PRODUCT OVERVIEW: Package Dryer Control is a digital package dryer process control system developed to ensure consistency in drying of yarn packages. The system provides independent, single or multiple control for one to two dryers per PLC. It can be networked to other computers for data integration, coordination and lot tracking where needed.
The Package Dryer Control uses a highly reliable, PLC to control all functions needed with the most modern and complex drying hardware available today with expansion capability for tomorrow's needs. Operator friendly interfaces provide unsurpassed ease of use at an affordable price. Lot, formula, color, etc. information can be entered with the keypad and other information is collected automatically.
DRYING STEPS/CONDITIONS: Easy to enter, modify or delete procedures control:
Drying procedures are built directly on the control screens and easily assigned to the proper dryer. Operators can change set points in a procedure if necessary to handle unusual conditions.
Full digital control ensures consistent flows and reduces problems from process variations. Data gathered here can be passed to other systems or networks as needed. This will facilitate scheduling since drying is the last process associated with dyeing and dried lots are normally complete and ready to go on to the next process.
CONTROL TECHNIQUES: Full, direct, digital control allows control of motor load, pressures, times, temperatures, flows and other machine parameters. Inputs can be RTD temperature probes or voltages, currents, pressures, pulses, etc. from other instrumentation. Any parameter needed can be controlled and future modifications can be easily accommodated.
Important variables are displayed on the screens out on the production floor along with alarm conditions in graphical or text format. Alarms are also indicated by horns, lights or both as desired for maximum usefulness.
DIAGNOSTICS/ALARMS: All valves and controls can be tested with the diagnostic program. This allows easy troubleshooting of mechanical components in the system for functional verification. Alarm history data assists in easy location of other possible causes of low drying efficiency such as deteriorating components if it should ever occur.
