TM120/TM150 Temperature Fault Channel 0

What does F35207 mean?

This fault is triggered when the actual temperature (r4105[0]) for channel 0 on the Terminal Module 120 (TM120) or Terminal Module 150 (TM150) exceeds its configured fault threshold (p4102[1]), or if an associated timer (p4103[0]) 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.

• High ambient temperature within the control cabinet or immediate vicinity of the monitored equipment, exceeding the module's rated operating conditions.
• Excessive load on the component connected to channel 0, causing its operational temperature to exceed safe limits.
• Faulty temperature sensor connected to channel 0, inaccurately reporting a higher temperature reading for r4105[0].
• Blocked ventilation openings, dust accumulation on heat sinks, or cooling fan malfunction affecting the TM120/TM150 module or the monitored component.
• Parameter p4102[1] (Temperature fault threshold channel 0) set too low for the application's normal operating conditions, leading to premature tripping.

Click steps to track your progress.

1. 1

   Measure the actual temperature of the monitored component using an external thermal imaging camera or calibrated thermometer and compare it with r4105[0].

2. 2

   Inspect and thoroughly clean all cooling fins, fans, and ventilation openings on the TM120/TM150 module and the equipment connected to channel 0.

3. 3

   Verify the integrity and connections of the temperature sensor wiring for channel 0 from the sensor to the TM120/TM150 terminal block for looseness or corrosion.

4. 4

   Review the operational load on the equipment monitored by channel 0 to ensure it is not exceeding its design limits or duty cycle.

5. 5

   If the actual temperature is confirmed within safe limits but r4105[0] remains high, replace the temperature sensor associated with channel 0.

6. 6

   If thorough analysis confirms safe operating temperatures are consistently above the current fault setting, increase parameter p4102[1] (Fault threshold channel 0) to an appropriate value, ensuring adequate safety margin.
