Temperature Fault 2

Was bedeutet 112 ?

One or more temperature input signals (configured in P3.9.6.5) have exceeded the alarm limit (P3.9.6.6) or the fault limit (P3.9.6.7). This signifies an overtemperature condition in a second monitored area or an issue with the second set of temperature sensing inputs. Ignoring this can lead to critical component failure.

• Sustained mechanical friction or bearing failure in the equipment monitored by Temperature Fault 2, generating localized heat.
• Obstruction of cooling air intake or exhaust vents specific to the second monitored area, leading to heat buildup.
• Incorrect calibration or wiring of the temperature sensor configured in P3.9.6.5, resulting in an erroneously high signal.
• Parameter P3.9.6.7 (Temperature Fault Limit) or P3.9.6.6 (Temperature Alarm Limit) configured below the normal operating temperature range of the monitored component.
• Electrical component failure (e.g., short circuit, excessive current) within the second monitored zone causing localized overheating.

1. 1

   1. Use an infrared thermometer or calibrated probe to verify the actual temperature at the location of the sensor associated with P3.9.6.5.

2. 2

   2. Confirm that cooling fans or heat dissipation mechanisms for the equipment linked to P3.9.6.5 are fully operational and unobstructed.

3. 3

   3. Examine the configuration of parameters P3.9.6.6 (Alarm Limit) and P3.9.6.7 (Fault Limit) to ensure they match the safe operating parameters of the monitored component.

4. 4

   4. Disconnect the temperature sensor (P3.9.6.5) and measure its intrinsic resistance (for RTD) or voltage (for thermocouple) at ambient temperature, comparing to manufacturer data.

5. 5

   5. Inspect internal components of the monitored equipment for signs of mechanical binding, excessive friction, or electrical hotspots.
