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 with the "UP"
and "DOWN" keys, and confirm with the
"SET" key, to move to the next parameter.
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 that con-
nected to the serial door TTL permits both
fast programming of instrument's parame-
ters (download), and the possibility to save
the instrument's parameters (upload) in
order to use them to ri-program other
equivalent instruments. To do this opera-
tion enter the folder identified from
label "FPr" and use parameters "UL" or
"dL" depending on the case; to start
uploading (downloading) simply press
"SET" button.
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
room probe (probe 1) is shown as E1 on
the instrument display 1.
Status
ON for compressor ON, flashing for delay, disabled protection
or activation
ON for current defrosting; flashing for manual activation
ON for an active alarm
INSTALLATION
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 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 mm
conductor only per terminal for power
connections). For the capacity of the ter-
minals, 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 speci-
fied for the instrument.
In the versions supplied on 12V, the power
supply must be provided via a safety trans-
former 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 sup-
ply 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 refrig-
eration equipment and has been tested
with regard to the aspects concerning
