Control Unit Display
➀
The 2-digit, 7 segment LED will display: day-counts, RESET-TEST touch-button diagnostic codes,
and
possibly
Diagnostic Codes Between 0.2 Gph Test-cycles
when the system is operating
normally. The display will also rapidly flash: line leak detected / test-fail alarm codes, monthly-
compliance warning codes, or error codes when faults occur.
Normal Displays
( on steady / solid )
Day Counts
Ordinarily, the display shows the total number of days since the last 0.2 gph
monthly-compliance test passed. The
day count
is on steady (not flashing) and
advances one day for every 24 hours that a monthly test does not finish with a
passed result. The normal display range is from
00
(zero days) to
28
days, i.e.
00
= zero days (a 0.2 gph test has passed within the last 24 hours), up to
28
= twenty eight days have elapsed since the last monthly-compliance test
passed (also see Monthly-Compliance Warning which begins on Day # 29)
Fault Displays
( rapidly Flashing – twice per second )
Alarms, Warnings, and Error codes, ranging from
80
to
85
, are displayed when the
following conditions occur.
