EC 3-563 is a three digit pressure monitor designed to work with current output 0-20 mA or 4-20 mA 2 or 3 wires
pressure transducers.
In factory, the instrument gets programmed to accept, at the input, one of the Every Control transducers (EC PRS 00,
EC PRS 01, EC PRS 02 or EC PRS 03) that permit to cover a range of pressure between -0.5 and 250 bar; however, just
changing some parameters it is possible to connect the instrument to other transducers.
The electronical solutions of this instrument make it able to power-supply the transducers, as long as they can work
inside a range of supply-voltage between 9 an 20 V.
Failure of functioning, defective probe, corrupted memory-data or probe-signal outside the limits, are indicated by the
flashing display, in order to catch user's attention.
The possibility of field-reconfiguration and the chance of being connected in remote-measuring or remote assistance
network, makes it highly flexible in the use and able to meet the most different needs.
* Custom configuration through keyboard or Personal
Computer
* Possibility of field-configuration
* Easy integration with remote-assistance or remote-
measuring

MOUNTING
For a proper mounting, take note of the attached indications; be sure that the conditions of use (voltage of power-
supply, environment temperature, humidity) are inside the instrument working limits.
Voltage at terminal 12 is not stabilized. If the transducer is powered by the instrument, it should be verified that in all
working conditions, especially for high signal output, the voltage on the transducer does not drop below the
minimum working value, in order to guarantee a correct measure.
WARNING : according to the source of power-supply, find a protection able to limit the quantity of current
absorbed by the instrument in case the failure.
CONFIGURATION
Pushand keep it pushed for 4 sec. at least :
"PA" will appear on the display
Releaseand push it straight after:
the first modifiable parameter will appear on the screen
Release and pushuntil the requested parameter appears
Keep pushedfor 4 sec. at least :
the parameter value will appear on the screen
Keep pushed again for 4 sec. at least :
the displayed value start increasing at the speed of 1 digit for 1/2 sec.
Releaseat the reaching of the requested value.
WARNING: The parameter value gets increased at the speed of 1 digit for 1/2 sec., until the upper end of scale reaching,
afterwards the instrument returns to the lower end of scale, and from here it keeps increasing.
To exit the configuration
Push again after the selection of the last available parameter, or wait 50 seconds, or switch the power supply off
and then switch it on.
SIGNALS AND ALARMS
"E0" flashing on the display means one of the following defects: probe-signal outside the limits, defective probe or
wrong connection (in case of not connected probe, the indication "E0" will appear if the parameter is /0=30 (4-20
mA) and "0" if the parameter is /0=31 (0-20 mA)).
"E2" flashing on the display: failure of memorised configuration-data; try to switch the power-supply off, and then, switch
it on.

notes
N.B. On request, it is possible to configure the instrument with different unit of measure.
The transducers pressure ranges are to be considered as " relative to atmospheric pressure ";
the unit of measure is bar (1 bar = 0.1 MPa; 1 MPa = 10 bar).
