Configuring For Devices Without Contacts
Edit the current configuration parameters by opening the configuration dialog. See
Editing The Configuration, above, for details. Select the Contacts tab at the top of the
dialog. Be sure the Contact Type is set to “None” (Figure 12). This will disable all
contact testing.
Choose the Test Time tab. Set the maximum up and down times based on the test
criteria. The cylinder air pressure, flow rate and stroke length all affect the test time. Also
required is extra time for the LCTS to dwell at the motion extremes. The user must
determine the up and down stroke times based on the item to be tested. The Maximum
stroke times must be limited to a range of 0.025 to 5.000 seconds each. Thus the fastest
test time is 0.050 seconds or 20 cycles/sec. The slowest is 0.1 cycles/sec.
The minimum stroke times must be limited to the same range as the maximum. Though
these parameters are not applicable to non-contact testing, they are still verified (as are
all configuration parameters). By definition, the minimum time must be less than the
maximum time. Thus, for a non-contact device, it is easiest to set both minimum stroke
times to 0.025 seconds.
Choose the Limits tab on the configuration dialog box. Enter the number of Test Cycles
to perform on the tested device. The minimum limits are 1 and maximum are 10,000,000.
Since a non-contact device can’t fail, the Maximum Test Failures and Maximum
Sequential Failures settings are irrelevant, but must be in the same range for limits.
Click the OK button to transfer the parameters.
