Introduction of Safety Relay

Emergency stop relay
Welcome to DADISICK's comprehensive guide on Safety Relay Maintenance. In this webpage, we will explore the crucial aspects of maintaining Safety Relays to ensure they operate at peak performance and provide reliable protection in industrial settings. Safety relays operate on a redundant, self-monitoring circuit design. For instance, Dadisick's LS-2A4S series uses dual-channel monitoring to detect faults and safely interrupt power, even if a component fails. This ensures compliance with safety standards and protects against unexpected incidents. Our expert team at DADISICK, a leading manufacturer of industrial automation safety sensors since 2006, is dedicated to providing you with the knowledge and tools needed to maintain your safety controller effectively.

Why Module Safety Relay Maintenance Matters

Safety Relays are vital components in industrial systems, designed to monitor and control safety functions such as emergency stop signals, safety door switches, and light curtains. Proper maintenance ensures that these emergency stop relay function correctly, preventing potential hazards and downtime. According to industry standards like EN 60947-5-1 and EN 60204-1, regular maintenance is essential for the reliable operation of Safety Relays.

Regular E-stop Safety Relay Maintenance Practices

Visual and Mechanical Inspection

Conduct regular visual inspections of your emergency stop safety relay to check for any signs of damage, wear, or deformation. Look for cracks in the housing, loose parts, or any physical damage that might affect the safety control relay's performance. Mechanical components should move freely and reliably.

Insulation Resistance Measurements

Perform insulation resistance measurements to ensure the safety monitoring relay's insulation is in good condition. This test helps identify any potential insulation degradation that could lead to faults or safety hazards.

Secondary Injection Tests

Secondary injection tests are crucial for verifying the safety relay module's settings and functionality. These tests involve injecting known currents and voltages into the safety relay's secondary circuits to simulate fault conditions and ensure the safety control relay responds correctly.

Functional Testing

Test the safety relay's functionality by checking safety relay wiring, current and voltage transformers, and all auxiliary devices. This ensures that all components are working together seamlessly and that the safety monitoring relays will operate as expected in the event of an emergency.

Troubleshooting Common Issues of Safety Relay Module

Contact Faults

Contact faults are a common issue in Safety Relays. These can be caused by mechanical obstructions, welding, or environmental factors. Symptoms include inability to open or close circuits, increased contact resistance, and unstable connections. To resolve contact faults, inspect the contacts for wear, clean them if necessary, and ensure proper alignment and contact pressure. Dadisick's LS-A series includes LED indicators to quickly diagnose input/output status.

Coil Issues

Coil problems can arise from voltage surges, incorrect voltage application, or environmental factors like humidity and temperature. Signs of coil issues include burning smells, discoloration, or failure to energize. To address coil problems, verify the correct voltage is applied, check for insulation damage, and ensure the safety relay working within its specified temperature and humidity range.

Environmental Factors

Extreme temperatures, humidity, and corrosive gases can significantly impact the performance and lifespan of Safety Relays. Ensure the 2 channel safety relays are installed in environments that meet their specified operating conditions and take measures to protect them from harmful environmental factors.
