P19
Gen
Abnormal
Delay
(0-20.0)s
10.0
Alarm delay for gen under/over voltage.
P20
Gen Over Volt limit
for Shutdown
(30-6000)V
264
When generator voltage is higher than this
threshold and lasts for the set gen abnormal
delay, then it shall consider over voltage and
shutdown alarm will be initiated.
(No detection for over volt signals if it is set
as 60000V)
P21
Gen Under Volt limit
for Shutdown
(30-6000)V
196
When sample voltage falls below this
threshold and lasts for the delay time, it is
considered under voltage and shutdown
alarm shall be initiated.
(No detection for under volt signals if it is set
as 30V)
P22
Level
High
to
disable Fuel Pump
(0-100)%
80
When fuel level is over the pre-set value for
2s, fuel pump is off;
P23
Level Low to enable
Fuel Pump
(0-100)%
25
When fuel level is under the pre-set value for
2s, fuel pump is on;
P24
Under
Frequency
Shutdown
(0-75.0)Hz
45.0
When generator frequency falls below this
threshold (not 0) and lasts for the delay time,
then it is considered under frequecy and
shutdown alarm signal will be initiated.
P25
Over
Frequency
Shutdown
(0-75.0)Hz
57.0
When generator frequency is over than this
threshold and lasts for the delay time, then it
is considered over frequecy and shutdown
alarm signal will be initiated.
P26
Under
Frequency
Shutdown Delay
(0-60)s
10
When generator frequency falls below this
threshold (not 0) and lasts for the delay time,
then it is considered under frequecy and
shutdown alarm signal will be initiated.
P27
Over
Frequency
Shutdown Delay
(0-60)s
2
When generator frequency is over than this
threshold and lasts for the delay time, then it
is considered over frequecy and shutdown
alarm signal will be initiated.
P28
Temp.
High
Shutdown Value
(80-140)ºC
98
When outside temp. sensor is above this
value, and Temp. High signal is issued; This
is detected only after safety on delay and
only for externally connected Temp. sensor;
When set value is 140, Temp. High signal is
not issued (only for Temp. sensor, excluded
