“CnF” menu, if, on the other hand, it is lit, the parameter can
also be programmed in the “OPr” menu.
Press the ON/OFF key to modify the visibility of the parameter:
the SET1 led will change status, thus indicating the
parameter’s level of accessibility (on = “OPr” and “CnF”; off =
“CnF” menu only).
3 - INFORMATION ON INSTALLATION AND USE
3.1 - PERMITTED USE
The instrument has been projected and
manufactured as a measuring and control
device to be used according to EN61010-1
The use of the instrument for applications not
expressly permitted by the above mentioned rule must adopt
all the necessary protective measures.
The instrument CANNOT be used in dangerous environments
(flammable or explosive) without adequate protection.
The installer must ensure that EMC rules are respected, also
after the instrument installation, if necessary using proper
filters.
Whenever a failure or a malfunction of the device may cause
dangerous situations for persons, thing or animals, please
remember that the plant has to be equipped with additional
devices which will guarantee safety.

3.2 – MECHANICAL MOUNTING
The instrument, in case DIN 72 x 144 mm, is designed for
flush-in panel mounting.
Make a hole 139 x 68 mm mm 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 introduction of conductive
substances into the instrument.
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 relays,
relays, solenoid valves, etc.
3.3 - ELECTRICAL CONNECTION
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
instrument and that the load current absorption is no higher
than the maximum electricity current permitted.
As the instrument is built-in equipment with permanent
connection inside housing, it is not equipped with either
switches or internal devices to protect against overload of
current: the installation will include 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 all the electrical circuits connected
to the instrument must be protect properly, using devices (ex.
fuses) proportionate to the circulating currents.
It is strongly recommended that cables with proper insulation,
according 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 with only one
side.
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.
OSAKA. and its legal representatives do not assume any
responsibility for any damage to people, things or animals
deriving from violation, wrong or improper use or in any
case not in compliance with the instrument’s features.

4 - FUNCTIONS
4.1 - MEASURING AND VISUALIZATION
All the measurement parameters are contained in the
“
]
In”
group.
The instrument has a maximum of 4 temperature probe inputs:
1 (t) – TOP probe
2 (F) – FLOOR probe
3 (S) – STEAM probe
(Optional)
4 (A) – Auxiliary AUX probe (AUX)
(Optional)
If the model in question has inputs for thermocouples by
means of the
“SEn”
parameter, it is possible to select the type
of probe to use, which can be for thermocouples J (J) or K
(CrA).
The unit of temperature measurement is established by the
“uni”
parameter and can be set to either °C or °F.
It should be noted that when this parameter is changed, it only
changes the display, not the Set Point and the parameters,
which must be modified manually (for example if the Set Point
was 50°C and the unit of measurement is changed, the set
point will change to 50°F).
The
“OSt”, “OSF”, “OSS”, “OSA”
parameters can be used to
set a positive or negative offset that is added to the value read
by the relative probe before displaying, to which the regulation
function is also connected. The displays normally show the
temperatures measured by the other probes (if present and
enabled with the
“EFP”, “ESP”, “EAP”
parameters) by
pressing and releasing the SEL IN (DOWN) key.
The upper display will alternately show
“SP”
and the
temperature measured by the steamer probe, by pressing the
SEL IN key again within 5 seconds, the display will show
“AP”
and the temperature measured by the AUX probe.
After 5 seconds of inactivity, the display will return to its normal
function.
