procedure can be aborted at any time before the sixteenth stroke by pressing this softkey. The
previously entered limits will then remain in effect.
3.2.2.5 Turning Low Limits ON or OFF
Pressing the LOW LIMITS ON/OFF softkey will toggle all low limits (including those in all data
windows) ON or OFF. This key is only available when viewing forward tonnage (as in Figure 5 and
Figure 6). Like changing setpoints, this is a restricted operation. The operator must have access to this
operation via RUN/PROG Key or access code depending on how the system has been configured (See
section 11 on page 78 for access configuration details). When low limits are turned off, “Low Lim
OFF” will be displayed with a yellow background just below the tonnage reading on each channel.
NOTE: Individual low limits can be effectively turned OFF by setting the limit to
zero.
3.2.2.6 Turning Reverse Limits ON or OFF
Pressing the REV LIMITS ON/OFF softkey will toggle all reverse limits ON or OFF. This key is only
available when viewing reverse tonnages (as in Figure 7). Like changing setpoints, this is a restricted
operation. The operator must have access to this operation via RUN/PROG Key or access code
depending on how the system has been configured (See section 11 on page 78 for access configuration
details). When reverse limits are turned off, “Rev Lim OFF” will be displayed with a yellow
background just below the tonnage reading on each channel.
3.2.3 Setting Additional Data Window Parameters
In addition to high and low setpoints, data windows have three other parameters associated with them.
3.2.3.1 Turning Data Windows ON or OFF
Each data window can be individually turned ON or OFF. When OFF, the limits associated with the
data window are NOT enforced. To set the data window ON/OFF state, change the view to the data
window desired. The screen should look something like Figure 6. Place the data entry cursor on the
ON/OFF parameter in the View box as pointed to by “k” in Figure 6. Softkey 1 (The uppermost vertical
softkey) should read DATA WIN ON/OFF. This softkey toggles the data window setting between ON
and OFF.
3.2.3.2 Setting the Data Window “Start Angle”
The “Start Angle” for the data window is the crankshaft angle at which the setpoints associated with the
window start to be enforced. To change the start angle, change the view to the data window desired.
The screen should look something like Figure 6. Place the data entry cursor on the “Start Ang”
parameter (“l” in Figure 6). Softkey 1 (The uppermost vertical softkey) should read CHANGE START
ANGLE. Enter the new value with the numeric keypad and press the ENT key to set the angle. The
start angle MUST be less than the end angle for that data window (you may have to change the end
angle first)!
