TM150 Temperature Alarm Channel 10

¿Qué significa A35416 ?

This alarm is initiated when the actual temperature (r4105[10]) for channel 10 on Terminal Module 150 (TM150) exceeds its configured alarm threshold (p4102[20]). A timer (p4103[10]) is also started. The alarm will clear once the temperature falls below the threshold, factoring in the defined hysteresis (p4118[10]).

• Component connected to TM150 channel 10 experiencing an elevated temperature due to an unexpected increase in operational demand or friction.
• Alarm limit p4102[20] is set below the normal operating temperature range of the monitored component.
• Deterioration of the component's thermal grease or interface material, impairing heat transfer to the sensor.
• Electromagnetic interference (EMI) severely disrupting the TM150 channel 10 input, causing spurious high readings.
• Partial blockage of air vents or cooling passages for the monitored component, leading to heat buildup.

1. 1

   1. Monitor the real-time temperature value r4105[10] and the status of the alarm timer p4103[10].

2. 2

   2. Adjust the alarm threshold p4102[20] based on the component's safe operating temperature range specified by the manufacturer.

3. 3

   3. Verify the physical contact of the temperature sensor with the component and reapply thermal paste if necessary.

4. 4

   4. Inspect the sensor cable for TM150 channel 10 for proper shielding and grounding to mitigate EMI.

5. 5

   5. Remove any obstructions from the cooling system of the component and ensure proper airflow.
