APECS® Programmable Governor for   Isochronous Generators with Load Sharing Capability

WARNING

Read this entire manual and all other publications pertaining to the work to be performed before installing, operating, or servicing this equipment. Practice all plant and safety instructions and precautions. Failure to follow instructions can cause personal injury and/or property damage.

The engine, turbine, or other type of prime mover should be equipped with an overspeed shutdown device to protect against runaway or damage to the prime mover with possible personal injury, loss of life, or property damage.

The overspeed shutdown device must be totally independent of the prime mover control system. An overtemperature or overpressure shutdown device may also be needed for safety, as appropriate.

CAUTION

To prevent damage to a control system that uses an alternator or battery-charging device, make sure the charging device is turned off before disconnecting the battery from the system.

Electronic controls contain static-sensitive parts. Observe the following precautions to prevent damage to these parts.

•Discharge body static before handling the control (with power to the control turned off, contact a grounded surface and maintain contact while handling the control). 

• Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards. 

• Do not touch the components or conductors on a printed circuit board with your hands or with conductive devices.

General Information

Introduction

The DPG-2223-001digital governor is used primarily to govern diesel or gas fueled engines of generator sets. This microprocessor based, digital controller performs across a wide speed range and allows adjustment of all governor features through the built-in user interface. Properly tuned, this governor delivers fast engine response to speed or load change while providing precise stable isochronous operation.

Separately programmable Proportional, Integral, and Derivative gains are provided for tailoring governor response to many engine applications. Other adjustments include acceleration and deceleration ramp rates, startup and torque limits, idle speed set and hold time.

This governor can also provide droop speed control with 100 user selectable droop levels. The governor’s internal FAILSAFE reacts instantly to loss of the engine speed signal or loss of remote speed potentiometer signal.

Features include: 

• Automatic calibration of the remote speed potentiometer   

• Isochronous speed control 

• Droop operation: 0 to 10% of set speed with 1/10 percent resolution   

• User friendly / operator adjustable 

• Precision frequency control: 0.25% 

• Superior temperature stability 

• Reverse battery protection 

• Input voltage range: 9-30 Vdc 

• Smoke control on start up 

• Remote setup 

• Serial communication port
