D <strong>Series</strong> <strong>Syringe</strong> <strong>Pumps</strong><br />
Section 3 Single & Multiple Independent Pump Operation<br />
Note<br />
This screen is momentarily displayed automatically each time<br />
the pump controller is turned from STANDBY to ON.<br />
To display the status<br />
3.3.8 External Analog<br />
Control<br />
Setting up external control<br />
1. Press the MENU key and then press softkey A, MORE.<br />
2. Press 2 to display the pump status.<br />
3. The first line displays the revision of the software.<br />
4. Lines 2, 3, and 4 display the type of pump connected to the<br />
A, B, and C pump connectors, respectively.<br />
The D <strong>Series</strong> syringe pump can be controlled externally by<br />
analog voltage in either constant flow or constant pressure mode.<br />
The input range is 0 – 11.5 volts (for all pumps), with a resolution<br />
of 5000 increments per volt.<br />
1. Select the desired operating mode (CONST FLOW or<br />
CONST control: PRESS) by pressing the appropriate key<br />
on the controller front panel.<br />
The mode you have selected, along with the current pump<br />
will be displayed in the upper left-hand corner of the<br />
screen. For example, if you have selected CONST PRESS,<br />
CP will be displayed, followed by a lowercase a, b, or c<br />
depending on the selected pump.<br />
To set parameters for a different pump, press softkey D,<br />
SELECT PUMP, and choose A for pump A, B for pump B,<br />
etc. Once you have changed pumps, the display will change<br />
back to the run screen, automatically.<br />
If you do not wish to select a different pump, press softkey<br />
D to return to the run screen.<br />
2. Press MENU, then softkey A for MORE options.<br />
3. Press number key 3 to select EXTERNAL control.<br />
4. Softkey B will toggle the EXTERNAL mode ON or OFF.<br />
5. If you wish to change the full-scale input voltage, press softkey<br />
A to SET RANGE. Then enter the new voltage range<br />
between 1.000 V and 11.500 V, and press ENTER to store<br />
the value. This voltage will correspond to the maximum<br />
flow rate or pressure value programmed by the LIMITS key.<br />
DV FS<br />
ML = input<br />
where:<br />
DV = desired value of pressure or flow rate.<br />
FS = full-scale input range.<br />
ML = max limit of pressure or flow rate<br />
input = external input voltage.<br />
