Hyundai HL930A, Operation & Maintenance Manual

Page: 49 / 262

It is unlawful to tamper with or remove any component of the aftertreatment system. It is
also unlawful to use a Diesel Exhaust Fluid (DEF) that does not meet the specifications
provided or to operate the vehicle/equipment with no Diesel Exhaust Fluid (DEF).
Safety Requirements for DEF and SCR system
The DEF/AdBlue
®
level gauge should be checked daily, and if the DEF/AdBlue
®
warning lamp and
DEF/AdBlue
®
fill up warning lamp are activated, it is recommended that the the DEF/AdBlue
®
is filled
completely full in order to correct any fault conditions.
Allowing the DEF tank to become empty will cause the aftertreatment DEF dosing system to lose prime.
A loss of prime condition may cause fault codes to become active.
If corrective action is not taken within 30 minutes of the Check engine lamp illumination, the engine will
enter the final derate level, which may include throttle lock or engine shutdown with possible restart limi-
tations.
It is recommended that the DEF tank be filled completely full of DEF in order to correct any
fault conditions.
If the engine has been shut down or has idled for an extended period of time after the DEF gauge indi-
cates empty, the Stop engine lamp will also be illuminated along with the flashing DEF lamp and illumi-
nated Check engine lamp. The engine will enter the final derate level which may include low idle lock or
engine shutdown with restart limitations.
In order to remove the final derate, the DEF tank must be filled to above 10 percent gauge
reading. It is recommended that the DEF tank be filled completely full of DEF in order to
correct any fault conditions.
The use of DEF/AdBlue
®
meeting ISO 22241-1 is required. There is no acceptable substi-
tute.
Some locations may reference the DIN 70070 standard. Diesel Exhaust Fluid specification
limits of this standard are identical to ISO 22241-1.
Safety Requirements for fuel
The engine has been optimized for use with an exhaust aftertreatment to meet the Tier 4 Final/ Stage V
off-highway emissions regulations. It must operate on Ultra-Low Sulfur Diesel (ULSD] with a maximum
sulfur content of 15 parts per million (ppm) in the United States and 10 ppm in the European Union. Fail-
ure to do so can permanently damage engine and aftertreatment systems within a short period of time.
This damage could cause the engine to become inoperable and affect the warranty coverage on the en-
gine.
Ultra-low sulfur diesel fuel, also defined by ASTM S-15, is defined as diesel fuel not exceeding 0.0015
(15 ppm) mass percent sulfur content. There is no acceptable substitute.
At operating temperatures below 0°C [32° F], acceptable performance can be obtained by using blends
of number 2D and number 1D.

(1) Any adjustment to compensate for reduced performance with a fuel system using alternate fuel is
not warrantable.
(2) Winter blend fuels, such as those found at commercial fuel dispensing outlets, are combinations of
number 1D and number 2D diesel fuel, and are acceptable.
