D Series Syringe Pumps
Section 3 Basic Programming and Operation

3. The controller will display maximum flow rate and target
pressure setting. If these values are correct, press D to con-
tinue rapid pressurization.
4. If you know approximately what the pressure will be when
the system is stable, enter this value as a target pressure.
Press A and enter the desired pressure value. This should
shorten the time required to stabilize the system pressure.
5. If you would like to limit the maximum flow rate during
the rapid pressurization phase, press B and enter the
desired flow rate limit.
6. Press D to continue rapid pressurization.
3.8.9 DISP The DISP key activates Dispense Mode, for applications such as
reactant feed and batch delivery, where a specified volume is
pumped. Refer to Section 3.10.3 for programming steps.
3.8.10 ACC CTRL The ACC CONTROL key will allow you to manually operate
accessories, such as valves, via the Digital Output terminals on
the back of the controller.
1. Press ACC CTRL.
2. From the accessory control menu, use the number keys 1-8
(1-A INLET, 2-A OUTLET, 3-B INLET, 4-B OUTLET, 5-C
INLET, 6-C OUTLET, 7- D INLET, 8- D OUTLET) to toggle
the desired valve open or closed. (Numbers 1-8 represent
digital output terminals 1-8, respectively).
3. To exit, press PREVIOUS (D).
3.8.11 ZERO PRESS The ZERO PRESSURE key will correct pressure sensor drift.
Before pressing ZERO PRESS, the pump should have port fit-
tings installed, and be depressurized.
1. Press ZERO PRESS. The display will show the current
pressure and ask if you want to zero the pressure.
2. Press A, B, C, or D to zero the desired pump.
or,
If the pump is not depressurized, press DO_NOT (D) to exit
the zero pressure operation. If four pumps are connected
press the STORE,RECALL OR CLEAR ENTRY key.
3.9 Control of Multiple
Pumps
When using multiple pumps, there are four multi-pump oper-
ating modes of delivery and one independent mode:
• Continuous flow in constant flow mode.
• Continuous flow in constant pressure mode.
• Modifier addition in constant pressure mode.
• Modifier addition in continuous flow, constant pressure
mode.
• Independent mode.
