Application of the Month:

The PN4000 Rail Yard Utility Vehicle is custom built with a 3.331L 4-cylinder Kubota V3307 engine, equipped with a GAC ALR190-KV07-12 actuator positioning the fuel control rack and an EEG6500 digital governor. The vehicle uses a hydrostatic drive and four-wheel steering that enables it to maneuver within a five-foot turning circle. The digital governor provides two fixed speeds, a 1000 RPM idle, and 2000 RPM “work speed setting” when drive mode is detected, or when the unit is switched to compressor mode.

Tip of the Month:

What are the LEAD CIRCUIT and SOFT COUPLING options, offered in the ESD5131 and ESD5500E series governors, and what do they do?

The LEAD CIRCUIT enables the governor to be more responsive and typically increases the range of the GAIN adjustment to increase overall performance of slower engines. This feature is controlled with switch C1 and is normally “ON” which eliminates slow or moderate hunting at higher GAIN settings. Move the switch to the “OFF” position if there is a fast instability in the system.

The SOFT COUPLING, switch C2, controls a circuit designed to eliminate fast erratic governor behavior caused by a very soft or worn couplings in the drivetrain between the engine and generator. It works by averaging out any instantaneous RPM variations to create a stable speed reference for the PID governor routine. The soft coupling switch C2 is normally “OFF”. Move it to the “ON” position if fast erratic engine behavior, due to a soft coupling is experienced.
