of electric positioning should be 60 seconds, after which it will return to the normal
situation. If the setting fails within 60 seconds, please repeat the following steps:

2. Upper/Lower Limitation Adjustment (Hard Limits)
Upper limitation and lower limitation are preset in the factory. The upper limitation
should be a little higher than ceiling height. Lower limitation is showed as numerical value
D in the specification table (the upper/lower limitation for sling wire should be regulated
by professional people or dealers. Improper regulation carries safety risks).
