Creating and Modifying Programs
Creating a Power Failure Program

You can determine how Chromeleon continues operation after a power failure (see Power Failure Protection). After booting the server, you may run a power failure program first.

Select Error Handling… on the Batch menu to open the Batch <Timebase> dialog box. On the Error Handling tab page, click the Browse button in the Power Failure Handling section and navigate to the power failure program to be used.

If a power failure program is not yet available, create a program for the timebase on which you want to use it. Make sure that all instruments are reconnected to Chromeleon first. Very often self-tests have to be performed during which the devices are not ready for access. Therefore, issue the Connect commands 1-2 minutes before the first Control Commands are sent to the instruments.

Example:

Use the following program example, for example, for a Timebase that contains an ASI-100 Autosampler, a UVD 340U Photodiode Array Detector, and a P580 pump:

-2.000 UV.Connect

 Sampler.Connect

 Pump.Connect

-1.500 Lamp = On

; After the UVD 340U has been turned on, the detector needs some time
; for spectra; calibration. That is why you have to issue this
; command, too, some minutes before data acquisition is started.

0.000  Flow = 0.300 

1.000  Flow = 1.000 

 End
