tie-down device asserts the input for the duration of the coupling time (or
times if there are multiple couplings). The intent is to keep the operator’s
hands safely on the anti-tie-down device and away from pinch points while
the fixture is moving to close and seal on the test part. The test cycle is
aborted if the anti-tie-down device releases the Remote Start input before
the coupling time(s) have completed. Also, Remote Stop can optionally be
used to abort the test cycle at any time. The Remote Start Enable input is
not used for this start policy and is ignored.
• Interlock: The Remote Start input starts the test cycle, if Remote Start
Enable is already asserted. Typically, Remote Start Enable is connected to a
test fixture interlock switch that indicates when it is safe to test. After this
condition is attained, some user action is required that asserts the Remote
Start input thus starting the test cycle. If Remote Start Enable is released
before the test cycle has finished, the test cycle is aborted. Also, Remote
Stop can optionally be used to abort the test cycle at any time.
• Barcode: The tester will start when a barcode is scanned.
Pass End-of-Cycle Action
Choose from:
• Normal
• Auto Repeat
• Continuous Fill
The Continuous Fill option found in the end-of-cycle actions is used to maintain
air pressure at the part as an aid in locating a leak.
