Recording The Pump Signals - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

5.5.6 Recording the Pump Signals

On the Signals page, the check box for the column pressure of the NC pump and the
pressure of the loading pump are selected by default when the module is installed and
configured in Chromeleon (→ page 51).
Depending on the flow meter that is installed, observe the following:
• Make sure that the corresponding signals for the flow meters (see table below) are
selected to have these signal channels available for recording the pump flow (ProFlow
flow meter only) or pump pressure (Classic flow meter only) in Chromeleon.
• If you exchanged a flow meter type (for example from Classic to ProFlow)
Make sure that the signals for the other flow meter type are deactivated (see the example
below).
When signals are selected, Chromeleon generates the appropriate channels for recording the
signals. The channels are then available in the Commands dialog box for the pump. The
channel name is generated from the entry in the Pump Device Name box on the Pumps page
(→ page 48).
If a problem occurs, the signals can provide helpful information to identify and eliminate the
source for the problem. Therefore, always record the signals of your module.
The signal ... (default name)
NC_Pump_Pressure

ProFlow flow meter only
NC_Pump_Flow_LeftBlk

Example
If a you exchange a ProFlow flow meter with a Classic flow meter, make sure that the
NC_Pump_Flow, _LeftBlk and _RightBlk signals are deactivated and the
NC_Pump_Press_LeftBlk and _RightBlk signals for the Classic flow meter are activated on
the Signals page.
Operating Instructions
Records the following signal ...
Column pressure of the NC pump.
Selected by default.
Pressure of the loading pump.
Selected by default.
If a ProFlow flow meter is installed, make sure that these signals are
activated.
Flow rate of the left flow cannel (A) of the NC pump. The flow is
measured in nL/min.
Flow rate of the right flow cannel (B) of the NC pump. The flow is
measured in nL/min.
Total flow rate from the left and right flow channel flow rates
(NC_Pump_Flow_LeftBlk and NC_Pump_Flow_RightBlk).
If a Classic flow meter is installed, make sure that these signals are
activated.
The primary pressure of the left or right pump head of the NC pump. If
the pressure is above 100 MPa, pumping stops.
