items
Increases the values
DOWN key Scrolls through the menu items
Decreases the values
fnc key ESC function (exit)
set key Accesses the setpoint
Accesses the menus
Confirms the commands
Displays the alarms (if active)
At start-up the instrument performs a
Lamp Test; for five (5) seconds the display
and the leds blink, in order to verify their
integrity and correct operation; afterwards
it will appear the label “Lod” (Loading) for
ten (10) seconds. The instrument has two
main menus: the “Machine Status” and
“Programming” menu.
ACCESSING AND USING MENUS
Resources are arranged in a menu, which
can be accessed by pressing and quickly
releasing the “set” key (“Machine Status”
menu) or by holding down the “set” key
for more than 5 seconds (“Programming”
menu).
To access the contents of each folder, indi-
cated by the relevant label, just press the
“set” key once.
You can now scroll through the contents
of each folder, modify it or use its func-
tions. If you do not use the keyboard for
over 15 seconds (time-out) or if you press
the “fnc” key once, the last value shown
on the display is confirmed and you return
to the previous screen mask.
MACHINE STATUS MENU
To access the “Machine Status” menu
Press and quickly release the “set” key.
The label “SP1” appears.
By using the “UP” and “DOWN” keys you
can scroll through the other folders in the
menu:
-AL: alarm folder (if alarms present);
-SP1: Setpoint 1 setting folder.
Setpoint Setting
Access the “Machine Status” menu by
pressing and quickly releasing the “set”
key. The label of the “SP1” folder appears.
To display the Setpoint value press the
“set” key again.
The value appears on the display.
To change the Setpoint value, use the “UP”
and “DOWN” keys within 15 seconds.
If the parameter is LOC = y the Setpoint
cannot be changed.
PROGRAMMING MENU
To enter the “Programming” menu, press
the “set” key for more than 5 seconds.
If specified, the access PASSWORD will be
requested, (parameter “PA1”), and the
label of the first folder will follow.
To scroll through the other folders, use
the “UP” and “DOWN” keys.
To enter the folder, press “set”. The label
of the first visible parameter appears. To
scroll through the other parameters, use
the “UP” and “DOWN” keys; to change the
parameter, press and release “set”, then
set the desired value using the “UP” and
“DOWN” keys, and confirm with the “set”
key to move to the next parameter.
PLEASE NOTE: It is strongly recommended
to switch off and switch on again the con-
troller anytime parameters have been
changed to prevent malfunctioning on
configuration and/or ongoing timings.
PASSWORD
The password “PA1” allows access to level
1 parameters. In the standard configura-
tion passwords are not present.
To enable them and assign them the
desired value, access the “Programming”
menu, within the folder with the “diS”
label. If passwords are enabled, you will
see it at the entrance of the “Program-
ming” menu.
COPY CARD
The Copy Card is an accessory connected
to the TTL serial port which allows pro-
gramming quickly the instrument parame-
ters (upload and download parameter’s
map). The operation is performed as fol-
lows:
Format
This command allows copy card formatting,
an operation necessary in case of first use
or to copy maps with different models.
Warning: if the copy card has been pro-
grammed, using the “Fr” the data entered
are erased. This operation cannot be can-
celled.
Upload
This operation loads the programming
parameters from the instrument.
Download
This operation downloads to the instru-
ment the programming parameters.
The operations are performed accessing
the folder identified by the “FPr” label and
selecting, according to the case, “UL”, “dL”
or “Fr” commands; the operation is con-
firmed by pressing the “set” key. If the
operation is successful an “y” is displayed,
on the contrary, if it fails a “n” will be dis-
played.
Download “from reset (instrumennt
OFF”
Connect the Copy Card with the instru-
ment OFF (not under voltage).
When the instrument is switched on the
programming parameters will be down-
loaded into the instrument (this operation
takes about 15 seconds); after the lamp-
test the diplay will show for about 5 sec-
onds:
• label dLY if copy operation successful
• label DLn if not
PLEASE NOTE:
• after the download operation the instru-
ment will immediately work with the new
parameters map setting
KEYBOARD LOCKING
The instrument includes a facility for dis-
abling the keyboard, by programming the
“LOC” parameter (see folder with “diS”
label). If the keyboard is locked, you can
still access the programming menu by
pressing the “set” key.
The Setpoint can also be viewed.

DIAGNOSTICS
The alarm condition is always signalled by
the led of the alarm icon
The alarm signal (referred to the analogue
input) is shown as E1 on the instrument
display for a faulty analogue input error or
for reading values outside the viewing
range.
When the analogue input detects an error
condition:
• the code E1 is displayed
• the regulator is activated as indicated by
the "On1" and "OF1" parameters if pro-
grammed for the duty cycle or:
PLEASE NOTE: In case of wrong connec-
tion of the 3rd wire (Pt100 sensor) in “AL”
folder it will appear the label “Pt3”.
For few seconds the display will shows
a uncorrect temperature.
INSTALLATION
The instrument is designed for panel
mounting. Make a hole of 29x71 mm,
insert the instrument and fix it using the
brackets provided. Do not mount the
instrument in humid and/or dirty places; it
is suitable for use in ordinary polluted
places. Ventilate the place in proximity to
the instrument colling slits.
ELECTRICAL
WIRING
Attention! Never work on electrical con-
nections when the machine is switched on.
The instrument is equipped with screw ter-
minal boards for connection of electrical
cables with a diameter of 2.5 mm2(one
conductor only per terminal for power
connections).
For the capacity of the terminals, see the
label on the instrument.
The relay contacts are voltage free. Do not
exceed the maximum current allowed; in
case of higher loads, use an appropriate
contactor. Make sure the power supply
voltage complies with the one required by
the instrument.
In 12V versions the power supply must be
provided by a security transformer with
the protection of a delayed 250 mA fuse.
Probe cable (Pt100 model), power supply
cables and the TTL serial cables should be
distant from power cables.
(Pt100 model)
Probe can be extended using a regular
bipolar cable (note that the extension of
the probes affects the EMC electromagnet-
ic compatibility of the instrument: pay
extreme attention to wiring).
