6.3 Mode 1 - Manually adjusting the output - In this mode, the pump
is turned on and off by an electronic cycle timer. The pump will energize for
the duration of the “on time” and de-energize for the remainder of the “total
time” thus completing one cycle. The cycle then repeats.
The “on time” and “total time” cycles are independently adjustable from 0.1
to 199.9 units of measure with a 0.1 unit resolution. The units of measure
can be seconds, minutes, hours or days.
Example: If the “total time” cycle is adjusted for 90 seconds and the “on
time” portion of the cycle is adjusted for 5 seconds, the pump will run for 5
seconds and turn off for 85 seconds (90 second total cycle). This cycle is
repeated until either the standby button is pressed, the cycle time is changed
or the input power is disconnected from the pump.
