3.7 SYS MODE SETUP AND OPERATION
Sys mode uses external current sources, such as 12 V
DC
, to exercise and demonstrate
the features of the PAC1710 and PAC1720.
3.7.1 Jumper Positions
To use Sys mode, adjust jumpers J3, J4, J8 and J9 (see Table 3-2 ) to disconnect the
on-board demonstration current sources.
3.7.2 Load Connection
A 3 m

(1% tolerance) sense resistor is provided on-board the PAC17X0 High-Side
Current Sensors Evaluation Board to measure system current. For V
SOURCE
1, this
sense resistor is connected between J17 and J18 if using these power jacks, or between
J1 and J2 if using wire terminals. For V
SOURCE
2, this sense resistor is connected between
J19 and J20 if using these power jacks, or between J6 and J7 if using wire terminals.
When using wire terminals, connections to the system can be established as shown in
Figure 3-3 .
