TM150 Temperature Alarm Channel 8

What does A35414 mean?

This alarm is initiated when the actual temperature (r4105[8]) for channel 8 on Terminal Module 150 (TM150) exceeds its configured alarm threshold (p4102[16]). A timer (p4103[8]) is also started. The alarm will clear once the temperature falls below the threshold, factoring in the defined hysteresis (p4118[8]).

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check for any immediate causes of temperature increase for the affected component, such as temporary overloads or environmental factors.

2. 4

   Verify the temperature sensor operation and connection for channel 8.

3. 5

   Review the alarm threshold setting (p4102[16]) and hysteresis (p4118[8]) to ensure they are appropriate for the application.
