to be installed must be between 0.8 and
2.0 mm (0.031 and 0.078 in)
-
make sure that the device work conditions (tempera-
ture of use, humidity, etc.) lie within the limits indi-
cated; see chapter 13
-
do not install the device near to any heat sources (heating
elements, hot air ducts etc.), equipment containing
powerful magnets (large diffusers, etc.), areas affected
by direct sunlight, rain, humidity, excessive dust, me-
chanical vibrations or shocks.
-
any metal parts in proximity of the control module must
be at a distance such that they do not compromise the
safety distances.

device terminal board
-
if the device has been taken from a cold to hot place,
humidity could condense inside; wait about 1 hour be-
fore powering it
-
make sure that the power supply voltage, the fre-
quency and the operational electric power of the de-
vice, correspond with those of the local power supply;
see chapter 13

USER INTERFACE
3.1
Preliminary notes
Operating Statuses:
-
“on” state (the device is powered and is on: the regu-
lators can be switched on)
-
“stand-by” status (the device is powered but is switched
off via software: the regulators are switched off; the
possibility to manually switch on/switch off the cabinet
light or auxiliary output depends on parameter u2)
-
the “off” status (the device is not powered).
Hereafter, with the word “start-up” means the passage from
“stand-by” status to “on” status; the word “shutdown” means
the passage from “on” status to “stand-by” status.
When the power is switched back on, the device displays the
status that it was in at the time it was disconnected.
3.2
Device switch-on/off in manual mode
Operating Statuses:
1.
Make sure that the keyboard is not locked and that no
procedure is in progress.
2.
Hold the
key down for 2 s: the LED will switch
off/on.
Using the digital inputs it is also possible to remotely switch
on/off the device.
3.3
The display
If the device is switched on, during normal operation, the
display will show the magnitude established with P5, except
during defrosting, when the device will show the tempera-
ture established with parameter d6.
If the device is switched off, the display will be switched off.
3.4
Cabinet temperature display (if parameter P4
is set at 0, 1 or 2) or the temperature de-
tected by the inlet air probe (if parameter P4
is set at 3)
1.
Make sure that the keyboard is not locked and that no
procedure is in progress.
2.
Hold the
key down for 1 s: the display will show the
first label available.
