14.1.9 Stopping the Generator<br />

If the generator was started via the <strong>Sun</strong>ny Island (automatically or manually), it can be manually<br />

stopped at any time using the "540.01 GnManStr" parameter. This disconnects the generator<br />

(the minimum run time is not taken into account here) and the after-run time (Cool) is skipped.<br />

Afterwards, the system enters the stop time (Lock).<br />

DANGER!<br />

Danger to life due to high voltages.<br />

The follow-up time depends on the generator type. During the follow-up time, there is still<br />

grid voltage at the loads.<br />

• Wait until there is no voltage measurement.<br />

Generators with manual start option<br />

Generators with the "manual" start option can generally only be started and stopped at the<br />

generator.<br />

Generator start prevented<br />

If the generator start is to be disabled after a manual stop, this must be performed by setting<br />

the "235.01 GnAutoEna" parameter to "Off".<br />

14.1.10 Disturbances<br />

Reverse Power<br />

If the reverse power ("234.13 GnRvPwr" parameter) set for the "234.14 GnRvTm" time is exceeded,<br />

the generator is disconnected and stopped. The follow-up time (Cool, parameter<br />

"234.10 GnCoolTm") is skipped and the system transitions into the minimum stop time (Lock).<br />

After reverse power, connection is blocked for at least "231.03 ExtLkTm" or "234.09 GnStpTmMin".<br />

Reverse power<br />

Observe the reverse power which the <strong>Sun</strong>ny Island can generate. The generator must<br />

provide this protection, observe the indications of the generator manufacturers regarding<br />

this!<br />

Generator Failure<br />

If a generator failure is detected (failure on the master phase), the generator is disconnected<br />

immediately and a stop signal occurs on generator. The system enters the minimum stop time (Lock).<br />

Generator Phase Failure<br />

The failure of a phase (e.g. broken fuse) on a slave device is treated as a phase failure. The slave<br />

device then disconnects this phase. If the phase is detected as being available again, it is reconnected<br />

after the warm up time "234.12 GnWarmTm" has elapsed.<br />

The phase failure on the master device is treated as a generator failure (see above).<br />
