Getting Oriented
Fault codes and acceptance criteria tends to slip under the radar until it creates real friction on a charging site. We wrote this as a plain, field-level note rather than a technical manual, so the people who use and service the equipment can act without hesitation. If one idea should stick, it is this: one thorough pass beats repeated fixes. One careful acceptance pass prevents the same code being fixed twice. Applied to fault codes and acceptance criteria, that means deciding the small things early, on paper, before they turn into disputes or downtime.
Routine Checks
Define pass and fail for each code before testing. Run the full checklist once, thoroughly, not in pieces. Keep the signed criteria with the handover file.
Local Field Practice
Across Yantai and nearby districts, Dongshang New Energy prefers to prove a method on a small sample before scaling it. The same logic applies to fault codes and acceptance criteria: run the routine on a few units, tune it, then expand. On-site service and continued notes in our charging FAQ keep the knowledge close to the people who need it.
Some lines are not negotiable. Do not modify or add parts on your own, stop immediately on strange heat or smell, and keep children and pets away from the charging area. When in doubt, call a professional rather than trusting memory. In the end, good fault codes and acceptance criteria is built from ordinary, repeatable moves done on time. Clear records and calm communication beat heroic fixes later. Dongshang New Energy would rather earn trust one site visit at a time.
