As shown in Table 7-1, each of the five steppers can be initiated with the FS3 initiation switch.
This is possible only if any of the ten possible schedules for desired stepper is dialed on the
SCHEDULE display.
Besides FS3 initiation, steppers B and C can be initiated with FS7 and FS11 initiation switches.
FS7 is dedicated to initiate only stepper B (schedule 10 to 19) regardless of what schedule is
dialed on SCHEDULE display. FS11 is dedicated to initiate only stepper C (schedule 20 to 29)
regardless of what schedule is dialed on SCHEDULE display.
