GENERAL INFORMA

GENERAL INFORMATIONS

TIONS

WHAT IS THE USE
EC 3-130 is an ON-OFF single output digital thermoregulator able to cover a temperature range

from -50 to +99 °C (-58 to +99 °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 3-130 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 3-130 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 3-130 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.

Fig. 2

iu3130.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 3-130 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 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.
