signal via configurable input port)
When genset voltage is over the point,
generator over voltage is active. When the
point is 620V, it does not detect over voltage
signal.
When generator voltage is under the point,
generator under voltage is active. When the
point is 30V, it does not detect under voltage
signal.
When generator frequency is over the point,
over frequency is active, gen over frequency
signal will be sent.
When generator frequency is lower than the
point, under frequency is active, gen under
frequency signal will be sent.
Gen Over Current Warn
Percentage
When load current is over the point, over
current is active. When this value is 0, warn
alarm signal won’t be sent.
When the temperature value of the external
temperature sensor exceeds the set value,
“High Temperature” timer is initiated. Detecting
only after safety on delay has expired. If the set
value is 140, high temperature signal will not
be sent (this only concerns external
temperature sensor, not high temperature
signal via config. input port).
When the external pressure sensor value falls
below this set value, “Low Oil Pressure” timer is
initiated. Detecting only after safety on delay
has expired. If the set value is 0, low oil
pressure signal will not be sent (this only
concerns pressure sensor and does not
concern low oil pressure warning signal via
configurable input port)

When generator voltage exceeds shutdown
value and last for a while, gen over volt
shutdown is active.
When generator frequency exceeds shutdown
value and last for a while, gen over freq
shutdown is active.
