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]).

• Component connected to TM150 channel 8 is operating in an environment with high ambient temperatures, reducing its cooling effectiveness.
• Alarm threshold p4102[16] is incorrectly configured, leading to an alarm at normal operating temperatures.
• Reduced efficiency of the component due to aging, wear, or internal contamination, causing it to generate more heat.
• Intermittent connection issues at the sensor input terminals of TM150 channel 8, leading to unstable temperature readings.
• Failure of an auxiliary cooling device (e.g., external fan, cooling pump) associated with the component on channel 8.

Click steps to track your progress.

1. 1

   1. Read the current temperature r4105[8] from the drive and evaluate its trend over time for unusual patterns.

2. 2

   2. Confirm that the alarm threshold p4102[16] and the timer delay p4103[8] are correctly parameterized for the application.

3. 3

   3. Inspect the general cooling conditions of the area surrounding the component connected to channel 8, checking for proper ventilation.

4. 4

   4. Disconnect the sensor from TM150 channel 8 and perform a continuity and resistance test on the sensor wiring to the component.

5. 5

   5. Verify the operational status of any associated external cooling fans or liquid cooling systems for the monitored component.
