Setting The Ready Signal For A Green Sensor - Honeywell SmartPAC 2 User Manual

SmartPAC 2 with WPC Integration
To set stop type for red, yellow, green, green quick check, and green constant, select the
setting you want for the sensor—emergency stop, top stop, or Smart Stop.
After you make the stop type settings for red and yellow sensors, you are done. Green
sensors, however, need additional settings to be made. SmartPAC 2 brings you back to the
display listing the remaining sensors. You can set another sensor. Go to the section, "Setting
the other sensors for the tool."
When you highlight "Smart Stop" and press ENTER, a display immediately appears which
asks you to set "critical angle." Critical angle is the last angle position in the crankshaft
rotation to signal an emergency stop so that the ram can be stopped before the punches make
contact with the material. The critical angle affects all the sensors that are set for Smart Stop,
and only needs to be set once for the tool.
If you need to modify the critical angle at a later time, you can access the "Set the critical
Angle" display by pressing F5 from the "Setting stop type" display (Figure 5-16).

Use cursor keys to change the angle value. Then press ENTER when done (see Chapter 3 for
help in using cursor keys). You will be able to continue setting up the sensor.
Next we explain how to set the ready signal for green, green quick check, and green constant
sensors and the counter for green special sensors.

Setting the Ready Signal for a Green Sensor

After selecting stop type for a green sensor, you will see the display in which you set the
ready signal the "ready on" angle and "ready off" angle (the "ready signal"). The ready signal
is the timing window during which the sensor must actuate or SmartPAC 2 sends the stop
signal to the press.
You .set the ready signal; so that it is a little longer than the sensor's actuation time for green
and green quick check sensors. For green constant sensors, you set it so that it is a little
shorter than the sensor's actuation time. See Chapter 1 for an explanation of the different
types of green sensors.
