The Additional Sensors and Their Setpoints of The Jgs 320 With Gen2 Controller

The document describes several additional sensors and their setpoints on a JGS 320 engine with a GEN2 controller, including a barometric pressure sensor inside the control panel that measures atmospheric pressure, a charge air filter difference pressure sensor behind the air filter housing that compares air pressures, and an oil differential pressure sensor before and after the oil filter that measures the pressure difference to indicate filter clogging. It also discusses sensors for crankcase pressure, charge pressure before the throttle valve, and pressure before and after the blowby filter, as well as details about a Phoenix battery charger.

THE ADDITIONAL

SENSORS AND
THEIR SETPOINTS
OF THE JGS 320
WITH GEN2
CONTROLLER
BAROMETRIC PRESSURE SENSOR

It is located inside the +M panel. Barometric pressure


sensors measure fluctuations in the pressure exerted by
the atmosphere. It is responsible for measuring the
atmospheric pressure of the environment inside the
panel. Different environments will have different
atmospheric pressures, which will have an affect on how
the coolig device operates.

SETPOINTS

WARNING: 60 mbar
CHARGE AIR FILTER DIFFERENCE
PRESSURE

Located exactly behind the air filter housing. It compares the


atmospheric pressure and the pressure of the air inside the
intake housing.

The higher the pressure difference means higher the


restriction in the air flow. This restriction can be due to the
choked air filters.

SETPOINTS
MINIMUM
WARNING: -1 mbar

MAXIMUM
WARNING: -10
OIL DIFFERENCIAL PRESSURE

Two pressure sensors located before and after the oil filter.
The output of the sesors are substracted and the resultant
value is displayed as oil differential pressure on DIA.NE XT4.

Oil differential pressure indicates the difference of oil


pressure between the inlet side (dirtyside) and the outlet
side (clean side) of the oil filter. As the filter becomes
choked, the difference in pressure between the two sides of
the element will increase.

SETPOINTS

WARNING: 0.55 BAR TRIP: 0.75 BAR


CRANKCASE PRESSURE SENSOR

Located on one of the inspection windows. A crankcase


ventilation system (CVS) is a one way, pressure-sensitive
passage which allows the natural build up of gases to escape
from the crankcase in a controlled manner.

Turbocharged engines can have exhaust leakage from the


turbocharger shaft. These blow-by gases, if not ventilated,
inevitably condense and combine with the oil vapor present
in the crankcase, forming sludge or causing the oil to become
diluted with unburnt fuel.Excessive crankcase pressure can
furthermore lead to engine oil leaks past the crankshaft seals
and other engine seals and gaskets.

SETPOINTS
MINIMUM
WARNING: -75 mbar

MAXIMUM
WARNING: 4 mbar TRIP: 20 mbar
CHARGE PRESSURE BEFORE
TROTTLE VALVE (P2)

Located in pairs of two at the inlet and outlet of the core. The
difference of the output pressure from both the sensors is
displayed on DIA.NE XT4.

This parameter will allow us to detect the differencial pressure


of the core and will indicate the condition within the core. The
differential pressure reading will contraindicate whether the
core is choked or not and when the required cleaning needs to
be done.
PRESSURE BEFORE/AFTER BLOWBY
FILTER

Located at both ends of the breather filter. The blowby filter


or the breather filter allows an internal combustion engine to
vent crankcase pressure out of the engine. Despite the name,
it is actually a vent pipe.
By venting pressure out of the crankcase, an engine's piston
rings are allowed to seal tighter against the cylinder walls.
This provides better compression and promotes less oil
consumption.

Often, a breather pipe will incorporate a paper filter that is


designed to catch any oil blow-by that may occur. If the air is
left inside of the engine, the oil would become frothy and
would lose its lubricating properties.
PHOENIX BATTERY CHARGER
(TRIO-PS-2G/3AC/24DC/40 - 2903156)

The TRIO POWER power supply range with push-in


connection has been perfected for use in machine building.
All functions and the space-saving design of the single and
three-phase modules are optimally tailored to the stringent
requirements. Under challenging ambient conditions, the
power supply units, which feature an extremely robust
electrical and mechanical design, ensure the reliable supply
of all loads.
