Expansion Module For WPC 2000 Integrated With
SmartPAC 2.
The Option 2 Expansion Module for the WPC
2000/SmartPAC 2 provides additional press
control functions for a reasonable cost.
Features include:
20 additional user-defined inputs
4 additional pairs of user-defined
cross-checked inputs
Hydraulic overload control
Flywheel brake control
Motor current readout (if equipped with
an optional sensor)
Lube system control optional
Speed control optional
Additional User-Defined Inputs
The Option 2 Expansion Module features 20
user-configurable inputs (in addition to the 7
already present in the WPC 2000) that can be
used to monitor ancillary press functions. In
addition, the Option 2 provides 4 pairs of
cross-checked inputs (in addition to the 2
already present in the WPC 2000) for monitoring
safety applications.
Hydraulic
Overload Control
Developed for presses equipped with
an hydraulic overload system, this standard
Option 2 feature emergency-stops the press when
a hydraulic overload occurs and provides the
logic necessary to reset the system.
Flywheel
Brake Control
On presses equipped with a flywheel brake,
Option 2 can monitor a pressure or limit switch
to ensure that the flywheel brake is released or
engaged at the proper time. If the optional
Speed Control (see below) is used, the flywheel
brake can be pulsed for a specific amount of
time.
Motor
Current Readout
When wired to an optional current sensor, Option
2 provides a numeric high-and-low-value readout
for motor current (% load) during a stroke. This
information is useful for manual counterbalance
pressure adjustments.
Lube
Control
This easy-to-use, flexible option can be
programmed to monitor and control up to 3
existing lube systems, using feedback from cycle
switches, via SmartPAC 2’s Initialization
screen. If there is a lube system malfunction,
the press is top-stopped and a detailed fault
message is displayed. For one of the three
systems, pumps or shunt valves can be programmed
to turn on at certain intervals for a specific
duration and turn off after a complete lube
cycle has taken place. An initial lube cycle
can also be programmed to occur when the control
is first powered up (when controlling
counterbalance lube systems, for example).
Speed
Control
Controls the speed of variable speed presses
equipped with either eddy current or frequency
drives. Precise speeds for each mode (Inch,
Single-stroke and Continuous) are conveniently
entered and stored in the SmartPAC 2’s memory
for each tool. Press speed changes
automatically when you change the mode,
eliminating the need for speed pots and meters
on the press console.
