Safety Node B Internal Fault

¿Qué significa STAS2 Flashing ?

The STAS2 (Safety node B) Orange LED is flashing at a rate other than 1 Hz (normal) or 10 Hz (boot phase), indicating an internal fault code within Safety Node B. This suggests a problem with the internal logic, communication, or processing of this safety node, potentially affecting safety chain integrity and preventing safe operation.

• The Safety Node B (STAS2) microcontroller is experiencing an internal fault, indicated by flashing.
• Internal error within the STAS2 safety device.
• The STAS2 safety processor has detected a critical internal failure.

1. 1

   Check cabling at connectors X309, X310, and X312 for proper connection, integrity, and any signs of damage.

2. 2

   For test purposes, disconnect the cables at X309, X310, and X312, then switch the controller off and back on again to reset the module.

3. 3

   If the error recurs after checking cabling and power cycling, exchange the CCU_SR module.
