Sourcing Expansion Valve Controller from Dotech Inc. - South Korea (Republic Of Korea) Import Guide
Before ordering, verify the controller’s input signal compatibility with your building management system. Confirm whether the 0 - 10 V or 4 - 20 mA input matches your sensor output. Request a wiring diagram and check for grounding requirements. Ensure the mounting depth fits your DIN rail enclosure and that ambient temperature in the installation location stays within the rated range.
Confirm lead time, Incoterms, and packaging with the supplier. Standard shipping is FOB Busan, with lead times of 30 to 45 days. Payment terms are typically T/T or L/C. Units are usually packed in anti-static foam with individual boxes. Ask for export documentation including electrical safety compliance statement and RoHS declaration, even if not certified.
Upon receipt, inspect for physical damage, loose terminals, or signs of moisture ingress. Test the controller with a variable power supply and simulate input signals to verify proportional output. Retain a sample unit for future reference. If the unit fails to respond to signals, request a functional test report from the supplier before installation. Document the batch number for traceability in case of field failures.
