On the I/O board, check the supplied nominal current ratings of the current transform-
ers (5 jumpers) and the selected pickup voltages for the binary inputs BI4 through BI11
according to Table 8-4.
Figure 8-6 Jumpers on the I/O Board for the Current Transformers and the Binary Inputs
BI4 to BI11 (simplified)
The X3 and X4 jumpers for configuring the terminating resistors of a serial interface
are on a card that is located on the CPU board. The card is attached to the associated
serial port at location "B" or location "C" (designated on the rear of the 7SJ62). There
can be one or two cards. There are two variations of the card that are differentiated
only by the arrangement of the components. See Figures 8-7 and 8-8. The jumpers
are set according to Table 8-7 and 8-8. Jumpers X3 and X4 must always have the
same setting. The factory settings for the jumpers are 1-2.
