CHAPTER 6– CONFIGURATIONS

Internal Switch Access Control

Two DIP switches on the CPU board also provide the closure of the program mode / W&M switch
contacts. When the MultiLoad II/ RCU II does not have the external Program Mode / W&M switch
installed, it is necessary to use these DIP switches on the CPU board to enable program mode and
W&M access.
The switches are numbered 1 through 4, with 1 being closest to the front of the enclosure (top of the
picture), and 4 being towards the back of the enclosure (bottom of the picture).
When the switch is in the ON position, the switch is in the active state, allowing access. A switch is ON
when it moves right, and OFF when moved to the left.
Switch #3 is the program mode switch. Switch #4 is the W&M access switch. In the example in Figure
6.4 below, the program mode switch is currently active, while the W&M switch is not active. Figure 6.5
shows the location of the DIP switch on revision 2.x CPU boards.
A switch input is active when either the DIP switch OR the external switch is active (ON).

and W&M Access (rev 1.0)

Field Switch Access Control

The MultiLoad II also has the ability to accept field inputs for the program mode and W&M access
switches. Review the "MultiLoad II User Guide" for more information.
