All LEDs at the frontside indicate the actual state. This is very helpful for the first diagnostic of the connected SMI drives.
1.- LED with arrow up flashes, drives are moving upwards.
2.- LED with arrow down flashes, drives are moving downwards.
3.- Both LED’s are off, intermediate position e.g. not in end position.
4.- Both LEDs quickly flash alternately, SMI communication fault, e.g. no drive is connected to this output or SMI data line is damaged.
5.- Both LEDs slowly flash alternately, Function Safety is active, e.g. wind alarm. Manual operation of this output is blocked as long as the alarm is active.
6.- Both LEDs flash simultaneously, Non-permissible number of SMI drives is connected.” More than 4 drives”
