1.3 MOUNTING REQUIREMENTS
This instrument is intended for permanent installation, for
indoor use only, in an electrical panel which encloses the
rear housing, exposed terminals and wiring on the back.
Select a mounting location having 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 fl uids (i.e. condensation);
5. The ambient temperature is in accordance with the
operative temperature (0 to 50°C);
6. The relative humidity is in accordance with the instrument
specifi cations (20 to 90%);
The instrument can be mounted on panel with a maximum
thickness of 8 mm.
When the maximum front protection (IP65) is
desired, the optional gasket must be mounted.
This is mandatory for FM approval.

devices with one remote master unit.
9600 baud.
2.5 POWER SUPPLY
Supply Voltage: 100 to 240 VAC (-15 to +10%).
Notes: 1. Before connecting the instrument to the power
line, make sure that line voltage is equal to the
voltage shown on the identifi cation label;
2. The polarity of the power supply has no importance;
3. The power supply input is NOT fuse protected.
Please, provide a T type 1A, 250 V fuse externally.
When the instrument is powered, it starts immediately
to work according to the parameters values loaded in its
memory.
The instrument behaviour and its performance are governed
by the value of the stored parameters.
At the fi rst start up the instrument will use a “default” parameter set (factory parameter set); this set is a generic one
(e.g. a TC J input is programmed).
WARNING! Before connecting the output actuators, we
recommend to confi gure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).
To change these parameters you need to enter the “Confi guration mode”.
5.2 INSTRUMENT BEHAVIOUR AT POWER
ON
At power ON the instrument can operate in two different
mode according to the value assigned to [34] r.md parameter [34] r.md equal to 0
(Limit output is de-energized at power on in any cases.)
The output relay is always de-energized (opened) at poweron,even if PV does not exceed SP(A). The output (OUT)
display lamp is lit. If thePV does not exceed SP, after the
confi rming operation, output relay will be energized (closed)
and the output (OUT) display lamp turns off .
5.3 HOW TO ENTER THE
“CONFIGURATION MODES”
The confi guration procedure allows to take advantage of all
instrument features.
The instrument have one complete parameter set.
We call this set “confi guration parameter set” (or
“confi guration parameters”).
The access to the confi guration parameters is
password.
5.3.1 Complete confi guration procedure
The confi guration parameters are collected in various
groups. Every group defi nes all parameters related with a
specifi c function (e.g.: control, alarms, output functions).
1. Push the button for more than 3 seconds. The upper
display will show PASS while the lower display will show 0.
2. Using and buttons set the programmed password.
Notes: 1. The factory default password for confi guration
parameters is equal to 30.
3. Push the button
If the password is correct the display will show the acronym
protected by a
[34] r.md equal to 1(Limit output is de-energized at power on
in any cases.)The state of output relay is energized (closed)
and the output (OUT) display lamp turns off if the PV does
not exceed SP at power-on.
of the fi rst parameter group preceded by the symbol:
In other words the upper display will show:

(group of the Input parameters).
The instrument is in confi guration mode.
5.4 HOW TO EXIT THE “CONFIGURATION
MODE”
Push button for more than 3 seconds, the instrument will
come back to the “standard display”.
5.5 KEYBOARD FUNCTIONS DURING
PARAMETER CHANGING
A short press allows to exit from the current parameter
group and select a new parameter group.
A long press allows you to close the confi guration
parameter procedure (the instrument will come back
to the “standard display”).
When the upper display is showing a group and the
lower display is blank, this key allows to enter in the
selected group.
the lower display is showing its value, this key allows
to store the selected value for the current parameter
and access the next parameter within the same group.
Allows to increase the value of the selected parameter.
Allows to decrease the value of the selected parameter.
+ These two keys allow to return to the previous
group. Proceed as follows:
Push the button and maintaining the pressure,
then push the button; release both the buttons.
Note: The group selection is cyclic as well as the selection
Sometime, e.g. when you re-confi gure an instrument
previously used for other works or from other people or when
you have made too many errors during confi guration and
you decided to re-confi gure the instrument, it is possible to
restore the factory confi guration.
This action allows to put the instrument in a defi ned
condition (the same it was at the fi rst power ON).
The default data are those typical values loaded in the
instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1. Press the
display will show PASS while the lower display shows 0;
2. Using
3. Push
4. The instrument will turn OFF all LEDs for a few seconds,
then the upper display will show dFLt (default) and then
all LEDs are turned ON for 2 seconds. At this point the
instrument restarts as for a new power ON.
The procedure is complete.
Note: The complete list of the default parameters is available
in Appendix A.

5.7 CONFIGURING ALL THE PARAMETERS
In the following pages we will describe all the parameters of
the instrument. However, the instrument will only show the
parameters applicable to its hardware options in accordance
with the specifi c instrument confi guration (i.e. setting AL1t
[Alarm 1 type] to nonE [not used], all parameters related to
alarm 1 will be skipped).
