Description
An output (contact closure) to indicate that an injection began.
Connect a wire pair to the two Inject start terminals.
An input that enables other LC components to stop the solvent flow from
the separations module. You specify the signal conditions that stop the
flow using the Events In screen key in the Configuration screen.
Connect the positive input wire to the "Stop Flow +" terminal and the
negative input wire to the "Stop Flow -" terminal.
Inputs that enable other LC components to delay the injection (for
example, an external autosampler used in the Operate Gradient by Event
In mode or a fraction collector). You can specify the signal conditions
(using the Events In screen key in the Configuration screen) that prevent
the separations module from making an injection.
Connect the positive input wire to the appropriate "Hold Inject +" terminal
and the negative input wire to the appropriate "Hold Inject -" terminal.
