Problem: Signal asynchrony (such as delay) or single-channel failure (broken wire, sensor failure), leading to false shutdown or missed detection.
Cause: Loose/oxidized wiring; Different sensor response; Electromagnetic interference (EMI).
Solution:
Tighten wiring symmetrically: Use crimp terminals, check torque monthly, and apply conductive paste to prevent oxidation;
Choose models with self-diagnosis function (such as CYNDAR series SRC106 indicator) and real-time alarm function;
Anti-interference: The distance between signal line and power line is ≥30cm, the shielded line is grounded at one end, and it is far away from strong interference sources.
