I was able to track down the for this Diagnostics Parameter D345 use 600000 for off time (600sec) and D350 use 30000 for on time (30sec).
For a tests we entered 30000 into the Diagnostics Parameter D345 and D350 and we could feel the relay turning on and of every 30sec. (FYI, these parameters were blank.)
We changed D345 to the value proper value given 600000 (10min) and issues was solved.
