-- Power Pro Inputs Screen #3 --
The third input screen displays the current status of each limit switch as well as the status of the
photo and mechanical safety sweeps. 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. If the parameter setting selects the disable photo sweep option AND the JP4
jumper is in place then the photo sweep will be shown as disabled. Pressing the "ESCAPE" key
returns to the Diagnostic Selection screen.
Pressing the DOWN key displays the last of the input screens, shown below.

-- Power Pro Inputs Screen #4 --
The fourth input screens displays the status of the security lock input (J23 Pins 1&2), the module
off input (J23 Pins 3&4) and the photo sweep adjustment inputs. The security lock input is
active when the jumper is removed (open). The module off control is active when the jumper is
in place (closed). Both of these inputs are typically interfaced to panel mount keylock.
JP1 increases the photo sweep power by one.
JP2 increases the photo sweep power by two.
JP3 increases the photo sweep power by four.
JP1 through JP3 are additive, that is the power increases from 1 to 8 and can be selected by
varying the jumper combinations. JP4 jumper is used with the Disable Photo Sweep Parameter
screens to disable one or both photo sweep circuits. Every aisle should be protected by either a
photo sweep or mechanical sweep mounted on at least one side of the aisle.
