Woodward ProAct ISC Integrated Speed Control

ProAct™ ISC combines the proven ProAct electric actuator with integrated speed control software to control the speed of diesel and gaseous fuel engines. ProAct ISC is a microprocessor-based speed control incorporated into an actuator, creating a single integrated actuator/speed control. This eliminates the need for an additional driver box and speed control box.

ProAct ISC can also be configured as a position control only device for basic actuator applications, accepting 4–20 mA, 0–5V, -3V to +3V, or CAN position command signals.

The ProAct ISC control uses state-of-the-art speed sensing and control algorithms. It also performs comprehensive diagnostics for easy troubleshooting. The ProAct ISC is configured and tuned using the ProAct ISC Service Tool.

The modular bi-directional actuator design easily attaches to fuel pumps, fuel valves, or throttle bodies.

Features include:

  • Extremely fast, bi-directional electric actuator, electronically positioned in both directions
  • All-electric actuator requires no drive or hydraulic supply

Woodward ActiVGen Engine Speed Control

Woodward’s actiVgen engine speed control is designed specifically for use on Caterpillar diesel engines equipped with ADEM electronic control modules, and can markedly improve the transient response of Caterpillar generators in load-sharing applications.

The actiVgen control does not replace the ADEM control; rather it is used as a separate, external primary speed control with user-configurable PID settings. The actiVgen control gives the user full access to tune the Caterpillar engine directly (rather than needing a Cat technician to make tuning changes in the ADEM module), which can save time and expense during commissioning. The actiVgen control frees the user to make regular "maintenance" tuning adjustments over time to maintain optimum system performance as operating conditions change.

Features include:

  • Ability to take control of commissioning Cat® ADEMTM-equipped gensets
  • Improved steady-state and transient dynamics in load-sharing systems
  • Full user access to primary speed control PID settings for optimal tuning
  • Decrease commissioning time and expense
  • CAN/J1939 bus interface with secondary paralleling genset controllers, such as the easYgen™ control
  • Isochronous speed control
  • Easy access to PID settings with ToolKit calibration software

Woodward APECS 500 Single Speed Electronic Engine Controller

Woodward’s Advanced Proportional Engine Controls System (APECS) provides isochronous or multi-speed engine governing through a wide speed range. The complete system consists of a powerful microprocessor-based controller driving a precision proportional actuator. The actuator is connected to the engine’s throttle or fuel pump speed lever to precisely control engine speed.

The APECS 500 controller combines the convenience of manual adjustments with the flexibility of a computer-based calibration tool. Electrical connections consist of six wires to battery, actuator and magnetic engine speed pickup. For most applications, APECS 500 can be connected and adjusted with simple hand tools. This single speed controller is designed to meet the needs of the small genset market where simplicity, ease of operation, and low cost are key features.

The APECS 4500 controller is integrated into commercial and construction vehicles, and industrial engine systems and compressors by original equipment manufacturers and industrial plants. It is also suitable for low speed (< 25 km/h [16 mph]) non-consumer off-highway vehicles. Typical applications include generator sets, compressors, construction machinery, and farm vehicles.

Woodward APECS 4800 Control System

The APECS 4800 control system combines a digital electronic controller with a rotary or linear actuator to provide speed control of diesel engines under 75 hp (56 kW). The system provides accurate, reliable, and durable control over the service life of the engine in the extreme operating environments found in power generation and industrial applications.

The 48-pin digital controller provides isochronous speed control, actuator position control, torque limiting, droop, glow plug control, CAN J1939-based communications, and additional engine management and protection functions to optimize engine operating efficiency.

Typical applications include stationary and mobile generator sets, construction machinery, and farm vehicles.
