2 General

2.1 Introduction

The InGovern Series electronic engine speed governor consist of models suitable for both diesel and gas

engines. Its digital processing capability not only provides flexibility in configuration but also allows CAN

J1939 data exchange with many modern controllers. The unit will internally convert the signal from a

standard inductive flywheel pick-up to an RPM value, display it on the 4-digit LED display and send it as a

standard J1939 value to a connected controller.

The unit’s desired speed can also be set by standard J1939 SpeedUp/SpeedDown commands over the

CAN Bus connection as well as by a conventional 0-10V synchronizing and load sharing signal input. This

J1939 integration simplifies the wiring thus saving installation time and also allows implementation of more

sophisticated controller features.

InGovern smart speed controllers are fully potted for sealing and vibration resistance and suitable for

mounting on or close to a running engine. They provide precise (<0.25%) isochronous rotational speed

control.

The unit is supplied pre-configured and once the number of flywheel teeth is input (1 x press of [Fn] button

then [+] or [-] until the correct value is displayed) then the engine will run. All parameters are stored in non-

volatile memory.

Fine tuning of the main PID loop and other common features can be done using the same 3 buttons on the

front panel. The supplied PC software (which connects via a standard USB cable – no dongle required)

provides an overview of all settings, allows user-friendly PID adjustment on a running engine and allows

access to secondary parameters including a second PID loop. The final configuration can be saved and

downloaded to other similar units for multiple engine applications or for series production.

2.2 Safety instructions and Warnings

Before installing and starting the device, please read the operating instructions. These contain important

notes for safety and use.

No liability can be accepted for damage arising from failure to follow the instructions or any inappropriate

use.

The governor may only be used for the manner of operation prescribed in the operating instructions and

only in connection with third-party devices and components recommended or installed by us or software

supplied by us. Any other use shall be considered inappropriate use and will result in the voiding of all liabil-

ity and warranty claims against the manufacturer.

Interventions and alterations that influence the safety technology and the functionality of the governor may

be carried out only by the manufacturer. Fault-free and safe operation is conditional upon competent

transport, assembly, and installation as well as qualified use and correct maintenance.

All relevant accident prevention regulations and other generally recognised technical safety and health and

safety at work rules are to be observed. Fault-free functioning of the machinery and its peripheral compo-

nents is only guaranteed with original accessory parts and spare parts.

The InGovern engine speed governor is robust enough to be placed in a control cabinet with other operat-

ing control devices or installed on the motor. If water, mist, or condensation can come into contact with the

controller, it should be mounted vertically, allowing the liquid to flow away from the controller. Extremes of

heat should be avoided.

2.2.1 Overspeed protection

IMPORTANT

An overspeed shut down mechanism must be installed separately from

the control system as a safety measure, to prevent motor faults that

may result in damage or injury to machinery or persons.

A secondary shut down device (fuel valve) must be installed.

2.2.2 Safety protection

IMPORTANT

 Protective Earth (PE) must be connected with Battery Minus

terminal always.

2.3 Guarantee terms and conditions

2.3.1 Correct use

The device is intended for exclusive use under the conditions described in the "Technical Data" rubric. Oth-

er uses are potentially dangerous. Huegli-Tech AG cannot accept liability for damage which results from

incorrect use or application other than that for which it was intended.

2.3.2 Use of Accessories

Accessory parts may be installed or added only when they have been explicitly authorised by Huegli Tech

AG. Any claims under guarantee, warranty or product liability shall be void if other parts are used.

The general guaranteed terms and conditions of Huegli Tech AG shall apply.

3.2 General information

The magnetic RPM sensor cable should be shielded to guarantee that no electromagnetic interference can

reach the engine speed governor. The shield should be on-sided on the battery negative.

To maintain the correct distance between the flywheel and the magnetic RPM sensor, the sensor must be

rotated in until the flywheel clicks and then rotated out again for ¾ of a rotation. This achieves the correct

spacing between flywheel and sensor. To be able to start the motor, the sensor must generate at least 1V

AC RMS during the start.

IMPORTANT



The pick-up must be mounted so as to sense the teeth of a full

gear. The flywheel ring-gear is suitable.

 Note: any missing teeth will negatively affect the pick-up signal.

For longer cables (>5m) the cable cross-section is to be increased appropriately to keep the voltage drop

low.

 Battery positive (+) input, connection M, should be fused 10 A.

 The governor should be installed such that the housing has connection with the chassis of the con-

trol cabinet.

 The cable of the actuator must be shielded along its entire length.

 The cable of the magnetic engine speed sensor must be shielded along its entire length.

 The cable of the variable RPM speed input can be up to 5m long. For longer cables, a shielded ca-

ble must be used.

 The shielding must always be grounded such that it does not come into contact with the chassis of

the machine. This is to prevent stray signals from entering the governor and causing interference.

The shield must be grounded at one end.

Important: The InGovern Series is equipped with overcurrent protection on the (Terminal J & K) output to

the actuator. Please note that even through overcurrent protection is in place, repeatedly subjecting the

actuator output to overcurrent or short circuit condition can still result in permanent damage to the product.

Overcurrent protection is activated when the digital display shows = = = =.
