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 some binary and analog control inputs via CAN-bus communication line from
engine controller, (see setpoints
or
for more information). This
arrangement can significantly simplify the wiring on site.
Control of speed request by CAN-bus is active only if setpoint
has value

Control of GCB and MCB feedback by CAN-bus is active only if setpoint
has value
