Table A–1: Binary solvent manager analog-out/event-in connections (continued)
Signal connection Description
Run Stopped Out
Indicates (with a contact closure) the binary solvent manager has ceased
operation because of an error condition or operator request.
Switch 1 Out
Used to send time-based contact closure signals to external devices.
0−2V Analog 1 Out Outputs the analog signal to a device such as an integrator or strip-chart
recorder. Via the MassLynx software, you can select one of the following
signals as the chart out signal:
• Flow rate
• System pressure
• Composition (%A, %B)
Gradient In
Initiates the pumps to begin gradient operation by contact closure input or
0-volt input.
Stop Flow In
Allows you to stop the flow from the binary solvent manager when an error
condition or hardware failure occurs on another system module.
Switch 2 Out
Used to send time-based contact closure signals to external devices.
Switch 3 Out
Used to send time-based contact closure signals to external devices.
0−2V Analog 2 Out Outputs the analog signal to a device such as an integrator or strip-chart
recorder. Via the MassLynx software, you can select one of the following
signals as the chart out signal:
• Flow rate
• System pressure
• Composition (%A, %B)

A.7.2 Sample manager I/O signal connectors
The rear panel of the sample manager includes a removable connector that holds the screw
terminals for I/O signal cables. This connector is keyed so that it can receive a signal cable
inserted only one way.
