WOODWARD easYgen-3000 Series (Package P1) Genset Control

Core positioning and basic information

The Woodward easyYgen-3000 series (Package P1) generator set controller is a multifunctional control unit designed for general and marine scenarios. Manual 37223E (software version 1.10xx) serves as an exclusive installation guide, focusing on hardware installation, wiring configuration, physical parameters, and safety specifications of the equipment, without involving parameter configuration and daily operation details. The product covers four core models (8440-1816/1817/1818/1831), which have undergone multiple revisions from A to E. The main focus is on optimizing the installation instructions and correcting details of the shell, ultimately forming a complete installation guidance system. Its core value lies in providing precise electrical parameter measurement, flexible input-output control, and reliable communication interconnection for generator sets, adapting to multi scenario application needs from ordinary computer rooms to ship decks.

Hardware structure and installation specifications

1. Shell type and core parameters

The product offers two differentiated shell designs, suitable for different installation scenarios:

Shell type corresponds to model, core feature size (W × H × D), protection level, installation method

Plastic shell easyYgen-3200 with graphic LCD display screen, supports local operation 282 × 217 × 99mm fixture fixing IP54; Screw kit IP66 panel embedded installation, hole size 249 × 183mm (tolerance+1.1/+1.0mm)

Metal shell easyYgen-3100 without display screen, focusing on integrated installation 249.6 × 227.4 × 84.1mm IP20 cabinet back installation, fixed with 4 M6 screws

2. Key installation requirements

Torque control: Plastic shell screws require 0.6Nm for fixation, fixtures require 0.1Nm for fixation; metal shell and terminal wiring require 0.5Nm to avoid damage to components due to over tightening

Wiring specification: Only 60/75 ℃ copper wire is allowed, with a maximum wire diameter of 2.5mm ² (14AWG), and the terminal load capacity needs to be matched

Static electricity protection: Before contacting the circuit board, it is necessary to release human static electricity to avoid synthetic materials from approaching the equipment; The PCB board should always be in anti-static packaging and only be operated with the edge in hand

Ship scene adaptation: The metal shell directly complies with LR/ABS classification society certification; The plastic shell needs to be fixed with 12 screws and an EMI filter (such as TIMONTA FSS2-65-4/3) should be installed in the bridge/deck area

3. Terminal layout and interface distribution

The back terminals of the device are designed according to functional zoning, including the power supply area (61-65 terminals), measurement area (1-40 terminals), input/output area (41-80 terminals), and communication area (independent interface). Among them:

The protective grounding (PE) terminal 61 is only effective on plastic shell models, and the metal shell needs to be grounded through the shell to achieve protection

Centralized layout of relay output and discrete input terminals for easy wiring organization; Separate partition of analog signal terminals to reduce interference

The communication interface (RS-232/RS-485/CAN) adopts standard D-SUB/IDC interface, with reserved shielding layer connection points to enhance anti-interference capability

Core Electrical Configuration and Wiring Guide

1. Power supply system configuration

Main power supply: Supports 12/24VDC wide voltage input (8-40Vdc), with a maximum power consumption of 17W. A 6A slow melting fuse (such as NEOZEN D01 6A) or a C-type miniature circuit breaker (such as ABB S271C6) needs to be connected in series in the power supply line

Auxiliary power supply: Terminal 65 provides pre excitation output (D+) for the charging generator, which excites the generator during startup and monitors the charging voltage during operation

Grounding requirements: The voltage difference between the negative terminal of the battery and the PE terminal shall not exceed 15V, and an isolated external power source shall be used if it exceeds this limit; Ship scenarios require additional access to independent safety protection devices that comply with classification society regulations

2. Measurement system wiring (voltage/current/power)

(1) Voltage measurement (FlexRange dual range)

Supports voltage measurement for generators, power grids, and busbars, covering various wiring methods such as 1Ph 2W/3W, 3Ph 3W/4W, etc. The core specifications are as follows:

Range selection: 100V range (50-130Veff) is suitable for low voltage scenarios, 400V range (131-480Veff) is suitable for high voltage scenarios, and it is strictly prohibited to connect two sets of ranges at the same time

Wiring requirements: The generator voltage is connected through terminals 29-36, the grid voltage is connected through terminals 21-28, and the bus voltage is connected through terminals 37-40; The N line needs to be wired separately to avoid measurement errors caused by different voltage systems sharing the N terminal
