D <strong>Series</strong> <strong>Syringe</strong> <strong>Pumps</strong><br />
Section 3 Single & Multiple Independent Pump Operation<br />
Pressure Example<br />
The maximum pressure desired is 510.2 ATM, (maximum<br />
allowed by the MODEL 260D) with a scale factor of 2.0 volts per<br />
100 ATM. The full-scale input voltage would be:<br />
510.2 ATM <br />
2.00 V<br />
= 10.204 volts<br />
100 ATM<br />
and MAX PRESS should be set to 510.2 ATM.<br />
Maximum Flow Rate<br />
Example<br />
The maximum flow rate desired is 25.0 ml/min with a scale factor<br />
of 5.0 volts per 20.0 ml/min. The full scale input voltage would be:<br />
5.0 V<br />
25.0 ml/min <br />
= 6.250 volts<br />
20.0 ml/min<br />
and MAX FLOW should be set to 25.0 ml/min.<br />
Wire Connections<br />
Two wires are required for analog control. The analog common or<br />
ground wire should be connected to the GND terminal under<br />
ANALOG INPUT of the ACCESSORY connector on the controller<br />
rear panel. The analog control or input wire should be connected<br />
to terminal 1 under ANALOG INPUT.<br />
If two pumps are used with the controller, the second analog<br />
control or input wire should be connected to terminal 2 under<br />
ANALOG INPUT. If three pumps are used with the controller,<br />
the third analog control or input wire should be connected to terminal<br />
3 under ANALOG INPUT or to auxiliary (P11) pin 15.<br />
When using one of the multi-pump operation modes, only the<br />
ANALOG INPUT terminal 1 needs to be connected.<br />
3.3.9 Multi-Pump When using multiple pumps, there are four multi-pump operating<br />
modes of delivery and an independent mode, including:<br />
• Continuous flow in constant flow mode.<br />
• Continuous flow in constant pressure mode.<br />
• Modifier addition in constant pressure mode.<br />
• Modifier addition in continuous flow, constant pressure<br />
mode.<br />
• Independent mode.<br />
Continuous Flow (constant<br />
flow mode)<br />
A D <strong>Series</strong> continuous flow pumping system in constant flow<br />
mode, will consist of two syringe pumps and a valve accessory<br />
package, all regulated by one controller.<br />
To connect two D <strong>Series</strong> pumps for a continuous flow pumping<br />
system, you will need a continuous flow check valve package (P/N<br />
68-1247-059) or a continuous flow air driven valve package (P/N<br />
68-1247-129 for 65D, 68-1247-058 for 100D/260D, 68-1247-061<br />
for 500D, or 68-1247-104 for 1000D). Installation and operating<br />
instructions for this system are located in Section 8.<br />
In this mode the softkeys toggle between the options described in<br />
