2
Blocked
without error

Setting mode: no commands are given
Test mode :
TEST mode (configurable by means of digital

synchronization in which synchronization takes
place normally by means of adjusting
commands, but the paralleling command is
sent via a configurable relay rather than the

TEST t on (parameter): paralleling command
is deliberately given
TEST U-Match (parameter): voltage adjusting
commands are deliberately given
TEST f-Match (parameter): frequency adjusting
commands are deliberately given.
