Key issue

Question 1: How is the dual circuit breaker (CBA/BBB) control function of LS-6XT implemented, and what are the core configuration differences?

Answer: The dual circuit breaker control is achieved through the “CBA/BBB mode”, and the core is the independent control and linkage logic of the two circuit breakers: ① Hardware configuration: CBA corresponds to the main circuit breaker, CBB corresponds to the backup/load circuit breaker, both support closing/opening pulse/continuous control, and can be configured with automatic unlocking (Pre open) function; ② Core differences: CBA focuses on main circuit grid connection, dead bus closure, and system A decoupling, while CBB focuses on backup circuit switching and system B associated control, with CBA having higher closure priority than CBB; ③ Linkage logic: supports load transfer (four modes), synchronous grid connection linkage (CBB synchronization after CBA closure), and selective disconnection in case of failure (such as CBA disconnection in case of system A failure and CBB disconnection in case of system B failure); ④ Configuration points: It is necessary to switch between “CBA”/”CBA/BBB” modes through parameter 9018 (Breaker mode), and configure the synchronization threshold, dead bus condition, and linkage delay of both modes separately.

Question 2: How to configure and use the extended I/O (IKD module) of LS-6XT, and what extension scenarios are supported?

Answer: The IKD module is an external I/O expansion solution, with the following core configurations and scenarios: ① Supported module types: IKD1 (8DI+8DO), IKD-IN-16 (16DI), IKD-OUT-16 (16DO), P1 model supports 2 IKDs (16DI+16DO), P2 model supports 4 IKDs (32DI+32DO); ② Connection method: Connected through CAN1 bus, CAN baud rate and module address need to be configured, shielded cable exposed length ≤ 25mm; ③ Configuration path: “Configure Input/Output → External Discrete Input/Output” in ToolKit, can set DI alarm level, delay time, and logical association of DO; ④ Extended scenarios: Suitable for complex systems that require more discrete signal acquisition (such as multi-sensor alarms) or output control (such as multi actuator linkage), such as multi loop state monitoring in ship power systems and multi device linkage control in industrial units.

Question 3: What is the core logic and safety mechanism of the synchronous grid connection and dead bus closure function of LS-6XT?

Answer: Both are the core functions of circuit breaker closure, and the logic and safety mechanism are as follows: ① Synchronous grid connection logic: Real time monitoring of dual system voltage/frequency/phase, meeting preset thresholds (voltage difference ≤ 20%, frequency difference ≤± 0.49Hz, phase difference ≤± 60 °) and continuously setting time (default 3s), triggering closure; Supports two synchronization modes: “slip frequency” and “phase matching”, which can offset transformer phase offset through phase compensation; ② Dead bus closure logic: detects that the system voltage is below the threshold (0-30% rated voltage) and has a continuous delay time (0-20s), triggering after meeting the “no other device closure request” (multi device negotiation), supporting three scenarios: A dead B dead, A dead B live, A live B dead; ③ Security mechanism: Verify phase sequence consistency (CW/CCW) before synchronous grid connection, and block closure if inconsistent; The closure of the dead bus requires the “Enable close” logic to be enabled through LogicsManager, and there should be no C/F level alarms; In multi device scenarios, using “device number priority” to avoid simultaneous closure and automatically releasing permissions after closure failure ensures system security.

Key issues

Question 1: What are the core configuration points and networking capabilities of the CAN bus interface of the easyYgen-3000 series in load sharing scenarios?

Answer: The core configuration and networking capabilities focus on three points: ① Hardware limitations: up to 32 devices can be networked, and the CAN2 interface is dedicated for load sharing, requiring configuration of transmission rate (0.10-0.30 s) and CAN-ID (2xx/3xx/4xx/5xx Hex); ② Parameter consistency: All participating devices need to have a unified baud rate (default 250 kBd), Node ID (recommended low value), and load sharing interface (default CAN1); ③ Bus load control: It is recommended that the total load not exceed 100%, which can be optimized by increasing the baud rate, reducing the frequency of visual data transmission, and disabling redundant Sync/TIME messages. Suitable for power balance allocation scenarios of small and medium-sized generator clusters.

Question 2: How to achieve remote control of generator set start stop and parameter modification in Modbus communication, and what are the key addresses and operating logic?

Answer: ① Remote start stop: Operated through Modbus address 40504 (parameter 503), Bit0 is set to 1 to start, Bit1 is set to 1 to stop, and Bit4 needs to be set to 1/reset twice to complete alarm confirmation; ② Parameter modification: Basic parameter (such as generator rated voltage) address=40000+parameter ID+1 (parameter ID<10000) or 400000+parameter ID+1 (parameter ID ≥ 10000), the corresponding interface password needs to be entered first (such as serial port 1 password parameter 10401); ③ Setpoint switching: To enable the second set of voltage/frequency/power factor/power setpoints through Bit4-7 at address 40505 (parameter 504), the setpoint source needs to be configured as “Interface” first. The operation must follow the Modbus RTU protocol and support single register (function code 06) or multi register (function code 10) writing.

Question 3: What are the adaptation capabilities and core interaction functions of the easyYgen-3000 series for J1939 ECU, and what should be noted during the adaptation process?

Answer: Adaptability and interactive functions: ① Compatibility range: Supports 10+mainstream ECUs (such as Scania S6, Deutz EMR2), which can achieve 8 core functions including engine start stop, idle control, and speed deviation adjustment (0-1400 rpm) through CAN2 interface; ② Data exchange: Collect 20+parameters such as engine speed and coolant temperature, and support DM1/DM2 fault code transmission; ③ Attention: Select the corresponding ECU model in parameter 15102 (device type). The J1939 self address (parameter 15106) defaults to 234, and the engine control address (parameter 15107) defaults to 0; Even if the ECU is not connected, if the J1939 analog input device is connected, the device type cannot be set to “Off”, and some ECUs require the manufacturer to enable remote control function.

Safety Warning and Important Reminder

Critical safety warning

Independent overspeed protection: The prime mover must be equipped with an overspeed (over temperature or over pressure) shutdown device that is completely independent of the controller to prevent equipment damage or personnel injury caused by the failure of the governor or control system.

Electrostatic protection: The electronic control unit contains electrostatic sensitive components, and before operation, body static electricity must be released by contacting the grounding surface to avoid contact with components and conductors on the printed circuit board.
