Operation - Section 3
Page 3-38
The reason why the engine start is not acceptable
is also indicated at the same time. If the screen
displays "PARKING BRAKE", it means the park-
ing brake is not applied. If the screen displays
"T/M SHIFT LEVER", it means the shift lever is not
in the neutral position.
The engine will still start even if the screen indi-
cates "PARKING BRAKE" while the shift lever
must be in the neutral position for the engine to
start. After the engine starts the i2 screen changes
to the second initial check, Check 2, screen i3
automatically.
If any controller detects a fault, i2 is changed to
the i6, Warning Message screen automatically.
3. Screen i3, Initial Check 2
This screen is displayed after the engine is running
but, before the range selector lever is moved from
the neutral position. The indication will be that
departure is acceptable or not.
When "MOM" judges that departure is acceptable,
"DEPARTURE OK" is indicated on the screen.
If "MOM" judges that departure is not acceptable,
"DEPARTURE WAIT" is indicated on the screen.
The reason why departure is not acceptable is
also indicated at the same time. Possible reasons
could be, "STRG. PRESSURE TOO LOW" when
the steering accumulator pressure is too low, or
"ENG. DERATE ON" when the engine system
detects some severe fault which makes the engine
power derate.
The truck is still able to depart even is
"STRG.PRESSURE TOO LOW" or "ENG. DER-
ATE ON" if in an emergency situation. When the
engine is started i2 is changed to the initial check
i3 screen automatically.
If the "LIGHTS OFF" area in the i3 screen is
touched, then the back light of "MOM" is turned
off and i3 is turned to a dark display.
Electronic Displays and Messages
If any controller detects a fault, i3 is changed to
the warning message screen i6 automatically.
4. Screen i4, Normal Display
This screen is displayed while the truck is running
and the range selector is in either a forward or
reverse position. Once the range selector is
changed from the neutral position the i4 screen is
displayed until the key switch is turned to the off
position, even is the range selector is returned to
the neutral position.
Time, current payload, total payload, and total
number of cycles are indicated in this display.
If during the time the i3 screen was displayed the
"DEPARTURE WAIT" was indicated because of
either "STRG." and/or "DERATE", they will remain
on until the cause is discovered and repaired.
The payload meter is the source of the information
regarding payload data. "MOM" is unable to indi-
cate this data until it is sent by the payload meter.
The payload meter will send this information to
"MOM" when it recognizes the truck is in a loading
configuration. It will continue sending information
until it realizes that the loading configuration is
finished or the truck has changed to a dumping
condition. After first recognizing a loading and
then dumping configurations, the payload meter
will then sent the data of total payload and total
number of cycles.
The following situations are considered not nor-
mal.
a. If the truck was in a loading configuration and
the key switch was turned off and then back on
again, "MOM" will indicate no data of current
payload, total payload, and total number of
cycles.
b. The data for total payload and total number of
cycles is not indicated in "MOM" until the pay-
load meter recognizes that the truck has started
dumping the load.
