Yk 331-02430-601 Main Control Board: Core Functions
1. System Master Control (Core Unit)
Acquires key parameters such as evaporation/condensation pressure, chilled/cooling water temperature, oil temperature, oil pressure, vibration levels, and liquid levels;
Executes closed-loop control for compressor speed, inlet guide vane (IGV) opening, capacity modulation, and start/stop logic;
Implements safety interlocks including anti-surge protection, oil pressure protection, high-temperature protection, vibration protection, and water flow protection.
2. OptiView System Communication and Display
Communicates in real-time with the York OptiView operator panel to display operating parameters, fault codes, historical records, and trend curves;
Supports remote monitoring, parameter configuration, software updates, and fault diagnostics.
3. Precision Compressor Control
Start-up Control: Soft start, Star-Delta switching, pre-opening of guide vanes, and oil pressure establishment;
Operational Modulation: Infinitely adjusts guide vane opening based on cooling demand to ensure efficient and stable operation;
Shutdown Protection: Normal shutdown, emergency shutdown, anti-reverse rotation protection, oil recovery, and refrigerant equalization.
4. Fault Diagnostics and Protection
Monitors over 200 operating parameters in real-time to accurately identify faults and store historical records;
Protective Actions: Immediate shutdown, alarm output, fault lockout, and prevention of secondary damage.

Key Points for Product Installation and Replacement
1. Power Disconnection and Discharge: Before replacement, cut off the unit’s main power supply and control power supply, and allow for a discharge period of at least 10 minutes to prevent high-voltage electric shock and electrostatic damage to the mainboard.
2. Wiring Standards:
Record the numbers and sequence of all wiring terminals, and take photographs for reference;
Apply even force when inserting or removing connectors to avoid bending or breaking the pins;
Strictly distinguish between power cables and communication cables, and ensure the shielding layers are reliably grounded.
3. Software and Compatibility:
The new mainboard comes pre-loaded with the specific software program corresponding to the unit model; it will automatically detect and identify the unit’s configuration after installation;
For certain models, it is necessary to verify the mainboard model, serial number, and software version via the OptiView control panel.
4. Grounding and Interference Suppression:
Ensure the mainboard is reliably grounded to prevent electromagnetic interference;
Keep the mainboard away from variable frequency drives (VFDs), contactors, and high-power equipment, and maintain adequate clearance for heat dissipation.
5. Commissioning and Verification:
After powering on the unit, check the status of all indicator lights, verify communication connections, and confirm parameter displays;
Perform test runs under both no-load and full-load conditions to verify the proper operation of compressor start/stop cycles, inlet guide vane control, safety protection functions, and communication links.
