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).
2 Yes Monitoring for fault conditions is not performed until engine delayed moni‐
toring is enabled. The engine monitoring delay time (param‐

parameters assigned this delay.
[No] Monitoring for this fault condition is continuously enabled regardless of engine
speed.
The power produced by the generator is calculated from the
voltage and current values measured in accordance with how

When the contoller detects that the system is operating isolated
from the mains, the Generator Overload MOP (refer to
Ä Chapter 4.4.1.9 "Generator Overload MOP (Level 1 & 2) ANSI#
32" on page 118 ) monitoring is disabled. If the measured gener‐
ator real power during an isolated operation is above the config‐
ured limit an alarm will be issued.
