Initialization Mode
4-33
Flywheel Timer should be set to the cycle time below which it is safe to reverse or bar the
press. This setting affects both Forward-to-Reverse and Reverse-to-Forward changes in press
motor operation.
EXAMPLE
When the press is running at 60 strokes per minute (SPM), the length of time for one revolution
is 1 second (i.e., 60/60 = 1). As the press slows down to 3 SPM, the time increases to 20
seconds per revolution (i.e., 60/3 = 20). If you set the Flywheel Timer to 20 seconds, WPC 2000
will not allow reversal of the motor or barring of the press until the flywheel has slowed down to
less than 3 SPM.
Setting the ACTS Angle (Optional)
Auto-compensated Top Stop (ACTS) is an optional WPC 2000 feature that automatically
adjusts the Top-stop “On” Angle to an earlier point in the stroke to compensate for increases
in press speed. You enable ACTS via switch 4 on the Press Control Option Switch Menu (see
page 4-37 for instructions and for additional details about the ACTS feature).
The ACTS Angle setting allows you to specify the angle at which you want the press to stop.
In most variable speed applications, the ACTS angle should be set to 0°, the default value.
However, in top knock-out applications, the angle might be set after 0°, while in some
high-speed applications, it might be set before 0°. SmartPAC 2 will only accept ACTS Angle
entries between 330° and 30°. If you have questions about where to set the ACTS Angle,
contact Wintriss Tech. Support.
Selecting Pressure Units
The Pressure Units setting allows you to select the units in which pressure is displayed on
Press Control screens in Initialization, Program, and Run modes. Three Pressure Unit options
are available: PSI (Pounds per Square Inch), Kp (Kilopascals), and BAR (Bars). To select a
Pressure Unit, do the following:
1.
With the highlight bar on the current PRESSURE UNIT setting, press ENTER until the
option you want is displayed.
Note that the units in which the MAIN AIR LIMIT and C/- settings are
displayed change to the units you selected.
