Drop-Probe Device
INSTALLING THE DROP-PROBE ASSEMBLY, PVC INSULATOR BLOCK, AND SENSING PROBE
1. Loosely connect the PVC insulator block to the end of the cylinder rod on the bottom of the drop-probe box. Do not tighten all the way at
this time.
2. Determine vertical or horizontal placement of the drop-probe box. Keep in mind that horizontal mounting will result in the 1” x 2” extrusion
being mounted on the bottom rear of the drop-probe box. Mount the extrusion to the drop-probe box. (See photo below, left.)
NOTE:
For welder applications, do not
mount the drop-probe box parallel to the upper armature plane. Fabricate a mounting bracket that will
attach to the welder frame and run parallel to the bottom stationary armature instead. Mount the drop-probe box to this fabricated bracket.
For riveter applications
, make sure the drop-probe box is mounted parallel to the vertical plane of the top riveting punch.
3. While holding the drop-probe box with the extrusion to the mounting spot on the machine, angle the PVC insulator block towards the work
surface. Make sure the air cylinder rod is fully retracted (up).
4. Secure the drop-probe box assembly to the machine (as close to the work surface as possible).
NOTE: The sensing probe will add additional height to the overall mounting dimensions. If necessary, the PVC insulator block may be shortened
by cutting off the first (outer) position where the sensing probe slides into the PVC block. Do not cut off the third hole between the outer and inner
sensing probe mounting holes—the probe will not be able to be clamped tight!
5. Choose the sensing probe that best suits your application. (See example of sensing probe in photo below, right.) Shape (if using the aluminum
probe) and install the sensing probe. To position the sensing probe, loosen the screw on the down stop locking collar and position the sensing
probe so it is 1⁄4” or less above the point of operation. Tighten the screw on the lock collar.
6. Tie off all wires and air tubes when finished so they do not come in contact with the adjustable down stop locking collar on the air cylinder.
