¶ Issue Description
-
Function: The door opening Hall sensor is located on the front cover of the AMS HT and is used to detect whether the AMS HT front cover is open. The reason for the HMS is that the door opening Hall sensor is disconnected;
-
Detection principle: Under normal circumstances, the voltage of the door opening Hall sensor is within a certain range. When the sensor is disconnected, the voltage will be too high to trigger an alarm.
-
Impact: It is impossible to detect whether the AMS HT front cover is open normally.
¶ Troubleshooting
¶ Tools, Equipment and Materials
Allen key
¶ Fault Isolation Process
-
Disassemble the AMS main frame and check whether the cable of the open-cover Hall effect sensor is connected normally. Re-plug both ends of the cable to ensure that it is firmly connected to the cover-opening Hall board and the main board.
-
If the error persists after re-plugging the cable, the sensor itself may be faulty and the open-cover Hall effect sensor assembly needs to be replaced.
If your AMS 2 Pro is still under warranty, please contact our after-sales support team for more help after trying the above troubleshooting steps.
