Hardware
Prerequisites:

  • A multi-serial, 8-fold PCI interface card (8-RS-232 Multi-Com card, Thermo Scientific part no. 5906.2095)

  • A free RS-232 port

Connection:

Required component for the Gilson 331 pump:

  • Gilson 605 GSIOC RS-232 adapter cable (For more information, refer to  Gilson 605 GSIOC RS-232 Adapter Cable in the Appendix of the Hardware Installation section. The Gilson part number for the adapter cable is 360784192. The cable is not available from Thermo Fisher Scientific.)

Required component for the Gilson 332 pump:

  • Pure GSIOC cable (Gilson part number 500933. The cable is not available from Thermo Fisher Scientific.)

 

Control Panel:

GIL333_334.pan

 

Hardware Installation

Device Connection:

The device driver supports the preparative Gilson 331 pump as a master pump and up to two Gilson 332 pumps as dependent pumps (slaves) for the delivery of other solvents.

First, connect the Gilson 331 pump to the PC:  
Connect the GSIOC from Controller port on the pump to a serial interface port on the PC, using the Gilson 605 GSIOC RS-232 adapter cable. (For cable details, refer to  Gilson 605 GSIOC RS-232 Adapter Cable in the Appendix of the Hardware Installation section. The Gilson part number for the adapter cable is 360784192. The cable is not available from Thermo Fisher Scientific.)

Next, connect the Gilson 332 pump to the 331 pump:  
Use the Gilson GSIOC cable to connect the GSIOC from Controller port on the 332 pump to the GSIOC to Slave port on the Gilson 331 pump. (The GSIOC cable is shipped with the Gilson 332 pump; the cable is not available from Thermo Fisher Scientific.)

Device Settings:

 Tip:  

For more information about the settings described below, refer to the user's guide for the instrument.

Number of Pumps

Enter the number of Gilson 332 slave pumps on the pump's control panel. On the Edit menu, select Config and then select Hard.

GSIOC Addresses

Each pump must be assigned a unique GSIOC address. For the Gilson 331 pump, enter the GSIOC address on the pump's control panel.

For stand-alone operation of the Gilson 331 pump, enter any address between 0 and 63. To operate the pump as the master pump, the address must be 1.

For the Gilson 332 slave pump(s), the address(es) must be 2 for solvent B (and 3 for solvent C). Set the address via the switch on the pump's rear panel.

Baud Rates

The Gilson 331 pump uses a baud rate of 19200. Set the baud rate on the pump's control panel. The baud rate for the Gilson 332 pump can be set to 19200 or to EXTERNAL. Set the baud rate via the switches on the pump's rear panel.

Solvent Valve Block (SVB)

When you use a Solvent Valve Block (SVB), set the SVB manually in the device configuration of the master pump. To set the SVB on the control panel of the master pump, follow the description in the pump's User's Guide. When connecting to Chromeleon, the driver checks the SVB configuration of the pumps and compares it to the settings in the Server Configuration program. If the settings do not match, an error message appears and the connect action is aborted.

Restrictions:

Support is not available for the following features of the Gilson 331 and 332 pumps:

  • Control of the Gilson 30x pumps as injection units

  • UV detector control

  • Twin pump option, i.e., doubling the flow rate by controlling two identical pump systems on the same GSIOC bus

  • Use of input signals to trigger specific actions

  • Execution of service actions (calibration, priming, leak tests, etc.) while the pump is controlled by Chromeleon. Execute these actions on the pump's control panel when the pump is not controlled by Chromeleon.

 

Software Installation

Install the Device Driver in the Chromeleon Server Configuration. (For more information about the program, refer to Software Installation and Communication  The Server Configuration Program.)

  1. Start the Chromeleon server.

  2. Start the Server Configuration program.

  3. Add the pump to the timebase. Select Add Device on the Edit or context menu, and then select Gilson from the Manufacturers list box and 331/332 Pump from the Devices list box.

  4. The following settings are required:

On the General tab page, enter a name for the pump. The default name is Pump. Select a free COM port for the GSIOC communication. In addition, verify that the Demo Mode is disabled.

On the Pump Configuration tab page, select the GSIOC addresses and the installed head types. In addition, specify whether a solvent valve block is installed.

On the Flow and press. limits tab page, determine the allowed flow and pressure range for the pump.

On the Relays tab page, select all relays that you want to control.

The Error Levels tab page classifies the severity of any errors that occur. It is generally not necessary to change the default settings.

  1. To control the installed Gilson pump, connect the GIL333_334.pan Control Panel or any especially developed control panel in the Chromeleon client to the corresponding timebase.

Application

Set the following communications parameters: 19200 Baud, 8 Bit, 2 Stop, Even Parity, and no Handshake. Use these parameters also when forming gradients or operating two or three pumps.

 Tip:  

When Chromeleon connects to the pump, the connect procedure lasts about 30 to 40 seconds. After that, Chromeleon can control the pump. This is logged in the Audit Trail.

When Chromeleon controls the pump, the pump's control panel is locked. The CM remote control message on the control panel indicates that the pump is connected to Chromeleon

Chromeleon monitors the pressure. That is why pressure limits set on the pump are ignored when Chromeleon controls the instrument. If the pressure is below the lower limit, the pump will stop after some time.

For an overview of special commands and properties for these pumps, refer to Commands and Tips for Third-Party Devices  Gilson 333 to 334 Pumps in the User Help section.

 Note:  

If you use the pumps in both local and remote operation, please note that Chromeleon overwrites the internal method files 18-20.
