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.
GENERAL INFORMATIONS
WHAT IS THE USE
EC 3-131 is an ON-OFF single output digital thermoregulator 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.
Some parameters permit to set the thermoregulator to display the temperature in Fahrenheit
or Celsius degrees, for cooling or heating functioning, to protect the connected load against
overloads due to several starts repeated in a short time, to signal working conditions outside
the safety limits.
EC 3-131 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.
GETTING STARTED
INSTALLATION
EC 3-131 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 3-131 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) 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
- 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).
USE
PRELIMINARY INFORMATIONS
After derived the connections related in Fig. 6, during the normal functioning the instrument
displays the temperature read by the probe.
iu3131.wmf
If an alarm should be active the instrument displays the alarm code flashing and the buzzer
utters an intermittent beep as long as the cause that has given it does not disappear (see the
chapter SIGNALS AND ALARMS); pressure on the key T1 during an alarm permits to silence
the buzzer.
EC 3-131 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 ones
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 reacti-
vated.
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 param-
eters 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
Configuration parameters are arranged on two levels, to protect the most tricky settings against
undesirable violations and they are arranged in families that can be recognized through the
initial letter of the label.
To gain access to the first level keep pushed at the same time for four seconds at least the keys
T1 and T2 (passed four seconds the instrument displays the label PA).
To select a parameter of the first level 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 de-
creased 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 gain access to the second level enter inside the first level and select the label PA.

Fig. 2
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 -19 (keeping
pushed the key T1 or T2 the value gets decreased or increased more quickly): after the modi-
fication release the key T3 last (to the release of the key T3 the instrument displays the label PA
again); keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the first parameter of the second level).
To select a parameter of the second level 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 de-
creased 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 configura-
tion 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
- the configuration parameters values get 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 output K 1 is activated.
If the LED L1 flashes it means that a count of a disabling time to the output K 1 activation is
running (see the parameters C0, C1, C2 and C4).
ALARMS
If the instrument displays the indication E2 flashing and the buzzer utters an intermittent
beep (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 and the buzzer utters an intermittent
beep (probe failure alarm) it means that: the kind of connected probe is not proper (see the
parameter /0), the probe is faulty (verify the probe integrity), there is a mistake in the instru-
ment-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 tempera-
ture near the probe be inside the limits permitted by the probe); during this alarm the output
K 1 gets forced to the status established with the parameter C3.
If the instrument displays the temperature read by the probe flashing and the buzzer utters an
intermittent beep (temperature alarm) it means that the temperature read by the probe is
outside the limit established with the parameter A1 or A2 (see the parameters A0, A1 and A2);
