Pilz Safety System Installation and Commissioning Guide: From Environment Assessment to Short-Circuit Diagnostics

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.

Senseair Refrigerant Sensors: Five Key Selection Criteria to Prevent False Alarms and Missed Detections in HVAC and Industrial Systems

In modern refrigeration, heating, ventilation, and air conditioning (HVAC) systems, as well as industrial equipment, refrigerant leaks are more than just an energy efficiency issue—they pose serious environmental and safety risks. Even small leaks can reduce system performance, increase operating costs, and cause environmental pollution. Therefore, choosing a reliable, accurate, and environment-appropriate refrigerant sensor is critical.

With the market offering a wide variety of sensor technologies—including semiconductor, electrochemical, thermal conductivity, ultrasonic, NDIR (Non-Dispersive Infrared), and photoacoustic spectroscopy—users often struggle to balance performance, cost, and reliability when selecting sensors.

Sweden-based Senseair, with over thirty years of experience in gas sensing technology, has summarized the five key considerations for refrigerant sensor selection. These factors cover cross-sensitivity, self-diagnostics, chemical aging and poisoning, environmental adaptability, and technology and supplier reliability, providing industry professionals with a clear and practical guide.


1. Cross-Sensitivity: Preventing False Alarms and Missed Detections

Most sensor technologies are not exclusively responsive to a target gas; they exhibit some degree of cross-sensitivity to other gases. For instance, sensors based on thermal conductivity or ultrasonic principles respond to multiple unrelated gases. They often require humidity compensation to avoid interference from water vapor, which can significantly reduce stability.

  • Positive interference: For example, carbon dioxide can elevate readings, increasing the risk of false alarms.

  • Negative interference: Gases such as methane or helium may suppress the sensor signal, increasing the risk of missed detections.

Selection Tip: Request detailed cross-sensitivity test reports from suppliers. A simple breath test or simulated gas exposure can provide an intuitive check of a sensor’s interference resistance. Senseair’s NDIR sensors are designed to minimize cross-sensitivity, effectively reducing false alarms and missed detections.


2. Self-Diagnostics: Ensuring Sensor Reliability

Sensors can be either passive or active. Active sensors often feature self-diagnostic functions, monitoring their own status and reporting faults in real time. This capability increases the credibility of measurement data.

Sensors without self-diagnostic capabilities require additional monitoring mechanisms, which increase operational complexity and risk. Senseair’s active NDIR sensors provide comprehensive self-diagnostics, covering drift detection, fault conditions, and sensor health, ensuring accurate, reliable measurements.


3. Chemical Aging and Poisoning: Long-Term Stability

Sensors relying on chemical reactions, bonds, or chemical energy may experience aging, which alters sensitivity over time. Environmental exposure greatly affects the rate of aging and is difficult to predict. Chemical sensors are also prone to poisoning, where unintended substances in the air can permanently or severely reduce sensitivity.

Selection Tip: Verify sensor lifespan and calibration intervals. In complex or unknown gas environments, prioritize physical NDIR sensors like Senseair, which offer superior long-term stability and resistance to poisoning.


4. Real-World Environment Performance

Lab conditions are clean and controlled, but actual applications are diverse. Dust, vibration, temperature fluctuations, condensation, residual cleaning chemicals, electromagnetic interference, and acoustic noise can all affect sensor performance.

Selection Tip: Conduct on-site tests and simulations under real application conditions. Senseair sensors undergo extensive environmental testing, including high/low-temperature cycling, vibration, and condensation resistance, ensuring consistent performance in the field.


5. Technology and Supplier Reliability: Choosing a Trusted Partner


Conclusion

Selecting a refrigerant sensor is a systematic process that impacts long-term safety, costs, and environmental responsibility. Senseair offers a complete solution based on high-performance NDIR technology, intelligent self-diagnostics, long-term stability, and rigorous environmental validation. By choosing sensors wisely, companies can reduce false alarms, prevent missed detections, optimize energy efficiency, and ensure safe, sustainable operations in HVAC and industrial systems.

Sensor selection is not only about technology but also about partnering with a reliable supplier. Mature technology brings extensive field data, defined operating conditions, and proven reliability. Senseair, with over three decades of NDIR expertise, provides verified technology, continuous R&D investment, and full lifecycle support—making it a safe choice for long-term collaboration.

In-Depth Report | Protecting People in Noise and Steam: How BOMAG Rethought Collision Prevention for Tandem Rollers

Road construction sites are among the most demanding work environments in the industrial world. High traffic volumes, confined spaces, multiple machines operating simultaneously, and extreme environmental conditions combine to create a constant risk scenario.

For operators of heavy tandem rollers, safety depends not only on experience but also on the reliability of the machine systems that support them. Recognizing this reality, BOMAG has fundamentally redefined how collision prevention should work in modern road construction equipment.

The Invisible Burden on Machine Operators

Operating a tandem roller requires sustained concentration over long shifts. In addition to guiding the machine with high precision, operators must monitor numerous process parameters while remaining alert to changes in their surroundings.

Scientific studies have shown that prolonged exposure to noise, heat, and visual stress significantly reduces reaction times. These effects often go unnoticed until a critical situation occurs.

Why Traditional Camera Systems Fall Short

Camera-based assistance systems have long been considered standard safety equipment. However, real-world use has revealed their limitations. Visual systems are vulnerable to environmental disturbances and require constant attention from the operator.

Frequent warnings, especially in complex construction scenarios, can lead to alarm fatigue—reducing rather than enhancing safety.

BOMAG therefore asked a fundamental question: What if the machine itself could recognize danger and act autonomously?

The collaboration between BOMAG and SICK began as early as 2019, when both companies explored automation concepts for road construction machinery. The ROBOMAG research project, presented at BAUMA, demonstrated the potential of LiDAR-based perception for autonomous operation.

Building on this foundation, Emergency Brake Assist was developed as a production-ready safety system for heavy tandem rollers.

Understanding Risk Through Intelligent Algorithms

Emergency Brake Assist does not simply detect obstacles—it interprets risk. By combining LiDAR data with machine dynamics, the system predicts the roller’s future path and evaluates whether an obstacle is truly dangerous.

Only when a real collision risk exists does the system intervene by applying adaptive braking. This intelligent selectivity ensures high operator acceptance and minimal disruption to work processes.

Certified Safety and Practical Reliability

The system complies with EN ISO 13849-1 and achieves Performance Level b (PLb). It has also undergone extensive testing according to GS-BAU-70 requirements, confirming its reliability under real construction site conditions.

Collaboration as a Success Factor

Close cooperation between BOMAG and SICK played a decisive role in the project’s success. Continuous feedback from field tests enabled rapid optimization, including the development of software filters to handle steam and spray interference.

A New Safety Paradigm

Emergency Brake Assist represents more than a technical upgrade—it marks a shift from reactive to proactive safety. Instead of relying solely on operator vigilance, the machine actively contributes to accident prevention.

With its introduction on the BW 154 AP-5 and BW 174 AP-5 models, BOMAG has set a new benchmark for safety in road construction machinery.
