General

AIM-M10 medical intelligent insulation monitoring instrument adopts advanced micro controller 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. AIM-M10 is usually combined with AITR series medical isolation transformer AKH-0.66P26 current transformer and AID10/150 centralized alarm display device.

Function

1) Real-time monitoring and fault alarming of the ground insulation resistance,

2) Tansformer 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 Instructions

Indicator light

Instructions

On

When the device is in normal operation, the indicator flashes, and the flickering frequency is about once a second.

Insulation

When the insulation resistance exceeds the alarm setting value, or when FK 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 Problems

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 display: FK break, Insulation indicator lighting

Terminal 1 and terminal 2 of AIM-M10 are not reliably connected to LEB.

Check the connection and make sure it is reliable.

LCD display: TC break, Overtemp indicator lighting.

The terminals 17, 18 of AIM-M10 are not reliably connected to the two ST terminals of the isolation transformer.

Check the connection and make sure it is correct.

LCD display: insulation fault, Insulation indicator lighting

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-M10 is not connected properly.

Check the connection of terminals 11 and 12 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.
