5. Opsætning

5.1. Installation

• Panelmontering: The PXU11A20 is designed for 1/16 DIN panel mounting. Cut a panel opening of 45mm x 45mm (1.77" x 1.77").
• Sikker montering: Insert the controller into the panel opening and secure it using the provided mounting brackets. Ensure a snug fit to prevent movement.
• Klarering: Allow adequate clearance around the unit for ventilation and wiring access.

5.2. Ledninger

All wiring should be performed with power disconnected. Refer to the wiring diagram provided with your controller for specific terminal assignments. Professional installation is highly recommended.

• Strømforsyning: Connect the AC power supply to the designated terminals. Verify the voltage matcher controllerens krav.
• Universal input: Connect your process sensor (e.g., thermocouple, RTD, voltage, current) to the universal input terminals. Ensure correct polarity for DC signals.
• Relæudgange: Connect your control elements (e.g., heaters, valves, alarms) to the primary and secondary relay output terminals. Observe maximum current and voltage ratings for the relays.
• RS-485 kommunikation: Connect the RS-485 communication lines (A, B, and common/ground) to your communication network. Ensure proper termination if required.
• User Inputs: Connect external switches or signals to the two user input terminals as per your application requirements.

6. Betjening

6.1. Grundlæggende betjening

• Tænd: Once wired, apply power to the controller. The display (LCD or LED) will illuminate.
• Justering af sætpunkt: Use the front panel buttons to navigate menus and adjust the desired set point for your process.
• PID-justering: The controller utilizes PID (Proportional-Integral-Derivative) control. For optimal performance, the PID parameters may need to be tuned to your specific process. Refer to the detailed programming manual for auto-tuning or manual tuning procedures.
• Overvågning: The display will typically show the current process value and the set point.

6.2. Avancerede funktioner

• RS-485 kommunikation: The integrated RS-485 port allows the controller to communicate with a host system (e.g., PLC, HMI, SCADA) for remote monitoring, data logging, and control. Configure communication parameters (baud rate, parity, address) via the controller's menu.
• User Inputs: The two user inputs can be configured for various functions such as remote set point selection, alarm acknowledgment, or run/hold control.
• Alarmfunktioner: Configure alarm set points and hysteresis for the relay outputs to trigger external alarms or safety shutdowns.

7. Vedligeholdelse

• Rensning: Keep the controller's front panel clean using a soft, damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• Inspektion: Kontrollér regelmæssigt ledningsforbindelserne for tæthed og tegn på korrosion eller beskadigelse.
• Miljøkontrol: Ensure the operating environment remains within specified temperature and humidity ranges to prolong the life of the unit.
• Kalibrering: If process accuracy drifts, consider recalibrating the input sensor or the controller itself according to manufacturer guidelines.

8. Fejlfinding

Hvis controlleren ikke fungerer som forventet, skal duview følgende almindelige problemer:

• Ingen strøm/display:
  • Check AC power supply connections.
  • Verify external fusing.
• Incorrect Process Value Reading:
  • Ensure the universal input sensor is correctly wired and configured in the controller's settings.
  • Check for sensor damage or faulty wiring.
  • Verify sensor type selection matches the connected sensor.
• Udgang aktiveres ikke:
  • Check relay output wiring and load connections.
  • Verify set point and control parameters (e.g., PID settings, alarm limits).
  • Ensure the controller is in run mode.
• Communication Issues (RS-485):
  • Check RS-485 wiring for correct polarity and termination.
  • Verify communication parameters (baud rate, parity, address) match the host system.

For persistent issues, consult the full product manual or contact Red Lion technical support.
