WHAT IS THE USE

EC 6-105 is a timer studied for defrost management (for time-safety temperature) able to meet
a wide range of accuracy applications bound to time intervals in refrigeration field.

There are a key for the manual activation of a defrost cycle, a digital input for the remote stop­ping of a defrost cycle and two 8 (2) A @ 250 Vac relay outputs for evaporator fans and defrost
system management; through the controls present on the instrument frontal panel it is possi­ble to set the instrument to manage the defrost according with one’s requirements and to
establish the evaporator fans output activity.

EC 6-105 is available in the 53 x 90 mm (2.08 x 3.54 in., 3 DIN modules) case and it is studied
for DIN standard rail installation.

INSTALLATION

EC 6-105 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
(carpets, covers, etc.), heating sources (radiators, hot air ducts, etc.), locations
subject 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 6-105 is provided with four screw terminal blocks for cables up to 2.5 mm² (0.38in.², for the
connection to the power supply, digital input and outputs), located on the instrument frontal
panel (the connections 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 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 termi­nals 74 and 77 are derived to the local power supply, even if the instrument is
apparently turned off

- 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).

PRELIMINARY INFORMATIONS

After derived the connections related in Fig. 5, the instrument reproposes the last settings
stored.

Fig. 2

iu6105.wmf

EC 6-105 is provided with four microswitch and of two trimmer that permit to set the instru­ment according with one’s requirements (see the chapter CONFIGURABILITY).

The output K 1 is associated to the evaporator fans and it is forced to the status ON, except
during a defrost and an evaporator fans stoppage.

In the course of the 24 hours, at regular time intervals (defrost interval), the instrument auto­matically activates the number of defrost cycles established with the microswitch M1, M2 and
M3.

A defrost cycle provides two phases (defrost and evaporator fans stoppage) connected in cas­cade since the end of one automatically determines the passage to the following one.

The output K 2 is associated to the defrost and it remains continuously activated during the
defrost or as long as the defrost stopping digital input gets activated when the defrost ends
and the instrument automatically moves to the evaporator fans stoppage; during the defrost
the output K 1 gets forced to the status OFF.

Passed the evaporator fans stoppage length from the moment of the defrost end the defrost
cycle ends; during an evaporator fans stoppage the activation of the output K 1 gets disabled.

Keeping pushed for two seconds at least the key T1 the instrument activates a defrost cycle.

NUMBER OF AUTOMATIC DEFROST CYCLES IN THE COURSE OF THE 24 HOURS SETTING

To modify the number of automatic defrost cycles in the course of the 24 hours to position the
microswitch M1, M2 and M3 on the desired value (for instance to set three automatic defrost
cycles in the course of the 24 hours to position the microswitch M1 in position A and the
microswitch M2 and M3 in position B).

ADDITIONAL INFORMATIONS

- the modification of the number of automatic defrost cycles in the course of the 24
hours has not immediate effect; to obtain this effect, after the modification keep
pushed for two seconds at least the key

- the course of the defrost interval gets recorded each 10 minutes and it is stored in
a non volatile memory even if a lack of power supply happens; when the power
supply recovers the instrument reproposes the last setting stored

- if all microswitch are positioned in position A the instrument never automatically
activates a defrost cycle

- if the number of automatic defrost cycle in the course of the 24 hours is not a
submultiple of 24 the fractions in minutes of the defrost interval get cancelled
but accumulated and stored in a non volatile memory even if a lack of power
supply happens provoking an automatic adjustment of the last defrost cycle such
as to guarantee that the addition of defrost intervals even is equivalent to 24
hours.

DEFROST MAXIMUM LENGTH SETTING

To modify the defrost maximum length value to position the microswitch M4 on the desired
scale and to rotate the trimmer TR2 as long as the arrow indicates the desired value (for in­stance to set a defrost maximum length of twenty-seven minutes to position the microswitch
M4 in position B and to rotate the trimmer TR2 as long as the arrow indicates the notch
12/27).

ADDITIONAL INFORMATIONS

- the modification of the defrost maximum length value has not immediate effect; to
obtain this effect it must not be executed during the course of the value

- the course of the defrost maximum length value gets recorded each 10 minutes
and it is stored in a non volatile memory even if a lack of power supply happens;
when the power supply recovers the instrument reproposes the last setting stored

- if the defrost stopping digital input is activated the instrument never activates a
defrost cycle.

EVAPORATOR FANS STOPPAGE LENGTH SETTING

To modify the evaporator fans stoppage length to rotate the trimmer TR1 as long as the arrow
indicates the desired value (for instance to set an evaporator fans stoppage length of eight
minutes to rotate the trimmer TR1 as long as the arrow indicates the notch 8).

ADDITIONAL INFORMATIONS

- the modification of the evaporator fans stoppage length value has not immediate
effect; to obtain this effect it must not be executed during the course of the value

- the course of the evaporator fans stoppage length value gets recorded each 10
minutes and it is stored in a non volatile memory even if a lack of power supply
happens; when the power supply recovers the instrument reproposes the last set­ting stored.
