Operation

5 Switching off the Cedex HiRes Analyzer

Switching off the Cedex HiRes Analyzer should always be carried out in the following order:

Carry out an LM Shutdown.

Shut down the analysis software (optional, see note below regarding the use of the scheduler).

Shut down the operating system.

Switch off the individual devices.

■

If Prime, LM Shutdown or routine cleaning routines have been scheduled via the scheduler, the software

application must be left on and the HW must be started (see “ Scheduling Automatic Cleaning Routines”).

5.1 Carrying out an LM Shutdown and HW Shutdown

All of the capillary tubes in the Liquid Management system are cleaned and rinsed with distilled or de-ionized

water during an LM Shutdown. In addition, the Trypan Blue is withdrawn from the 8-way valve/syringe and

replaced with air. This is to prevent the capillary tubes and ﬂ ow chamber from becoming damaged. The HW

Shutdown shuts down several elements of the hardware system including the scanner, Multi Sampler and pump.

Follow the instructions below to carry out an LM Shutdown:

Click on the HWM button in the Shortcuts area of the Control Center to open the Hardware Manage-

ment window. Alternatively, the Hardware Management window can be opened by selecting Hardware

Management in the Functions menu at the top of the Control Center (see Figure 47).

Click on the LM Shutdown button in the lower right-hand corner of the window to shut down the Liquid

Management. The estimated time required for the LM Shutdown is displayed in the “Estimated Total Time”

section of the Hardware Management window.

When everything has been shut down, the Current Status ﬁ eld will have the message “HW started and LM

not primed”. If both the Liquid Management and the Hardware Management has been shut down, the the

message “HW not started and LM not primed” will appear.

Click on to close the window.
