Overview Manuals Controller I/O Breaker Control Communications Panel Setup

Features:

  • easYgen-3500-5/P1 front-panel genset controller
  • 5 A current-transformer inputs with configurable I/O
  • CANopen, J1939 and Modbus RTU communication
Woodward 8440-1934 combines the easYgen-3500-5/P1 controller, color display and 5 A current-input option in one front-panel unit.

The configurable inputs and outputs on 8440-1934 handle alarm states, analog measurements and programmed control actions.

Three CAN interfaces and the RS-232/RS-485 path separate CANopen or J1939 traffic from Modbus RTU communication on 8440-1934.

The Woodward 8440-1934 easYgen-3500-5/P1 Front-Panel Genset Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Woodward 8440-1934 is the easYgen-3500-5/P1 genset controller, combining a front-panel color display with 5 A current-transformer inputs for generator, mains and breaker-control functions.

Package P1 on 8440-1934 provides twelve configurable alarm inputs, up to twelve configurable outputs, three flexible analog inputs and two analog outputs. These channels let the controller receive engine and electrical conditions while driving the programmed operating sequence.

Communication on 8440-1934 is divided among three configurable CAN interfaces and one RS-232/RS-485 Modbus RTU path. The same control stores 300 timestamped events, so operating changes and protection responses can be reviewed against the real-time clock.

For installation, 8440-1934 uses the plastic front-panel housing measuring 282 × 217 × 99 mm. Its 8–40 V DC supply range serves 12 V and 24 V systems, while the documented maximum device weight is 2.17 kg.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which identity checks prevent Woodward 8440-1934 from being confused with another easYgen-3500 variant?
Woodward 8440-1934 is the easYgen-3500-5/P1 front-panel version with 5 A current-transformer inputs; confirm both 5/P1 and the 5 A input option.
When allocating alarm wiring, why can Woodward 8440-1934 not treat all twelve inputs as freely assignable?
Woodward 8440-1934 has twelve configurable alarm inputs, but only nine are described as freely configurable, so the remaining input roles must be preserved in the I/O plan.
Which communication duties can be separated across Woodward 8440-1934 interfaces?
Three configurable CAN ports on Woodward 8440-1934 carry CANopen or J1939 traffic, while its RS-232 and RS-485 path serves Modbus RTU slave communication.
How should analog sensing and analog commands be divided on Woodward 8440-1934?
Woodward 8440-1934 receives three configurable FlexIn analog channels and provides two configurable analog outputs, so measurement sources and commanded outputs require separate channel assignments.
Why should the real-time clock be checked when reviewing a Woodward 8440-1934 event history?
The 300-entry recorder in Woodward 8440-1934 timestamps operating and protection events with its battery-backed real-time clock, allowing sequence review only when clock time is valid.
