TORQUE LIMITER CALIBRATION
•
Refer to the following illustration when carrying out the procedures described below.
7-1
Adjustment - Measured Value Over the Limit
•
If the measured value of maximum compression force is greater than the upper limit of 30 daN, pro-
ceed as follows:
1. Remove the set screw from the torque limiter (2 mm allen wrench).
2. Turn the adjusting nut
counter-clockwise
until the set screw hole coincides exactly with the next
hole in the lock washer underneath the adjusting nut.
3. Screw the set screw into its position in the adjusting nut, taking care to ensure that it enters the
hole in the lock washer. It must not exert pressure on the washer.
4. Repeat the check and adjustment procedures until the measured maximum compression force is
within the specification.
7-2
Adjustment - Measured Value Under the Limit
•
If the measured value of maximum compression force is less than the lower limit of 27 daN, proceed
as follows:
1. Remove the set screw from the torque limiter (2 mm allen wrench).
.
Turn the adjusting nut
clockwise
until the set screw hole coincides exactly with the next hole in
the lock washer underneath the adjusting nut.
2. Screw the set screw into its position in the adjusting nut, taking care to ensure that it enters the
hole in the lock washer. It must not exert pressure on the washer.
3. Repeat the check and adjustment procedures until the measured maximum compression force is
within the specification.
