Shot counter- setting (SHOTNUM-TEST)
(vi)
Figure 2.34-16 illustrates the shot counter logic. Scheme switch [SHOTNUM-TEST] is provided
for the shot number test. For example, if two shots are required for the test, set S2 for the
[SHOTNUM-TEST]. Table 2.34-11 shows the counting up in the shot counter logic. Note that
the ARC function reaches the final trip stage if the counter is over.
