Users Guide
Mode: Signal must be seen as follows, or function sets an output action:
static continuously
cyclic Thru a preset angular window once every cycle.
Intermittent cyclic Thru a preset angular window after a preset number of press cycles
in position thru a preset angular window (with part in place)
intermittent in position Thru a preset angular window with part in place after a preset number of press
cycles.
DEFINITION OF DIE MONITORING WINDOW
Window
Input signals for Cyclic (CYC) and In-position (POS) modes are synchronized
with the rotation of the crankshaft, and must be detected within a zone of crankshaft
rotation. We call this zone a window. For example, a part-detect signal could be expected
within a window of 80-110º to indicate that a part was inside a die before it was hit by a
stroke.
When the software detects input signals that are different from those described here, the
software generates a fault signal. We graphically define these (window) inputs as follows:
DEFINITION OF DIE MONITORING WINDOW
Cyclic (CYC) N.O.
Use this mode to verify that a pulse from the sensor (OFF-ON-OFF)
occurred within the window once each stroke. For example, use it to detect that a part
moved past a monitor.
