I installed a soft starter on a feed blender for a farm supply store about 2 years ago, it has worked flawlessly until now. It is a Stellar SR44-174 soft starter. After it has been idle for several hours, when a run command is sent to it, it will spool the motor up to speed then drop out and let the motor coast to a stop. Another run command will get the same result. The run is latched on external to the drive by an ice cube relay, I have checked this relay and it is holding in as it is supposed to. While in this condition I can shut off the control power for 15 seconds(resetting the starter) and it will operate as normal, until it sits idle again for several hours. Any body have experience with these drives? Any ideas?
