Section II: Schedule Screen
The
SCHEDULE
screen consists of the following
settings shown on the right.

SCHEDULE #
- The schedule number is programmable from
00
to
63
; the default is
00
on initial
operation. Changing the schedule number will automatically display that schedule on the screen.
Pressing the
PROGRAM/SAVE
pushbutton toggles between the
Program
and
Run
Modes. Placing the
system in the
Run Mode
automatically saves the currently displayed values for the schedule.
If any changes have been made in any data field,
the system will prevent the operator from
changing to a different schedule until the
changes have been accepted or rejected. The
operator will get the following message:
MODIFIED SCHEDULE NOT SAVED.
PRESSING THE PROGRAM/SAVE KEY SAVES
MODIFICATIONS, THEN PRESS DESIRED
SCREEN BUTTON AFTER SAVING.
OR PRESS PLUS OR MINUS KEY TO LOSE
MODIFICATIONS
Links
– If the schedule is part of a linked
sequence, the upper-right corner of the screen
will show the links as a set of three 2-digit
numbers.
1) First number: Previous schedule
2) Second number: Current schedule
being used (shown in brackets < > ).
SCHEDULE # 01 07<03>05

3) Third number: Subsequent schedules in the link.
In the example shown above (
07<03>05 )
, 07 is the previous schedule used, 03 is the current schedule
being used, and 05 will be the next schedule used. If the current schedule is the first of the link, the first
2-digits will be “ – – “. Similarly, if it is the last of the link, the last 2-digits will be “ – – “.
NOTE: Each of the following weld sequence settings are programmable from
00
to
99
cycles. The
default is
00
for all values except
W1
and
W2
, whose defaults are
01
.
SQD
– Squeeze delay is that period between receipt of the start signal (FS1 or FS1/FS2) and the start of
the SQZ (squeeze) time. It allows the electrodes to move to the parts and build up force.
SQZ
– The squeeze time is the delay from the receipt of the start signal (or the end of SQD) until UP
times begin (weld power is not necessarily applied). It allows the system to settle and any mechanical
motion or ringing to stop before welding begins.
UP1
– This is the upslope time for weld 1 of the sequence.
W1
– This is the weld 1 time of the sequence.
