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

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

1) Level 1 P

arameters

To access the “Programming” menu, press
the “set” key for more than 5 seconds. If
specified, the level 1 access PASSWORD
will be requested (see parameter “PA1”)
and (if the password is correct) the label
of the first folder will follow. If the pass­word is wrong, the display will show the
PA1 label again.

To scroll other folders, use the “UP” and
“DOWN” keys; the folders contain only

the level 1 parameters.
NOTE: At this point level 2 parameters
are NOT visible, even if they aren’t
protected by password.

2) Level 2 P

arameters

In the Programming Menu go into the
“CnF” folder, scroll all the parameter until
you reach the PA2 label. By pressing and
releasing the “set” button you will enter to
level 2 parameters and the label of the
first folder in the programming menu will
follow.
The level 2 parameters may be protected
by a second password (see “PA2” parame­ter inside “diS” folder, not to be confused
with PA2 label inside “CnF” folder.
If specified, level 2 parameters are hidden
to user; accessing the “CnF” folder the
level 2 access PASSWORD will be request­ed and (if the correct password is entered)
the label of the first folder in the pro­gramming menu will follow.

NOTE: At this point you will see only
level 2 parameters.

Level 1 parameters will NOT be visible;
to reach them you shall exit the
Programming Menu and re-entry the
Programming Menu section (see step 1).
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. Move to the next parameter.
PLEASE NOTE: It is suggested to switch­off 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 passwords “PA1” and “PA2” allow
access respectively to level 1 and level 2
parameters. In the standard configuration
passwords are not present. To enable
them (value 0) and assign them the
desired value, access the “Programming”
menu, within the folder with the “diS”
label. If passwords are enabled, they will
be requested:

- PA1 at the entrance of the
“Programming” menu (see the
“Programming Menu“ section);

- PA2 within the folder with the “Cnf”
label containing level 1 parameters.

MANUAL ACTIVATION OF THE
DEFROSTING CYCLE

To manually activate the defrosting cycle,
press the “UP” key for 5 seconds.
If defrosting conditions are not present,
(for example the evaporator probe
temperature is higher than defrost stop
temperature), the display
will blink three (3) times, in order to
indicate that the operation will not
be performed.

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:

FrFormat

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.

NOTE:

• UPLOAD: instrument --> Copy Card

• DOWNLOAD: Copy Card --> instru­ment.

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.

TELEVIS SYSTEM

The link with the Televis system can go
through the serial port TTL (the BUS
ADAPTER 100 TTL RS-485 interface module
must be used).
In order to configure the instrument for
this purpose you must access the folder
identified by the “Add” label and use the
parameters “dEA” and “FAA”.

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

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 (referred to probe 1)
is shown as E1 on the instrument display

When the sensor detects an error condi­tion:

• the code E1 is displayed

• the compressor is activated as indicated
by the "On" and "Off" parameters if pro­grammed for the duty cycle or:

Other signalling alarm are not shown on
the instrument display, but from the
“Machine Status” menu within the “AL”
folder.

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.

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 ter­minal boards for connection of electrical
cables with a diameter of 2.5 mm

2

(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.
