Message text Meaning
ID
Operat. range failed Measured values not within operating range
2664 An alarm will be issued if ignition speed is exceeded and the measured values for generator and/or mains
are not within the configured operating range. No alarm will be issued in idle mode.
Overspeed 1 Engine overspeed, limit value 1
2112 The engine speed has exceeded the limit value 1 for engine overspeed for at least the configured time and
does not fall below the value of the hysteresis.
Overspeed 2 Engine overspeed, limit value 2
2113 The engine speed has exceeded the limit value 2 for engine overspeed for at least the configured time and
does not fall below the value of the hysteresis.
Parameter alignment LDSS parameter mismatch detected
4073 The easYgen has detected that not all LDSS parameters are configured identically at all participating units.
Refer to
parameters.
Para.alignment 4105 Parameters of 4105 partners are not aligned
5135 The easYgen has detected that the parameters of device(s) beeing member(s) of the AR-N-4105 system
are not aligned
Ph. rotation mismatch Generator/busbar/mains phase rotation different
2944 Generator, busbar (easYgen-3400/3500 only), and mains have different rotating fields. A CB closure is
blocked.
The phase rotation monitoring is always enabled and cannot be disabled.
Red stop lamp Red stop lamp, J1939 interface
15125 This watchdog monitors, whether a specific alarm bit is received from the CAN J1939 interface. This ena‐
bles to configure the control in a way that a reaction is caused by this bit (e.g. warning, shutdown). No
alarm can be indicated if the CAN communication fails.
Speed/freq. mismatch Difference in frequency/speed measurement alarm
2457 The speed differential between the generator frequency (ascertained by the generator voltage measure‐
ment) and the engine speed (measured by the MPU) has exceeded the configured limit value / differential
frequency for at least the configured time and has not fallen below the value of the hysteresis. The alarm
may also be triggered if the LogicsManager "ignition speed" is enabled and no electrical frequency is
detected as well as the other way round.
Start fail Failure of engine to start alarm
3325 The generator set has failed to start after the configured number of attempts. Depending on the configura‐
tion, no more start attempt will be carried out until the alarm is acknowledged.
Unbalanced load 1 Generator unbalanced load, limit value 1
2412 The generator current has exceeded the limit value 1 for generator unbalanced load for at least the config‐
ured time and does not fall below the value of the hysteresis.
Unbalanced load 2 Generator unbalanced load, limit value 2
2413 The generator current has exceeded the limit value 2 for generator unbalanced load for at least the config‐
ured time and does not fall below the value of the hysteresis.
Underspeed 1 Engine underspeed, limit value 1
2162 The engine speed has fallen below the limit value 1 for engine underspeed and has not exceeded the
value of the hysteresis.
