SmartPAC 2 with WPC Integration 1126800
Installing SmartPAC 2 and WPC Chapter 2 page 35
Wiring the WPC
WPC requires:
• motor forward auxiliary contact (24V)
• slide adjust monitor circuit (24V)
• motor stop circuit (110V) if applicable, and
• motor reverse auxiliary contact (24V) if applicable
The power to WPC should come from the step-down control transformer and should be
capable of handling 100 VA at 115 VAC ± 10%.
Most of the original controls on the press will be replaced except the disconnect, motor
starter, and control transformer. It is important that rewiring allows proper operation of the
motor starters.
Slide Adjust Considerations
If your press has a motorized slide (ram) adjustment, prevent slide adjustment while the press
is running. Connect spare contacts on the slide adjustment switches (slide-adjustment-on, or
up and down switches) to the WPC emergency stop circuit to stop the press as soon as the
ram adjust switches on. For help in determining how to connect this wiring, contact Wintriss
Tech Support.
Connecting AC Wiring to WPC
DANGER!
ELECTRIC SHOCK OR HAZARDOUS ENERGY
• Disconnect main power before installation.
• Remove all power to the press, press control, and other equipment used with the press.
• Remove all fuses and “tag out” per OSHA 1910.147 Control of Hazardous Energy (Lockout/
Tagout).
• Ensure that Installation is performed by qualified personnel.
• Complete all wiring installation procedures before connecting to the AC power source.
Failure to comply with these instructions will result in death or serious injury.
All wires can be run through a flexible liquid-tight conduit to the WPC as long as all circuits
are 115V. If your top stop circuits and emergency stop circuits are low voltage circuits (for
example, 24V), run two conduits—one for 115V wires and one for 24V wires.
Bring the wiring connections for AC power to a convenient point so that you can connect
them to the WPC power supply board (see Figure 2 - 37, page 160). No. 16 wire (No. 14, if
