Working Principle The safety controller continuously monitors all connected safety input devices for proper operation and fault conditions. When a safety device is activated or a fault is detected, the controller immediately switches off the safety outputs to remove hazardous motion. It performs continuous internal self-tests and external device monitoring to ensure the safety function remains available at all times, meeting required safety standards.

Installation Requirements

• Mount on standard 35 mm DIN rail
• Allow 30 mm clearance above and below for wiring
• Use copper conductors rated for at least 2 A
• Connect safety outputs to external contactors or relays as required
• Install in pollution degree 2 industrial environment
• Separate safety wiring from power wiring to avoid interference

Usage Notes

• Safety system must be validated by qualified safety engineer
• Do not modify safety parameters without proper authorization
• Perform regular functional tests per safety regulations
• Keep configuration backup for disaster recovery
• Do not use in explosive atmospheres unless specifically certified
• Disconnect power before servicing terminals
