In modern industrial automation projects, the value of safety control systems is not only reflected in product performance but also in on-site installation and commissioning. As a leader in safety automation, Pilz’s safety relays and system solutions are widely used in industry, yet field projects often show “installation compliant but commissioning non-compliant.”

To help engineers avoid common issues, this article outlines the key steps from installation to commissioning of Pilz safety systems from an engineering implementation and acceptance perspective, forming a practical guide that can be directly applied.

1. Before Installation: Environmental Assessment Is the First Task

Installation is not just wiring or placing devices in a cabinet. Engineers must first evaluate whether the control cabinet environment meets product manual requirements:

• Temperature: Extreme temperatures affect relay life and reliability.

• Humidity: Moisture can cause corrosion and insulation deterioration.

• Vibration: Long-term vibration can loosen wiring or damage components.

• EMC (Electromagnetic Interference): It may cause false trips or diagnostic failures.

Especially avoid installing safety relays above variable frequency drives or other high-heat devices; adequate cooling space must be reserved. Pilz’s installation guides and wiring diagrams clearly mark these critical points, and engineers must follow them precisely.

2. Wiring Phase: Redundancy and Isolation Determine Reliability

Wiring is the “skeleton” of a safety system; any minor mistake may lead to failure. Key points include:

1) Power Supply and Grounding

• Power must be stable and clean to avoid affecting relay operation.

• Protective grounding (PE) must be reliable to ensure equipment and personnel safety.

2) Dual-Channel Emergency Stop Redundancy

Emergency stop buttons must use two independent normally closed contacts, wired to two channels. Recommended wiring:

• Separate routing for the two signal lines

• Or use a dual-core shielded cable

• Avoid a single fault affecting both channels

If SCD is enabled, wiring must strictly follow the diagram, as any parallel connection will disable diagnostics.

3) Output and Feedback Loop

Safety contacts cut power, while feedback loops (such as Y1-Y2) verify whether the contactor has actually opened. The feedback loop must be connected in series with the contactor’s normally closed auxiliary contact to form closed-loop monitoring.

4) Reset Circuit Must Be Correct

The reset button must be connected to the designated terminals; do not short the reset circuit. Shorting disables manual reset and breaks the safety confirmation mechanism.

3. Commissioning Phase: Functional Verification and Destructive Testing Are Both Required

After wiring is complete, commissioning is the key step to verify whether the safety system is truly effective. The following process is recommended:

1) Pre-Power-On Checks

• Visually inspect wiring for looseness or potential short circuits

• Use a multimeter to test continuity and eliminate wiring errors

2) Basic Functional Testing

When conditions are met (such as emergency stop reset and safety gate closed), pressing reset should energize the relay and power the load.

3) Destructive Testing (Core Acceptance Content)

• Emergency stop trigger test: Press the emergency stop; the load must cut off immediately.

• SCD short-circuit test: Simulate a short between S11 and S21. The relay with SCD should refuse to reset or alarm.

• Feedback disconnection test: Simulate feedback line disconnection; the system should enter a fault state.

4) Parameter Settings and Records

For programmable or configurable devices, set parameters such as reset mode and delay according to requirements, and archive the settings.

As the HVAC and industrial refrigeration sectors continue to grow, the accurate detection of refrigerant leaks has become a critical component of equipment safety, energy efficiency, and environmental protection. Even minor leaks can reduce operational efficiency, compromise cooling performance, and pose environmental and safety hazards. Therefore, selecting the right refrigerant sensor is a key concern for engineers and facility managers.

The market offers a wide variety of sensor technologies, including semiconductor, electrochemical, thermal conductivity, ultrasonic, NDIR (Non-Dispersive Infrared), and photoacoustic spectroscopy. This variety often leaves users wondering how to balance performance, cost, and reliability effectively.

Sweden-based Senseair, a pioneer in NDIR gas sensing technology, leverages over thirty years of field experience and data to summarize five critical criteria for refrigerant sensor selection: cross-sensitivity, self-diagnostics, chemical aging and poisoning, environmental adaptability, and technology and supplier reliability. This guide aims to help companies make informed decisions that ensure safe and efficient operations.

1. Understanding NDIR Technology and Its Advantages

At the core of refrigerant sensor performance is the detection principle. NDIR sensors measure the absorption of specific infrared wavelengths by target gases, providing a non-contact, physics-based detection method. Compared to semiconductor or electrochemical sensors, NDIR technology offers several distinct advantages:

• High selectivity: Specific absorption wavelengths reduce interference from non-target gases.

• Long-term stability: Physical measurement principles prevent chemical aging and reduce susceptibility to poisoning.

• Wide dynamic range: Capable of detecting both trace leaks and high concentrations for alarm conditions.

Senseair’s NDIR sensors are optimized in terms of light source, detector, and signal processing, delivering highly accurate refrigerant detection while minimizing false alarms and missed detections.

2. Cross-Sensitivity: Ensuring Accurate Measurements

Cross-sensitivity occurs when sensors respond not only to target refrigerants but also to other gases. This can lead to:

• Positive interference: Carbon dioxide or water vapor may increase readings, resulting in false alarms.

• Negative interference: Methane, helium, or other gases may suppress sensor signals, creating missed detection risks.

Selection Strategy:

• Request comprehensive cross-sensitivity test reports.

• Conduct laboratory and field tests to verify real-world performance.

Senseair NDIR sensors minimize cross-sensitivity using spectral optimization and advanced signal compensation algorithms, ensuring reliable measurements in diverse conditions.

3. Self-Diagnostics: Monitoring Sensor Health

Active sensors with self-diagnostic capabilities provide real-time monitoring of their own status. They detect drift, aging, or abnormal signals and issue alerts promptly. Sensors without self-diagnostics require additional monitoring infrastructure, increasing operational complexity and maintenance costs.

Senseair NDIR sensors include comprehensive diagnostic logic to monitor drift, power anomalies, and environmental interferences, guaranteeing data reliability throughout the sensor’s lifecycle.

4. Chemical Aging and Poisoning: Ensuring Long-Term Reliability

Sensors based on chemical reactions or adsorption mechanisms, such as electrochemical or semiconductor sensors, are susceptible to aging over time. Exposure to unintended chemical substances may also lead to sensor poisoning, permanently reducing sensitivity.

Selection Recommendations:

• Consider expected lifespan and calibration intervals.

• In complex or unknown environments, prioritize NDIR sensors such as Senseair, which provide robust long-term stability and resistance to chemical interference.

5. Environmental Adaptability: From Lab to Field

While laboratory tests provide controlled data, real-world conditions are far more challenging. Dust, vibration, temperature fluctuations, condensation, water vapor, residual chemicals, electromagnetic interference, and acoustic noise can all affect sensor performance.

Senseair NDIR sensors undergo rigorous environmental testing, including high/low temperature cycling, vibration, condensation resistance, and humidity tolerance, ensuring stable performance under diverse operational conditions. Field verification is recommended to confirm suitability for specific applications.

6. Supplier Reliability: Choosing a Long-Term Partner

Sensor selection is not only about technology but also about establishing a reliable partnership. Proven technology provides extensive field data, well-defined performance boundaries, and consistent reliability. Senseair, with more than three decades of NDIR expertise, continues to invest in research and development while offering full lifecycle support. This ensures that clients receive technical guidance, data support, and product upgrades over the long term, reducing operational risks and maintenance costs.

7. Industry Applications and Benefits
