Had an interesting conversation with one of our burner manufacturer’s service engineers today regarding the use of reset mechanisms.
We were investigating the possibility of enabling a setting on a set of burners that would enable being able to reset their control units following a fault through a communications channel (Modbus in this case) rather than by a currently hard-wired circuit. He stated that the manufacturer had claimed that such a reset mechanism would violate regulations (somewhere) and that a remote reset like it was therefore prohibited. He went on to say that the setting documented in our literature didn’t even exist or was inaccessible. The burners and their managers are manufactured in Germany, but we install, commission, and integrate them into automated systems all over the place.
Am I wrong in thinking that, in literal and practical senses, anything beyond the unit’s HIM would constitute a remote reset, including the existing reset circuit already in-place? We are able to activate/deactivate heat and transmit setpoint over comms without issue. The burners alone also don’t ship with high-temp controllers, so we supply and integrate them in series with the safety circuit. They require a manual reset when tripped.
What makes the burner reset get this kind of attention?
Anyone else run into this topic before?
