- Instalare & Wiring Guide
Etape de instalare
- Select proper mounting position to ensure reliable actuation of the actuator
- Secure the switch with M4 screws, tightening torque 0.8–1.2 N·m
- Connect wires:
NO contact: “turn on at position” in control circuit
NC contact: “turn off at position” (commonly used for emergency stop)
- Check actuation direction and reset for sensitive and reliable operation
- Power on and test to confirm normal circuit function
Note de cablare
Cable stripping length: 7–9 mm; avoid too short or too long exposed conductor
Tighten terminals securely to prevent loose connections
Distinguish AC/DC circuits; do not exceed rated voltage/current
Avoid direct control of high-power loads; use an intermediate relay if needed
- Operation & Întreţinere
- Regularly check actuator flexibility and reset performance
- Clean contact area to remove dust and oil, preventing poor contact
- Inspect wire connections for looseness caused by vibration
- Avoid overtravel and overfrequency operation to protect internal mechanism
- Replace the switch promptly if contact burning, sluggish action, etc. occur
