Sensor types for DiPro
Sensors used with die protection systems are classified as red, yellow, or green. For
DiPro, there are three types of greens—green, green quick check, and green
constant.
When you make settings for a tool, you select the sensor type for each one of
DiPro's sensor inputs. This allows you to have any combination of reds, yellows, or
greens for a tool. You will see how to select sensor type in Chapter 5 where you
learn how to make sensor settings. Here we discuss what the five types mean.
Green sensors
Any sensor set to green (either green, green quick check or green constant) must be
cyclic. In other words, it must actuate during a portion of each stroke (during the
ready signal). An actuation is a closure to ground. If the sensor does not actuate,
DiPro sends a stop signal to the press. You can select an emergency stop or top
stop.
Green sensors are used to detect events that must occur during a certain portion of
each stroke. Examples are part ejection, stock feed, and part transfer.
DiPro displays the portion of the stroke green sensors actuate when you run the
press. It displays the degrees of the stroke where the sensor turns on and where it
turns off. That makes it easy to set the ready signal for the sensor. You just make
the ready signal a little longer or shorter than the actuation time (depending on the
sensor). See the procedures in Chapter 5 and Chapter 6 for complete instructions
on making and adjusting sensor settings.
The four types of green sensors are described below.
Green
When you set a sensor input to "green," the sensor must turn on at least
momentarily during the ready signal. Also the sensor must be off, at least
momentarily, at any point outside of the ready signal.
