Gilson 202 Fraction Collector (Ext.)/204 Fraction Collector: Inputs and Outputs

Outputs (Relays for the 202 Fraction Collector (ext.) and the 204 Fraction Collector)

In the Server Configuration program, use the Relays tab page of the Gilson 202 Fraction Collector (Extended) properties to specify the outputs to be used. The seven outputs used by Gilson disabled by default. Enable the outputs that you want to use by selecting the corresponding check box, for example:

For the Gilson 204 Fraction Collector, enable the outputs in the same way:

For information about the original function of an output and the pin associated to it on the instrument's rear panel, refer to the description in the Function column. Please note that the outputs are not restricted to their original functions, but can be programmed as desired. In this case, also rename the relay in accordance with its new function to describe the intended purpose.

 Note:

Thus, the relay outputs do not necessarily reflect the internal state of the instrument.

 Tip:

If a fractionation valve is installed, the outputs can be used with restrictions only. The fraction collector switches all output channels except the Event relay to ON when the fractionation valve switches to the Drain position. This happens independently of the setting previously made by the user in Chromeleon. If the valve is switched back to the Collect position, the fraction collector adopts the settings previously made by the user.

Inputs (only 202 Fraction Collector (ext.)

In the same way, select the inputs to be used on the Inputs tab page. The eight inputs used by Gilson are displayed but disabled by default. Select the inputs that you want to use by clicking the corresponding box, for example:

You can assign different functions to the inputs in the same way as with the outputs. Therefore, the statements made above for the relays also apply to the inputs.
