows to close the configura-
tion parameter procedure (the instrument re-
turns to the "standard display").
PTC-NTC
Pt100
When the display is showing a group, the key
GND
TC
allows to enter in the selected group.
When the display is showing a parameter, the
key allows you to store the value shown and go

to the next parameter within the same group.
Increases the value of the selected parameter.
Decreases the value of the selected parameter.
OUT2
Note: The group selection is cyclic as well as the
selection of the parameters in a group.
3.4 Factory reset - Default parameters
loading procedure
Sometimes, e.g. when you reconfigure an instrument
previously used for other works or from other people
or when you have made too many errors during con-
figuration and you decided to reconfigure the instru-
ment, it is possible to restore the factory configuration.
This action allows you to put the instrument in a de-
fined condition (in the same condition it was at the
first Power ON).
The default data are the typical values loaded in the
instrument prior to shipping from factory. To load the
factory default parameter set, proceed as follows:
1. Press the button for more than 5 seconds;
2. The display will show alternately "PASS" and "0";
3. Using and
4. Push button;
5. The instrument will turn OFF all LEDs then it will
show "dFLt" messages and than it turn ON all
LEDs of the display for 2 seconds and than it will
restart as at the first power ON.
The procedure is complete (the default value of
each parameter is listed in the "Parameters Ta-
bles" paragraph).

4 - ERROR MESSAGES

4.1 Out of Range Signals

The display shows the OVER-RANGE and UNDER-
RANGE conditions with the following indications:
Over-range
The sensor break will be signalled as an out of range:
Note: When an over-range or an under-range is
detected, the alarms operate as in presence of
the maximum or the minimum measurable
value respectively.
WARNING!
Whenever a failure or a malfunction of the device may cause dangerous situations for persons,
things or animals, please remember that the plant must be equipped with additional safety de-
vices which will guarantee safety.
