03 SUCCESSIVE: The sequence will end as if it were in NON-REPEAT mode. The
SCHEDULE display would then be incremented by one to next schedule
as in SUCCESSIVE mode but not start that sequence until the next
initiation. By using

03 at the end of CHAINED sequences, extremely
complicated sequences can be generated. The SCHEDULE display will
display the schedule number of the last schedule performed + 1.

05 WAIT-HERE: The sequence will wait for FS7 or FS11 initiation input.
When HOLD and OFF in the first schedule of a CHAINED sequence and SQUEEZE in the
second of the CHAINED sequence are all programmed to 00 cycles, the sequence will jump
directly from the end of WELD time of the first schedule to the beginning of WELD time in the
following schedule, without any interval between the two WELD times (continuous weld current).
This sequence allows two different weld currents to be introduced with one immediately
following the other.
The schedule number displayed at the end of a CHAINED sequence depends on the EXTENDED
FUNCTION SCHEDULE SELECT (
S.S.S.S.
S.S.S.S.
S.S.). If it was programmed in the EXTERNAL mode, the
schedule number displayed will be controlled by the combination of SS1 and SS2 (see Section
2.1). If it was programmed to the INTERNAL mode, the schedule number will be the last
number entered using SCHEDULE push buttons. The number displayed need not be the first
number in a sequence of CHAINED schedules. For example, if schedules 01, 02, 03 and 04 are
CHAINED together and we select schedule 02, after initiation the sequence would be as follows:
schedule 02, 03, 04 and at the completion of schedule 04, the SCHEDULE display would read
02, and not the first schedule 01. See Section 5.4 and Section 5.4.3.
6.2.4 SUCCESSIVE – CYCLE MODE=

SUCCESSIVE mode can be thought of as a CHAINED schedule being initiated one link (or
step) at a time. When the first schedule of a SUCCESSIVE series is initiated, it will sequence as
in NON-REPEAT. At the completion of the schedule, the SCHEDULE display will be
incremented by one and the control will return to the Ready state.
For example, if the control is programmed with a SUCCESSIVE series consisting of the schedules
01, 02, and 03 (01 and 02 being programmed as SUCCESSIVE schedules and 03 being
programmed as a NON-REPEAT schedule) and the SCHEDULE display is manually set to 01
and the control is initiated, the sequence of events will be as follows: the control will sequence
through schedule 01 and then increment the SCHEDULE display to 02 (flashing) and wait for
the next initiation. An initiation at this point would start schedule 02. After schedule 02 was
completed, the SCHEDULE display would then increment to schedule 03 (flashing). After the
next initiation, schedule 03 will be completed and the SCHEDULE display will again show
schedule 01.
