automatic or manual controller.
ECON comes in various models to cater for varieties of requirements:
• ECON-A-4C
• ECON-A
• ECON-S
• ECON-M
• ECON-A-4C: It is a AMF controller with 4 channel of analog measurement
and can be site configured as ECON-A or ECON-S or ECON-M.

All these models can be ordered with optional features such as RS485
communication,3 Extra digital inputs of Canopy fan current protection. This
manual has to be read along with the controller selected and all the features
may not be available in all the models.
• Display: 128*64 pixel graphial backlit LCD for ease of readout and symbolic
representation.
• Cyclic Timer based Engine Operation. Maximum engine on time as well as
rest time are programmable

• 10.0 Modes of Operation
10.1 AMF Mode (ECON-A & ECON -A-4C)
• 10.1.1 Auto Mode
ECON monitors the Mains supply, if Mains supply varies beyond set limit of
under/over voltage or under/over frequency or voltage unbalance for more
than their individual programmed supervision time, ECON releases the MCB
contactor (to protect the contactor from failure because of low input voltage)
and attempts to starts the generator after the following conditions are meet:
1. If engine start delay is enabled than the engine will wait for the programmed
delay before cranking the engine
2. In case the mains voltage returns to normal before cranking the engine the
engine shall not be cranked.
Heater/Fuel Pump contact are switched on depending upon their settings.
Heater/choke/glow plug is first switched followed by fuel pump. Next ECON
cranks the engine. Crank command is withdrawn once the engine start which
is detected, either by LLOP pressure or by build-up of generator voltage, as
per the setting by the user. Max duration of crank command is user settable.
In case of non-start of the engine ECON re-cranks it till it starts or user
programmed crank attempts are exhausted. If generator fails to start after the
maximum programmed crank attempts, Fail to Start LED starts blinking,
indicating start failure and the hooter is switched on.
After successful start of the generator, it is allowed to warm up for a user
programmed time before the load is transferred to generator.
While the generator is running ECON monitors it for external fault (Digital
Inputs: Emergency, V-Belt, RWL,, LLOP Switch etc) and internal faults
(Measured Values faults: LLOP, HWT, Fuel, Over Load, voltage and
frequency).
On persistence of any fault for more than the programmed supervision
delay,for that fault, generator is stopped, corresponding fault is announced &
hooter is switched on. On restoration of healthy mains supply, continuously,
for the programme duration the load is transferred to the mains and generator
is stopped after expiry of re-cooling time. In case mains again become
unhealthy during the re-cooling period the load is switched to generator.
After successful stopping of the generator either normally or on fault the Fuel
Pump Contact is removed. In case of fail to stop, the Fuel Pump Contact is
not removed to avoid air locking.
Cyclic Operation: ECON can be programmed to automatically shut down
the engine, for a predefined duration, after a predefined duration of
operation, even if the mains is unhealthy. In case the mains continue to be
unhealthy this cyclic operation will continue till the mains is restored.
• 10.1.2 Semi Auto Mode
Semi Auto Mode is sub set of Auto mode. This mode can be selected by
pulling the pin 28(Semi/Auto) low and selecting auto mode from the front
panel. The Auto LED will blink indicating that the unit is in Semi-Auto Mode.
In this mode the unit does not automatically starts the engine after the mains
has failed and mains supervision timer has expired but waits for an external
start signal pin 29(Remote Start/Stop). Once the start signal is given the unit
now functions like auto mode with 3 crank attempts. The unit can be stopped
by pulling low Pin 29(Remote Stop). Both Remote start and remote stop are
one touch and hence should not be continuously activated. These pins shall
only function during semi auto mode.
• 10.1.3 Manual Mode
ECON-A, in this mode is under the manual control of the operator for starting
and stopping of the generator. Engine has to be started manually by manually
pressing “Start” switch. The “Start” switch shall not operate if GCB contact is
closed, to provide protection to generator. Once the generator is started the
load can be switched to generator by pressing “GCB” switch or to mains by
pressing MCB switch. At any given time, either of GCB or MCB can be
operational. Attempt to switch on GCB while MCB is on will be ignored and
vice versa. Both MCB and GCB key have dual function of either switching
ON or OFF the respective contactor. A press shall toggle the state.
Continuously pressing these keys shall keep toggling the status. To stop the
generator, switch off the GCB contactor and press “STOP” key. Any attempt
to stop the generator, while the GCB contact is engaged, shall be ignored.
While the generator is running ECON-A protects the generator by monitoring
all internal and external faults.

• 10.2 MCCB Shunt trip or Auto Stop Mode (ECON-A , ECON -A-4C or
ECON-S)
This mode is a mix of Manual and Auto mode. In this mode the engine is
manually started but its shut down on the restoration of the mains. To make
sure that the engine is not shut down on load and also to recool the engine
before shutting it down it has provision to activate the shunt trip coil of MMCB
before shutting it down it has provision to activate the shunt trip coil of MMCB
and isolate the generator from load and engine is stopped after running it for
the predefined recooling time.
Engine can be started or stopped either the front keys or remotely by use of
Remote start/stop keys. ECON will monitor the engine and alternator for any
fault and take corrective action
• 10.3 Manual Controller ( All models)
This mode is a pure manual operation mode. The engine has to be manually
started and stopped. The responsibility of disengaging the load from
generator and allowing the engine to cool before stopping has to be
performed by the operator. The engine and Alternators are protected while
the engine is running.
*RTC Based operation :
In ECON-M/ECON-S and other models when used as manual controller the
RTC based start stop can be activated. If activated the engine can be made
to automatically start at a given time of the day and stop at a predefined time.

Contactor
Protection
In case of the unit placed under

condition and the mains voltage falls
below the safe limit of the contactor,
the contactor burns after chattering.
This can be avoided by enabling this
protection. If enabled the mains
contactor shall drop if the mains
voltage becomes unhealthy and the
contactor will again engage after the
mains voltage turns healthy

• 14.0 Load Management
ECON-A has programmable contact Load management function. The load
management contact will switch on when the current on the generator
has crossed a programmed limit and will reset when the current has fallen
below the reset programmed limit. This function can be used to cut-off
unnecessary loads or start a second generator when the load goes above a
limit.
• 15.0 Event Recording:
ECON keeps a log of last 64 events. Setting change and warning are
considered as event. Events are stamped along with date and time
• 16.0 Faults
ECON keeps a log of last 64 Faults. These Faults are stamped along with date
and time There are two categories of faults
• Internal Faults
• External faults
• 16.1 Internal Faults
Internal faults are the faults, which do not need any external signals and are
detected by the system itself. They are:
• Generator Fails to Start. • Generator Voltage Unhealthy
• Generator Frequency Unhealthy. • Generator over Speed.
• Generator Fails to Stop. • Over Load
• 16.2 External Faults
Those faults which cannot be sensed by the unit itself (these faults are not
reflected by the generator voltage) and are to be provided externally. They are:
• LLOP • HWT • Oil Level
• RWL • Fuel • Oil Temp.
• Emergency • V-Belt • Earth Fault
• 16.3 Fault Reset
Internal Faults & LLOP fault:
All internal faults and LLOP fault can be reset by pressing (R) switch after the
generator is stopped. External Fault except LLOP & V-Belt faults:
These faults cannot be reset till the engine is running and/or fault conditions
persist. Once the faults are rectified, the fault can be reset by pressing Reset
switch (R). In case the engine fails to stop “STOP KEY” can be pressed for
manual attempt to stop engine
