Occlusion Release
Occ Rel: “Occ Rel” stands for occlusion release and is typically used to
test a product in which an unobstructed flow is expected; yet the product
could occasionally be blocked (occluded).
The occlusion release option is available only in testers that have the
occlusion test capability. Occlusion release is used to open a product to
atmosphere during the test phase. This allows Sprint LC to read the gross
pressure drop expected on products that have no obstruction.
Occlusion release can be set to YES (active), or NO (inactive) by using the
INCREMENT and DECREMENT keypads. When Occlusion Release is set to
YES, the valve opens (activates) as normal in the fill and stabilize times.
The coupling then closes (de-activates) at the start of test time.
Hold on Failure
Hld / Fail: “Hld / Fail” stands for hold on failure. The purpose of the hold
on failure function is to make certain the operator acknowledges a failure
and dispenses with the failed product. Hld/Fail can be set to either YES
(active) or NO (inactive) by using the INCREMENT and DECREMENT
keypads. A time value is not entered. If set to YES, and the test fails, all
enabled coupling valves remain activated (to hold the product) and will
not reset until the white START switch is pressed. At the end of a failed
test, the word HOLD is displayed in the status box. The red fail light and
the alert tone remain on. The white START switch must be pressed to
conduct another test.
CAUTION
Hold on Fail will maintain (energize) all coupling
valves until a start signal is received. DO NOT
allow a Sprint LC tester to remain in a hold
condition for more than 15 minutes.
If Hld/Fail is set to YES and no coupling valves are active, the tester will
wait for the reset signal from the START switch, but the coupling will not
be active.
