Automated Control System
precision, and years of productive use have made HYGE the industry
benchmark for repeatable pulse testing, and our newest
developments in touch screen operation software raise the bar
even higher. HYGE's new software reduces training time,
increases productivity, and dramatically enhances safety.
HYGE's new software, which is easily adapted to
horizontal or vertical HYGE systems of all sizes, is a well-designed
HMI controlled by a programmable logic controller (PLC) which
allows the user to control the various system components while
monitoring every pressure transducer and the state of all permissive
and control power signals. System procedure written into the
code eliminates a major source of user error; fail-safe operation
is guaranteed by ensuring that certain processes be carried
out in a particular order. In addition, all permissive signals
are required before the cylinder can be filled with high pressure
air and the ram can be fired, simulating a collision.
The control system features an intuitive user
interface that provides controls for every automatic function
of the system, from the automatic filling of the system pressure
to the storing of successful test parameters data. The potential
for user error is further reduced by incorporating proper procedures
into the code and providing a live system schematic on screen.
The initial screen is dedicated to data entry
of test parameters and displaying the output of sensors which,
along with several pressure transducers, provide signals to
the computer via communication with PLC input modules. These
signals are calibrated as determined by tag scaling settings,
which can be edited by users who have appropriate security privilege.
Other screens feature controls and indicators
that run the pressure systems and record feedback. Pressure
system preparation is accomplished on the screen, which displays
all the complex system controls and indicators without crowding.
Automation features include filling pressures
to target values, digital ten second countdown display, logging
of test parameters, and the firing process itself.
The PLC’s single-control ram-firing process
incorporates control of lights, film and video cameras.
