As listed in Table 4.A, backplane switch positions 2 thru 8 correspond
with configuration bits 01 thru 07. The voting processors in your
clutch/brake modules allow press operation only if the set (on) and reset
(off) states of configuration bits in your program correctly match the ON
and OFF settings of corresponding backplane switches. The voting
processors check for correct configuration when you apply power to your
clutch/brake controller or change its mode of operation using the mode
select switch.
