West Controls N6600 and N8600 Single Loop Controllers for Plastics Applications

West N6600 and N8600 single loop controllers are designed specifically to provide quality process control for the plastics extrusion market. Special heater break alarms give early warning of equipment failure, protecting both the equipment and your end product.

Quick Transfer is a one shot operation that automatically sets the heater break alarm condition based on the nominal current value. An Auto/Manual key can be configured for fast access to display amps or process temperature. The 6600 controller includes West's advanced tuning algorithms, with selectable pre-tune and self-tuning. Pre-tune, a one-step tuning algorithm, is used on startup to get you to setpoint fast. Self-tuning, a continuous adaptive tuning algorithm, is enabled near setpoint and normal operating conditions to control overshoot.

Key Specifications

  • Four outputs, one sensor input, one current transformer input, plus RS-485 communications option
  • Heater break alarms reduce scrap and improve quality by detecting heater loss prior to production problems
  • Two standard tuning algorithms: Pre-tune for fast startup and Self-tune adaptive tuning
  • Quick transfer automatically sets heater break alarm conditions based on the nominal current value
  • Soft Start prevents premature heater failure due to high levels of moisture in heaters at start-up
