temperature signal via config. input port).
When the external pressure sensor value
falls below this threshold, low oil pressure
delay begins. Detection begins after
safely on delay. If the set value is 0, low
oil pressure signal is not sent (this only
concerns pressure sensor and does not
concern low oil pressure warning signal
via configurable input port)
When the liquid level of the external
sensor falls below this value and stays so
for 10 seconds, low liquid level signal is
sent and warning without shutdown is
initiated.
When battery voltage exceeds this value
and stays so for 20 seconds, Battery
Over Volts signal is sent and warning
without shutdown is initiated.
When battery voltage falls below this
value and stays so for 20 seconds,
Battery Under Volts signal is sent and
warning without shutdown is initiated.
Current transformer ratio default as
500:5.
It is the rated current of generator, which
is apply for calculating over current with
load.
Over current delay starts when current
with load is greater than value of full-load
current multiply over current percentage.
When current with load exceeds preset
value and stays so over delay time, over
current alarm will be initiated.
