SECTION 3—POWER-UP PROCEDURES
Adjustable Stroke Detect-A-Finger
®
Drop-Probe Device
Power-Up Procedures
1. Turn the main electrical power and the main air valve to the machine on.
2. On the mini filter-regulator assembly, set the air pressure on the left regulator to about 15 PSI and the right regulator to 0. The air cylinder
in the drop-probe assembly should be fully retracted (up). If the air cylinder is not in the retracted position, turn off the air supply and
reverse the two air tubes going into the air bulkheads on the outside of the control box. Turn the air supply back on and verify the air
cylinder is in the up position.
3. Actuate the foot switch. The machine should not cycle at this time. If the machine cycles unexpectedly, verify the air pressure on the
right regulator is turned all the way off and that the air cylinder in the drop-probe assembly is in the up position. If the air cylinder in
the drop-probe assembly does not move when the foot switch is actuated, recheck all wiring and air connections. Correct any
mistakes before proceeding.
4. While actuating the foot switch (and the machine not cycling), slowly increase the air pressure on the right regulator of the mini filter
regulator assembly until the air cylinder extends. The machine should cycle at this time.
NOTE:
For welder applications,
the sensing probe should extend down to the preset stop position and then immediately return to top.
For riveter applications,
the sensing probe should extend down to the preset stop position and remain down through the entire
machine cycle.
5. Verify that all is functioning correctly and then adjust the air pressure on the left and right regulators to increase the speed of air cylinder
operation.
Use small increments when adjusting the regulators.
Always try to use the least amount of air pressure on the drop-probe assembly air cylinder. Excessive air
pressure could cause the sensor wire to bend out of shape.
6. Insert the workpiece into the machine and actuate the foot switch. Verify that the sensing probe is stopping at the mandatory 1⁄4” above
the point of operation. Make adjustments to the lock collar if necessary.
7. After all adjustments are made, verify that the Detect-A-Finger® drop-probe device is working properly. Place an inanimate object—
NOT A FINGER
—between the workpiece and sensing probe. Actuate the foot switch and verify that the machine does not cycle.
Do not use a finger as a test object—always use an inanimate object. Do not place the test object under the moving part
of the machine.
8. When verification is complete, you are now ready for production.
CAUTION
Proceed with caution when performing the power-up procedures. The machine may cycle unexpectedly.
