-- EC300A/EC400 Inputs Screen #3 --
The third input screen displays the current status of each limit switch as well as the status of the
safety sweeps and the two stop loops. Limit switches can be: 1.) Compressed – aisle completely
closed. 2.) Acel/Decel – near limit open far limit closed. 3.) Extended – both limit switches
open. 4.) Panto. Open – far limit open but the near limit closed, usually seen with pantograph
limit switches. Pressing the "ESCAPE" key returns to the Diagnostic Selection screen.
Pressing the DOWN key displays the last of the input screens, shown below.

-- EC300A/EC400 Inputs Screen #4 --
The fourth input screen displays the status of the security lock input, the status of all the inputs of
the system face panel control, and the status of the four option inputs. For an EC300A system,
when the associated key on the Program Key (also known as the ON/OFF/STAT/MOVE key) is
pressed the display will show a 1. In this example, the OFF key is read as being pressed. If the
safety override key is used the fifth digit would be a 1. An EC400 system utilizes infrared keys
for the same functions and the FIXED key alternates between making the carriage a stationary or
a moveable. If any of the option inputs (on the controller board) reads "Closed,” a special system
feature has been activated. These options will be discussed in more detail later in this manual.
