OTIUM E3-ST Standard
The spring load rating of the „ST60N“ („or ST90N“) is determined such that a door with a maximum door weight of 25 kg (or 50 kg for the ST90N) can be cycled up to 40 000 times, with the damper still functioning as per specification. Adjusting the variable set screw has no effect on the closing of the door, but only regulates the damping strength (force).
On request, springs with a higher force rating (closing capacity) can be supplied as an extra.
The spring load ratings vary with ± 2 N. Opening force is measured at 130 mm.
The screw must not be rotated/adjusted too far!
