IP67 Safety Digital I/O Modules
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:
Test Output Process Value
Muting Lamp Physical State
Muting Lamp Status
Step #1: 1 = ON
Lamp good
1
Step #2: 1 = ON
Lamp broken
0
Step #3: 0 = OFF
Lamp broken
0
Step #4: 0 = OFF
Lamp replaced
1
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
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)
