Displaying the alarms (if present)
At start-up the instrument performs a
Lamp Test; for few seconds the display and
the leds blink, in order to verify their
integrity and correct operation. The instru-
ment 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
(See Machine Status Menu)
To access the “Machine Status” menu
Press and quickly release the “set” key.
If alarms are not present, the label “SEt”
appears. By using the “UP” and “DOWN”
keys you can scroll through the other fold-
ers in the menu:
-Pb1: probe 1 value folder;
-SEt: Setpoint setting folder.
Set Setting
Access the “Machine Status” menu by
pressing and quickly releasing the “set”
key. The label of the “Set” 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.
Displaying Probes
By pressing the “set” key when the appro-
priate label appears, the value of the
probe associated to it is displayed.
PROGRAMMING MENU
(See 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 (if the
password is correct) the label of the first
folder will follow.
To scroll through the other folders, use
the “UP” and “DOWN” keys.
If the password is wrong, the display will
show the PA1 label again.
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 suggested to switch-
off and switch-on again the instrument
everytime it is changed the configuration
of the parameters: this prevents malfunc-
tioning on regulation and delay time
occuring.
PASSWORD
The password “PA1” allows access to pro-
gramming parameters. In the standard
configuration password is not present.
To enable (value≠0) and assign it the
desired value, access the “Programming”
menu, within the folder with the “diS”
label. If password is enabled, you will see
it at the entrance of the “Programming”
menu (see the “Programming Menu“ sec-
tion).
MANUAL ACTIVATION OF THE
DEFROSTING CYCLE
To manually activate the defrosting cycle,
press the “UP” key for 5 seconds.
COPY CARD
The Copy Card is an accessory connected
to the TTL serial port which allows pro-
gramming quickly the instrument parame-
ters. The operation is performed as fol-
lows:
Format
This command allows copy card format-
ting, an operation recommended in case
of first use.
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.
NOTE:
• UPLOAD: instrument --> Copy Card
• DOWNLOAD: Copy Card --> instru-
ment.

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 buzzer (if present) and by the led of
the alarm icon
The alarm signal produced by a faulty
thermostat probe (probe 1) is shown as E1
on the instrument display.
When the sensor detects an error condi-
tion:
• the code E1 is displayed
• the compressor is activated as indicated
by the "On" and "Off" parameters if pro-
grammed for the duty cycle or:
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
connections 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.
Probes have no connection polarity and
can be extended using a regular bipolar
cable (note that the extension of the
probes affects the EMC electromagnetic
compatibility of the instrument: pay
extreme attention to wiring).
Probe cables, power supply cables and the
TTL serial cables should be distant from
power cables.
