XVS Series Photoelectric Sensor Debugging Procedure
Model: XVS-440-10MF1-1-1U (PNP, NO, M18 Thread, IP67)
Pre-Debugging Checklist
plaintextCopy Code
[ ] Verify power: 10-30V DC (ripple ≤10%)
[ ] Confirm wiring:
• Brown: 24V+
• Blue: 0V-
• Black: Load output
• Gray: Teach-in input
[ ] Ensure optical path clearance (no reflective surfaces <50mm)
[ ] Check ambient conditions:
• Temperature: -25°C to +55°C
• Humidity: ≤95% non-condensing
• EMI shielding: ≥30dB attenuation required

Debugging Sequence
Step 1: Power-On Diagnostics
multimeterCopy Code
1. Apply voltage: Measure between Brown(+) and Blue(-) = 24V DC ±10%
2. Dark state output:
- NO model: V_out = 0.8V max (load OFF)
3. LED indicators:
• Green POWER: Solid = OK
• Yellow STATUS: 1Hz blink = Operational
Step 2: Teach-In Mode
procedureCopy Code
1. Trigger teach-in:
- Method A: Apply 5-30V DC to Gray wire for 3s
- Method B: Use Baumer BTM 2000 programmer
2. Confirm success:
• STATUS LED blinks 3x rapidly
• Output toggles on object detection
3. Sensitivity adjustment:
• Rotate pot (CW↑ sensitivity / CCW↓ sensitivity)
• Optimal range: 40-80% of scale

Step 3: Dynamic Response Test
test_parametersCopy Code
Test Object: DIN ISO 9403 Type A (50x50mm white ceramic)
Distance: 440mm (nominal sensing range)
Speed: Variable conveyor belt (0.1-2m/s)
[Verification Metrics]
• Response time: ≤1ms (dark→light transition)
• Hysteresis: ≤3% of sensing distance
• Repeatability: ±0.2mm @ 1kHz sampling
Advanced Calibration
For Challenging Surfaces (IR Mode):

$ btool --device XVS440 --mode calibrate
> set_wavelength(850nm)
> set_pulse_width(200µs)
> save_config(profile3)
Requires Baumer BTools software v2.4+ and USB-IFC interface
Error Diagnostics
LED Pattern | Fault | Corrective Action |
---|---|---|
POWER off | No voltage | Check polarity & fuse (min. 100mA) |
STATUS red blink (2Hz) | Saturation error | Reduce sensitivity by 25% |
Both LEDs alternating | EMI interference | Install ferrite core (Z=120Ω @ 100MHz) |
STATUS solid yellow | Teaching mode active | Cycle power or short gray wire to 0V |
