When HO, OF (SCHEDULE "N") and SQ (SCHEDULE "N+1") are all programmed to 00
cycles, the sequence will jump directly from the end of WELD Time (SCHEDULE "N") to
the beginning of WELD Time (SCHEDULE "N+1"), without any interval between the two
WELD Times (continuous weld current).
The SCHEDULE number displayed after the end of a CHAINED SEQUENCE depends on
the EXTENDED FUNCTION [SS] INTERNAL/EXTERNAL. If it was programmed in the
EXTERNAL mode, the SCHEDULE number displayed will be controlled by the
combination of SS1, SS2 (See Section 2.1 CONTROL FUNCTIONS/SCHEDULE
NUMBER SELECTION). If it was programmed to the INTERNAL mode, the SCHEDULE
number will be the last number entered using keys (21) and (20). 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 7.3 EXTENDED FUNCTIONS and section 7.5 SCHEDULE SELECT.

SUCCESSIVE MODE is similar to the NON REPEAT and CHAINED MODES of
operation. 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 SELECT 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 SCHEDUAL 03 will be completed and the SCHEDULE Display will again show
SCHEDULE 01.
When the EXTENDED FUNCTION [SS] SCHEDULE SELECT INTERNAL/EXTERNAL
MODE is programmed to the EXTERNAL [0E] Mode, the SUCCESSIVE series will start
with the externally selected SCHEDULE and will automatically return to that SCHEDULE
once the series is completed. See section 7.3 EXTENDED FUNCTIONS.
The BACK-STEP FUNCTION can be used to return to SCHEDULE "N-1" or even "N"
without continuing through the rest of the SUCCESSIVE SCHEDULES. A momentary
closure of the BACK-STEP (TLS1/AUX1) switch will cause the control to return the
previous SCHEDULE. This can be repeated until the first SCHEDULE of a series is
reached. A maintained closure (approximately 1.5 seconds) will cause the control to return
the first SCHEDULE in the series. If the BACK-STEP switch is maintained after the control
reaches the first SCHEDULE, an ERROR CODE 06 will flash in the DATA DISPLAY (4).
