Operation: Description:
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 tools 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. Respond yes or no and press [TRANSMIT].
Change life type Alter how the control records and measures tool life for that group. Press the {CHANGE TYPE} softkey. The prompt “LIFE
TYPE...”is displayed on line 2 of the CRT. 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.”
Change life threshold rate Alter the percentage of a tool’s expected life so that a tool is labeled as old. This percentage applies to all tools in the
selected group. To alter the threshold percentage (the percentage of total 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 total tool’s life so that the tool is
classified as old and press the [TRANSMIT] key. Tool life threshold rate is explained earlier in this section.
