Documentation from the manufacturer
Faults and fixes BMXFCW303
Problems with BMXFCW303: ERR LED on or program lost
On Modicon TSX Premium, M340 and Quantum a lit ERR LED indicates a processor or program fault; the diagnostics in Unity Pro or Control Expert name the cause. Older processors keep the program with a battery: a flat battery (BAT LED) erases it on a power loss. Always keep the project as a file or on the memory card as well.
What do I check when replacing a BMXFCW303?
Choose the same reference with the same or a higher firmware version so the project loads. Carry over the memory card, set the communication settings again (IP, Modbus address) and after loading check the I/O configuration against the rack.
Fault not fixed: replace, exchange or repair the BMXFCW303?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the BMXFCW303 refurbished (tested, with a test report per serial number) or new in factory packaging, with a 24-month warranty. The current lead time is shown with the condition on this page. Prefer an exchange: you get a refurbished unit straight away and return the faulty one within 14 days. Repairing your own unit is also possible: diagnosis, then a fixed price.
What information should I send for a quick diagnosis?
A photo of the rating plate (order number, product version, firmware), the exact fault code or LED state, when the fault occurs (at power-up, on enable, under load) and what you have already tried. For PLCs an export of the diagnostic buffer, for drives the parameter set. With that we can usually say the same day whether replacing, exchanging or repairing is best.
