The local control panel is fastened to the front of the controller card.  

 

The physical panel is accessed by opening the front door of the frame.  

 

The touch screen panel is accessed through an aperture in the frame door. 

 
The panel consists of a display capable of displaying two lines of text, each 16 characters in length, and four 
pushbuttons. The functionality of the pushbuttons is as follows:
