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).
The power produced by the generator is calculated from the
voltage and current values measured in accordance with how
parameters "Generator voltage measuring" (param‐
eter 1851 Ä p.
1850 Ä p.
The generator power limits may be configured for reduced power
and/or reverse power depending on the threshold values entered.
The note below explains how a reduced or reverse power limit is
configured.
If the single-phase or three-phase measured real power is below
the configured limit of the reduced load or below the configured
value of the reverse power, an alarm will be issued.
Refer to
for the triggering characteristic of this monitoring function.
The values for reverse /reduced power monitoring can be config‐
ured as follows:

97) are configured.
If this protective function is triggered, the display indi‐
cates "Gen. rev./red. pwr.1" or "Gen. rev./red. pwr.2"
and the logical command variable "06.12" or "06.13"
will be enabled.
