Debugging: Calibrate zero position and stroke range before operation; set PI control parameters.
Operation: Monitor position feedback data; ensure hydraulic actuator operates smoothly without jitter.
Maintenance: Regularly clean surface dust; check sensor line tightness every six months.
4. Important Precautions
Do not install in humid, condensed water, dusty and corrosive gas environments.
Keep away from strong magnetic interference to avoid LVDT signal drift.
Cut off all power supply before wiring, disassembly and maintenance.
Prohibit over-range driving current to prevent servo coil burnout.
Avoid severe vibration and mechanical impact during transportation and installation.
Ensure cabinet ventilation to prevent temperature drift of position accuracy.
Unauthorized disassembly of internal components is strictly prohibited.
