The device RGDAT-A70 has a current converter with output 4÷20 mA for sending the measurement of
phase current to a remote control unit. The current converter is galvanically insulated from the other
electronic circuits and from the auxiliary power of RGDAT-A70.
On the front of the device there are the following light signals:
three green LEDs
signaling the presence of phase voltages V4, V8 and V12
one white LED
signaling inversion of surveillance direction of the directional earth
fault protection
one orange LED
signaling trip of phase overcurrent protection (51) or earth fault
overcurrent protection (51N), memorized
one red LED
signaling trip of directional earth fault protection (67N), memorized
one red LED
(blinking)
signaling intervention of self-diagnostic function
Using a specific digital input it is possible to enable the inversion of surveillance direction of directional
earth fault protection.
The connection between RGDAT-A70 and remote control unit is made with components and
dimensions indicated in ENEL specification GSTP001. There is a multicore cable from the cable gland
placed on top of the metal container; its wires are connected to terminal block MB, according to
connection diagram shown in this manual.
On the electronic board of RGDAT-A70 there is a 9-pin D-Sub RS232 serial connector, which is used
for device configuration and for commissioning procedures.
A specific software, running under Microsoft Windows
®
(Windows XP and later), allows you to do
configuration, monitoring, checking and update the firmware of the device RGDAT-A70.
These operations are described in detail in the following chapters of this document.
Combined sensors
The combined sensors integrate the following functions into a single device:
post insulator
voltage transducer
current transducer
It is used one combined sensor for each phase.
For more detailed information on such devices, please refer to the document “CVS-P-24-O Technical
specifications” by Altea.
Combine RGDAT-A70 with sensors
To ensure the correct operation between RGDAT-A70 and combined sensors, you must use the type
of combined sensors with which the device was originally supplied.
On the front of the RGDAT-A70 and on the electronic board adhesive labels are applied, indicating
which type of combined sensors can be used with the specific RGDAT-A70, as shown in the following
table.
