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) Records the following signal ...
NC_Pump_Pressure Column pressure of the NC pump.
Selected by default.
LoadingPump_Pressure Pressure of the loading pump.
Selected by default.
ProFlow flow meter only If a ProFlow flow meter is installed, make sure that these signals are
activated.
NC_Pump_Flow_LeftBlk Flow rate of the left flow cannel (A) of the NC pump. The flow is
measured in nL/min.
NC_Pump_Flow_RightBlk Flow rate of the right flow cannel (B) of the NC pump. The flow is
measured in nL/min.
NC_Pump_Flow Total flow rate from the left and right flow channel flow rates
( NC_Pump_Flow_LeftBlk and NC_Pump_Flow_RightBlk ).
Classic flow meter only If a Classic flow meter is installed, make sure that these signals are
activated.
NC_Pump_Press_LeftBlk The primary pressure of the left or right pump head of the NC pump. If
the pressure is above 100 MPa, pumping stops.
NC_Pump_Press_RightBlk
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.
