EXAMPLE: Retrieved data is; ADD = (no display), DETERGENT = 2, SANITIZER = 07, RINSE = 30, AID = 76
1. Disregard ADD since there is no numeric display.
2. Multiply 2 x 1,000,000 (DETERGENT) = 2,000,000
3. Multiply 07 x 10,000 (SANITIZER) = 70,000
4. Multiplier 30 x 100 (RINSE) = 3000
5. Multiply 76 x 1 (AID) = 76
6. Add products together to obtain total cycle count.
Total Cycles = 2,000,000 + 70,000 + 3000 + 76
Total Cycles = 2,073,076
OUTPUT TESTS
CLOSE DOOR BEFORE
BEGINNING OUTPUT TEST. KEEP DOOR CLOSED
DURING TEST.
The output test cycles the relay outputs ON and OFF.
The output is ON for 5 seconds, then OFF for 25
seconds. The display alternates between flashing the
output number chosen and [ On ] for five seconds
when the output is energized. When the output is de-
energized, the display will alternate between the
output number chosen and the remaining off time
(count down) in seconds. The output test continues for
the same output number until ª (arrow) or SELECT is
chosen.
