CL Setting range Description
[Default]
2 [On] Undervoltage monitoring is carried out according to the following parameters.
Monitoring is performed at two levels. Both values may be configured inde‐
pendent from each other (prerequisite: Level 1 limit < Level 2 limit).
Off Monitoring is disabled for Level 1 limit and/or Level 2 limit.
2 45.0 to 150.0 % The percentage values that are to be monitored for each threshold limit are
defined here.
3004: [92.0 %]
If this value is reached or exceeded for at least the delay time without inter‐
3010: [90.0 %]
ruption, the action specified by the alarm class is initiated.
Notes
This value refers to the "Mains rated voltage" (parameter
2 0.02 to 99.99 s If the monitored mains voltage falls below the threshold value for the delay
time configured here, an alarm will be issued.
3005: [1.50 s]
3011: [0.06 s]
Notes
If the monitored mains voltage exceeds the threshold (plus the hysteresis)
again before the delay expires the time will be reset.
2 Class A/B/C/D/ Each limit may be assigned an independent alarm class that specifies what
E/F action should be taken when the limit is surpassed.
3001: [A]
3007: [B]

2 [Yes] The control unit automatically clears the alarm if the fault condition is no
longer detected.
No The control unit does not automatically reset the alarm when the fault condi‐
tion is no longer detected.
The alarm must be acknowledged and reset by manually pressing the appro‐
priate buttons or by activating the LogicsManager output "External acknowl‐
edgement" (via a discrete input or via an interface).
easYgen-2200/2500 | Genset Control
If this protective function is triggered, the display indi‐
cates "Mains undervoltage 1" or "Mains under‐
voltage 2" and the logical command variable "07.12" or
"07.13" will be enabled.
The mains undervoltage Level 2 limit configuration
parameters are located below the mains decoupling
function menu on the display.
