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).
If enabled, this monitoring function becomes only active if gener‐
ator power control is enabled and the active power setpoint is con‐
figured to "Import" or "Export" (refer to
Control" on page 276 ). If the measured import or export power
deviates from the power setpoint by a value exceeding the limit

2 [On] On Monitoring of the mains active power mismatch is carried out according to
the following parameters.
Off Monitoring is disabled.

This value refers to the mains rated active power (parameter

Notes
If the monitored active power mismatch falls below the threshold (minus the
hysteresis) before the delay expires the time will be reset.
