Setting the run parameters
64
Position
This setpoint indicates which tower is on which inlet (front or back). Typically, 
the location of the injector cable in the controller box, front or back, is the 
position associated with that injector.
With an INET integrator and dual injectors, this setpoint specifies which 
injector, front or back, is associated with the INET data channel and which is 
associated with the auxiliary data channel. This parameter determines where 
the sample vial numbers are printed when more than one injector is installed.
On the 6890 Series GC, the position of the injector cables are not significant 
because you can set the injector position from the keypad. With only one 
injector, you no longer have to move the cables when you move the tower, 
merely reconfigure the tower position.
Caution Always turn off the power to the controller before you remove and reconnect 
the injector cables.
