DCC_103104431 Temperature Sensor Chip Alarm

DCC_103104431 Temperature Sensor Chip Alarm

Description

An AR538 detects its temperature every two minutes. This alarm is generated when the AR538 fails to detect its temperature.

Attribute

Alarm ID Alarm Severity Alarm Type
103104431 Major Equipment alarm

Impact on the System

The AR538 fails to detect its temperature. If the temperature of an AR is high, the AR may be damaged.

Possible Causes

  • The temperature sensor chip is faulty.
  • An inter-integrated circuit (IIC) communication fault occurs between the micro control unit (MCU) and temperature sensor chip.

Procedure

  1. Check alarm location information and confirm the information about the electrical meter on which the alarm occurs.
    1. Start the EEM, enter the user name and password, and click Go to log in to the EEM.
    2. Choose Monitoring > Alarm > Current Alarm to access the Current Alarm page and view the alarm list.
    3. Click next to the alarm. The system displays detailed information about the alarm, such as alarm location.
  2. Confirm the device that generates this alarm and check whether the temperature sensor chip of the device works properly.

    • If so, go to 3.
    • If not, rectify the temperature sensor chip fault. After the temperature sensor chip works properly, check whether the alarm is cleared.
      • If so, the process is ended.
      • If not, go to 3.

  3. Check whether the IIC communication between the MCU and temperature sensor chip is normal.

    • If so, collect alarm information and contact Huawei technical support personnel.
    • If not, rectify the IIC communication fault. After the IIC communication between the MCU and temperature sensor chip is normal, check whether the alarm is cleared.
      • If so, the process is ended.
      • If not, collect alarm information and contact Huawei technical support personnel.

Clearing

The alarm cannot be automatically cleared by the system and needs to be cleared manually.
