6.7.1 Pumping Rate Units
The pumping rate units can only be changed when the Pumping Program is not operating. If the currently
selected function allows selection of rate units (‘RATE’ function), a momentary press of the ‘Rate’ key
will enter Rate Units Change mode. The 2 LEDs representing the units will blink and the display will
show: .
Each press of any arrow key selects the next rate units, as indicated by the blinking units LEDs. When the
required rate units are blinking, press any non-arrow key or wait 2 seconds. The display will blink,
indicating the rate units are stored. The rate units are stored in the currently selected Program Phase. The
rate units can be independently set for each Phase with a ‘RATE’ function.
6.7.2 Program Entry Mode or Dispense Selection
While the Pumping Program is stopped, pressing and holding the ‘Rate’ key will enter “Program Entry
Mode” or “Dispense Selection Mode”.
If Dispense mode is enabled, the display will show the currently select dispense:
nn
Otherwise, the current Program Phase number is displayed:
nn
‘nn’ indicates the currently selected dispense or Program Phase.
A momentary press of the Rate or Volume key will exit return to the rate or volume display.
6.8 ‘Volume’ and ‘Program Function’ Key
When the Pumping Program is stopped, except in “Program Entry Mode”, momentary presses of this key
will switch the display between the “Volume to be Dispensed” and the “Volume Dispensed” displays, as
indicted by the ‘Dispensed’ LED.
While display “Volume to be Dispensed”, use the up arrow keys to enter a new value. Enter 0.0 to disable
the “Volume to be Dispensed” for continuous pumping. The new value is stored in the current Program
Phase or selected dispense.
If the “Volume to be Dispensed” is disabled, pressing any arrow key will change the display to 0.0. The
“Volume to be Dispensed” can now be set using the arrow keys.
While pumping, pressing and holding this key will display the current “Volume to be Dispensed”.
6.8.1 Disabling “Volume to be Dispensed”
To disable the “Volume to be Dispensed”, i.e. continuous pumping, set the “Volume to be Dispensed” to
0.0. After being stored, the display will show , indicating the “Volume to be Dispensed” is
off. In this mode, the pump will not stop at a set volume and will pump continuously until the pump is
stopped, or an “event trigger”, programmed into the Pumping Program, occurs.
