Exceeded Temperature Difference Between Measuring Points

¿Qué significa 8-1-1-1 ?

The EL1904 terminal has detected an excessive temperature difference between its internal measuring points. This can indicate uneven heating or cooling within the terminal, possibly due to poor installation, restricted airflow, or proximity to a localized heat source. This condition can lead to thermal stress on components.

• Discrepancy between two temperature sensors exceeds operational limits.
• Uneven heating or cooling across different zones of the equipment.
• Faulty or miscalibrated temperature sensor (e.g., P1-10 vs. P1-11).
• Improper installation or mounting of temperature probes.
• Flow or circulation issue impacting temperature distribution.

1. 1

   Inspect the terminal's installation position for obstructions to airflow or proximity to localized heat sources that could cause uneven temperature distribution.

2. 2

   Measure the ambient temperature around the EL1904 terminal using a calibrated thermometer.

3. 3

   Compare the measured ambient temperature to the permissible operating temperature range specified in the terminal's technical data sheet.
