배선, Commissioning and Troubleshooting Guide (SICK WT160-F410 / 6022788)

배선 단계
Brown wire (핀 1) to DC10~30V+, 파란색 와이어 (핀 2) to 0V. Verify voltage before power-up. AC supply and reverse polarity are forbidden.
Black wire (핀 3) for PNP output: Output voltage approximates supply voltage when target is detected. White wire (핀 4) remains unconnected; do not short-circuit.
딥스위치:

L/D: Light-on / Dark-on selection

Factory default: Light-on. Output activates when an object enters the sensing zone.

PLC wiring for PNP: Connect black wire to PLC input terminal; PLC common terminal to 0V.

LED Indicator Description:

Green LED: Steady ON = Power OK; Green OFF = No power or open circuit

노란색 LED: Sensing indicator; Yellow ON = Target detected

Comissioning Guide (Focus on BGS Background Suppression)

감지 범위: 4–60 mm. Avoid mounting target closer than 4 mm (risk of false triggering). 8–50 mm is the preferred stable working zone.
BGS characteristic: Only detects objects within the set distance; metal frames, conveyor belts and other rear backgrounds will not trigger the sensor.

✅ Commissioning verification method:

① Place target workpiece, yellow LED lights up;

② Remove workpiece, yellow LED turns off;

③ Keep workpiece in place and move background plate closer to the sensor. If yellow LED status stays unchanged, background suppression works properly.

Light spot: Small red spot, suitable for tiny workpieces. For highly reflective bright metal parts, increase distance appropriately to avoid saturation and false triggering.
설치: Keep optical window free of oil, dust and coolant. Prevent direct strong light exposure (햇빛, high-power light sources).
문제 해결 표

징후	Check Items
녹색 LED 꺼짐	Insufficient supply voltage, reversed brown/blue wiring, 끊어진 케이블, loose pins in M8 connector
Green LED ON, yellow LED always ON (no target present)	Background too close, highly reflective background, dirty lens, DIP switch set to Dark-on, internal optical failure
Green LED ON, yellow LED does not light with target present	Beyond maximum sensing range, dark high-absorption target, spot misaligned on workpiece, lens blocked
Yellow LED flickering, unstable signal	Excessive supply ripple, long cable with interference, loose mounting causing vibration, target at sensing boundary
Output intermittent while yellow LED works normally	Incorrect PLC wiring, shorted output load, PNP output overcurrent (max load current 100 엄마)

제한사항 & 메모
Max output current: 100 엄마. Do not drive solenoid valves or high-power relays directly; 중간 릴레이를 사용.
IP67: Only protected against temporary splash water. Not for permanent immersion. Extra protection required for coolant or oil mist environments.
Discontinued model: Higher risk of optical drift and unstable signal with aging. Replace with WT160-F420 once instability occurs.

General Diffuse vs BGS Background Suppression Diffuse (WT160-F410 type)

BGS versions are preferred for cluttered backgrounds prone to false triggering.

✅ Selection Guide for Drawing

Standard diffuse (without BGS) – Suitable for single, distant clean backgrounds. 저렴한 비용. Strongly affected by target color and reflectivity; black targets may fail detection.
BGS Background Suppression Diffuse (WT160-F410) – Triangulation principle. Only detects objects within the target distance and shields rear frames, conveyors and metal backgrounds. Suitable for short-range, cluttered background applications where workpieces sit close to conveyors; widely used in custom automation.

❌ Unsuitable Applications

장거리 감지 (>1 중; through-beam or retro-reflective preferred)

Highly transparent objects (transparent films, glass bottles; unstable for standard diffuse sensors)

Mirror-like highly reflective workpieces (easy saturation and false trigger)

Direct strong sunlight, heavy dust or heavy coolant splash without shielding

Safety protection circuits (not safety-rated sensors)
