Error in small time step

["Piya Louis Siangsukone" <Piya.Siangsukone@xxxxxxxxxxxxxxxxx>]

Dear TRNSYS users,

I have a problem when I run TRNSYS with small time step (0.1-0.5 minutes). After investigation, I found it the
problem occurs from the Radiation Processor Type 16h with the time step less than 0.6 minute. 
Without the radiation processor, I can run my project with any time step I would like.

The error message is Range Check Error.

How can I run the project included radiation processor with a small time step?
Have anyone encountered this problem?

Thank you for your help,
Louis
