Unit Protection Devices
Low Oil Pressure Switch:
Engine oil pressure
should rise immediately on starting. The
controller will stop the engine if oil pressure drops
below 117 ± 21 kPa, (1.17 ± 0.21 bar), (17 ±
3 psig) for more than 30 seconds, and the oil level
drops below 8 qt (7.6 litres) (Also see oil level
sensor below). The controller then records an
alarm.
Oil Level Sensor:
An oil level switch closes if the
oil level drops below 8 qts. (7.6 liters) and the oil
pressure drops below 117 ± 21 kPa (Also see low
oil pressure switch above). The controller will
stop the engine if the switch stays closed for more
than 30 seconds. The controller then records an
alarm.
Water Temperature Sensor:
The controller will
stop the engine if the engine coolant temperature
rises to 107 C (225 F) for more than 30 seconds.
The controller also records an alarm. The unit will
restart when the coolant temperature drops to 88 C
(190 F).
Dual Voltage Option
A power cable and receptacle wired for 230 Vac
or 460 Vac is supplied as standard equipment with
each generator.
EcoPower Option
EcoPower TM is an option designed to save fuel. A
speed solenoid is mounted on the engine and
controlled by the controller. The controller
monitors the load from the refrigeration unit and
determines if the engine should run in high speed
(1890 ± 10 RPM), or low speed (1560 ± 5 RPM).
The output frequency is 60 Hz in high speed and
50 hz in low speed. The engine runs in high speed
for at least one hour when it is started, and
whenever it shifts from low speed to high speed.
Units equipped with the EcoPower option have
the following decal.

Fuel Level Sensor Option
The fuel level sensor option allows the controller
to log fuel events (see “Fuel Events” on page 74).
Units equipped with the fuel level sensor option
must have the Fuel Sensor turned on in the
Configuration Menu (see “Configuration Menu”
on page 69), and the fuel tank size set in the
System Setup submenu (“System Setup” on
page 62).
Additional Options
Header pin mounting (SGCO clip-on models
only).
WARNING: the unit may start at any time
without warning when the unit On/Off
switch in the On position.
Units equipped with a SG+ controller
feature a Delayed Restart mode. The
controller will make up to three (3)
attempts every 20 minutes to restart the
unit after a Delay Alarm has occurred.
The Delayed Restart mode continues until
the unit has been successfully restarted, or
until a Shutdown Alarm is generated.
Protection shutdown devices that cause an
Delayed Restart shutdown condition
include:
• Low Oil Pressure
• Low Oil Level
• High Water Temperature
