The SECM70 is part of an engine management system for mobile industrial (forklift) and stationary (genset) applications.

This may include 4 and 6 cylinder 4 stroke LPG/gasoline forklift applications, as well as 4 and 6 cylinder 4 stroke genset applications.

It is capable of fully authorized digital engine control including fuel, spark and air delivery.

Features and Functions

The SECM70 is part of the MotoHawk® family of control solutions. These products allow for rapid development of control systems.

The combination of off-the-shelf hardware and MotoHawk software allows developers to focus on the operational details of the application without worrying about the design details of the hardware.

The result is that the same hardware used in development and prototyping can be used in ongoing production.

The unit offers 70 connector pins with inputs, outputs and communication interfaces to support a wide variety of applications.

The SECM70 MY17 hardware can be calibrated in real-time www.abb-drive.com using MotoTune®, ToolKit, or commercially available calibration applications.

The 8923-2588 includes the 1751-6773 module and mounting kit.

Applications

The SECM70 control platform is suitable for a variety of applications including gasoline and natural gas engines for power generation, forklifts, forklifts, and on-highway vehicles.

The SECM70 control system is programmed to meet the specific needs of prime movers and the loads they drive.

At the heart of the SECM70 control system is a powerful 32-bit ST SPC563M64 microprocessor running Woodward’s ControlCore operating system.

Application programming is done through Woodward’s MotoHawk application software tool.

MotoHawk is a rapid control system development tool that allows control engineers to quickly create control software directly in Simulink diagrams.

MotoHawk is a rapid control system development tool that allows control engineers to quickly create control software directly in Simulink diagrams and run it on any MotoHawk enabled electronic control module.

Working directly in the Simulink environment, application developers can turn application models into files that can be programmed directly into Woodward production hardware in a single build step.

MotoHawk provides an advanced programming environment for users with control system expertise but not necessarily specific embedded programming skills.

Once the application is generated and loaded into the SECM70 controller via the CAN port, users can view variables and adjust controls using appropriate service interface tools such as Woodward’s ToolKit or MotoTune.

Connectivity to other devices, such as diagnostic tools, can be accomplished through additional CAN ports on the controller. The required information flow can be programmed into the controller via MotoTune or ToolKit.

The SECM70 controller consists of a rigid printed circuit board that is attached to an aluminum housing with thermal adhesive.

It is then closed and sealed with an aluminum cover. Connection to the controller is made through a single 70-pin automotive style sealed connector. The controller can be mounted directly to the engine or frame using vibration isolators pre-installed on the controller or supplied separately.
