The
controller utilizes a PID algorithm to control
tension in unwind, rewind or intermediate
zones. The standard output from the Tension
Controller is 0-10V / 4-20 ma, which can
be directed to a brake or a drive. Hardy
also provides pneumatic systems to convert
the analog output to a pneumatic signal
for air- brake operation.
Because
the actual product tension is measured,
this type of precision control eliminates
common process problems found in web and
strand processes including feathering, breakage,
telescoping, wrinkling, and blocking.
The
user-friendly keypad and display provide
a short learning curve for plant operators,
and menu security levels allow better control
over process set points.
The
Tension Controller also provides Quick Calibration
capabilities, which allows the user to calibrate
the web or strand process control without
the use of test weights, thus saving on
time, effort, and cost.
The
Electronic Diagnostics within the controller
allows the user to troubleshoot issues related
to installation, sensor performance, or
system noise - all through the keypad or
a PC on the same network as the controller.
