2. Consignes de sécurité
AVERTISSEMENT : Risque de choc électrique. Coupez l’alimentation avant toute installation ou intervention.
- Veillez à ce que tous les travaux de câblage soient effectués par du personnel qualifié et soient conformes aux normes électriques locales.
- Vérifiez le volume de l'alimentationtage matches the controller's specifications (100 to 240 Vac).
- Do not operate the controller in environments exceeding its specified temperature and humidity ratings.
- Avoid exposing the device to corrosive gases, liquids, or excessive vibration.
- Always use appropriate personal protective equipment (PPE) when working with electrical equipment.
3. Installation
3.1. Montage
The PXU10020 is a 1/16 DIN panel mount controller. Cut a panel opening of 45 mm x 45 mm (1.77 in x 1.77 in). Insert the controller into the opening and secure it using the provided mounting brackets. Ensure a snug fit to prevent dust and moisture ingress.
3.2. Câblage
Connect the power supply, universal input sensor, and relay output according to the wiring diagram provided with the product. The universal input supports various sensor types (thermocouple, RTD, voltage, current). The relay output provides switching capabilities for control elements. Ensure all connections are secure and correctly polarized.

3.3. Mise sous tension initiale
After all wiring is complete and verified, apply power to the controller. The display will illuminate, and the controller will perform a self-test. Refer to the display for any initial error messages.
4. Fonctionnement
4.1. Basic Control Modes
The PXU10020 supports various control modes, including PID (Proportional-Integral-Derivative) and On/Off control. The appropriate mode should be selected based on the application requirements for stability and precision.
4.2. Réglage des paramètres
Use the front panel buttons to navigate through the menu structure and set parameters such as the desired setpoint, alarm limits, and PID tuning constants (P, I, D values). Consult the detailed programming guide for specific menu navigation and parameter definitions.
4.3. Interprétation de l'affichage
The controller's display typically shows the current process value (PV) and the setpoint (SP). Status indicators may include output status, alarm status, and auto/manual mode. Refer to the controller's display legend for detailed icon meanings.
5. Entretien
5.1. Nettoyage
Nettoyez périodiquement le panneau avant avec un chiffon doux et sec.amp cloth. Do not use abrasive cleaners or solvents, as these can damage the display and housing. Ensure no liquid enters the controller.
5.2. Étalonnage
For critical applications, periodic calibration of the input sensor and controller may be required. Refer to the manufacturer's recommendations or consult a qualified service technician for calibration procedures.
6. Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| La manette ne s'allume pas. | No power supply; incorrect wiring; blown fuse | Check power connections; verify wiring; replace fuse if necessary (by qualified personnel) |
| Lecture de température incorrecte | Sensor fault; incorrect input type setting; wiring error | Check sensor and wiring; verify input type configuration in settings |
| Sortie non commutée | Output wiring error; control mode issue; relay failure | Verify output wiring; check control mode and setpoint; test relay (by qualified personnel) |
| Unstable control | Incorrect PID tuning parameters; sensor noise | Retune PID parameters; check sensor for noise or interference |
