Check whether the wirings of 220V power input are normal
and whether the voltage between the two terminals is
within the allowable input range.

The device is not
lit.
The 24V power supply is not connected well. Check the
wirings of No.1 and 2 terminals and rewire.
Unable to locate the
insulation fault
1)
The communication line with other devices in the
system is not connected well. Troubleshoot the
communication line and confirm whether the matching
resistors are well connected.
2)
The CAN address is not set up properly. Disconnect the
CAN bus of other connected system devices, and reset
CAN address through its corresponding insulation
monitoring device.
3)
Device problem, which is needed to return to the
factory to be solved.

The 24V power supply is not connected well. Check the
wirings of 24V and G terminals and rewire.
Communication
indicator does not
flash
1)
communication parameters are not set properly, check
communication parameters (address, baud rate).
2)
The communication line with other devices in the
system is not connected well. Troubleshoot the
communication line and confirm whether the matching
resistors are well connected.
Note: If the above faults occur, interrupt the power to troubleshoot, and adjust the wirings
until everything is normal.
9.3 Settings and debugging
1) After the system is powered on, set the AIM-M300(or AIM-M300/SG) load current alarm value
according to the capacity of the isolation transformer. The corresponding relations between alarm
current and isolation transformer capacity are: 45A---10kVA, 35A---8kVA, 28A---6.3kVA,
14A---3.15kVA. After you set up, follow the process step by step to exit and save the setting
parameters. The default alarm current value of the device is 35A, if the matching transformer is
8kVA, then this parameter does not need to be set.
