Question

My DL105 drops out of run mode intermittently. What's wrong?

Answer

This problem occurs only with the relay output version of the DL105. If the relay is driving an inductive load, the load needs to be suppressed using any MOV or TVS. This prevents EMF (noise) from traveling back to the relay and will keep the DL105 from dropping out of run mode.

Please see AN-MISC-032 for information on correcting relay transient issue.
