Introduction to SmartPAC 2 with WPC

SmartPAC 2

SmartPAC 2 is a smart modular interface for multiple press automation functions, including
die protection and programmable cam switch. Every SmartPAC 2 includes a control-reliable,
resolver-based brake monitor, and extensive counter capabilities. SmartPAC 2 features a
large, bright color display, a numeric keypad, and other easy-to-use keys to program and run
the job. SmartPAC 2 can be connected to a computer network, which enables users to see
press parameters over the network and SmartPAC 2 to send email messages.
SmartPAC 2 can be optionally configured to include: up to sixteen-sensor die protection
system, up to sixteen-channel programmable cam switch, up to sixteen-sensor in-die
measurement system, solid-state dual microprocessor-based clutch/brake control, two or
four-input load monitoring, automated shut-height and counterbalance control, automated
press speed and lubrication control, and servo-feed interface. Each of these add-ons
optimizes SmartPAC 2 as a comprehensive press automation package. In addition,
®
SmartPAC 2 can be optionally linked to Wintriss's proprietary PACNet 3 software for data
collection, analysis and reporting.

WPC and Control Reliability

Wintriss Clutch/Brake Control (WPC) is an easy-to-use, dual micro-processor-based system
that controls part revolution mechanical power presses. With its two independent micro-
processor systems in a single modular enclosure, WPC provides dual diverse redundancy —
the latest technology in maintaining optimum clutch/brake control and operator safety. Both
of these micro-processor systems function independently of each other, have separate power
supplies, and provide separate information to the operator.
WPC meets or exceeds all ANSI B11.1-1988 and OSHA 1910.217 regulations for Control
Reliability, also referred to as "Control Component Failure." Operation of mechanical
power presses is completely governed by these two standards. Control Reliability de-
mands that a single component failure in a clutch/brake control circuit shall not prevent
the normal stopping action of the press, shall not create an unintended stroke, and shall
prevent the initiation of a successive stroke until the failure has been corrected. Proper
operation of the press consists of such considerations as: presence-sensing point of
operation devices, two hand controls, all requirements for safeguarding including safety
distance and response time, and periodic and regular inspections of power presses to
ensure safe operating conditions and adjustment. In the event that any of the conditions in
these standards are not complied with, WPC will diagnose and communicate the reason
