Cranking; Cold Smart Start; Load Transfer; Shutting Generator Down While Under Load Or During A Utility Outage - Generac Power Systems EcoGen 15 kW Owner's Manual

ler completes the start cycle and runs the generator
through its normal cool down cycle. However, load will
remain on the utility source.

Cranking

The system will control the cyclic cranking as follows:
•
Five cranking cycles as follows: 16 seconds crank-
ing, 7 seconds resting, 16 seconds cranking, 7 sec-
onds resting, followed by three additional cycles of
7 seconds cranking followed by 7 seconds resting.
NOTE: An alarm will be triggered if the generator does
not start after these five attempts.

Cold Smart Start

The generator will monitor ambient temperature when
Cold Smart Start is enabled. The warm-up delay will be
adjusted based on prevailing conditions. Cold Smart Start
is factory-enabled, but can be disabled in the EDIT menu.
See Table 3-2. If the ambient temperature is below a
fixed temperature upon startup in AUTO, generator will
warm up for 30 seconds. This allows the engine to warm
before a load is applied. The generator will startup with
the normal warm-up delay of five seconds if the ambient
temperature is at or above the fixed temperature.

A check for correct output voltage buildup will be per-
formed when the generator engine is started.
If some condition impedes normal voltage creation, such
as frost crystals or dust/dirt preventing a good electrical
connection, the start sequence will be interrupted so a
cleaning cycle of the internal electrical connections can
be attempted.
The cleaning cycle is an extended warming up period
which lasts for several minutes while the normal genera-
tor voltage output is determined to be low. During this
cycle, the generator controller will display "Warming Up"
on the display screen.
The generator controller display will show "Under Volt-
age" if the cleaning cycle fails to clear the obstruction.
After several minutes, the alarm message can be
cleared, and the generator restarted.
If the problem persists, make no further attempts to start.
Contact an IASD.
NOTE: Cold Smart Start warmup is only available when
Off-Grid mode is DISABLED.

Load Transfer

The transfer of load when the generator is running is
dependent upon the operating mode.

Shutting Generator Down While
Under Load or During a Utility Outage
DANGER
Automatic start-up. Disconnect utility power and
render unit inoperable before working on unit.
Failure to do so will result in death or serious injury.
IMPORTANT NOTE: To avoid equipment damage,
follow these steps, in order, during utility outages.
Shutdowns may be required during utility outages to
perform routine maintenance or to conserve fuel.
To turn generator OFF:
1. Set utility MLCB to OFF (OPEN).
2. Set generator MLCB (generator disconnect) to
OFF (OPEN).
3. Allow generator to run for cool-down for approxi-
mately one minute.
4. Set generator to OFF at the controller.
5. Remove 7.5A fuse from controller.
To turn generator back ON:
1. Install 7.5A fuse in controller.
2. Verify generator MLCB (generator disconnect) is
OFF (OPEN).
3. Set generator to AUTO mode at the controller.
4. Generator will start and run. Allow generator to run
and warm up for a few minutes.
5. Set generator MLCB (generator disconnect) to ON
(CLOSED).
6. Set utility MLCB to ON (CLOSED).
The system now operates in automatic mode.
