General
AID120 is usually combined with AIM-M100, AID120 is usually used in combination with AIM-M 100 for data exchange through RS485 communication. It is fit for embedding into operating room or nurse station internal wall installation which can monitor one set of AIM-M100 insulation monitoring device with the function of sound-light alarm on failures like insulation, overload, over temperature and equipment failure etc. and digital display and RS485communication.
Function
The insulation resistance alarm value, load current alarm value and transformer temperature alarm value of each system insulation monitoring instrument can be set up remotely.
When there are insulation faults, overload, excessive temperature rise of the voltage transfomer or wiring faults in any of the monitored system, centralized alarm and display instrument can provide corresponding sound and light alarm function, and can manually eliminate the alam sound.

Common problems
For common problems, the causes can be determined and the faults can be eliminated according to the phenomenon of each instrument and the fault types:
|
Fault phenomenon |
Possible causes and troubleshooting |
|
The instrument is not lit. |
The 24V power supply is not connected well. Check the wirings of 24V and G terminals and rewire. |
|
Communication indicator does not flash |
In the system, the AIM-M100 monitor communication line is not connected properly. Check the communication line and confirm whether the matching resistance is connected properly. |
