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 3-132 is an ON-OFF two outputs digital thermoregulator able to cover a temperature range

from -99 to +999 °C (-99 to +999 °F).

In factory the instrument gets preset to accept at the measure input PTC/NTC probes or “J”/”K”

thermocouples or 2/3 wires Pt 100 probes or 2 and 3 wires 0/4-20 mA temperature transduc-

ers (in this last case it is possible to set the reading scale).

This device can be set to execute one of the following kind of regulation: with an independent

working setpoint and the second relative to the first, with two independent working setpoint (in

these two cases each output can be set for “cooling” or “heating” functioning), with “neutral

zone” functioning.

EC 3-132 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 3-132 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 3-132 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 outputs) 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 outputs a protection able to protect them against short circuit and overload

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 3-132 is provided with two 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).

During the regulations with an independent working setpoint and the second relative to the first

and with two independent working setpoint, the output K 1 is associated to the first working

setpoint, the output K 2 is associated to the second working setpoint, they remain activated

continuously as long as the temperature read by the probe reaches the working setpoint and

when it rises above (if the outputs were set for “cooling” functioning) or it falls below (if the

outputs were set for “heating” functioning) the respective working setpoint of the hysteresis

value (differential) the outputs get reactivated.

During the regulation with “neutral zone” the output K 1 remains activated continuously as long

as the temperature read by the probe reaches the working setpoint and when it rises above the

working setpoint of the “neutral zone” value the output gets reactivated; likewise the output

K 2 remains activated continuously as long as the temperature read by the probe reaches the

working setpoint and when it falls below the working setpoint of the “neutral zone” value the

output gets reactivated.

WORKING SETPOINT SETTING (WORKING TEMPERATURE)

To modify the first 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; for the

two seconds following the release of the key T3 the instrument displays the established value

and the LED L1 flashes quickly to indicate that a first working setpoint setting procedure is

running (passed the two seconds from the release of the key T3 without operated with the keys

the instrument automatically turns out from the working setpoint setting procedure).

To modify the second working setpoint value release and keep pushed the key T3 during the

flashing of the LED L1 (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 L2 flashes

quickly to indicate that a second working setpoint setting procedure is running (to the release

of the key T3 the instrument automatically turns out from the working setpoint setting proce-

dure).

ADDITIONAL INFORMATIONS

- for the whole period of a corrupted memory data alarm the access to the working

setpoint setting procedure is refused

- if the parameter -/0 has value 3 the second working setpoint does not exist

- the first working setpoint is programmable within the limits established with the

parameters rA1 and rA2
