8. (continued)
Use the numeric keys to enter the prepurge time; verify and then press the
ENTER key; then use the same method for postpurge, upslope and downslope;
then use the numeric keys again to enter the rotation; then use the F key to
select the direction of rotation ; then use the numeric keys again to enter the
rotation delay time, wire delay time, wire retract and timer mode. The same
method of instruction and entering is used for LEVEL 1 values of pulse mode,
travel mode, travel RPM, level time, amperes, wire IPM and pulse times, AVC
mode, AVC and Osc values.
NOTE
If pulse mode is set OFF the system will not ask for background functions,
backgrounds are only needed when pulsing. However, the M-227 will
automatically default a value for pulse times in case the pulse mode should be
turned ON later in a modify operation. There must be a value for Pulse Times.
9. As noted, the system follows an exact sequence through LEVEL 1. When the
last LEVEL 1 values is entered the screen will ask if you want to create
LEVEL 2; if so press the NEXT LEVEL key. If you are done , press the PRO
key and go to step 9.
If the NEXT LEVEL is used the system will copy all values of level 1 and
switch to the MODIFY mode. In the MODIFY mode you only have to make
changes to level 2 functions that are different from level 1. See section 6.2 for
MODIFY mode instructions.
10. When the PRO key has been pressed, indicating the end of level programming,
the system will display the OVERRIDE Screen.

The system automatically defaults to 100 % override. This means the operator
can make up to a 100 % change to any of these functions.
If you wish to limit the amount of changes to certain functions then use the F
key for that function and use the numeric keys to enter the desired % of change
to be allowed. When one F key is pressed, pressing another will turn the first
one off and activate the second function. When all Override % are set, press
the ENTER key.
