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.
