====== Changing which lines the Trolley car feeds to/from ======

{{ :trolley_car.jpg?400 |}}

On the trolley car HMI (touchscreen):

  * The first column is for the Post (line 11)
  * The second column is for the J&L (line 12)
  * The third column is for line 13
  * The fourth column is for line 14
  * The bottom row of buttons enables/disables the line for the corresponding column
 
Line 14 is the conveyor line immediately to the right of the HMI.  The conveyor beyond that is line 13.

== Example: ==

In order to get the trolley car to feed the J&L from line 13, the button on the top row of the line 13 column must be pressed, and the resulting popup number pad must have //12// input and entered. The button on the top row of the J&L column must have //13// entered.  The enable/disable buttons for both columns must be highlighted in order to be enabled.  The physical trolley must also be in automatic.
