IC901
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 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, indicated 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 functions.
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 Diagram)
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 folders in the menu:
-AL: alarm folder (if present);
-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.
Alarm on
If alarm condition exists, when accessing
The “Machine Status” menu the “AL” folder label appears (see the “Diagnostics” section).
Displaying Probes
By pressing the “set” key when the appropriate label appears, the value of the
probe associated to it is displayed.
PROGRAMMING MENU
(See Programming Menu Diagram)
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; the folders
contain the level 1 and 2 parameters. The
level 2 parameters may be protected by a
second password (parameter “PA2”).
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 malfunctioning
on regulation and delay time occuring.
PASSWORD
The password “PA1”allow access to level 1
parameters. In the standard configuration
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 PA1
at the entrance of the
“Programming” menu;
COPY CARD
The Copy Card is an accessory connected
to the TTL serial port which allows programming quickly the instrument parameters. The operation is performed as follows:
Fr-Format
This command allows copy card formatting, an operation recommended in case
of first use.
Warning: if the copy card has been programmed, using the “Fr” the data entered
are erased. This operation cannot be cancelled.
UL-Upload
This operation loads the programming
parameters from the instrument.
dL-Download
This operation downloads to the instrument 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 confirmed by pressing the “set” key. If the
operation is successful an “y” is displayed,
on the contrary, if it fails a “n” will be displayed.
NOTE:
• UPLOAD: instrument --> Copy Card
• DOWNLOAD: Copy Card --> instrument.
KEYBOARD LOCKING
The instrument includes a facility for disabling 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
INSTALLATION
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.

WARNING!: In 15A version buzzer is not

MINIMUM AND MAXIMUM TEMPERATURE ALARMS
Regulation of the minimum and maximum
temperature alarms refers to the thermostat probe.
The temperature limits defined by the
“HAL” (maximum temperature alarm) and
“LAL” parameters (minimum temperature
alarm) are in absolute temperature value.
When an alarm status occurs, if no alarm
exclusion phases are underway (see alarm
exclusion parameters), the alarm set icon
is lit up and the buzzer, and/or the relay
configured as an alarm, is activated. The
occurrence of this alarm does not in anyway effect the control activities in
progress. This alarm status can be viewed
in the “AL” folder with AH1-AL1 labels.

If silenced it will blink.
Alarms are considered as absolute values.
IC 901 A
The instrument is designed for flush panel
mounting. Insert the unit through a
71x29 mm panel cut-out and affix with the
U-bracket supplied.
Select a location which will not be subject
to high humidity or condensation and
allow some ventilation to provide cooling
to the instrument.
ELECTRICAL
CONNECTIONS
Attention! Never work on electrical
connections when the machine is
switched on.
The instrument is equipped with screw terminal 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.
Relay outputs are voltage free. Do not
exceed the maximum permissible current
– in case of higher loads, use a contactor
of adequate power. Make sure that the
supplied voltage matches the values specified for the instrument.
In the versions supplied on 12V, the power
supply must be provided via a safety transformer protected by a 250 mA delayed
fuse. The probes do not have any insertion
polarity and can be lengthened by using a
normal bipolar cable (note that if the
probes are lengthened, this will affect the
behaviour of the instrument in terms of
EMC electro-magnetic compatibility –
wiring must be done with great care).
We advise you to keep the probe and supply cables well away from the power
cables.
CONDITIONS OF USE
PERMITTED USE
For safety reasons the instrument must be
installed and used according to the
instruction provided and in particular,
under normal conditions, parts bearing
dangerous voltage levels must not be
accessible.
The device must be adequately protected
from water and dust as per the application
and must also only be accessible via the
use of tools (with the exception of the
frontlet).
The device is ideally suited for use on
household appliances and/or similar refrigeration equipment and has been tested
with regard to the aspects concerning
European reference standards on safety. It
is classified as follows:
• according to its manufacture: as an automatic electronic control device to be
incorporated by independent mounting;
• according to its automatic operating features: as a 1 B-type operated control type;
• as a Class A device in relation to the category and structure of the software
UNPERMITTED USE
Any other use other than that permitted is
de facto prohibited. It should be noted
that the relay contacts provided are of a
practical type and therefore subject to
fault. Any protection devices required by
product standards or dictated by common
sense due to obvious safety reasons should
be applied externally.
