Guidelines for setting sensors
It is important that you understand the general procedure for making sensor settings. That
is because DiPro displays the actuation times for green sensors. That makes it simple to
set ready signals. (See "Sensor terminology" if you do not understand these terms).
The guidelines below are not step-by-step instructions. They are in Chapter 5. These
guidelines give you the general method you should follow. Do not worry if you do not
understand all of it now. You can learn what you do not know in Chapter 5. The
important thing is to understand how you can use DiPro 1500 to easily set ready signals
for your green sensors. Here is what you do:
•
After your die is in place, all sensors are installed and connected, and you are
ready to make parts, you make settings for all your sensors. For your green
sensors, you should set the ready signal large enough so that you are sure each
sensor will actuate within the setting you make. This is so you can run the press
briefly later without the sensor signalling a malfunction. If you are not sure what
to make the ready signal, estimate it.
•
You load the settings for the tool (tell DiPro the tool number to use) and run the
press for one or more strokes so all green sensors actuate.
•
After running the press, you will be able to see the actuation angle for each green
sensor when you call it up on the display.
•
You then adjust the ready signal based on the sensor's actuation angle. For
instance, if you see that a green sensor came on at 190° and went off at 270°, you
might make the ready signal 180° on–280° off. That gives you a tight ready signal
for the sensor based on its actuation angle. There is no trial and error.
•
You then set the ready signal for all your other green sensors in the same way,
taking note of whether the sensor is of type green, green quick check, or green
constant. (The ready signal for a green constant sensor has to be a little shorter
than the actuation angle.)
•
When all adjustments are made, you are ready to make parts.
Considerations for setting sensor stop type
You can set the way DiPro stops the press for each sensor. Here are a few general guide-
lines for how to set stop type. Use Emergency Stop (E Stop) when you want to stop the
press before the next hit. For instance, when monitoring part ejection on the upstroke,
you can use the E stop setting so DiPro will send a stop signal to the press immediately if
a malfunction occurs. This ensures that the press will stop in time before the next hit.
However, if you are monitoring a feed that takes place well into the downstroke (like a
roll feed) you would probably want to set the feed sensor for a top stop. An E stop setting
here may cause the press to stick on bottom. That is because the stop signal would be sent
just as the ram is about to contact the material.
The general rule is to use E stop when you want to make sure that the press will stop
before the next hit. Use top stop when (1) an E stop setting might cause the press to stick
on bottom and (2) when one hit after a malfunction will not damage the die or press.
