Static Shear Tester Operating Instructions (SS-RT-10, SS-HT-8, SS-HT-30)
3. Thirty bank oven units: Lay the switch bank on its back. Remove the base of the
unit. This allows access to the switches. Loosen the screws holding the wires,
and then remove the screws holding the switches in place using a 5/64" Allen
key. After bending the lever on the new switch (See Below - "D"), install the new
switch. Make sure the wires are connected to the proper terminals, and then
replace the base.
B. To adjust spring tension: Using a 9/64" Allen key, turn screw clockwise to increase
tension. Turn screw counter-clockwise to decrease tension. [NOTE: Increasing
tension will raise the Trip Plate from the switch lever, making it necessary to use
heavier weights to trip the switch. Decreasing the tension will have the opposite
effect.] (See Figure A
– Trip Plate)
C. To bend switch lever: Using a 9/64" Allen key, remove both screws with springs and
lift off landing platform. Press down near the rear of the lever while bending up the
front end. To test if it has been bent correctly, install the landing platform and
screws, and then set a weight on the panel. If the weight trips the switch, the lever
has been bent correctly. This procedure may have to be repeated until the lever is
adjusted properly. (See Figure B
– Lever Adjustment)
