  For details on installing the cables, refer to

  ESA Coulochem III Electrochemical Detector: Interfacing the detector with an UltiMate 3000 Pump

  Dionex/ESA Interface Cable

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

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

Control Panel:

To control the instrument, use

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

  OR

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

Safety Connection:

 Caution:

Dionex recommends connecting the detector to the ESA Model 582/584 HPLC pump via an event cable, so that if an error is registered in the pump, the cells will be turned off to avoid damage.

• Insert the event cable plug into the pump EXT.CONTROL connector (upper left-hand side on the back panel).

• Connect the orange and yellow wires to the + and - terminals on the CELL OFF I/O Connections on the Coulochem III.

• Connect the black wire (common) to the GND terminal on the I/O Connections on the Coulochem III.

To set external events on the Model 582 HPLC pump:

• While the pump is powered on, press the CE key to return to the initial screen.

• Press FUNC key repeatedly until you come to the following screen:

  0.0        EXT-S
  Input     0  -  3

• Input "2" and then press ENTER.

• Press CE to return to the initial screen.

This operation sets the Event 2 of the pump's Relay 2 (the orange and yellow wires) to present a contact closure in the event of a pump error. Now when a pump error occurs, the Coulochem III will turn the cells off. After the pump has been fixed, the cells can be turned back on.
