12
Alarm is related to Mains (Bus-L) voltage terminals connection
13
Alarm is related to Bus (Bus-R) voltage terminals connection
14
Wrong phases sequence means that e.g. generator/Mains voltages rotation is counter clockwise.
Typical reason is that two phases are swapped, e.g. phase L2 is connected to L3 controller
voltage terminal and phase L3 is connected to L2 controller voltage terminal.
15
Adjust setting of incorrectly set setpoints to get rid of the alarm. Use InteliMonitor to do that,
setpoints with out of range/incorrect setting are marked with yellow background
16
Use InteliMonitor to adjust incorrectly set statistics value. Go to
Monitor and Set statistics… to do
that.
17
It happens if 12V battery is used as power supply and voltage drops during engine starting (due to
high starter current). Use the I-LBA module to avoid this problem.
18
See the
How to check that communication between controllers works
chapter for more
information.
19
Check if generator voltage regulation works properly if this alarm is issued. See
Volt/PF control
adjustment
chapter in IGS-NT-x.y-Reference Guide for information about correct voltage
regulation setting.
20
Check if engine speed regulation works properly if this alarm is issued. See Sync
/Load control
adjustment
chapter in IGS-NT-x.y-Reference Guide for information about correct engine speed
regulation setting.
21
In GenConfig go to Options/Settings/Display and select Advanced.
22
Check either mains transformer or generator phases connection, one of transformer or generator
phases is connected the other way round (swap transformer or generator coil leads connection).
