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.

ENGLISH

GENERAL INFORMATIONS

WHAT IS THE USE

EC 6-141 is a power module studied for refrigerating systems management through the com-

pressor, evaporator fans and defrost (for temperature-time) management; the instrument was

studied to be used with a digital module.

There are three relay outputs of which one 16 (3) A @ 250 Vac relay for one 1½ HP @ 250 Vac

compressor management and two 8 (3) A @ 250 Vac relays for evaporator fans and defrost

system management.

EC 6-141 is available in the 71 x 90 mm (2.79 x 3.54 in., 4 DIN modules) case and it is studied

for DIN standard rail installation.

GETTING STARTED

INSTALLATION

EC 6-141 was studied for DIN EN 50022 standard rail installation according with DIN 43880

norms (the overall dimensions are related in Fig. 3, the fixing system suggested by the builder

is related in Fig. 4).

ADDITIONAL INFORMATIONS

- 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 6-141 is provided with one telephone connector for wired cable EC CC 502, EC CC 503,

EC CC 504, EC CC 505 or EC CC 510 (for the connection to the digital module) and it is provided

with three screw terminal blocks for cables up to 2.5 mm² (0.38 in.², for the connection to the

power supply, measure inputs and outputs) located on the instrument frontal panel (the con-

nections 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

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 di-

rectly 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 19 and 22 are derived to the local power supply, even if the instrument is

apparently turned off

- give the probes a protection able to insulate them against possible contacts with

metal parts or use insulated probes

- give the outputs a protection able to protect them 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. 5, the LED L1 turning ON.

The LED L1 is associated to the instrument status, it is turned ON during the status ON and it

is turned OFF during the status OFF.

To manage the resources of the power module see the chapter USE of the Operating instruc-

tions of the connected digital module.

SIGNALS

If the LED L1 is turned ON it means that the instrument is in the status ON.
