Figure 12-4: PVI-STRINGCOMB(-S) Status Panel
(5) Address and S/N: it shows the Field Number (FN) and the Serial Number
of the PVI-STRINGCOMB(-S) monitored. The RS485 address is also
shown, which is always the same as FN+1.
(6) Global data: These include the voltage and total current of the field. The
temperature inside the StringComb is also shown.
(7) Negative (-) String Fuse Status: This indicates the status of the fuses
from F11 to F20 with a green (OK) or red (FAILURE) signal.
(8) Positive (+) String Fuse Status: This indicates the status of the fuses
from F1 to F10 with a green (OK) or red (FAILURE) signal.
(9) String current and weight: the next figure shows how to interpret the
window in question:
Uncalibrated voltage
and current sensors
One or more fuses are
burnt
The overvoltage
protection is out of order
One or more cartridges
must be replaced
The internal temperature
exceeds the alarm value
The current of one or
more strings exceeds the
alarm value
The current of one or
more strings is not regular
Field voltage is out of
operation range
