In case of failure or malfunction of measuring and control
equipment that can create dangerous situations or damage to
persons, things, animals or products (defrost food or changes in
their ideal state), it is recalled that the facility should be equipped
with electronic devices or electromechanical safety and warning
system.
They should be placed outside the measuring and control
equipments, possible protective devices, responding to specific
safety requirements that are covered by the norm of the product
or suggest the common sense.
For your own safety, is highly recommended fulfilling the
instructions provided above.
The instrument used with NTC-1 (2)-IP68 probe (identifiable by the
printed code “NTC-1 (2)-IP68” 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 verify
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
The instrument, in case 78 x 35 mm, is designed for flush-in panel
mounting. Make a 71 x 29 mm hole and insert the instrument,
fixing it with the provided special brackets.
We recommend that the gasket is mounted in order to obtain the
front protection degree as declared.
Avoid placing the instrument in environments with very high
humidity levels or dirt that may create condensation or introduc-
tion of conductive substances into the instrument
Ensure adequate ventilation to the instrument and avoid instal-
lation in containers that house devices which may overheat or
which may cause the instrument to function at a higher tem-
perature than the one permitted and declared.
Connect the instrument as far away as possible from sources
of electromagnetic disturbances such as motors, power relays,
relays, solenoid valves, etc..

4.2 Electrical
connections
Carry out the electrical wiring by connecting only one wire to
each terminal, according to the following diagram, checking that
the power supply is the same as that indicated on the instru-
ment and that the load current absorption is no higher than the
maximum electricity current permitted.
As the instrument is built-in equipment with permanent con-
nection inside housing, it is not equipped with either switches
or internal devices to protect against current overloads: the
installation will include an overload protection and a two-phase
circuit-breaker, placed as near as possible to the instrument and
located in a position that can easily be reached by the user and
marked as instrument disconnecting device which interrupts the
power supply to the equipment
It is also recommended that the supply of all the electrical circuits
connected to the instrument must be protect properly, using de-
vices (ex. fuses) proportionate to the circulating currents.
It is strongly recommended that cables with proper insulation, ac-
cording to the working voltages and temperatures, be used.
Furthermore, the input cable of the probe has to be kept separate
from line voltage wiring. If the input cable of the probe is screened,
it has to be connected to the ground at only one side.
j
We recommend that a check should be made that the
parameters are those desired and that the application
functions correctly
before connecting the outputs to the
actuators
so as to avoid malfunctioning that may cause
irregularities in the plant that could cause damage to
people, things or animals.
