TM150 Temperature Fault Channel 8

Was bedeutet F35404 ?

This fault is triggered when the actual temperature (r4105[8]) for channel 8 on the Terminal Module 150 (TM150) exceeds its configured fault threshold (p4102[17]), or if an associated timer (p4103[8]) expires. If a BICO interconnection exists, this fault will cause the drive to shut down. The fault will persist until the temperature falls below the threshold (minus hysteresis) and is acknowledged.

• Excessive heat generation from the component connected to TM150 channel 8, indicating a potential mechanical issue or electrical overload.
• Higher-than-acceptable ambient temperature inside the control enclosure affecting the TM150 module's and monitored equipment's thermal performance.
• A defective temperature sensor on channel 8 that is providing a false high reading for r4105[8].
• Improperly functioning cooling components (e.g., fan failure, blocked airflow) for the TM150 module or the equipment on channel 8.
• Parameter p4102[17] (Temperature fault threshold channel 8) set to an unrealistically low value for the monitored equipment's operating range.

1. 1

   Use an independent, calibrated temperature probe to verify the actual temperature of the component on channel 8, cross-referencing r4105[8].

2. 2

   Check all cooling components like fans, vents, and heat sinks on the TM150 module and the equipment on channel 8 for cleanliness and functionality.

3. 3

   Inspect the wiring connections for the temperature sensor on channel 8 at the TM150 module for any loose terminals or signs of damage.

4. 4

   Review the recent operational history and load of the component connected to channel 8 to identify any conditions that could cause overheating.

5. 5

   If the component's measured temperature is normal but r4105[8] indicates high, replace the temperature sensor connected to TM150 channel 8.

6. 6

   If an engineering assessment deems it appropriate, increase parameter p4102[17] (Fault threshold channel 8) to a level that safely accommodates normal operation.
