In this article, we mainly talk about CCEC Cummins diesel engine 4914090/4914091 control governor.

1. Introduction

The 4914090/4914091 governor is a high performance diesel engine speed governor which was developed based on environmental protection concept.


As our previous generation products, it includes wide-supply-voltage adaptability, anti -interference ability, and protection ability for a variety of abnormal condition.


It could reduce the emission and smoke during engine start.

It is a diesel engine protection controller which is stable, reliable and safe.

2.1.2 Run/Idel mode

2.1.3 Provide external speed trimming port, which can realize external manual adjustment of speed or adjust with automatic controller.

2.1.4 Run speed and idle speed setting

2.1.5 Gain and Droop setting,

2.1.6 Smoothly rising control setting.

2.2 Working parameters

2.2.1 Rated Voltage: 24V DC

2.2.2 Maximum Output Current: 2.1A

2.2.3 Speed Signal: Sinusoidal Signal, effective value not less than 1.7V

3. Operating Instructions

3.1 Appearance and Installation Dimension:

3.2 Connection mode

3.2.1 Battery:

1# TerminalPower+;2# TerminalGND

Use 1mm2 or larger copper wire.

3.2.2 Actuator:

3# & 4# Terminals: Actuator

Use 1mm2 or larger copper wire.

Do not short circuit the terminals to GND.

3.2.3 Speed Signal

5# Terminals: Speed Signal6# Terminals: GND for Speed Signal

Make sure the Common Ground Terminals are unified, when the speed signal source is common used by more than one equipment.


3.2.4 Remote Speed Adjust:

A potentiometer installed on the panel would be connected to 7#, 8# and 9# terminals as a Remote Speed Adjuster.

The 47K- Ohm Potentiometer’s PN is 3035105. 2# pin should be connect to the 8# terminal of Control Governor. A 200K-Ohm resistor could be series connection in the wire in order to improve engine stability, if necessary.

Keep the 8# and 9# terminals open if Remote Adjusting is not needed.


3.2.5 Idel/Run Mode Switch:

10 # terminal is Idle / Run mode switch interface. A switch or relay could be connected between 7# and 10 # terminals.

When the switch or relay is open, control governor will work in RUN Mode. When the switch or relay is connected, control governor will work in IDLE Mode.


3.2.6 Common GND

11 # terminal is spare GND, and do not need to be connected. Do not attach the battery negative to 11 # terminal, the control governor may be damaged.

A# and B# terminals are damping, it was needed when the oscillation of the coupling between engine and generator occurred, and do not need to be connected in general condition.

3.3 Debugging and Use:

3.3.1 Droop

This Potentiometer is used to set the speed decline percent when the engine is loaded.

Droop Potentiometer is used with Gain Potentiometer in order to keep the engine work stability.

3.3.2 GAIN

This Potentiometer is used to set the sensitivity of speed adjustment when the engine’s load is changed.

Gain Potentiometer is used with Droop Potentiometer in order to keep the engine work stability.

3.3.3 RUN

This Potentiometer is used to set the target Run-Speed.

3.3.4 IDLE

This Potentiometer is used to set the target Idle-Speed.


3.3.5 SMOOTHLY RISING CONTROL

This setting time is used to set the sensitivity of Smoke Control.

The larger potentiometer set, the more smoke control. But too large setting time may cause difficult engine start.

The potentiometer is usually arranged on the 10s point.
