ON (blink)
Normal operation and time is synchronized with GPS (only if GPS is
connected)
If a GPS is connected both LEDs will blink shortly every ca 10 seconds. This indicates that
information is received correctly from the GPS unit. If you connect the GPS and this blink doesn’t
occur, troubleshoot the cable and port baud rate setting etc. Refer to chapter 8.
5.6 Connection alternatives
The electricity network contains various different configurations of instrument transformers (PT =
potential transformer, CT = current transformer). The UP-2210-R measure units support all the
standard connections. The unit is configured using PQ Online, which includes all known connection
options as pre-sets, with the relevant wiring diagram stored and illustrated using graphics. The
software also allows you to define the constants for the potential and current transformers used (PT,
CT).
