Wiring specifications and scene adaptation

Core wiring requirements

DC connection: The equipment power circuit needs to be connected in series with a 2A slow melting fuse to prevent high voltage damage to the equipment;

Digital input: All digital inputs are bidirectional optocoupler type, only mode switching and testing inputs support pulse signals, and the rest are fixed signals;

Circuit breaker configuration: Supports three types of circuit breakers: pulse type, continuous type, and compact type. The output terminals need to be configured through PC utility software;

Charger generator connection: Two feedback methods are available - D+terminal connected to terminal 12, or W terminal connected to speed input terminal. The 12V system is equipped with a 47 Ω 4W excitation resistor, and the 24V system is equipped with a 100 Ω 6W resistor.

Typical wiring scenarios

The device supports multi scenario wiring, with the following core scenarios:

Scene sub model, wiring type, core usage

Independent power supply for AGC 112 three-phase/single-phase/phase separated generator set operating on an isolated island, without mains connection

AMF (mains power failure switching) AGC 113 automatically starts the generator set for power supply in case of three-phase/single-phase/phase separated mains power failure

Power management AGC 145/146 three-phase with mains circuit breaker (145) or mains+contact circuit breaker (146) management

Communication Configuration Specification

Communication Protocol and Interface

Modbus RTU/ASCII: supports communication with PLC and other devices through RS485 interface (terminals 49-51);

CAN bus: The CAN J1939 protocol (terminals 53-55) is used for engine communication, and terminals 57-59 are used to connect to the AOP-2 operator panel or external I/O module (Option H8).

Requirements for communication cables

Cable type: Belden 3106A or equivalent shielded twisted pair, 22AWG (0.324mm ²), shielding coverage rate ≥ 95%;

Communication distance: maximum 300m. When the bus length exceeds 30m, a 120 Ω terminal resistor needs to be installed;

Shielding treatment: Ensure effective grounding of the shielding layer to reduce electromagnetic interference.

Extended Configuration

External I/O module: needs to be used in conjunction with AOP-2 panel, with a total terminal resistance of 120 Ω;

AOP-2 operator panel: equipped with DC-DC converter and 2 1m cables (one end RJ12, one end stripped), with a maximum communication distance of 300m.
