WHAT IS THE USE
EC 3-L30 is an ON-OFF single output digital thermoregulator able to cover a temperature range
from -40 to +99 °C; the instrument can be supplied from main voltage (230 Vac).
In factory the instrument gets preset to accept at the measure input NTC probes used in this
field of applications at the moment.
Some parameters permit to set the thermoregulator for “cooling” or “heating” functioning, to
protect the connected load against overloads due to several starts repeated in a short time.
EC 3-L30 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-L30 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 (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-L30 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, measure input and output), 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 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 terminals 1 and 2 are derived to the local power supply, even if the instrument is apparently turned off
- the probe is connected to a main voltage terminal; use double insulation probes
- give the output a protection able to protect it against short circuit and overload
- 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. 6, during the normal functioning the instrument
displays the temperature read by the probe.
iu3130.wmf
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-L30 is provided with one working setpoint and 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).
The output K 1 is associated to the working setpoint, it remains activated continuously as long
as the temperature read by the probe reaches the working setpoint and when it rises above (if
the output was set for “cooling” functioning) or it falls below (if the output was set for “heating”
functioning) the working setpoint of the hysteresis value (differential) the output gets reactivated.
WORKING SETPOINT SETTING (WORKING TEMPERATURE)
To modify the working setpoint value keep pushed the key T3 (the instrument displays the
actual value) and at the same time push and release over and over the key T1 or T2 as long as
the instrument displays the desired value (keeping pushed the key T1 or T2 the value gets
decreased or increased more quickly): after the modification release the key T3 last; during the
pressure of the key T3 the LED L1 flashes quickly to indicate that a working setpoint setting
procedure is running (to the release of the key T3 the instrument automatically turns out from
the working setpoint setting procedure).
ADDITIONAL INFORMATIONS
- for the whole period of a corrupted memory data alarm the access to the working
setpoint setting procedure is refused
- the working setpoint is programmable within the limits established with the parameters r1 and r2
- the working setpoint value gets stored in a non volatile memory even if a lack of
power supply happens.
CONFIGURATION PARAMETERS SETTING
Keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the label /1).
To select a parameter push and release over and over the key T1 or T2 as long as the instrument displays the label of the desired parameter.
To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets decreased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To turn out from the configuration parameters setting procedure keep pushed at the same time
for four seconds at least the keys T1 and T2 or do not operate with the keys for fifty seconds
at least (time-out exit).
ADDITIONAL INFORMATIONS
- for the whole period of a corrupted memory data alarm the access to the configuration parameters setting procedure is refused
- the modification of a parameter value which unit of measure is the hour or the
minute or the second has not immediate effect; to obtain this effect it must not be
executed during the course of the value

SIGNALS
If the LED L1 is turned ON it means that the output K 1 is activated.
ALARMS
If the instrument displays the indication “E2” flashing (corrupted memory data alarm) it means
that there is a corruption of the configuration data in the memory (turn OFF and turn ON again
the instrument: if to the turning ON again the alarm does not disappear the instrument must be
replaced); during this alarm the access to the working setpoint setting and the configuration
parameters setting procedures is refused and the output K 1 gets forced to the status OFF.
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); during this alarm the output K 1 gets forced to the status OFF.
