1 Generator started by Sunny Island 5048 at
GenMan
2 Generator start through GenMan
3 GenMan warm up time begins
4 GenMan warm up time has expired,
connection signaled by GenMan at Sunny
Island 5048
5 Sunny Island 5048 connects generator
6 Current limit
7 Minimum run time (Sunny Island 5048) has
expired
8 Current is reduced, battery absorption phase
9 Loading process is completed, generator is
disconnected by Sunny Island 5048
10 Signal at GenMan
11 GenMan power down time has expired,
generator stopped
Warm up times, minimum run times and power down times are also maintained
for load dependent generator starts.

14.1.5 Limits and Power Adjustment

The voltage limits can be set using the "#242.01 GnVtgMin" and "#242.01
GnVtgMax" parameters and the frequency limits for generator operation can be set
using the "#242.05 GnFrqMin" and "#242.06 GnFrqMax" parameters. If the values
are outside these permitted limits, the generator is disconnected. Slightly restricted limits
are applied to generator connection.
The voltage and frequency limits are monitored in phases. The phase on the master
device must at least meet the defined limits to connect the generator. If the limits are not
maintained, slave devices, where applicable, connect or disconnect individually.
If the master device disconnects the generator, all slave devices are also
disconnected.
