update the sensor information, press the appropriate function key. (Function keys are
discussed in Chapter 3.)
Sensor ON-OFF Marker
Notice the "sensor on-off" box at the right of the screen and the green sensor on-off marker
inside the ready signal arc. The numbers in the box show the degrees the sensor actuated
when you ran the press. You can press the F5 function key to refresh the screen (refer to the
section on "Function keys" in Chapter 3 if help is needed). The marker outside the arc
graphically shows the sensor's actuation time — the earliest "on" angle and latest "off" angle.
It is easy to adjust the ready signal so it is just a little shorter than the sensor's actuation angle
(for green constant sensors) or just a little longer (for green and green quick check sensors).
Any time you run the press and display the ready signal for a green sensor, you will also see
the sensor's actuation angle. Notice the sensor actuation arc on the ready signal circle
diagram. The circle diagram dynamically illustrates the on and off angle settings that you
programmed for a sensor and/or cam channel, as well as the sensor actuation arc..
How SmartPAC 2 Displays Sensor Actuation Times
SmartPAC 2 does not show every stroke-to-stroke change when displaying sensor actuation
time. For sensors set to green and green quick check, it shows the earliest on angle for the
sensor and the latest off angle (that is, shows an increase in the actuation angle). For sensors
set to green constant, it shows the latest on angle and earliest off angle (shows a decrease in
the actuation angle).
For instance, if a green quick check sensor's on angle fluctuates between 190° and 195° from
stroke to stroke, SmartPAC 2 would show 190°. However, if the on angle changed to 189° or
lower, SmartPAC 2 would immediately display the earlier on angle.
A green quick check sensor's off angle is recorded the same way. Only with the off angle,
SmartPAC 2 displays the latest off angle.
For green constant sensors, SmartPAC 2 would only show a change when the actuation angle
decreased, not increased. That is, it shows the latest on and earliest off. SmartPAC 2 displays
actuation angles this way so that you can set the ready signal using the worst case actuation
angles for the sensor. Another reason is because if SmartPAC 2 showed every change on the
display, it might change so rapidly that you could not read it from stroke to stroke.
Updating the ON and OFF Angles for a Sensor
(RUN – DIE PROTECTION – SELECT SENSOR – F5 -UPDATE THE SENSOR ARC)
Press the F5-"Update the Sensor Arc." This clears the actuation angles displayed for any
sensor. Zeros will be displayed. SmartPAC 2 will display the actuation angles for the very
next stroke. You can press the key F5 key while the press is running or stopped.
If a sensor is "on" through the top of the stroke, you may notice that the actuation angles
shown in the Sensor on/off box may appear to be inaccurate. The angles shown are the
earliest and latest actuations of the sensor in reference to 0° (top of stroke). If a sensor turns
"on" before 0° (say, at 350°), SmartPAC 2 will not recognize 350° as the earliest actuation
because the number "350" is higher in value than the number "0." If the information in the
