Currently we are facing serious issue in our control system. Secondary air fan is equipped with seismic vibration in each bearing. The problem is whenever we start work in field in any transmitter which is not related with this vibration, we observed spikes in vibration probes in our control system. The common thing between any transmitter and this vibration probe is only DCS, and all other thing have no any relation like JB, cable and as well as far from each other. Please advice what is the possible reason of this spikes.
Urgent response will be highly appreciated.
