not the source is ground-referenced. Table 2 lists the
recommendations for enabling vs. disabling the SCC: 3.2.3 Shunt Mapping
Shunts CH1 through CH7, located on the circuit board as
shown in Figure 2, control the enabling of the channel
SCCs. Each channel is affiliated with one shunt. To
enable a channel’s SCC, you must install the affiliated
shunt. Similarly, to disable the SCC, you must remove
the shunt.
Table 3 shows the mapping between channels and
affiliated shunts for SCC enables.
For example, install shunt CH2 to enable the SCC for
sensor channel 2.
