Description
The alarm class is valid for
parameter
╚═▷ 3283 and ╚═▷
3284 .
For additional information refer to
╚═▷ “9.5.4 Alarm Classes”
3293 Self acknowledge 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 condition is no
longer detected.
The alarm must be acknowledged
and reset by manually pressing
the appropriate buttons or by
activating the LogicsManager
output "External
acknowledgment" (via a discrete
input or via an interface).
Notes
The self acknowledge is valid for
parameter
╚═▷ 3283 and ╚═▷
3284 .
3296 Mains decoupling by
QV 2 On The QV monitoring function is
linked to the mains decoupling
function with all its consequences
and is assigned to "Delay step 1"
(parameter
╚═▷ 3283 ).
[Off] The QV monitoring function is
ignored in the mains decoupling
function.

Phase shift
A vector/phase shift is defined as the sudden variation of the voltage curve which may be
caused by a major generator load change. It usually occurs, if the utility opens the MCB,
which causes a load change for the genset.
The genset control measures the duration of a cycle, where a new measurement is
started with each voltage passing through zero. The measured cycle duration will be
compared with an internal quartz-calibrated reference time to determine the cycle
duration difference of the voltage signal.
The phase shift monitoring is a very sensitive functionality and reacts according to the
settings on each sinus wave constellation.
Please be aware that under special circumstances it may come to a phase shift trip,
when switching elements are taken into the mains measurement lines because mains
voltage sensing lines are switched nearby the genset control.
