WHAT IS THE USE

EC 6-759 is an ON-OFF eight relay outputs digital pressure controller with analog output.
In factory the instrument gets preset to accept at the measure inputs 2 wires 4-20 mA pres-

sure transducers (it is possible to set the reading scale).
Some parameters permit to manage the analog output according with one’s requirements, to

set each relay output for “high or low pressure” functioning, to establish the pressure to asso­ciate to each relay output (pressure read by the probe 1 or pressure read by the probe 2).

EC 6-759 is available in the 106 x 90 mm (4.17 x 3.54 in., 6 DIN modules) case and it is studied
for DIN standard rail installation.

INSTALLATION

EC 6-759 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 6-759 is provided with six extractable screw terminal blocks for cables up to 2.5 mm²
(0.38in.², for the connection to the power supply, measure inputs, relay outputs and analog
output) 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 61 and 65 are derived to the local power supply, even if the instrument is
apparently turned off

- give the relay 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 executes an autotest.
Passed eight seconds the instrument automatically moves to the normal functioning.

iu6758.wmf

During the normal functioning the instrument displays the pressure read by the probe 1, ex­cept what established with the parameter /AL.

If an alarm should be active the instrument displays the alarm code as long as the cause that
has given it does not disappear (see the chapter SIGNALS AND ALARMS).

EC 6-759 is provided 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 first setpoint, ... . the output K 8 to the eighth, they remain

activated continuously as long as the pressure read by the probe 1 reaches the working setpoints
and when it rises above (if the outputs were set for “high pressure” functioning) or it falls
below (if the outputs were set for “low pressure” functioning) the respective working setpoint
of the hysteresis value (differential) the outputs get reactivated, except what established with
the parameters of the family rP.

To display the pressure read by the probe 2 keep pushed the key T3.

ANALOG OUTPUT

The 0-10 V analog output is associated to the pressure read by the probe 1, except what
established with the parameter /Au.

The analog output signal is proportional to the pressure read by the probe 1 in every point
between the pressure values corresponding to 0 and 10 V.

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 de­creased 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.
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 -19 (keeping
pushed the key T1 or T2 the value gets decreased or increased more quickly): after the modi­fication release the key T3 last (to the release of the key T3 the instrument displays the label PA
again); keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the first parameter of the second level).

To select a parameter of the second 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 de­creased 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 turn out from the configuration parameters setting procedure keep pushed at the same time
for four seconds at least the keys T1 and T2 or do not operate with the keys for fifty seconds
at least (time-out exit).

ADDITIONAL INFORMATIONS

- for the whole period of a corrupted memory data alarm the access to the configura­tion parameters setting procedure is refused

- the modification of a parameter value which unit of measure is the hour or the
minute or the second has not immediate effect; to obtain this effect it must not be
executed during the course of the value

- the modification of the parameters /6u, /7u, rP 1 ... 8 value has immediate effect; to
avoid damages to the connected users, it must be executed with the users not
connected

- the modification of the parameter /Au value has not immediate effect; to obtain this
effect, after the modification turn OFF and turn ON again the instrument

- the configuration parameters values get stored in a non volatile memory even if a
lack of power supply happens.

SIGNALS

If the LED L1 ... 8 is turned ON it means that the output K 1 ... 8 is activated.
If the LED L1 ... 8 flashes it means that a count of a disabling time to the output K 1 ... 8

activation is running (see the parameters C 0, C 1 and C 2).
If the instrument displays the indication “888” and the LED L1, ... and L8 are turned

ON it means that the autotest is running.

ALARMS

If the instrument displays the indication “E 2” (corrupted memory data alarm) it means that
there is a corruption of the configuration data in the memory (turn OFF and turn ON again the
instrument: if to the turning ON again the alarm does not disappear the instrument must be
replaced); during this alarm the access to the configuration parameters setting procedure is
refused, the outputs K 1 ... 8 get forced to the status OFF and the analog output signal is 0 V.

If the instrument displays the indication “E0A” (probe 1 failure alarm) it means that: the kind
of connected probe 1 is not proper (verify the kind of connected probe 1), the probe 1 is faulty
(verify the probe 1 integrity), there is a mistake in the instrument-probe 1 connection (verify
the instrument-probe 1 connection integrity), the pressure read by the probe 1 is outside the
limits permitted by the probe 1 in use (verify that the pressure near the probe 1 be inside the
limits permitted by the probe 1); during this alarm if the parameters rP1 ... 8 have value 0 the
outputs K 1 ... 8 get forced to the status established with the parameter C 3 and if the param­eter /Au has value 0 the analog output signal is 0 V.

If the instrument displays the indication “E0b” (probe 2 failure alarm) it means that there is
one of the faults saw in the previous case but referred to the probe 2; during this alarm if the
parameters rP1 ... 8 have value 1 the outputs K 1 ... 8 get forced to the status established with
the parameter C 3 and if the parameter /Au has value 1 the analog output signal is 0 V.

If the instrument displays the pressure read by the probe 2 and the indication “E0A” every four
seconds (probe 1 failure alarm) it means that there is one of the faults saw in the previous
case but referred to the probe 1 and that the pressure read by the probe 1 is associated to a
relay output; during this alarm if the parameters rP1 ... 8 have value 0 the outputs K 1 ... 8 get
forced to the status established with the parameter C 3 and if the parameter /Au has value 0 the
analog output signal is 0 V.

If the instrument displays the pressure read by the probe 1 and the indication “E0b” every four
seconds (probe 2 failure alarm) it means that there is one of the faults saw in the previous
case but referred to the probe 2 and that the pressure read by the probe 2 is associated to a
relay output; during this alarm if the parameters rP1 ... 8 have value 1 the outputs K 1 ... 8 get
forced to the status established with the parameter C 3 and if the parameter /Au has value 1 the
analog output signal is 0 V.
