Device clean warning

What does A88C mean?

This warning is generated by an on-time timer, signaling that a specific device requires cleaning based on its operational duration. An auxiliary code in the event log indicates which timer is responsible for triggering this warning. Ignoring this warning can lead to reduced efficiency, overheating, or premature failure of the device.

• Operational time for a specific device (e.g., cooling fan, heat exchanger, optical sensor lens) has exceeded its cleaning interval set by an on-time timer (e.g., P3-30).
• Accumulation of dust, debris, or contaminants in a dirty industrial environment, shortening required cleaning intervals.
• The cleaning timer threshold P3-30 is configured too conservatively for the actual environmental conditions.
• Reduced performance or efficiency of the device due to accumulated dirt, triggering the timer.

Click steps to track your progress.

1. 1

   1. Consult event log auxiliary code to identify the specific device requiring cleaning.

2. 2

   2. Visually inspect the identified device for dust, debris, or contaminant buildup.

3. 3

   3. Verify the accumulated operational time (e.g., P3-31) and the set cleaning threshold (e.g., P3-30).

4. 4

   4. Clean the device thoroughly using appropriate methods (e.g., compressed air, specific cleaning solutions).

5. 5

   5. Reset the cleaning timer (e.g., via P3-32) and adjust P3-30 if the cleaning interval needs modification based on environment.
