Specification and adjustment CONCEALED DOOR CLOSERS Speed adjustment range There are two speed ranges for door closing speed. Those ranges are classified into two stages of the st speed range which controls general door closing speed and the 2nd speed range which controls closing speed. Those speeds can be adjusted independently. Closing time from the door opened at 90 degrees is appropriately 5 to seconds. (Set the 2nd speed slightly slower than the st speed.) Latching action range 2nd speed range st speed range Latching action function (COU-52,5 CO-55,5) Door can be closed by the latching action function to quickly close in 2 degrees before closing position.
