Key Features & Performance Benefits

Precision Speed Regulation: Maintains engine speed within ±0.25% under varying load conditions, ensuring consistent power output and reduced fuel consumption. The advanced PID control algorithm automatically compensates for load transients and environmental variations.

Flexible Control Modes: Switch seamlessly between droop mode for parallel operation, isochronous mode for single-unit applications, and load sharing mode for multi-engine installations. This versatility makes the 1692-387 ideal for genset paralleling, cogeneration systems, and marine propulsion configurations.

Load Sharing Capability: Enables multiple engines to share electrical or mechanical loads proportionally, preventing overload conditions and optimizing fuel efficiency across your power generation fleet. The integrated load share line ensures balanced operation without external controllers.

Robust Industrial Design: Built to withstand harsh industrial environments with wide operating temperature range, vibration resistance, and EMI/RFI immunity. The sealed front panel protects against dust and moisture ingress in challenging installations.

Application Scenarios

Power Generation: Deploy the 1692-387 in standby, prime, or continuous-duty generator sets ranging from 50 kW to 3 MW. The module's fast response time (typically <100ms) ensures stable frequency control during load acceptance and rejection events, critical for sensitive electronic loads and grid-tie applications.

Marine Propulsion: Control main propulsion engines and auxiliary power units aboard commercial vessels, offshore platforms, and naval craft. The module's salt-fog resistance and shock/vibration tolerance meet stringent marine classification society requirements.

Industrial Drives: Regulate speed for mechanical drives in oil & gas compression, water pumping, material handling, and process industries. The programmable speed setpoint and remote start/stop capability integrate seamlessly with SCADA and DCS systems.

Cogeneration Systems: Coordinate engine speed with thermal and electrical load demands in combined heat and power (CHP) installations, maximizing overall system efficiency and reducing operating costs.

Integration & Compatibility

The Woodward 1692-387 interfaces directly with electronic actuators (EG-3P, EG-2000, ProAct series), magnetic pickups (MPU), and standard industrial sensors. The RS-485 Modbus RTU port enables remote monitoring and control via HMI panels, PLCs, or cloud-based asset management platforms. Configuration is performed using Woodward's GAP software suite, allowing parameter adjustment, diagnostics, and firmware updates.

For complete system solutions, pair the 1692-387 with complementary Woodward products including Bently Nevada 330400-00-00 Accelerometer for vibration monitoring, Bently Nevada 3500/45 Position Monitor for shaft displacement tracking, and Emerson EPRO PR6424/010-040 Vibration Monitoring System for comprehensive machinery protection.

Common Questions & Answers

Q: Can the 1692-387 control both diesel and natural gas engines?
A: Yes, the module is fuel-agnostic and works with diesel, natural gas, biogas, and dual-fuel engines. Speed sensing is based on crankshaft rotation via magnetic pickup, independent of fuel type.

Q: How many engines can be paralleled using load sharing mode?
A: Up to 16 engines can be paralleled on a common load share bus. Each unit requires its own 1692-387 governor with load share wiring interconnection.

Q: Is the module compatible with legacy Woodward governors?
A: The 1692-387 can replace older analog governors (2301A, UG-8, etc.) with minimal wiring changes. Consult the installation manual for specific retrofit procedures and actuator compatibility.

Q: What diagnostic capabilities are available?
A: The front panel LCD displays real-time speed, setpoint, actuator position, and fault codes. Remote diagnostics via Modbus provide access to 50+ parameters including runtime hours, alarm history, and sensor status.

Q: Does the unit require periodic calibration?
A: No routine calibration is needed. The digital control architecture maintains accuracy over the product lifetime. Annual verification of speed accuracy is recommended for critical applications.
