BNI CIP-351-000-K015
Safe I/O Module, EtherNet/IP™ CIP Safety™
IP67 Module
When test output is activated, Muting Lamp feature controls the output current. Below 5mA, a fault is
detected and the status is 0=OFF. Above 25mA is normal operation, the status is 1=ON.
Below is a typical scenario for muting lamp broken wire detection:

Typical wiring of safety inputs
M12 pining and wiring of the safety inputs with the associated pulse test outputs
• 1: Test Output #1 (TP1, 24 VDC powered from UB)
2: Safe Input #1 (IN1)
•
3: Ground Logic/Input (UB GND)
•
4: Safe Input #0 (IN0)
•
5: Test Output #0 (TP0, 24 VDC powered from UB)

Muting Lamp Physical State
1 = ON
1 = ON
0 = OFF
0 = OFF
Notes!
• Only Test Output 3 and Test Output 7 can be configured in Muting Lamp
mode.
• When Test Output is not activated, no broken wire fault can be detected.
However, once a default has been detected (step 2), the lamp
replacement is diagnosed even if the Test Output is deactivated (step 3)
• Broken wire detection is performed at a 3 second period. Two
consecutive detections are required before the status is reported as BAD,
so up to 6 seconds can be required before muting lamp status to be set to
BAD
