Ok well it depends on the manufacturer to what the lights mean and there are so many copies of the DM drives it's hard to know. The original Lead shine DM drives use 3s time periods. So if red light flashes 1 x in 3s=over current protection. 2 x in 3s = Over voltage protection. 4 x in 3s= phase error (wired wrong)

So count the muber of flashes in that tme period. Also post some good pics of how you have it wired.
