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.

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. 

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.  

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). 

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.
