Green special sensors
Green special sensors can be used to detect excessive slug stacking or other events,
which occur periodically, but not necessarily on every stroke. This sensor must
actuate at least once during a preset number of strokes. Instead of setting a ready
signal as with a green sensor, you set a value for the preset number of strokes. If
the sensor does not activate after that number of strokes, DiPro will automatically
send a stop command on the upstroke.
CAUTION
The green special sensor is not foolproof. It is possible that an undesirable
number of slugs could conceivably stack up in an ejection hole, while still
satisfying a green special sensor's requirements.
Yellow sensors
Yellow sensors are normally open to ground. They are used to monitor events like stock
buckling, end of stock, or die overload where DiPro sends the stop command to the press as
soon as the sensor actuates. The stop type can be set for either an emergency stop or a top
stop. Yellow sensors do not actuate every stroke like green sensors. They work
independent of the press cycle. Therefore, you do not set a ready signal for yellow sensors.
Red sensors
Red sensors are normally closed to ground. They are just the opposite from yellow
sensors. DiPro sends the stop command to the press (either top stop or emergency stop)
as soon as the sensor opens (actuates). Red sensors are used where it is more
convenient to use a normally closed sensor instead of a normally open one. Red sensors
can monitor the same types of events as yellow sensors—die overload, end of stock,
buckling, etc. No ready signal is set for red sensors.
DiPro three modes of operation
You can do various things with your screen and keyboard depending on what mode you are
in.
• Initialization Mode. Used to make settings that only need to be made once after
installation. For instance, you select names for your cam timing channels in
initialization mode. You also can lock settings and set reset mode. All settings are
made using the keyboard and display. You have to set a switch inside the DiPro box to
see the displays for Initialization mode. This mode is explained in Chapter 4.
• Programming Mode. Used to make all your sensor settings and cam timing settings
(if installed) for your tools. You also set counters. You cannot use this mode while the
press is running. You can load settings for a tool in this mode. Load means you tell
DiPro what tool you are using for the job. You switch to Program mode by turning the
Program/Run key to "Prog" when the press stopped. The displays you see in Program
mode are described in Chapter 5.
• Run Mode. You must be in Run mode to run the press. In Run mode you can adjust
timing for your sensors and cam channels while the press is running. You see actuation
angles for green sensors in Run mode. You can also load tool settings in Run mode. To
switch to Run mode, you turn the Program/Run key to RUN. The settings you can
make in Run mode are explained in Chapter 6.
