To control output relays, select (or deselect) the related check-box and press the "Test relays" button.
To perform a verification routine of RGDAT-A70, press the "Check RGDAT" button. The execution of
the verification routine has an immediate visual feedback on RGDAT-A70 itself and ends
automatically after a few seconds.
To control the 4÷20 mA output current, use the proper cursor and one of two buttons on the side: the
"Full scale test" allows you to correlate the current value displayed below the cursor as if it were the
current measured by the current sensor connected to terminal block MA2 (I4); the output current
value is also a function of the full scale value set in the dialog box "Thresholds 51 51N 67N". The
button "Percentage test" is used to set the output current to a value related to the effective dynamic
range of the converter (can be useful when debugging).
During the execution of diagnostic procedures, the device RGDAT-A70 does not perform protection
functions.
When the diagnostic activity ends (that is when the dialog box is closed), the equipment RGDAT-A70
resumes its normal protection functions.
Note that RGDAT-A70 quits diagnostic mode if at least 5 minutes have elapsed without performing
any diagnostic activity.
The item "
Alarms reset
" switches off the trip signaling LEDs of thresholds 51, 51N and 67N (if
thresholds are no longer in trip conditions).
The item "
Reset events
" clears the event data recorded by RGDAT-A70.
