WHAT IS THE USE
EC 3-161 is a configurable digital thermometer 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 input PTC/NTC probes used in

this field of applications at the moment; adjustments of the displayed value can be done through

the suitable parameter.
EC 3-161 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 3-161 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 internal

overheating of the instrument

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

pets, covers, etc.), heating sources (radiators, hot air ducts, etc.), locations sub-

ject 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 3-161 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 input) and it is provided with one five poles single

line male connector (for the connection to the CLONE configurer/cloner and RICS supervision

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 con-

dense 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 directly

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 8 and 9 are derived to the local power supply, even if the instrument is appar-

ently turned off

give the probe a protection able to insulate it 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

Every Control (see the chapter BUILDER DATA).

USE

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

displays the temperature read by the probe.

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 ALARMS).
EC 3-161 is provided with some configuration parameters that get stored in a non volatile

memory and that permit to set the instrument according with one’s requirements (see the

chapter CONFIGURABILITY).
CONFIGURATION PARAMETERS SETTING
Configuration parameters are arranged in families that can be recognized through the initial

letter of the label.
Keep pushed for four seconds at least the key T1 (passed four seconds the instrument displays

the label PA).
To select a parameter push and release over and over the key T1 as long as the instrument

displays the label of the desired parameter.
To modify the parameter value keep pushed for four seconds at least the key T1 (passed four

seconds the value gets automatically increased); after the modification release the key T1 (to

the release of the key T1 the instrument displays the label of the parameter again).
To turn out from the configuration parameters setting procedure push and release over and

over the key T1 as long as the instrument displays the temperature read by the probe or do not

operate with the key for fifty seconds at least (time-out exit).
ADDITIONAL INFORMATIONS
-

for the whole period of a corrupted memory data alarm the access to the configura-

tion parameters setting procedure is refused

the configuration parameters values get stored in a non volatile memory even if a

lack of power supply happens.
