Temperature Fault 1

Hva betyr 111 ?

One or more temperature input signals (configured in P3.9.6.1) have exceeded the alarm limit (P3.9.6.2) or the fault limit (P3.9.6.3). This indicates an overtemperature condition in a monitored area or a problem with the temperature sensing circuit. Unresolved overtemperature can lead to equipment damage.

• Excessive ambient temperature in the monitored area, exceeding the design limits of the equipment.
• Malfunction of cooling system components (e.g., cooling fan failure, blocked air vents) specific to the monitored zone.
• Parameter P3.9.6.3 (Temperature Fault Limit) or P3.9.6.2 (Temperature Alarm Limit) set too low, triggering prematurely under normal operating conditions.
• Degradation or incorrect placement of the temperature sensor (e.g., RTD, thermocouple) configured in P3.9.6.1, causing an inaccurate high reading.
• Overload condition on equipment monitored by Temperature Fault 1, generating excessive heat.

1. 1

   1. Measure the actual temperature in the monitored zone using an independent calibrated temperature probe and compare with the indicated value in P3.9.6.1.

2. 2

   2. Inspect and verify operation of all cooling components (e.g., fans, heat exchangers) for the monitored equipment, ensuring free airflow.

3. 3

   3. Review the settings of parameters P3.9.6.2 (Alarm Limit) and P3.9.6.3 (Fault Limit), adjusting them if they are misconfigured for the application.

4. 4

   4. Verify the resistance or voltage output of the temperature sensor (P3.9.6.1) according to its type (e.g., PT100 resistance, thermocouple mV output) at the sensor terminals.

5. 5

   5. Clean any dust or debris from cooling fins or vents of the monitored equipment to improve heat dissipation.
