IMPORTANT:

The use of this new instrument is easy; but for safety reasons, it is

important read these instructions carefully before the installation or

before the use and follow all additional informations.

It is very important keep these instructions with the instrument for future

consultations.

WHAT IS THE USE

EC 2-314 is a small size digital thermometer; the instrument can be supplied from main

voltage (230 Vac) with a very low power consumption (0.35 VA).

In factory the instrument gets preset to accept at the measure input PTC probes

(990 Ohm @ +25 °C); adjustments of the displayed value can be done through the

suitable trimmer.

EC 2-314 is available in the 62 x 28 mm (2.44 x 1.10 in.) case and it is studied for panel

mounting with elastic fins.

INSTALLATION

EC 2-314 was studied for panel mounting, panel cutout 58 x 25 mm (2.28 x 0.98 in.),

with elastic fins (the overall dimensions and the panel cutout are related in Fig. 3, the

fixing system suggested by the builder is related in Fig. 4).

ADDITIONAL INFORMATIONS

- the panel thickness must be included from 1 to 3 mm (0.04 to 0.11 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.

ELECTRICAL CONNECTION

EC 2-314 is provided with two screw terminal blocks for cables up to 2.5 mm² (0.38 in.²,

for the connection to the power supply and measure input), located on the instrument

back panel (the connections to derive are related in Fig. 5 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 1 and 2 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).

PRELIMINARY INFORMATIONS

After derived the connections related in Fig. 5, during the normal functioning the instrument

displays the temperature read by the probe; adjustments of the displayed value can be done

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).

ALARMSALARMS

ALARMS

If the instrument displays the indication “E0” flashing (probe failure alarm) it means that: the

kind of connected probe is not proper (verify the kind of connected probe), the probe is faulty

(verify the probe integrity), there is a mistake in the instrument-probe connection (verify the

instrument-probe connection integrity), the temperature read by the probe is outside the limits

permitted by the probe in use (verify that the temperature near the probe be inside the limits

permitted by the probe); inactive.

ADDITIONAL INFORMATIONS

- the effective probes working range principally depends from the kind of sensor and

from the material that forms the bulb and the cable.
