5. From this screen it is possible to perform the following operations.
The application of these operations was discussed in detail earlier in
this section.
Change Tools - Alter one of the tool numbers that has already been
entered in the group. Move the cursor to the tool number to be changed
by pressing the up or down cursor keys (move the cursor full pages by
holding down the shift key while pressing a cursor key). Press the
{CHANGE TOOL} softkey. Key in the new tool number and press the
[TRANSMIT] key.
Insert Tool - Insert a new tool number for that group. Move the cursor
to the location to insert a new tool number at by pressing the up or down
cursor keys (move the cursor full pages by holding down the shift key
while pressing a cursor key). Press the {INSERT TOOL} softkey. Key
in the new tool number and press the [TRANSMIT] key. The actual
range of allowable tool numbers is 1 to 9999.
Delete Tool - Remove a tool number from that group. Move the cursor
to the tool number to be removed by pressing the up or down cursor
keys (move the cursor full pages by holding down the shift key while
pressing a cursor key). Press the {DELETE TOOL} softkey.
Change life type - Alter the method that the control uses to record and
measure tool life for that group. Press the {CHANGE TYPE} softkey.
The prompt “LIFE TYPE...” is displayed on line 2 of the CRT. Note
that the same life type is assigned to all tools in any one tool group.
Key in the number of the desired tool life measurement type for that
group and press the [TRANSMIT] key. 0 for “time”, 1 for “number of
tool uses”, and 2 for “distance”.
Important: When a change is made to the tool life type, any accumulated
life and the expected life for all of the tools is reset to zero.
Change life threshold rate - Alter the percentage of a tools expected life
that a tool will be labeled as old. This percentage applies to all tools in
the selected group. To alter the threshold percentage (the percentage of
expected tool life that has been used before a tool will be classified as
old) press the {CHANGE T RATE} softkey. Key in the percentage of
the expected life and press the [TRANSMIT] key. Tool life threshold
rate is explained earlier in this section.
All of this information may be altered for the tool groups using the
programming method discussed in section 20.5.3.
