Tab Dialog Box:
Relays/Inputs/Devices/State Devices

The Relays, Inputs, Devices, and State Devices tab pages indicate the names of all available relays, remote inputs, TTL inputs and/or outputs, and remote outputs. If there are no entries in the Name column, the instrument does not have these features installed.

 

Column

Description

 

 

Name

Selecting a check box in the Name column enables Chromeleon control of the corresponding relay, remote input, TTL input or output, or remote output. Clearing a check box disables control of the device.

To change the name, press the F2 key and enter a new name.

 

 

Function

Indicates the preset functionality of the corresponding relay, remote input, TTL input or output, or remote output.

 Tip:

You can change the relay functionality for some devices. After you have changed the functionality on the instrument, the description in this column does not necessarily correspond to the actual functionality.

 

 

Inject Valve options (for ICS-900, ICS-1000/1500/2000, and ICS-1100/1600/2100 systems)

Controlled By

Displays the device assigned to control the injection valve installed in the system. The controlling device can be either an AS autosampler or the system module. Follow these guidelines to select the controlling device:

If an AS Autosampler is configured in the timebase, select the AS as the controlling device. This lets the AS synchronize sample preparation operations and sample overlap with sample loading and injecting.

If no autosampler is configured or if an autosampler that Chromeleon does not control is configured, select the system as the controlling device.

To change the controlling device, select the valve name and press the F2 key.

 

The following outputs and devices are available for devices connected via USB or the Dionex DX-LAN.

 

Outputs/Devices

Description

 

 

Relays and TTLs

Enables and disables control of the instrument’s relays and TTL outputs.

 

 

 

 

ColumnValve

Enables and disables control of a column switching valve installed in a chromatography compartment or AS50 thermal compartment.

 

 

InjectValve

Enables and disables control of an injection valve installed in a chromatography compartment, AS autosampler, AS50 autosampler, AS50 thermal compartment, or DX-120.

InjectValve_2

Enables and disables control of a second injection valve installed in an AS or AS50 (USB) autosampler.

This option is available only when the autosampler is in the Simultaneous mode.

Diverter Valve

Enables and disables control of a diverter valve for an AS or AS50 (USB) autosampler.

This option is available only when the AS or AS50 (USB) is in the Sequential or Sequential Concentrate mode.

 

 

 

 

EluentValve

Enables and disables control of the IC20/IC25/IC25A eluent selection valve.

 

 

AnalogOut

Enables and disables control of a detector’s analog output.

 

 

Analog_Out_1
Analog_Out_2

On an ICS-3000 Detector/Chromatography (DC) or ICS-5000 Detector/Chromatography (DC) module with two detectors installed, Analog_Out_1 is assigned to the detector installed on the left side of the compartment and Analog_Out_2 is assigned to the detector on the right side.

 

Notes on ICS-1000/1500/2000 or ICS-1100/1600/2100 Configuration

For systems that include a CRD 200/300 Carbonate Removal Device and an external vacuum pump (for example, a Dionex VP Vacuum Pump):

If the vacuum pump continues to draw a vacuum when the ICS-1000/1500/2000 or ICS-1100/1600/2100 is not pumping liquid, the vacuum may damage the membrane inside the CRD. To prevent damage to the CRD, select Flow Zero as the Control Function for relay 2 of the ICS-1000/1500/2000 or ICS-1100/1600/2100. This configuration automatically turns off the vacuum pump whenever the ICS-1000/1500/2000 or ICS-1100/1600/2100 pump is turned off or the flow rate is set to zero.

To enable Flow Zero, select the Pump_ECD_Relay_2 name, press the F2 key, and select the Flow Zero check box in the Device Configuration dialog box.  For instructions on connecting the vacuum pump to relay 2 of the ICS-1000/1500/2000 or ICS-1100/1600/2100, refer to the vacuum pump manual.

Notes on ICS-900 Configuration

Relays 1 and  2 of the ICS-900 can be configured to open and close with the pump flow. This allows a connected accessory device to be turned on when the pump flow starts and off when the flow stops. To enable this feature, select the Pump_ECD_Relay_1 or Pump_ECD_Relay_2 name, press the F2 key, and select the Flow Zero check box in the Device Configuration dialog box. If you are using an AS40 autosampler, do not select Relay 1 for Flow Zero operation, because it is already dedicated to controlling the autosampler.

 Note:

The Flow Zero function is not available unless the version of ICS-900 or ICS-1000/1500/2000 or ICS-1100/1600/2100 Moduleware installed supports this function.

Notes on Switchos Configuration

On the Relays tab page, you can enable/disable and name the eight loading pump relays of the Switchos device. If possible, control the Switchos Switching Device directly from the PC. In this case, do not enable the SSV (solvent selection valve), Valve_A, and Valve_B relays. On the Inputs tab page, the two Switchos inputs can be enabled/disabled.
