ECON-4, SW version 1.4 rev.1, ©ComAp – March 2016 Draft 19
ECON-4 Reference guide.pdf
CB request set to 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.
Speed control handling (Speed request modes)
Speed request set to 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).
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 ANA mode
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 %
