Seven. Precautions

The power supply must be stable at 12–24VDC. Avoid excessive voltage fluctuations that may cause counting errors; Do not reverse the power supply connection to prevent module burnout.

Pulse signals must use shielded twisted-pair cables. For long-distance transmission (>5m), prefer the differential mode. Keep away from strong interference devices to avoid signal distortion.

The working temperature should be controlled within -20℃ to +70℃. Ensure good ventilation in the cabinet during installation to avoid heat accumulation; Reduce the pulse frequency in high-temperature environments to extend module lifespan.

Regularly check the wiring terminals to prevent loosening and oxidation; Calibrate the counting accuracy once every 6 months. Shorten the calibration period in harsh environments.

The module is an electrostatic-sensitive device. During installation and maintenance, wear an anti-static wrist strap to avoid damage to internal chips due to static electricity.

The module has no user-repairable components. Faults require return to the factory for repair. Do not disassemble privately to avoid damaging the warranty label.
