Operator Cab and Controls - Section 32 08/11 OM3212 Page 32-30 This screen is displayed after i1 and before engine is started. It is used to inform the operator whether the conditions are acceptable to start the engine. 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 steer- ing accumulator pressure is too low, or "ENG. DERATE ON" when the engine system detects some severe fault which makes the engine power derate.
When "MOM" judges that engine start is acceptable, "ENGINE START OK" is indicated on the screen. If "MOM" judges that engine start is not acceptable, "ENGINE START WAIT" is indicated on the screen. The reason why the engine start is not acceptable is also indicated at the same time. If the screen dis- plays "PARKING BRAKE" , it means the parking brake is not applied. If the screen displays "T/M SHIFT LEVER", it means the shift lever is not in the NEUTRAL position. The truck is still able to depart even is "STRG.PRES- SURE TOO LOW" or "ENG. DERATE 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. The engine will still start even if the screen indicates "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 ini- tial check, Check 2, screen i3 automatically. If any controller detects a fault, i3 is changed to the warning message screen i6 automatically. If any controller detects a fault, i2 is changed to the i6, Warning Message screen 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 posi- tion. 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 depar- ture is acceptable or not. When "MOM" judges that departure is acceptable, "DEPARTURE OK" is indicated on the screen.
Time, current payload, total payload, and total num- ber 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.
