Pump
level : - in pump down, the function goes on when the level rises
to the ON setpoint and goes off when the level lowers to the
OFF setpoint. In pump up, the function goes on when
the level lowers to the ON setpoint and goes off when the
level rises to the OFF setpoint.
sequential : - refer to Applications\Pump Control. Select function option 8, 9 or 10
and press "*" to scroll through the loss of echo defaults.
For option 9, pressing "*" will also scroll through the cumulative,
ratio or duty/back-up mode of pump up operation.
differential : - the pump down function goes on when differential
level increases to the ON setpoint and goes off when the
differential level decreases to OFF setpoint. The pump up
function goes on when the differential level decreases
to the ON setpoint and goes off when the differential level
increases to the OFF setpoint.
