Installation & Maintenance Guide

Installation Steps:

1. Mounting: Snap modules onto a 35mm DIN rail, ensuring ≥5mm spacing for heat dissipation.
2. Wiring: Connect input (signal source), output (load), and power supply per terminal markings (use 0.14~2.5mm² conductors).
3. Torque: Tighten terminal screws to 0.5~0.8Nm (prevents vibration-induced loosening).
4. Polarity Check: For RW variants, ensure correct input/output polarity (reverse polarity protected).
5. Testing: Verify LED indicators (green = power-on, yellow = signal/count/switch active) post-installation.

Maintenance Points:

• Status Monitoring: Regularly check LEDs (red = fault) → replace modules if faults persist after troubleshooting.
• Fault Troubleshooting:
  • PLC-OPT: No signal → check wiring/polarity; slow response → confirm high-speed model selection.
  • PLC-HSC: Incorrect counting → verify signal frequency (≤10kHz) and noise filtering.
  • PLC-HPT: Load not switching → check load current (≤10A) and overheating.
• Replacement: Replace modules after 10 years of service or if housing is damaged.
• Environmental Control: Keep installation area dry (relative humidity 10~90%, non-condensing) and free of dust.
