Yokogawa K9400VZ Detailed Wiring & Air Pipeline Connection Instructions
1. 24VDC Power Electrical Wiring
Terminal V+: Positive pole of 24VDC DC control power supply
Terminal V-: DC power supply negative pole & signal common ground
PE Terminal: Protective earth terminal, must connect instrument cabinet equipotential grounding busbar
Wiring requirement: Adopt shielded two-core cable; shielding layer single end grounding on cabinet side, separate wiring layout from instrument high-voltage power line.
2. Compressed Air Pipeline Connection (Core Pneumatic Connection)
a. High-pressure Dry Air Inlet Port: Connect factory purified instrument air pipeline via 1/4 inch NPT thread fitting, install filter pressure reducing valve before inlet port
b. Cold Air Output Outlet: Connect chromatographic column oven and sample gas pipeline constant temperature air channel with high-temperature resistant PTFE air pipe
c. Hot Air Exhaust Outlet: Discharge hot waste air out of instrument cabinet, avoid hot air reflux causing temperature interference
3. Fault Signal Dry Contact Wiring
Normally open passive alarm contact terminals: Access PLC/DCS digital input channel, transmit air supply abnormality, ultra-low temperature fault remote alarm signal to upper control system.
Wiring & Pipeline Operation Specifications
All electrical wiring and air pipeline installation must be operated under equipment power-off and air supply cut-off state; air pipeline avoids sharp bending and extrusion preventing airflow blockage; all thread joints apply high-temperature resistant thread sealant for air leakage prevention.
