Tenter Frame Control

PRODUCT OVERVIEW: Tenter frame control provides control signals for speed, steam, etc. and temperature set points or signals for gas controllers. This provides easy setup by a single code number and convent data gathering.

Fully integrated  supervision insures the best control of system variables and alarming for out of tolerance conditions for enhanced quality and efficiency. Lot and style information can be entered with keypad and down time causes can be recorded. Reporting can be tailored to your needs including uploading to other computers.

SETUP PROCEDURE: Each setup code number contains all the necessary information to operate the range properly for a particular finishing application. Speed, temperatures for predryer and all heating zones are stored along with other parameters for your particular frame. This data is typically entered by a supervisor and can be password protected. Alarm tolerances are also stored and used during operation.

CONTROL TECHNIQUES: Full, direct, digital control with PLCs allows control of temperatures, speeds, flows and many other machine parameters with the exception of gas which requires an approved safety controller. Level signals or set points can be sent directly to the gas controller. Inputs can be RTD temperature probes or voltages, currents, pressures, pulses, and from other instrumentation or controllers. Any parameter needed can be monitored or controlled and future modifications can be easily accommodated. Range speed is smoothly transferred from manual to automatic and can be adjusted easily.

Important variables are displayed on the screens out on the production floor  along with alarm conditions in graphical and text format. Alarms are also indicated by horns, lights or both as desired for maximum usefulness. Alarm and status information is also available on the associated supervisor computer.

The controller enclosure is located adjacent to the frame and contains a PLC that is networked to the supervisor computer. The supervisor computer can view the same information as any of the PLCs if needed.

DIAGNOSTICS/ALARMS: All valves and controls can be tested with the diagnostic program. This allows easy trouble shooting of mechanical components in the system for functional verification. Alarm history data assists in easy location of other possible causes of low finishing efficiency or increased seconds.

Normal conditions are indicated in green, borderline conditions in yellow and alarms in red. A quick glance at the screen is all that is needed.
