2 Working with the Control Module
Connecting External Devices
Stop
This signal asks all modules to reach the ready state as soon as possible. It
works only during the analytical run (controlled by the stoptime setting) and
causes the system to begin counting down the postrun time.
Ready
When all Agilent 1200 Series modules are ready for the next analysis, this
signal is on. Other modules or external devices now can react (e.g. by issuing a
start request).
Prepare
This causes the modules to get ready for the next analysis (e.g. the detector
will perform a balance).
Start Request
This signal causes the modules to get ready for the analysis (e.q. the
autosampler will begin the injection cycle). As soon as all conditions to start
the analysis (the injection needle is placed in the seat and the valve is in the
proper position) are fulfilled, a Start signal is generated to inform the other
modules that now the analytical run starts.
Start
In standard mode only the autosampler creates this signal. This sends an
order to start run-time controlled activities to all the modules connected to
the APG remote bus. From now on (moment of injection) the runtime counts
up.
