2 System overview

2.1 Description of the governor system

ECON-4 is a flexible speed governor capable to operate in various configurations. Possible configurations can be:

a. Control via CAN – it reads the values of control bits and required analog values from the CAN bus line and

not from its terminals (expect from BIN S4.6 Run/Stop, this signal must be present in all 3 modes)

b. Control via Binary signals

c. Control via Analogue and binary inputs.

Speed and power of a single fuel engine is always controlled by the actuator connected to ACT terminals or Analog Output in case of actuator with 0-20mA(4-20mA) usage. This actuator can control a fuel rack for diesel engines or a mixture throttle valve for gas engines.

ECON-4 ADV is advanced version, it is dedicated specially to control of engine in island operations where load steps are expected.

2.1.1 Control by CAN-bus

ECON-4 can receive values of somebinary and analog control inputs via CAN-bus communication line from engine controller, (see setpoints Speed request (page 49) or CB request (page 50) for more information). This arrangement can significantly simplify the wiring on site.

Control of speed request by CAN-bus is active only if setpoint Speed request (page 49) has value DATA

Control of GCB and MCB feedback by CAN-bus is active only if setpoint CB request (page 50) has value DATA.

4.4.1 General

Use grounding terminals.

The “-“terminal of the battery has to be properly grounded.

Cables for binary inputs and analogue inputs must not be placed along power cables.

Analogueinputs should use shielded cables, especially when length >3m.

Always use shielded cable for Magnetic pick-up.

ECON-4 1.4.0 GlobalGuide

4.4.2 Grounding

Use as short as possible cable to thegrounding point on the switchboard.

Use cable min. 2,5 mm2.

The “-“terminal of the battery has to be properly grounded.

4.4.3 Power Supply

Use min. power supply cable of 4mm2.

Maximum continuous DC Power supplyvoltageis 36 V DC. Maximum short term allowable power supply voltage is 39 V DC. The ECON-4’s power supply terminals are protected against large pulse power disturbances. When there is a potential risk of the controller being subjected to conditions outside its capabilities, an outside protection device should be used.

Power Supply Fusing

An eight-amp fuse should be connected in-line with the battery positive terminal to the controller andmodules. ECON-4 should never be connected directly to the starting battery.

Recommended fuse is slow type– T8A.

4.4.4 Binary inputs

Binary inputs have internal load resistor 4.4 kΩ connected to the battery plus.

Image 4.2 Binary inputs wiring scheme

ECON-4 1.4.0 GlobalGuide

Binary inputs are used to control the function of the ECON-4 digital governor.

Binary inputs can be read from:

the physical Binary inputs (terminals S4.x),

from the CAN-bus (byte Command in the Receive PDO),

in dependence on the value of thesetpoint Speed request.

NOMINAL (S4.3)

The Required speed is set to Nominal RPM if the Nominal input is closed, otherwise is the Request set to Idle RPM.

SPEED UP (S4.4)

Inputs SPEED UP and SPEED DOWN are used for setting of the speed reference of the engine. The speed reference can be changed in the range from Nominal RPM - PerChSpdNom% to Nominal RPM + PerChSpdNom%. Setpoint: EngineRPM:PerChSpdNom [1-20%] defines the maximum Percentage change of Speed from Nominal in case BIN or ANA mode of control is used.

Setpoint BI Speed ramp decides how fast the speed reference changes, if the inputs SPEED UP or SPEED DOWN are active.

Note: Inputs SPEED UP and SPEED DOWN are active only if the setpoint Speed request has value BIN.

SPEED DOWN (S4.5)

Setpoint BI Speed ramp decides how fast the speed reference changes, if the inputs SPEED UP or SPEED DOWN are active.

Note: Inputs SPEED UP and SPEED DOWN are active only if the setpoint Speed request has value BIN.

RUN (S4.6)

If the input is not active, governor immediately set the actuator to stop position.

DROOP (S4.7)

The input activates droop function – see setpoint Droop (page 62).

BIN 8 (S4.8)

BIN 8 is reserved for next functions.

4.4.5 Analog inputs

There are 2 analog inputs available on the ECON-4. Each of them can be configured either as 0-20mA or 0-10V range by jumper setting – seein table below. The analoginput function is fixed.

SPEED REQUEST (S3.1)

The input defines speedreference. It can be set in the range from Nominal RPM - PerChSpdNom% to Nominal RPM + PerChSpdNom%. Setpoint: EngineRPM:PerChSpdNom [1-20%] defines the maximum Percentage change of Speed from Nominal in case BIN or ANA mode of control is used.

Example: Analog input SPEED REQUEST is set to range 0 – 10 V, Nominal RPM is 1500 RPM, Input voltage is 6 V. Speed reference is then ReqSpeed = 1500 + (PerChSpdNom/100)*1500*(6-5)/5 = 1524 RPM. PerChSpdNom = 8 in the previous calculation.

Note: Input SPEED REQUEST is active only if the setpoint Speed request has value ANA.

ACTIVE POWER (S3.2)

Input from the external transmitter of Active power. Value of the Active power is used to improve load step response of the governor. Input ACTIVE POWER is active only, if the setpoint Speed request has not value DATA. The input sensitivity can be adjusted by setpoint Load anticip.

Note: Input ACTIVE POWER is active only if the setpoint Speed request has value BIN or ANA and setpoint

Load anticip > 0.

Collaboration with ECON-4Slave

Physical analog input on terminal S3.2 canbe used also when ECON4-Slave is used. In this case feedback from slave actuator is put on analogue output on slave and can be connected back to masterto see it in one Winscope (connected to master) and in controller thru CAN as Misf Angle.

Original Misf Angle calculation is not used in latest version of ECON4 and in version 1.4 is used to show feedback from Slave. If feedback from slave is connected to analog input on S3.2 setpoint LoadAnticipationhas to be =0. Othervise wrong value will be used forload anticip resulting unstability and unpredictive control

Principle of connection Master Slave is shown on next picture.

ECON-4 1.4.0 GlobalGuide

4.4.6 Analog output

ECON-4 has one analogoutput configurable to 0-10V or 0-20mA range by jumper setting – see in table below. If configuredto 0-20mA range, output works as an active current source. The analogoutput function is fix (copy of the value sent to ACT output - GAS DOSE). Analogueoutput range is fully programmable in range 0-10V or 020mA – see setpoints: Analog settings: AOUT 0%and AOUT 100%.

E.g an actuator with input 4-20mA is used, theAOUT2 range setpoints should be adjusted in the following way:

ECON-4 1.4.0 GlobalGuide

Analog sensors: AOUT2 0% = 20% (20% from 20mA = 4mA)

Analog sensors: AOUT2 100% = 100%

andjumper P6 adjusted to current option.

In case an actuator with an input 0-5V is used, the AOUT2 setpoints should be adjusted in the following way:

Analog sensors: AOUT2 0% = 0%

Analog sensors: AOUT2 100% = 50%

andjumper P6 adjusted to voltage option.

4.4.7 Interface to actuators

ECON-4 has one interface to actuator. The interface has a bipolar PWM output in bridge configuration and position feedback input.

It is recommended to connect PWM output by a twisted cable and connect feedback input by a shielded cable.

P21

P21 10V

It is electro-hydraulic actuator – in principle a small electromagnetic actuator with hydraulic booster. It has proportional characteristic – the bigger is the current, thebigger is the angle of the actuator, the polarity of the current is not important. Actuatoris usually without electrical position feedback. For this actuator choose option ActType: Wiring: LINEAR NO FEEDBACK

ECON-4 1.4.0 GlobalGuide

With current input max. 10A

Example: Typical examples are actuators from GAC, Woodward Flowtech ITB.

It is electro-magnetic actuator with a strong return spring. This is in principle electromagnet with proportional characteristic – the bigger is the current to the actuator, the bigger is the angle of the actuator. The polarity of the current is not important. This type of actuator can be with or without position feedback. For this actuator choose option ActType: Wiring: LINEAR or LINEAR NO FEEDBACK.

Motor driven actuators

Example: Typical examples are actuators from Heinzmann (STG 6, 10, 30, 2040.)

It is in principle a DC electromotor driving actuator lever. Since it is a motor, it has integrating characteristic – as longas the current flows through the actuator, actuator’s lever moves. Direction of movement of the actuator lever depends on polarity of the current. This typeof actuator has always position feedback. For this actuator choose option ActTypex: Wiring: BRIDGE. For Heinzmann actuators, Jumper P21 – supply of the position feedback must be set to option 0-10V. For Woodward and GAC actuators this jumper must be set to position 05V.

ECON-4 1.4.0 GlobalGuide

4.4.8 Speed Pick-up

Always use a shieldedcable, connect shieldingto a grounding screw. ECON-4 supports both active (powered) andpassive (magnetic) pickups.

Pick-up Recommended wiring Jumpers

Active NPN

Active PNP Link 1 and 2

Passive Link 2 and 3

If the jumper is in position 2-3, terminals GND and SIG areseparated from all other terminals. This enables to share one pick-up by two modules, for instance by a speed governor and by an ignition, without danger of creating a ground loop.

Link 1 and 2 Link 4 and 5

4.4.9 Communication wiring

CAN bus connection

ECON-4 is equipped by CAN communication line. CAN bus terminals are electrically isolated from any other terminals.

Note: Following ECON-4 CAN setting is necessary to communicate with InteliSys NT:

CAN mode (Object number 10338) = 1 sets ComAp protocol

CAN NODE-ID (Object number10306) = 88 (decimal) sets address of the module

ECON-4 1.4.0 GlobalGuide

Connection rules

CAN bus line must be connected in series, from one unit to the next (no star, no cable stubs, and no branches) both ends must be by the 120-ohm (internal or external) resistorterminated. Maximal CAN bus length is 200 meters.

ECON-4 contains internal 120-ohm resistor, connected through a removable jumper P7.

For CAN data cables details seechapter Technical data – Communication interface. CAN cable shielding connect to CAN COM terminal.

5.1 Quick start - how to set ECON4 and controller

The following description should help you to quick adjust the ECON-4speed governor. The ECON-4 can be found in different modes used for control of moduleand engine.

Basically any input signal of ECON4 can be suppliedeither using wired signal or using data from CAN1 line.

Input signals of ECON4 areseparated in to two groups each group can be controlled in different way.

Group Setpoint Signal

Breaker`s feedback

Speed control

5.1.1 Breakers feedback handling (CB request modes)

CB request set to BIN mode

Image 5.1 CB request - BIN mode

ECON-4 1.4.0 GlobalGuide

In case of binary control of breaker`s feedback, signals from breakers has to be wired to terminals S4.1 and S4.2. You do not needto link any source to Binary outputs of ECON4 in Genconfig.

CB request set to DATA mode

Image 5.2 CB request - DATA mode

In case of DATA control of breaker`s feedback, logical signals from breakers has to be linked to Binary outputs of ECON4 in Genconfig. Terminals S4.1 and S4.2. do not need to be wired.

5.1.2 Speed control handling (Speed request modes)

Speed request set to ANA mode

Image 5.3 Speed request - ANA mode

ECON-4 1.4.0 GlobalGuide

In case of ANAlogue mode, the required speed is controlled via Analogue input S3.1 (voltage or current signal, connected between terminals S3.1 and S3.3). The binary control signals (Idle/Nominal, Run/Stop, Droop) are evaluated from the binary terminals S4.3 – S4.8 as in case of BINary mode.

In case the source of the Analogue input Speedrequest to ECON-4 is ComAp controller (e.g. InteliSysNT), adjust the ComAp setpoints in the following way:

Sync/Load ctrl: SpeedGov Bias = 5 Volts (for 1500 RPM sets)

Sync/Load ctrl: SpeedGovLoLim = 0 Volts

Sync/Load ctrl: SpeedGovHiLim = 10 Volts

Sync/Load ctrl: Freq gain = 5 %

Sync/Load ctrl: Freq int = 5 %

Sync/Load ctrl: Angle gain= 10 %

You do not need to link any source to Binary outputs of ECON4 in Genconfig. This type of control can be used with firmwarewithout support of ECON4 or even for collaboration with thirt party controlleror without any controller just as standalone speed controller (no Data communication to ECON4 is needed).

Necessary signal – RPM signal – connected to RPM1 terminal – S7.2 and S7.1

Speed request set to BIN mode

Image 5.4 Speed request - BIN mode

In case of BINary control, the ECON-4 is fully controlled via binary inputs – terminals S4.3 – S4.8.(except CB control). The input S4.6 is the ON/OFF signal to ECON-4, in case it is not active, speed governor will not open the throttle. In case it is deactivated during engine running, throttle is immediately closed. Use BIN S4.3 to switch from Idle running to Nominal speedrunning (Idle and Nominal speedadjustment is in ECON-4 setpoints: Engine RPM). Do not put the Idle RPM and Nominal RPM to the same value. In case you want engine to be running at Nominal RPM without Idle period, leave BIN S4.3 activated all the time.

Use BIN S4.4 and S4.5 (SpeedUP and Speed Down) to control the speed or load (in case of parallel with mains operation).

Necessary signal – RPM signal – connected to RPM1 terminal – S7.2 and S7.1

Speed request set to DATA mode

In case of DATA control almost all the data can be sent from ComAp IGS-NT controllers to ECON-4 via CAN1 line. The only binary input RUN/STOP – S4.6 must be activated physically as well. To use theDATA mode, adjust the IGS-NT inputs/outputs in thefollowing way:

ECON-4 1.4.0 GlobalGuide

a. Configurationof ECON-4 module

Go to GenConfig, card Modules – Extension modules – Others – ECON-4 > Insert

b. Configurationof Binary outputs of IGS-NT

All the ECON-4inputs are in fact IGS-NT outputs (IGS-NT controller sends the signals to ECON-4 unit). BO1 – this configuration of feedback is independent andis described in previous chapter Breaker`s feedback handling (CB request modes) BO2 – this configuration of feedback is independent andis described in previous chapter Breaker`s feedback handling (CB request modes) BO3– Idle/Nominal – configure on this output signal which defines switching from Idle operation to Nominal ROM run. The Logbout signal: Idle/Nominal of IGS-NT canbe used. In case the Idle period is required to be skipped, configure on this output signal Log bout: Logical 1. BO4 – Run Stop – together with binary input S4.6 RUN/STOP this signal must be activated to unblock ECON-4 function. Signal Log Bout: Fuel solenoid can be used. BO5 – Droop – use the Droop function in case of in Mains parallel operation to make the load control function more stable (protectagainst power swing). Use signal e.g. GCB feedback.

ECON-4 1.4.0 GlobalGuide

BO1 and2 setting is separated and described in previous chapter

c. Configuration of Analogue inputs from IGS-NTto ECON-4 (those are signals from ECON4 to controller, in

ourconfiguration it is namedfrom controllers point of view, so inputs) AIN1 – Engine RPM

The engine RPM can be sent from ECON-4 into the IS-NT via CAN line as well. Configure the AIN1 in the following way:

Function – RPM pick-up

Sensor– Electronic

the IGS-NT controller.

d. Configurationof Analogue outputs from IGS-NT to ECON-4

AOUT1 – Active Power Rel ECON-4 is equipped with the Load anticipationfunction to react as quickly as possible to the sudden changes of the engine power. For this function ECON-4 needs information about power and in case of DATA mode this can be sent to ECON-4 via CAN. Adjust theAOUT1 in the following way: Source: Genervalues: ActPwr rel Normalize: YES Resolution: 0,1

AOUT2 – Speed RequestThe Speed request in case of DATA mode is sent via CAN line. Configure the output AOUT2 in the following way: Source: Sync.

ECON-4 1.4.0 GlobalGuide

Load ctrl: SpeedReqRPM

IMPORTANT: Configuration of Analog output AOUT2from IS2GASXX to ECON-4 has to be

configured as SpeedReqRPMx8

Controller setting in case ECON4 is set to communicate with controller via CAN1 (Speed request set to DATA mode)

Besides the above mentioned inputs/outputs adjustment, the IGS-NT setpoints shall be adjusted in the following way:

Sync/Load ctrl: SpeedGov Bias = 0 Volts

Sync/Load ctrl: SpeedGovLoLim = -10 Volts

Sync/Load ctrl: SpeedGovHiLim = 10 Volts

Sync/Load ctrl: Freq gain = 5 %

Sync/Load ctrl: Freq int = 5 %

Sync/Load ctrl: Angle gain= 10 %

IMPORTANT: Please, take in account, there are several setpoints of ECON-4, which are not

accessible via IGS-NT control unit in case of DATA mode. These parameters are crucial for ECON-4

and used Actuator adjustment and so these are accessible via ECON-4 connection ONLY. Use

ComAp PC sw WinScope to adjust these setpoints.

5.3.5 ECON adjustement for various types of actuators

Basically there are available 3 types of actuator types:

LINEAR – actuator is driven by a current, which acts against a spring which pushes the actuator to close

position. Actuator is equipped with position feedback signal. Available feedback signal for ECON is 0,4 to 4,6 Volts DC.

Misfiring evaluation from ECON-4 is not implemented in version 1.0

ECON-4 1.4.0 GlobalGuide

LINEAR NO FDB – actuator is driven by a current, which acts against a spring which pushes the actuator

to close position. Actuatoris not equipped with position feedback signal.

BRIDGE – in principal electromotor, one current polarity moves the actuator to one position, reverse polarity

moves the actuator to another position.

Adjustment for LINEAR actuator type (typically Woodward

A. At first check the position feedback level, in case it is not within limits 0.4 to 4,6 Volts, then use the LINEAR

NO FDB adjustment.

B. Connect to ECON-4 via USB connector, using PC program WinScope.

C. Adjust the Position feedback limits in parameter group: AnalogSensors: Fdb 0 pos to voltage of feedback in

case the actuator is fully closed, and Fdb 100 pos to value of voltage when actuator is fully opened.

D. ECON-4 does not measure the current through actuator. The output signal is PWM, with adjustable

frequency. The maximum ECON-4 current is given by resistance of the actuator and power supply of ECON-4. ECON-4 is rated to maximum 8 Amps. In case the actuator has resistance 32 Ohms and power supply is 24V, then maximum ECON-4 current is: 24/32 = 0,75A = 750mA. This means 100% of ECON current is 750mA. In case the maximum allowable actuator current is 250mA, then this is 33.3% of maximum ECON-4 current. This value will be used for the maximum current limitation.

E. Choose one ActType x group, e.g. ActType 1 and adjust parameter Wiring to LINEAR, and adjust

parameters Act gain to 10%, Act int to 10% and Act der to 10%

F. Parameters: ActTypex (In this case ActType 1): ActCur 0% and ActCur 100% are not used, so their value is

not important

G. Parameters: ActTypex (In this case ActType 1): Act MaxCur is maximum allowable current, in case bigger

current is detected (in fact bigger output PWM signal is detected)for longer then: ActMaxCurDel, then the output is limited to value ActReduced Cur. So in case we have actuator with resistance 32Ohms, ECON powersupply is 24Volts and maximum allowable actuator is 250mA, then it is recommendedto adjust: Act MaxCur = 33,3%, (24V / 32Ω = 750mA, 250mA is 33,3% from 750mA), Act MaxCurDel = 5 sec, Act ReducedCur = 10%.

H. Adjust parameter: Main PID: ActuatorType to the actuator which youuse, so in this case ActType 1.

I. Connect the actuator to ECON-4, outputs ACT+ ACT- (take care about polarity)

J. Adjust ECON-4 parameter: Main PID: ECON-4 mode to MANUAL and run WinScope recording with values:

Gas Dose and Act1 Fdbck in range 0.0 – 100.0%.

K. When recording is active, change parameter: Main PID: Act position from 0 to 10, 20, 30, .. 100 and check

the response of the actuator (via feedback signal in WinScope). In case theresponse is too lazy or too fast, then update thecorresponding Act gain, Act int and Act der parameters in ActTypex (in ourcase ActType1) to get required response.

L. After adjustment is finished, put parameter: Main PID: ECON-4 mode to AUTOMATIC

M. Based on the chosen type of control (BIN, ANA, DATA) connect the required signal

N. Adjust all other parameters like Nominal, Idle speed, Geer teeth, Overspeed, Speed and Load PID, (to the

number which ECON-4 output you areusing)

O. ECON-4 is ready forstart attempt.

Adjustment for LINEAR NO FDB actuator type (typically GAC, Woodward)

A. Connect to ECON-4 via USB connector, using PC program WinScope.

B. Choose one ActType x group, e.g. ActType 1 and adjust parameter Wiring to LINEAR NO FDB

ECON-4 1.4.0 GlobalGuide

C. ECON-4 does not measure the current through actuator. The output signal is PWM, with frequency 6000 Hz.

The maximum ECON-4current is given by resistance of the actuator and power supply of ECON-4. ECON4 is ratedto maximum 8 Amps. In case the actuator has resistance 32 Ohms and power supply is 24V, then maximum ECON-4 current is: 24/32 = 0,75A = 750mA. This means 100% of ECON current is 750mA. In case the maximum allowable actuator current is 250mA, then this is 33.3% of maximum ECON-4current. Adjust Act Cur0% to 0% and Act Cur 100% to 34% (250mA from 750mA). By this the output is scaled from 0 to 250 mA.

D. Parameters: ActTypex (In this case ActType 1): Act MaxCur is maximum allowable current, in case bigger

current is detected (in fact bigger output PWM signal is detected)for longer then: ActMaxCurDel, then the output is limited to value ActReduced Cur. The Act Max Curr is calculated from the value Act Cur 100%, so it means, that the current limitation is in this case already done by adjustment of ActCur 100%, and Act Max Cur shall be adjusted to 100%. Act MaxCurDel and ActReducedCur then can be adjusted to any value.

E. Parameters: ActTypex ()ActType 1 in this case) Act gain, Act int, Act der has no meaning for the LINEAR

NO FDB adjustment.

F. Adjust parameter: Main PID: Actuator Type to theactuator which you use, so in this case ActType 1.

G. Connect the actuator to ECON-4, outputs ACT+ ACT- (take care about polarity)

H. Adjust ECON-4 parameter: Main PID: ECON-4 mode to MANUAL andrun WinScope recordingwith values:

Gas Dose and Act1 Fdbck in range 0.0 – 100.0%.

I. After adjustment is finished, put parameter: Main PID: ECON-4 mode to AUTOMATIC

J. Based on the chosen type of control (BIN, ANA, DATA) connect the requiredsignal

K. Adjust all other parameters like Nominal, Idle speed, Geer teeth, Overspeed, Speedand Load PID,

ActChannel (to the number which ECON-4 output you areusing)

L. ECON-4 is ready for start attempt.

Adjustment for BRIDGE actuator type (typically Heinzmann)

A. At first check the position feedback level, in case it is not within limits 0.4 to 4.6 Volts, then the bridge

actuator cannot be controlledwith ECON.

B. Connect to ECON-4 via USB connector, using PC program WinScope.

C. Adjust the Position feedback limits in: AnalogSensors: Fdb 0 pos to voltageof feedback in case the actuator

is fully closed, and Fdb 100pos to value of voltage when actuator is fully opened.

D. Choose one ActType x group, e.g. ActType1

E. ECON-4does not measure the current through actuator. The output signal is PWM, with frequency 6000Hz.

The maximum ECON-4current is given by resistance of the actuator and power supply of ECON-4. ECON4 is ratedto maximum 8 Amps. In case the actuator has resistance 2,5 Ohms and power supply is 24V, then maximum ECON-4 current is: 24/2.5 = 9,6A but ECON max allowable current is 8 Amps!! So the output must be limited. This means 100% of ECON theoretical current is 9,6A. In case the maximum allowable actuator current is 5A, then this is 52% of maximum ECON-4 theoretical current. This value will be used for the maximum current limitation. So adjust ActType1: Act Max Cur = 52%, Act Max Cur Del = 5 sec and Act ReducedCur = e.g. 20%. In case bigger current is detected (in fact bigger output PWM signal is detected) forlonger then: ActMaxCurDel, then the output is limited to value ActReduced Cur.

F. Adjust parameter Wiring to BRIDGE, and adjust parameters Act gain to 10%, Act int to 10% and Act der to

10%

ECON-4 1.4.0 GlobalGuide

G. Parameters: ActTypex (In this case ActType 1): ActCur 0% and ActCur 100% are not used, so their value is

5.6 Detailed fucntion

5.6.1 Block schematics - speed governor

Overspeed protection in ECON4-ADV

Instead of value in the middle between Nominal and Overspeed thereis additional RPM level defined in setpoint Engine RPM: PreOverSpeed in ECON4-ADV versions. When RPM reaches this level, Gas Dose Value (throttle position) goes to value in setpoint Engine RPM: PreOverSpReduct – can be set to Idle Fuel or Close.

This feature was added to prevent overspeedwhen Load is removed – typically switch off large load in island operation.

Overspeed protection

In case the actual RPM crosses RPM value: Engine RPM: Overspeed, then the Gas Dose is immediately forced to the zero – throttle is closed and shutdown is issued.

There is proactive action taken to try to keep engine running without shutdown, when actual RPM reaches value in the middle between Nominal and Overspeed value. In this case, when RPM crosses this middle value, Gas Dose is set to Idle position and when RPM drops back below this middlevalue, speed PID will continue to regulate RPM.

Purpose of this behavior is to prevent the Overspeed situation by detecting the RPM increase and step change of the fuel (closing the fuel). As the RPM are dropping down subsequently towards the Nominal RPM the fuel is

ECON-4 1.4.0 GlobalGuide

changed again to maintain the RPM on Nominal value andnot to cause a dip in the RPM.

Speed governor function in Idle or local load mode

ECON-4 compares the Reference and Actual speeds of the engine and calculates theRegulation error.

The Actual speed is measured from the period of the signal generated by the magnetic pickup sensing gears of the flywheel.

Speed reference canbe generated by 3 ways:

by Binary inputs,

by Analogue input

from CAN bus,

For more information see setpointSpeed request (page 49). The Regulation error is then processed by the standard PID control structure with proportional, integration and

derivative parts. The PID setpoints – Gain, Int andDer define the quality of regulation.

The parameters of the PID control structure are different if the engine is in:

no-load operation,

loaded operation

For more information see setpoint .Description (page 53) The output of the PID control structure is then added together with the Load anticipation feedback, which is

directly proportional to the engine power. The output from the last sum is limited by the Anti-windup Limiter module, which reduces the integrator’s output signal so that the sum of the signals from the Gain, Integrator, Differentiator and Loadanticipation blocks equals exactly the limit MaxFuel.

Speed governor function in parallel mode

When engineis in parallel to Mains, Econ4 works just as amplifierand converts Speed request signal to Gas Dose signal according Speed/Fuel line as follows

ECON-4 1.4.0 GlobalGuide

Transition to parallel from zero local load.

When engineis running without load, speed request from controller is in bias position and enginehas a throttle in Idle position. So if those values are properly set in to ECON4 setpoints while going to parallel, engine startso to runin SGO Bias and IdleFuel point on Speed/Fuel line. When request for load is increased in controller, Speed request is increased andthrottle is opened and vice versa.

Transition to parallel from non-zero local load.

There could be situation in SPtm for example, when just GCB is closed and generator supply a local load. So MCB is opened and GCB is closed and PID with Load parameters is used to control speedand Throttle position. It is clear than Throttle is not in Idle position but on higher position. Now after synchronization, MCB is closed, throttle stays in the same position because no Higher Power is generated just after synchronization and Actual speed request is in Bias position because no power control has been done in previous stage. So there is difference betweenactual speed request andspeed request corresponding to actual throttle position. This difference is called Speed request offset and we keep it to make transition burpless. When controller increase aped request to provide more powerto Mains, we move throttle to higher position on the Speed/fuel line andit works fine. But we cannot keep speed request offset all time, because when controller decrease speed request throttle would go to zero position and even to negative value (theoretically). So we keep Speed request offset just for one minute from breaker closing and then starts to decrease this offset. This will move throttle down, but controller will notify decreasing of power and increase speed request. After a while, using this mechanism Speed request offset oi zero and actual throttle position respects speedrequest and Speed/fuel line.

Speed request offset is decreased according ramp, which is set in setpoint SGOoffsetRamp. Time in this setpoint is time needed to change Speed request offset from 10V to 0V.

8.1 Setpoints

What setpoints are:Setpoints are analog, binary or special data objects which are used for adjusting the controller to the specific environment. Setpoints are organized into groups according to their meaning. Setpoints can be adjusted from the controller front panel, PC, MODBUS, etc. All setpoints canbe protected by a password against unauthorized changes. Password protection can be assigned to thesetpoints during the configurationprocedure.

See the chapter Entering password (page 28)forthe instructions how to enter and modify a password.

IMPORTANT: Setpoints are organized in logical groups for better orientation. Use WinScope or

InteliMonitor software to modify the setpoints. For details see chapter ECON-4 configuration and

PC tools (page 32)

ECON-4 must be in AUTO for normal operation. ModeMAN can be used during installation to check the function of the actuator and linkage. If ECON-4 is in MAN mode, it sets the actuator to position Act position. It can be switched to MAN mode only any time even engine is running. This allows measurement of transition curve to calculate PID parameters.

Note: ECON-4 when engine is running set the same value to setpoint Act position as position where throttle is.

It assure bump less transition.

IMPORTANT: Even Overspeed protection is active in all modes, be carefull when setting throttle

position manualy. Engine can accelerate when breaker opens or when throttle position is too

LINEAR : It is electro-magnetic actuator with a strong return spring. This is in principle electromagnet

with proportional characteristic – thebigger is the current to the actuator, the bigger is the angle of the actuator. Direction of movement of the actuator lever does not dependon polarity of the current. This type of actuatorhas position feedback. Typically it is GAC actuators or Woodward 0-200mA, or PWM.

BRIDGE : typical examples are actuators from Heinzmann.

It is in principle a DC electromotor driving actuator lever. Since it is a motor, it has bipolar integrating characteristic – as long as the current flows through the actuator, actuator’s lever moves. Direction of movement of the actuator lever depends on polarity of the current – when the polarity of the current is reversed, direction of movement of the actuator lever reverses as well. This type of actuator has always position feedback. Choose this possibility for Heinzmannactuators and connect the position feedback signal

LINEAR NO FDB : For example it is electro-hydraulic actuator – in principle a small electromagnetic

actuator with hydraulic booster. It has unipolarproportional characteristic – the bigger is the current, the bigger is theangle of the actuator. Direction of movement of the actuator lever does not dependon polarity of the current. Actuator is without position feedback.

There are 4 identical groups of setpoints in ECON-4. They are used to setupthe output circuits for particular types of actuators andtune the actuator position PID loop.

Note: Normally these Actuator type setpoints are predefined from the factory and there is no need to readjust

them. Modify them if you have a non-standard, or non listed actuator only – see List of tested actuators by
