GENERAL INFORMA

GENERAL INFORMATIONS

TIONS

WHAT IS THE USE
EC 3-162 is a digital thermometer with two measure inputs able to cover a temperature range

from -50 to +150

C (-58 to +302

F).

In factory the instrument gets preset to accept at the measure inputs PTC probes used in this

field of applications at the moment; through the key present on the instrument frontal panel it

is possible to select the modality with which to display the temperatures read by the probes

(automatic or manual).
EC 3-162 is available in the 74 x 32 mm (2.91 x 1.25 in.) case and it is studied for panel

mounting with the equipped screw or spring brackets.

INSTALLATION
EC 3-162 was studied for panel mounting, panel cutout 71 x 29 mm (2.79 x 1.14 in.), with the

equipped screw or spring brackets (the overall dimensions and the panel cutout are related in

Fig. 3, the fixing systems suggested by the builder are related respectively in Fig. 4 and in

Fig. 5).
ADDITIONAL INFORMATIONS
-

the panel thickness must be included from 1 to 5 mm (0.04 to 0.19 in.)

verify if the using conditions (ambient temperature, humidity, etc.) are within the

limits indicated by the builder (see the chapter TECHNICAL DATA)

install the instrument in a location with a suitable ventilation, to avoid the inter-

nal overheating of the instrument

do not install the instrument near surfaces that can to obstruct the air-grating

(carpets, covers, etc.), heating sources (radiators, hot air ducts, etc.), locations

subject to direct sunlight, rain, humidity, excessive dust, mechanical vibrations

or bumps, devices with strong magnetos (microwave ovens, big speakers, etc.)

according with the safety norms, the protection against possible contacts with

electrical parts and parts protected with functional insulation only must be ensured

through a correct installation procedure of the instrument; all parts that ensure

the protection must be fixed so that they can not be removed if not with a tool

if not differently specified at the time of order, the instrument will be equipped

with screw brackets.

ELECTRICAL CONNECTION
EC 3-162 is provided with one screw terminal block for cables up to 2.5 mm² (0.38 in.², for the

connection to the power supply and measure inputs) and it is provided with one five poles

single line male connector (for the connection to the CLONE configurer/cloner and RICS super-

vision systems), located on the instrument back panel (the connections to derive are related in

Fig. 6 and they are checkable on the polyester label stuck on the instrument case).
ADDITIONAL INFORMATIONS
-

if the instrument is brought from a cold to a warm location, the humidity may

condense inside the instrument; wait about an hour before supply the instrument

verify if the operating power supply voltage, electrical frequency and power of

the instrument correspond to the local power supply (see the chapter TECHNICAL

DATA)

do not supply more instruments with the same transformer

if the instrument is installed on a vehicle, its power supply must be derived di-

rectly from the battery of the vehicle

give the instrument a protection able to limit the current absorbed in case of

failure

the instrument remains connected to the local power supply as long as the termi-

nals 7 and 8 are derived to the local power supply, even if the instrument is appar-

ently turned off

give the probes a protection able to insulate them against possible contacts with

metal parts or use insulated probes

do not try to repair the instrument; for the repairs apply to highly qualified staff

if you have any questions or problems concerning the instrument please consult

USE

PRELIMINARY INFORMATIONS
After derived the connections related in Fig. 6, during the normal functioning the instrument

displays the temperatures read by the probes.

If an alarm should be active the instrument displays the alarm code flashing as long as the

cause that has given it does not disappear (see the chapter SIGNALS AND ALARMS).
EC 3-162 is provided with two modality with which to display the temperatures read by the

probes (automatic and manual, see the paragraphs SELECTION OF THE MODALITY, AUTO-

MATIC MODALITY and MANUAL MODALITY).
The LED L1 is associated to the probe 1, it is turned ON during the display of the temperature

read by the probe 1 and it is turned OFF during the display of the temperature read by the

probe 2.
The LED L2 is associated to the probe 2, it is turned ON during the display of the temperature

read by the probe 2 and it is turned OFF during the display of the temperature read by the

probe 1.
The LED L3 is associated to the modality with which to display the temperatures read by the

probes, it is turned ON during the automatic modality and it is turned OFF during the manual

modality.

SELECTION OF THE MODALITY
To select a modality keep pushed for four seconds at least the key T1 (passed four seconds the

LED L3 turning ON or turning OFF).
ADDITIONAL INFORMATIONS
-

for the whole period of a corrupted memory data alarm the selection of the modality

with which to display the temperatures read by the probes is refused

the selected modality gets stored in a non volatile memory even if a lack of power

supply happens.

AUTOMATIC MODALITY
The instrument displays the temperature read by the probe 1 alternated to the temperature

read by the probe 2.
ADDITIONAL INFORMATIONS
-

the temperature read by a probe gets displayed for five seconds.

MANUAL MODALITY
The instrument displays the temperature read by the probe 1.
To display the temperature read by the probe 2 push and release the key T1 (to the release of

the key T1 the LED L1 turning OFF and the LED L2 turning ON).
To display the temperature read by the probe 1 again push and release the key T1 (to the

release of the key T1 the LED L1 turning ON and the LED L2 turning OFF).
ADDITIONAL INFORMATIONS
-

the selection of the temperature read by a probe gets stored in a non volatile memory

even if a lack of power supply happens.

SIGNALS AND ALARMS

SIGNALS
If the LED L1 is turned ON it means that the display of the temperature read by the probe 1 is

running.
