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 2-311 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 with 990 Ohm @ +25
°C, +77 °F or NTC with 10 KOhm @ +25 °C, +77 °F and B=3435 or NTC with 100 KOhm @ +25
°C, +77 °F and B=3977 probes; adjustments of the displayed value can be done through the
suitable trimmer.
EC 2-311 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 2-311 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 2-311 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).

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).

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.
