GENERAL INFORMA

GENERAL INFORMATIONS

TIONS

WHAT IS THE USE
EC 6-PCT is a configurable current transmitter studied to be used with some of the devices

built by Every Control provided with serial port of which it is able to display and to convert the

acquired quantity in a 4-20 mA signal; through the keys present on the instrument frontal panel

it is possible to operate on other functions as the output current and the device software code

display.
EC 6-PCT 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-PCT 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-PCT 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, device serial interface and 4-20 mA output) and it is pro-

vided with one five poles single line female connector (for the connection to the CLONE

configurer/cloner and RICS supervision systems), 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 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 75 and 77 are derived to the local power supply, even if the instrument is

apparently turned off

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, during the normal functioning the instrument

displays the acquired quantity by the device.

If an alarm should be active the instrument displays the alarm code flashing as long as the

cause that has given it does not disappear (see the chapter SIGNALS AND ALARMS).
EC 6-PCT 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 4-20 mA output signal is proportional to the acquired quantity in every point between the

acquired quantity values corresponding to 4 and 20 mA.
Pushing and releasing the key T1 the instrument displays the output current (the unit of meas-

ure is the thousandth of Ampere): after displayed the output current push and release the key

T1 (to the release of the key T1 the instrument displays the acquired quantity by the device

again, passed four seconds from the first release of the key T1 without operated with the keys

the instrument automatically turns out from the output current display procedure).
Keeping pushed for four seconds at least the key T2 the instrument displays the device soft-

ware code for four seconds (for instance if the instrument displays 2608, it means that the

device software code is 26 release 08).
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 for two seconds at least the key T3 (passed two

seconds the instrument displays the label PA and the LED L1 turning ON).
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 push and release the key T3 (to the release of the key T3 the

instrument displays the actual value) and 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 push and release the key T3

(to the release of the key T3 the instrument displays the label of the parameter again); for the

four seconds following the first release of the key T3 or following the release of the key T1 or

T2 the instrument displays the set value and the LED L1 flashes to indicate that a configuration

parameter setting procedure is running (passed four seconds from the first release of the key

T3 or from the release of the key T1 or T2 without operated with the keys the instrument

automatically turns out from the configuration parameter setting procedure).
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 keep pushed for two seconds at least the key T3

or do not operate with the keys for four seconds at least (time-out exit).
To gain access to the second level enter inside the first level and select the label PA.
Push and release the key T3 (to the release of the key T3 the instrument displays the actual

value) and 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 push and release the key T3 (to the release of the key T3 the instrument

displays the label PA again) and keep pushed at the same time for four seconds at least the
