CAUTION
●
Increasing the preset torque will cause the torque limiter to function at a torque value that exceeds the initial setpoint. Damage
to the machine may occur.
12-1 Adjusting Preset Torque for the Spring-Loaded Limit Switch Model
• The preset torque is shown at the center of the adjusting scale plate [1] in the figure below.
Torque values indicated by T1 and T2 are positioned at ± 150° from the center. Use T1 and T2 as points of reference when changing
the preset torque.
• When it is necessary to increase or decrease the original preset torque, use the adjustment bolt [2].
Adjust torque within a range of ± 25% of the preset torque.
Overscaling T1 and T2 is permitted within ± 25%. However, do not make adjustment in excess of the maximum preset torque. (See
the selection table in the catalog.)
• An index [4] is stamped in the cut on the side of the threaded section of the adjustment bolt [2]. The index [4] is aligned with the
end face of the case cover [3] when the mark [5] on the adjusting bolt [2] is located at the position of the preset torque on the
adjusting scale plate [1]. Make fine adjustments using this alignment as a base. If the adjustment bolt is too tight or too loose, first
reset the adjustment bolt to align the index [4] with the end face of the case cover [3]. Then make adjustments.
