Annual (0.1 GPH) Leak Test
When the line has been inactive for 6 hours, an annual (0.1 GPH) test is initiated.
This test will be performed every 5 minutes until a test has passed. If there are
three consecutive failures, with no passes, the ALARM light will flash, and the
HORN will sound, indicating that there is a precision leak in the system. This
ALARM indication will not shut down the pump.
Silence Alarms
Before pushing the Test/reset button take note of the displayed Alarm conditon, see
chapter 6 troubleshooting section. Some alarm conditions will not clear until the
detected conditon is corrected (i.e. transducer not seen).
Push the Test/Reset button on console for the Line with an active, blinking or
flashing Alarm light. When the Test/Reset button is released the alarm is cleared.
The audible alarm will silence and the Alarm light will stop blinking or flashing, and
the line test will continue its normal testing procedures. The Monthly (0.2 gph/
0.75 Lph) tests will automatically restart after 3 hours of inactive time, and the
annual (0.1 gph/0.38 Lph) test will automatically restart after 6 hours of
inactive time. DO NOT restart precision line leak tests before the 3 or 6 hour
no-dispense stabilization-time has passed.
MANUAL Line Leak Tests
Leak tests may be manually started at any time. The Monthly (0.2 gph) leak test
requires 3 hours of inactive time to insure a valid test. The Annual (0.1 gph) leak
tests requires 6 hours of inactive time to insure a valid test. Not waiting the
required inactive time means a passed or failed test is inconclusive.
Gross (3 gph /11 Lph) test: Press and release the Test/Reset button as if clearing
alarms (see above) wait for the TEST lamp to turn on then press and release the
Test/Reset button again (2 Test/Reset pushbutton presses). The Pump will turn on
for 5 to 10 seconds to pressurize the line, and testing will begin. A single PASS or
three consecutive FAILURES are required to complete the Gross (3 GPH) test. In
between these tests, lamps will indicate whether the last test passed or failed. A
PASS will put Auto-Learn back into normal DETECT mode, with indicator lamps in
the OFF condition. Three consecutive FAILURES will put Auto-Learn in alarm
condition, and provide positive shut-down of the pump.
Monthly (0.2 gph/ 0.75 Lph) test: To initiate a monthly (0.2 gph) test press and
release the Test/Reset button as if clearing alarms and wait for the TEST lamp to
turn on then press and release the Test/Reset button again. Press and release the
Test/Reset button a third time when the TEST lamp turns on (3 Test/Reset
pushbutton presses). The Pump will turn on for 5 to 10 seconds to pressurize the
line, and testing will begin. A single PASS or three consecutive FAILURES are
