CL Setting range Description
[Default]
2 0 to 32000 s Load swings may exceed the threshold momentarily. In order to prevent the
engine from starting due to short-term load swings, a delay time may be con‐
[10 s]
figured.
The LDSS criterion for adding load must be exceeded without interruption for
this delay time, configured in seconds, prior to a start command being issued.
If the LDSS criterion for adding load is fallen below before the delay time
expires, the delay time is reset and a start command is not issued.
2 0 to 32000 s The command to start the next genset in case a genset exceeds rated load
will be issued after the delay configured here has expired.
[3 s]
Notes
This parameter becomes only effective in case a genset exceeds rated load
to achieve a faster start and overrides parameter
2 0 to 32000 s Load swings may fall below the threshold momentarily. In order to prevent the
engine from stopping due to short-term load swings, a delay time may be con‐
[60 s]
figured.
The load must remain below the hysteresis setpoint without interruption for
the delay time, configured in seconds, prior to a stop command being issued.
If the load exceeds the hysteresis setpoint before the delay time expires, the
delay time is reset and a stop command is not issued.
In case of a mains parallel operation (MCB closed), load-
dependent start stop is only enabled, if the gensets participates in
load sharing at the interchange point (all participating gensets must
be configured to the same setpoint).
CL Setting range Description
[Default]
2 0 to 65000 kW For the mains interchange (import/export) real power control to function, a
minimum generator power setpoint value is required to start the first genset.
[10 kW]
In many cases, it is desirable that the engine is prevented from starting unless
the generator will operate at a specific kW level or higher to ensure a reason‐
able degree of efficiency.
Example
The mains interchange must reach a level that will permit an 80 kW generator
to operate at a minimum load of 40 kW prior to the engine starting.
easYgen-2200/2500 | Genset Control
A minimum load threshold must be exceeded to start
the first genset, i.e. a genset will only be started if a
minimum load would be demanded from the generator.
There are dedicated LDSS parameters for mains par‐
allel operation.
