1.5 Switch Adjustment

Note: The switch is factory adjusted to open after the stem has traveled .025" in the axial direction.

Adjustments should only be made if replacing the switch.

1. De‑energize all electrical and pneumatic power supplied to the Collision Sensor. Drain all stored air and

electric power in compliance with standard (OSHA) safety practices and standards.

2. Disconnect the air lines and signal wires connected to the Collision Sensor.

3. Remove the user‑installed mounting hardware from the Collision Sensor and remove the unit. Take the

unit to a test bench equipped with a clean working surface and compressed air.

4. Insure that the Collision Sensor returns to its Reset or Working position with the stem fully extended and

the alignment mark on the stem in line with the alignment mark on the cover plate (Temporarily supply

approx. 15 psi (1 bar) to the unit unless equipped with a preload spring.)

5. Connect a test box per

6. Attach an interface plate to the stem of the Collision Sensor.

7. Center the Collision Sensor under the press ram (see

8. Set a dial indicator in contact with the interface plate and adjust it so that the probe is vertical. Set the

dial indicator height so that it can read at least .06" (1.5 mm) stroke. Set the dial ring to zero.

9. Push on the press handle until the switch circuit opens and check the distance traveled on the

dial indicator.

10. If the distance traveled is greater than desired turn the adjustment screw counterclockwise. If the distance

traveled is less turn the proximity switch clockwise.

11. Repeat steps (9) and (10) as necessary to obtain the desired switch setting.

12. Re‑install the Collision Sensor using the user‑installed mounting hardware.

CAUTION: Before putting the Collision Sensor back into operation, confirm that the

switch is functioning properly. See
