MECHANICAL ASSEMBLY
The instrument is designed for panel mounting. Make a hole of 29x71 mm, insert the instrument and fix it using the
brackets provided. Do not mount the instrument in humid and/or dirty places; it is suitable for use in ordinary polluted
places. Ventilate the place in proximity to the instrument colling slits.
ELECTRICAL WIRING
Attention! Never work on electrical connections when the machine is switched on.
The instrument is equipped with screw terminal boards for connection of electrical cables with a diameter of 2.5 mm
2
(one
conductor only per terminal for power connections). For the capacity of the terminals, see the label on the instrument. In the
model ID 974 with Switching power supply only one voltage free relay output is present, on all other models on the contrary all
relay outputs are voltage free. Do not exceed the maximum current allowed; in case of higher loads, use an appropriate contactor.
Make sure the power supply voltage complies with the one required by the instrument. In 12V versions the power supply must
be provided by a security transformer with the protection of a delayed 250 mA fuse. Probes have no connection polarity and can
be extended using a regular bipolar cable (note that the extension of the probes affects the EMC electromagnetic compatibility
of the instrument: pay extreme attention to wiring). Probe cables, power supply cables and the TTL serial cables should be distant
from power cables.

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 using the “UP” and
“DOWN” keys, and confirm with the “set”
key to move to the next parameter.
PASSWORD
The password allows access to programming parameters. In the standard configuration password is not present.
To enable and assign it the desired value,
access the “Programming” menu, within
the folder with the “diS” label. If pass-
word is enabled, you will see it at the
entrance of the “Programming” menu.
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 connected
to the TTL serial port which allows programming quickly the instrument parameters. The operation is performed as follows:
Format
This command allows copy card formatting, an operation recommended in case
of first use.
Warning: if the copy card has been programmed, using the “Fr” the data entered
are erased. This operation cannot be cancelled.
Upload
This operation loads the programming
parameters from the instrument.
Download
This operation downloads to the instrument the programming parameters.
The operations are performed accessing
the folder identified by the “FPr” label and
selecting, according to the case, “UL”, “dL”
or “Fr” commands; the operation is confirmed by pressing the “set” key. If the
operation is successful an “y” is displayed,
on the contrary, if it fails a “n” will be displayed.

ELECTRICAL
WIRING
Attention! Never work on electrical connections when the machine is switched on.
The instrument is equipped with screw terminal boards for connection of electrical
cables with a diameter of 2.5 mm
2
(one
conductor only per terminal for power
connections).
For the capacity of the terminals, see the
label on the instrument.
The relay contacts are voltage free. Do not
exceed the maximum current allowed; in
case of higher loads, use an appropriate
contactor. Make sure the power supply
voltage complies with the one required by
the instrument.
In 12V versions the power supply must be
provided by a security transformer with
the protection of a delayed 250 mA fuse.
Probes have no connection polarity and
can be extended using a regular bipolar
cable (note that the extension of the
probes affects the EMC electromagnetic
compatibility of the instrument: pay
extreme attention to wiring).
Probe cables, power supply cables and the
TTL serial cables should be distant from
power cables.
