External warning 2

Hva betyr A982 ?

An external device configured as External Event 2 (parameters 31.03 and 31.04) has generated a warning. This indicates a potential issue with external equipment or sensors that should be investigated, though it may not cause an immediate drive trip. Addressing warnings proactively prevents escalation to faults.

• Elevated temperature on an external motor bearing, activating a thermal switch connected to the drive's configured digital input (P31.03, P31.04).
• Low fluid level in an external process tank, causing a level switch to trigger a warning signal on the digital input.
• Minor mechanical obstruction or drag in the connected machinery, increasing motor current marginally and triggering an external current monitoring relay set to a warning threshold.
• Loose wire connection or corrosion on the external sensor's output terminal, leading to an intermittent warning signal on the input.

1. 1

   1. Determine the specific external sensor or device linked to the digital input configured by P31.03 (External Event 2 source).

2. 2

   2. Use a multimeter to verify the voltage level at the drive's digital input terminal corresponding to the external warning.

3. 3

   3. Inspect the external sensor and its associated process (e.g., temperature, pressure, level) for any out-of-range conditions that would trigger the warning.

4. 4

   4. Confirm that P31.03 (External Event 2 source) and P31.04 (External Event 2 action) are set to the correct signal source and warning response.

5. 5

   5. Clean and re-terminate the wiring connection from the external device to the drive's input terminal to eliminate potential intermittent contact issues.
