3.5 Making Screw Terminal Connections with External
Devices
This section describes how to connect external devices to the screw terminals of the 600
controller. It covers:
• Screw terminal description
• Connecting a non-IEEE-488 autosampler
• Connecting a non-IEEE-488 detector
• Connecting a Waters 746 Data Module
• Connecting a chart recorder
• Connecting external devices
3.5.1 Screw Terminal Description
The screw terminals of the 600 controller enable the controller to receive signals from or
generate signals to external devices (for example, a non-IEEE-488 autosampler, a Waters
746 Data Module, or an automated switching valve).
Depending on the external devices within your particular system, use the appropriate
screw terminals listed in Table 3-1 (and the procedures in the remainder of this section) to
connect the device to the 600 controller.
STOP
Attention: To meet the regulatory requirements of immunity from external electrical
disturbances that may affect the performance of the 600 controller, do not use cables
longer than 9.8 feet (3 meters) when connecting to the screw-type barrier terminal strips.
In addition, ensure you always connect the shield of the cable to chassis ground.
