Function

Cancel Key

Pressing Cancel will clear an entry that has
been input with either the arrow or soft keys.
If no entry has been made, the previous
window will be displayed. This allows
passage through the windows in the reverse
direction.

Run/Stop Key

This key is used to start or stop the pump in
both Manual mode and Program mode
operation. The pump will run in the clockwise
direction by factory default. The green and
red LEDs are illuminated when the Econo
Gradient Pump is running or stopped,
respectively. The direction can be changed
using the Reverse Direction key, when the
pump is stopped.

Reverse Direction Key

This key changes the direction of pump
head rotation. The Econo Gradient Pump
must be stopped before the direction can be
changed. This key is not operable when the
pump is running. The yellow and orange
LEDs are illuminated when the pump is
running clockwise (CC) and counter-
clockwise (CCW), respectively.
