There are two modes available for cyclic lighting: Sequential and Concurrent . Sequential is when one light bank comes on at a time. Concurrent is when they all come on at the same time. The Start Delay is at the beginning of the cycle and the Finish delay occurs at the end. See diagram below. The Min On Time is the shortest time that the lights will be on. This is to eliminate “short cycling” of the lights. The figure below illustrates the case where you selected the sequential mode and you have two light banks. The start delay is at the beginning of the cycle. (Each light bank is programmed separately as to the time window for the light bank to be enabled and the on time for each light bank. The Start delay occurs at the beginning of the cycle and the Finish delay at the end.
