5.5 VIEWING FUNCTION VALUES
NOTE
Insure that section 5.2 ( use of Next/Prev keys) has been reviewed before
proceeding.
1. Pressing the NEXT SCREEN key after the weld schedule has been selected
from the library will result in the following screen:
# OD WALL MAT HEAD PASS READY
001 1.500 .065 SS 95 01 TO TEST
*LVL-TIME PRI--AMP--BCK PRI-PULSE-BCK*
01 000 000 000 0.00 0.00*
The above shows amperes, pulse times and level time (duration) for level 1 of
the schedule.
2. After reviewing this information the operator can do one of the following:
1. Make changes to these level 1 functions (see 5.6)
2. Press the NEXT LEVEL or NEXT SCREEN key to review the entire weld
schedule as depicted in figure 7 and make changes if desired.
3. Press the SEQ START key to run this weld sequence
5.6 OVERRIDING FUNCTION VALUES
Each weld schedule in the M-227 library can be programmed to allow unlimited,
limited or NO changes to be made to the function values of the weld schedule. If the
weld schedule allows changes to be made use the following procedure.
1. Use the NEXT SCREEN and/or NEXT LEVEL keys until the function value
to be changed appears on the screen.
2. Directly above and below each function value is an F key. When either one is
pressed the first time, the function to be changed will start to blink.
3. The value can be changed two ways. A small INCREASE in the value can be
made by pressing the UPPER F key. A DECREASE in the value can be made
by pressing the LOWER F key. Each time the F key is pressed the value will
change by the smallest programmable increment. Large changes should be
done by using the numeric keys. With the function blinking (step 2) enter the
new value using the numeric key pad. Verify that the new value appears on the
display. If you make a mistake press the CE key and try again.
