F233

External power supply error

Indramat · DIAX 04

What does F233 mean?

The DIAX04 SSE-03VRS drive has detected an error with an external power supply, typically the 24VDC control voltage. This supply is critical for the drive's control electronics, I/O, and safety circuits. A fault here can lead to unstable operation, loss of control, or failure of external devices powered by this supply.

Common Causes

  • The external 24VDC power supply feeding the DIAX04 SSE-03VRS control section has failed, is overloaded, or its output voltage is too low.
  • Wiring from the external power supply to the DIAX04 SSE-03VRS control terminals is disconnected or damaged.
  • Short circuit or excessive current draw on the 24VDC output from the DIAX04 SSE-03VRS or associated external devices.
  • Fuse protecting the external 24VDC supply circuit has blown.
  • Loss of incoming AC supply to the external 24VDC power supply.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Measure the voltage of the external power supply (e.g., 24VDC) at the input terminals of the DIAX04 SSE-03VRS. Verify it is stable and within tolerance.

  2. 2

    Check the wiring and connections from the external power supply to the DIAX04 SSE-03VRS for looseness, damage, or correct polarity.

  3. 3

    Inspect for any short circuits or overloads on the 24VDC circuit, including any devices powered by this supply.

  4. 4

    Verify the status of fuses and circuit breakers associated with the external power supply.

  5. 5

    If the external supply is confirmed good, investigate the DIAX04 SSE-03VRS internal control voltage monitoring circuit for a fault.
