CL Setting range Description
[Default]
Notes
This parameter is only effective if start stop mode (parameter
is configured to "Generator load".
Refer to parameter
genset depending on the dynamic setting.
This parameter is not visible and therefore not configurable in the
easYgen-2000 Series. Please refer to
eter Alignment" on page 187 for details.
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‐
[20 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]
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.
The critical mode may be used to operate a fire engine pump or
any other critical operation which does not allow a shutdown of the
genset under any alarm conditions.
The LogicsManager is used to define the conditions that will enable
the critical mode like a discrete input (for conditions and explana‐
tion of programming refer to
Overview" on page 549 ).
