String combiner
In the String combiner sub-menu you can view the detailed informa-
tions related the status and parameters for each input channel.
A summary tab is available to view the status and parameters for each
input channel and to set the "TRIGGER TIME" and the "GROUP" of the
channel:
• Trigger time: It allows you to set the minimum elapsed time of ab-
normal working condition needed to trigger an alarm event (current
unbalance, interrupted).
• Group: It allows you to set the individual group for each channel. For
a correct string monitoring it's necessary to assign at the channels,
that have the same configuration of the PV strings (number of strings,
type of panel and orientation), the same group.
For each channel a detailed status tab is available.
In these tabs it could be possible to set the number of the connected
strings for each input and the relative tolerance between the string cur-
rent and the maximum current of the assigned group of the channel
(only available for -SX2 / -SY2).
