Symptoms

Possible Causes

  • Separator element saturated with oil and contaminants

Troubleshooting Steps

  1. Step 1: Measure pressure drop across the separator
    Drop exceeds the replacement threshold
  2. Step 2: Replace the oil separator element
    New element is installed correctly
  3. Step 3: Verify oil carry-over is within normal range
    Oil consumption is within specification

How to Reset

To reset: Replace the oil separator, then clear the alarm.
