When I put my light into a dynamic mode (like cloud cover or storms), it blinks

If your light is in any dynamic mode such as cloud cover or storm mode, the ramp and dim function cannot be used.  The ramp/dim and dynamic mode will conflict with each other and cause the light to blink.  If this occurs, simply put your timer in F2 Mode or wait for the ramp/dim to end this will not harm the light).
