Description
When generator voltage exceeds this
value and stays so for the time of
„Generator Abnormal Time‟, it is regarded
as over voltage and Generator Over
Voltage shutdown alarm is initiated. If the
voltage value is 1000V, over voltage
signal is not initiated.
When detected voltage falls below this
value and stays so for the time of
„generator abnormal state delay‟, it is
regarded as under voltage and Generator
Under Voltage shutdown
initiated. If the voltage value is 30V,
under voltage signal is not initiated.
When engine speed falls below this value
and stays so for 10 seconds, this is
regarded as under speed and under
speed alarm shutdown signal is sent.
When engine speed exceeds this value
and stays so for 2 seconds, this is
regarded as over speed and over speed
alarm shutdown signal is sent.
When generator frequency falls below
this value and stays so for 10 seconds, it
is regarded as under frequency and
under frequency alarm shutdown is
initiated.
When generator frequency exceeds this
value and stays so for 2 seconds, it is
regarded as an over frequency and over
frequency alarm shutdown is initiated.
When the temperature value of the
external temperature sensor exceeds this
threshold, high temperature signal is
sent. Detection starts after safety delay
and only concerns external temperature
sensor which connected
temperature sensor input port. If the set
value is 140, high temperature signal will
