General

AIM-M200 medical intelligent insulation monitoring instrument adopts advanced microcontroller technology, which has high integration, compact size, convenient installation and integrates intelligence, digitalization and networking in one. It is ideal selection for insulation monitoring of isolation power system in Class 2 medical locations such as operating room and intensive care unit.

Function

1) Real time monitor and fault alarm of the ground insulation resistance,
2) Transformer load current and transformer winding temperature of the monitored IT system,
3) Be used with insulation fault locator, remotely starting fault-locating and displaying locating results when there are insulation faults,
4) Real-time monitor the line disconnection fault, temperature sensor disconnection fault and the functional grounding line disconnection fault of the monitored system, and give the alarm indication within 2S after the fault occurs,
5) Relay alarm output, LED alarm indication and other faults indication functions,
6) Used for centralized alarm and display instrument, test signal generator, insulation fault locator and upper computer management software communications, and can monitor the operation status of IT system in real time.
7) Events logging function, which can record alarm occurrence time and fault type and is convenient for operation personnel to analyze the operation conditions of system and promptly eliminate the faults.

LED Indicator Instruction

Indicator status	Instruction
On	When the device is in normal operation, the indicator flashes, and the flickering frequency is about once a second.
Comm	Indicate communication status, when there is data transmission, the indicator flashes.
Insulation	When the insulation resistance exceeds the alarm setting value, or when FK/LL is disconnected, the indicator flashes to alarm.
Overload	When the system load current exceeds the alarm setting value, the indicator flashes to alarm
Overtemp	When the transformer temperature exceeds the alarm setting value or the temperature sensor wiring is disconnected, the indicator flashes to alarm.

Common Problem

Make sure the connection is correct before the system is powered on. For common problems, according to the fault phenomena in the table below, targeted investigation can be carried out.

Fault phenomenon	Possible causes and troubleshooting
LCD: LL open, the Insulation indicator is lit.	Terminal 4 and terminal 5 of AIM-M200 are not reliably connected to L1 and L2 of the IT system. Check the connection and make sure it is reliable.
LCD: FK open, the Insulation indicator is lit.	Terminal 13 and terminal 14 of AIM-M200 are not reliably connected to LEB. Check the connection and make sure it is reliable.
LCD: TC open, the Overtemp indicator is lit.	Terminal 11 and terminal 12 of AIM-M200 are not reliably connected to the two ST terminals of the isolation transformer. Check the connection and make sure it is correct.
LCD: insulation fault, the Insulation indicator is lit.	At least one of the L1 and L2 wires in IT system has grounding fault, which can be restored to normal after removal.
The device can't light up.	The working power supply of AIM-M200 is not connected properly. Check the connection of terminals 1 and 2 and make sure it is correct

Note: All the above faults should be checked by power off, and the wiring should be adjusted until everything is normal.
