monitoring is described in the “Track PLS and Track PLS Invert” topic of Section 3. When an input
is defined as a Track type input, the Channel Information Area will display the PLS channel to be
tracked (labeled Track PLS Ch #). The operator must specify which PLS output channel is to be
tracked for proper operation. The system is capable of tracking PLS outputs 1 through 8.
To change the PLS channel to be tracked, gain access to the Channel Information Area (see Section
2.10.1), use the arrow keys to move the current Track PLS #, then press the CHANGE NUMBER
softkey. The operator must then enter number 1 through 8 for the PLS channel to be tracked and
press the ENT key on the keyboard.
Section 2.10.7 Programming Track Time
As detailed in the “Track PLS and Track PLS Invert” topic of Section 3, Track PLS type inputs must
follow the switching action of a System 5000 PLS output. There are, however, electrical and
mechanical delays involved from the time that the PLS output activates until the tracking sensor
which is wired to the die protection input is activated. To allow for these delays, the operator must
program a Tracking Time for any input set up as Track PLS. The Tracking Time is the time allowed
after the PLS output switches before the die protection input set up as Track PLS must also switch.
It is displayed in the Channel Information Area for any input programmed as Track. This time can
be from 4 milliseconds to 999 milliseconds in 1 millisecond increments.
To change the tracking time, gain access to the Channel Information Area (see Section 2.10.1), use
the arrow keys to move the cursor to the current Track Time, then press the CHANGE NUMBER
softkey. The operator must then enter a value for the time (4 to 999 ms) and press the ENT key on
the keyboard. .
Section 2.11 Input Capture Capability
There may be instances where it is desirable to find the exact crankshaft angle where a die protection
input changes (i.e., where the sensor wired to the input changes). This is especially true with a fast
changing input where the operator may not be able to see the change on the "State" display of the
Die Protection Menu. For example, if a part detector is being used it would be very desirable to see
exactly where the part passes the detector. This information would be helpful in setting up the
timing window for that input. By using the Capture Input feature for any input, the operator can
view the crankshaft angle at which that particular input changes.
In the Die Protection screen for any input, there will be a softkey which is labeled CAPTURE
INPUT (see Figure 2.1). The block displayed above the CAPTURE INPUT softkey displays the
pertinent information. The "Capture Status" line informs the operator of whether or not the capture
feature is active, while the "Closed at" line will display the crankshaft angles when the input
changes. To arm the capture for this input, the operator must press the CAPTURE INPUT softkey.
Once the capture is armed the module will begin to look for the crankshaft to pass through the 170
degree point (just prior to bottom dead center). Monitoring is done for one stroke beginning near
