Westfalia Separator PLC 100/3D 005-4050-280 PLC controller

The Westfalia Separator PLC 100/3 D (part 005‑4050‑280) is a 24 V DC programmable logic controller designed to manage centrifuge and separator operations such as bowl speed, timing, and discharge cycles. Common failure points for this model include degraded power supply modules, worn contactor contacts on the operational relay, and memory cassette corruption due to aging or vibration. Initial checks should verify that the 24 VDC input is stable within ±20 %, inspect the relay contacts for pitting or arcing, and review any stored error codes in the PLC’s diagnostic log before proceeding with component replacement.[oss-gpt-20b]
