THE HELM-PAK SYSTEM
Helm-Pak consists of an operator interface type enclosure containing the, run buttons,
press control processors, magnetics and Human Machine Interface (HMI). These
components are laid out for the maximum operator efficiency.
The control enclosure(s) contain Allen-Bradley SLC PLC’s, operating pushbuttons,
selector switches and the operator Interface.
The dual rack configurations provide the redundant control of the clutch and brake
system. Both controllers monitor all clutch/brake I/O and exchange information about
machine status. They are linked by hardwired I/O so if one controller detects a condition
different from that detected by the other, the control logic is designed to declare a fault
and turn off all outputs to press valves. The other controller is designed to follow suit.
Compliance:
The package uses two redundant processors with application software for self testing and
verification to meet the safety requirements of ANSI B11.1, OSHA 1910.217 and
CAN/CSA Z142-M90 press safety regulations for mechanical stamping presses.
