3 Phase 3 Wire
3 Phase 4 Wire
2
Mains under volt
55-330V(184V)
When the mains voltage is lower than the "low
voltage crank threshold" and comes into
mains low voltage delay(normal failure delay)
but still lower, then mains becomes invalid. If
the voltage become higher than "low voltage
revert threshold" during normal failure delay
time, then it will not alarm.
3
Revert under volt
55-330V(207V)
4
Mains over volt
55-330V(276V)
When the mains voltage is higher than the"
high voltage crank threshold" and comes into
mains high voltage delay(normal failure delay)
but still higher, then mains becomes invalid. If
the voltage become lower than "low voltage
revert threshold" during normal failure delay
time, then it will not alarm.
5
Revert over volt
55-330V(253V)
6
Mains normal
delay
0.0-3600.0S(10.0S)
The time from abnormal to normal, which is
used for ATS transfer.
7
Mains abnormal
delay
0.0-3600.0S(5.0S)
8
Loss of Phase
Loss of 1 Phase
Loss of 2 Phases
Loss of 3 Phases
Set the phase loss condition to judge whether
the mains is abnormal.
7)LCD setting
No
Parameter
Range(defaults)
Notes
1
Start screen
display
0-20.0s(5.0s)
Start screen display time,0: No-display.
2
Saving mode
5.0-6000.0s
(600.0s)
LCD light will be closed automatically without any
button pressed after delay.If setting as 6000s,
back light always lighted.
3
Homing display
5.0-600.0s
(600.0s)
The time when the page reverts back to the home
page .If setting as 600.0s:disabled.
4
LOGO delay
display under
standby
5.0-6000.0
(6000.0s)
Start screen will be opened without any button
pressed after delay.If setting as 6000.0s: disabled.
8)Self-define curve
NO
Parameter
Notes
1
Self-define temperature
curve
Sensor curve can be User-defined by panel buttons,
resistance and according value should be input,MAX 15
groups ,MIN 2 groups.
Rule: resistance should be input from small to
large.
2
Self-define fuel level curve

Symptoms
Possible Solutions
Controller no response
with power
Check DC voltage.
Check DC fuse.
Check if the terminal 1 and 2 is with battery voltage.
Genset shutdown
Check the water/cylinder temperature is too high or not;
