Faults and fixes EMB9341-E
Problems with EMB9341-E: no 24 V, LED off or flashing
LED off: check the mains voltage and the input fuse. LED flashing or the output coming back briefly again and again: the supply is in overload protection (hiccup), usually because of a short circuit or too heavy a load on the 24 V side. Disconnect the load: if the 24 V returns, the fault is in the installation, not in the supply.
EMB9341-E: output voltage sags or ripple increases
A supply that sags under load after years or shows more ripple usually has aged electrolytic capacitors. This shows as sporadic CPU resets, modules reporting SF or panels restarting. Replacement is then the reliable remedy; a refurbishment replaces these capacitors and tests the supply under load.
Fault not fixed: replace, exchange or repair the EMB9341-E?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the EMB9341-E refurbished: tested to this family's test protocol, with a test report per serial number, 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.
