5.6.2 Program Entry Mode
While the Pumping Program is stopped, “Program Entry Mode” can be entered by pressing and holding the ‘Rate’
key. Release the key when the display shows the current Program Phase number:
nn
, where ‘nn’
indicates the current Program Phase number.
With the current Program Phase number displayed, if the currently selected Program Phase is set to a pumping rate
function, a momentary press of this key will exit “Program Entry Mode” and return to the rate display.
5.7 ‘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.
With the Pumping Program stopped, and the “Volume to be Dispensed” displayed, pressing the arrow keys will
change the “Volume to be Dispensed” (see sec. 5.4, Arrow and Decimal Point Key). The units of the volume are
set according to the syringe diameter, but can be changed. The new “Volume to be Dispensed” is stored in the
current Program Phase. If the “Volume to be Dispensed” is disabled (“off”), pressing any up arrow key will
change the display to 0.0. The “Volume to be Dispensed” can now be set using the up arrow keys.
While pumping, pressing this key will switch between displaying the current “Volume Dispensed” and “Volume to
be Dispensed”.
5.7.1 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.
5.7.2 Clearing “Volume Dispensed”
With the Pumping Program stopped, display the “Volume Dispensed”. Pressing and holding any up arrow key for
one second will reset the infusion and withdrawal dispensed volumes to 0.
5.7.3 Program Entry Mode
“Program Entry Mode” is entered by pressing and holding the ‘Volume’ key. Release the key when the display
shows the currently selected Program Phase’s function.
In “Program Entry Mode”, when the Program Function is not displayed, momentarily pressing this key will display
the current Program Function.
When the Program Function is displayed, if the function is a pumping rate function, “Program Entry Mode” can be
exited by momentarily pressing the ‘Volume’ key. The display will show the “Volume to be Dispensed”.
Otherwise, pressing the ‘Volume’ key will display the “Volume Dispensed”. Pressing the ‘Volume’ key again will
return to displaying the Program Function.
5.8 Pumping Direction Key
The pumping direction key, ‘ ’, changes the direction of pumping. Pressing this key switches the pumping
direction between ‘infuse’ and ‘withdraw’, as indicated by the ‘Withdraw’ LED. When the LED is lit, the pumping
direction is ‘withdraw’, not-lit, pumping direction is ‘infuse’, blinking indicates “Sticky Direction” is set. The new
pumping direction is stored in the current Program Phase.
The “Volume Dispensed” is accumulated separately for infusion and withdrawal. When the pumping direction is
changed, the current “Volume Dispensed” is also changed accordingly between the infusion and withdrawal
“Volume Dispensed” accumulations.
When the Pumping Program is operating and the “Volume to be Dispensed” is non-zero, the pumping direction
cannot be changed. Otherwise, when pumping continuously (“Volume to be Dispensed” disabled), the pumping
direction can be changed.
5.8.1 Sticky Direction
With the pump stopped, press and hold the direction key to set “Sticky Direction”. The LED will blink when set.
“Sticky Direction” will continue the pumping direction of the previous Pumping Phase or, if the first Phase, set the
pumping direction according to the logic level of the “Pumping Direction” TTL input pin (pin 3):
Direction Control: Reciprocating Pumps (dr:rE) Dual Pumps (dr:dU)
Low Level: Infuse Withdraw
