Variables display
The display normally shows the variable set at parameter
DS
,
but the user can view all the measurement and operating vari-
ables by simultaneously pressing the / and /
trb
keys
for about 5 seconds after wich the display alternately shows
the code that identifies the first viewable variable and its value.
Then with the / keys the user can see all the variables:
P1
Probe
Pr1
measurement;
P2
Probe
Pr2
measurement;
P3
Probe
Pr3
measurement;
lt
Minimum Pr1
stored temperature;
Ht
Maximum Pr1
stored temperature.
If the mains voltage alarm function is enabled (
LU
or
HU
other
than
oF
), this mode shows also the
P5
variable representing
the mains voltage value decreased by 150. The mains ex-
pressed in Volt measured by the instrument will therefore be:
V
=
P5 + 150
.
The temperature peak values
Lt
and
Ht
are not saved in
case of power failure and can be reset pressing for about 3 s
the / key while showing the peak values
Lt
/
Ht
.
After 3 seconds the display shows “
---
” for an instant to
indicate the deletion and takes as peak temperature the one
measured at that moment.
To exit the display variables mode, press no keys for about
10 s or press the / button.

3. USAGE WARNINGS
3.1
Admitted use
D
The instrument has been projected and manufactured
as a measuring and control device to be used accord-
ing to EN60730-1 at altitudes operation below 2000 m.
Using the instrument for applications not expressly permitted
by the above mentioned rule must adopt all the necessary
protective measures.
The instrument
MUST NOT BE USED
in dangerous environ-
ments (flammable or explosive) without adequate protections.
The instrument used with NTC 103AT11 probe (identifiable
by the printed code “103AT-11” visible on the sensor part)
is compliant with standard EN 13485 (“Thermometers for
measuring the air and product temperature for the transport,
storage and distribution of chilled, frozen, deep-frozen/quick-
frozen food and ice cream”) with the following classification:
[EN13485 air, S, A, 2, -50°C +90°C].
Remember that the end user must periodically check and veri-
fy the thermometers in compliance with standard EN 13486.
The installer must ensure that the EMC rules are respected,
also after the instrument installation, if necessary using
proper filters.
4. INSTALLATION WARNINGS
4.1
Mechanical mounting [mm]
The B05B Control Unit, is designed for panel mounting using
2 screws.
The P03 display panel in case 96 x 50 mm, is designed for
flushing panel mounting. Make a 90 x 44 mm hole and insert
the panel, fixing it with the provided special brackets. We
recommend that the gasket of the panel is mounted in order
to obtain the protection degree as declared.
The P34 display panel in case 78 x 35 mm, is designed for
flushing panel mounting. Make a 71 x 29 mm hole and in-
sert the panel, fixing it with the provided special brackets. To
obtain the declared protection degree, mount the P34 panel
using the screw type bracket (optional).
Avoid placing the instrument in environments with very high
levels of humidity that may create condensation or dirt that
could lead to the introduction of conductive parts or sub-
stances into the instruments.
Ensure adequate ventilation to the instrument and avoid
installation in containers that house devices which may
overheat or which may cause the instrument to function at a
higher temperature than the one permitted and declared.
Connect the instrument as far away as possible from sources
of electromagnetic disturbances such as motors, power re-
lays, relays, solenoid valves, etc..
