ECON-4 1.4.0 Global Guide
24
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 Speed request 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 firmware without support of ECON4 or even for collaboration with thirt party controller or 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 speed running (Idle and Nominal speed adjustment 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 (Speed UP and Speed Down) to control the speed or load (in case of parallel with mains
operation).

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 the DATA mode,
adjust the IGS-NT inputs/outputs in the following way:
