Installing and Controlling Third-Party Devices
Gilson 321 and 322 Pumps: Installation

Device Type:

Pumps

Device Driver:

Gilson: 321/322 Pump

Supported Hardware Options:

  • Stand-alone operation of the 321 or 322 pump

  • Single Piston Mode (SPM): Both pistons deliver independently of each other. It is possible to run gradients with 2 solvents with a maximum flow rate of 30 ml/min.

  • Double Piston Mode (DPM): Only one solvent is delivered. The maximum flow rate is 60 ml/min.

 

What is required?

License:

Timebase Class 3

Select About Chromeleon on the Help menu of the Chromeleon client to check whether this license class is available.

Connection:

  • 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.)

Hardware
Prerequisites:

Control Panel:

GIL321_322.pan

Hardware Installation

Device Connection:

Connect the 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.)

Device Settings:

The communication parameters are as follows: 19200 baud, 8 bit, 2 stop, even parity, no handshake. These parameters are used for gradient elution, also.

 Tip:  

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

GSIOC Addresses

Each pump must be assigned a unique GSIOC address. For the Gilson 321 pump, enter any address between 0 and 63 on the pump's control panel.

For the Gilson 322 pump, you may use any address between 0 and 9. Set the address via the switch on the pump's rear panel.

Baud Rates

The Gilson 321 and 322 pumps use a baud rate of 19200. For the Gilson 321 pump, set the baud rate on the pump's control panel. For the 322 pump, set the baud rate via the switches on the pump's rear panel.

Restrictions:

Support is not available for the following features of the Gilson 321 and 32 pumps:

  • Operation of the pumps as master/slave system

  • Control of the Gilson 30x pumps as injection units

  • UV detector control via the 321 pump

  • Use of the four input signals from the pump (START/STOP application, PAUSE/RESUME, WAIT, and EMERGENCY programs) to trigger specific actions. Trigger these actions in Chromeleon.

  • Audit Trail functionality of the pump. Use the Chromeleon Audit Trail, instead.

  • Maintenance counters: The values are only displayed. (Exception: The user can reset the counters.)

  • Internal programs of the 321 pump. Use Chromeleon program, instead.

  • Use of an external relay contact to start the internal emergency program of the 321 pump (file no. 24) via the relay input 2. Start an Emergency Program in Chromeleon, instead.

 

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 3213/322 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 (Gilson 321/322 Pumps) tab page, select the pump type and GSIOC address.

On the Head Type and Limits tab page, determine the head type and the allowed flow rate and pressure ranges for the pump.

On the Solvents tab page, determine the number and name(s) of the solvents delivered by the pump.

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 GIL321_322.pan Control Panel or any especially developed control panel in the Chromeleon client to the corresponding timebase.

Application

Before you connect the pump in Chromeleon, turn on the device by pressing both the ON button on the pump's rear panel (the Power LED starts burning) and the ON button on its front panel (the ON LED starts burning).

 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 control panel on the 321 pump 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 321 and 322 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.
