Connection:

USB Connection

A free USB port and the following cable is required:

• USB cable (Dionex part no. 6911.0002) to connect the device to the server PC via the USB port.

• A 6-wire cable (Dionex part no. 70-9419) is required to connect the Waste Bottle/Waste Level Detector Assembly (Dionex part no. 70-9363R) to the Corona ultra RS.

Pump Connection

If the detector is operated with an UltiMate 3000 pump, the following additional signal cables are required:

- UltiMate 3000 LPG-3400XRS pump:

• Synchronization cable (Dionex part no. 6043.0003). The cable is shipped with the detector.

  Detailed instructions for connecting the Corona detector with an LPG-3400XR pump are also provided in the Operating Instructions of the pump.

- UltiMate 3000RS/SD/BM/BX pumps:

• 6-pin Mini-DIN signal cable (Dionex part no. 6000.1004)

• Required pump firmware version: 2.20 or higher

- All other UltiMate 3000 pumps:

• Shutdown cable (Dionex part no. 6035.0004).

• Required pump firmware version: 3.05 or higher

  For details on installing the cables, refer to

   ESA Corona CAD: Interfacing the detector with an UltiMate 3000 Pump

   Dionex/ESA Interface Cable

For details on cable connections when operating the Corona detector with an UltiMate 3000 pump and an OAS-3x00TXRS autosampler, refer to:

UltiMate 3000 Series OAS-3x00TXRS Autosampler: Connecting the Autosampler.

Limitations:

If multiple Corona detectors are installed on a single PC, communication problems may occur in the following situations:

• when switching off one of the detectors,

• when connecting an additional detector with the PC.

To resolve the communication problems, you have to re-assign the USB address to the detector. To do so, on the General tab page, click Browse in order to load the correct USB address again.

Control Panel:

To control the detector, use

• panel tabsets (refer to How to:  Controlling Devices from the Panel Tabset)

  OR

• Corona CAD.pan from the
  Dionex Templates\Panels\Dionex_LC folder in the Browser

Safety Connection:

 Caution:

Dionex recommends connecting the PUMP OFF output contact of the detector to the pump, so that, if the pressure of the nebulizing gas falls below 50% of the required gas volume, the signal may be used to shut the pump off so that the detector is not flooded with mobile phase.

Device Connection:

First, install the Chromeleon software, and then connect the instrument to the USB port on the Chromeleon server PC.
