3.2.6.2 DIP Switch Functions
DIP Switches are described in this section. The functions of the DIP switches are shown in the table below.
Table 3-6: DIP Switches
3.2.6.3 Sinking/Sourcing Mode for Safe Disable Inputs
Use jumper S3 on the Interface Board to select between Sink mode, Source mode, or external power for the Safe
Disable inputs H1 and H2 (as shown in Table 3-7). Jumper S3 is also used to disable the Safe Disable inputs H1
and H2, with the jumpers in place the Safe Disable inputs are disabled. Remove H1 and H2 disable jumpers if
external Safe Disable functionality is to be used. Refer to Figure 3-12 for locating jumper S3.
