L405 Mast lifting is active but it is not allowed to

LAC Lift L405

Description
Mast lifting is active but it is not allowed to

1) Mast lifting is considered as "active"... at "Li"-trucks: [X1:11 - X1:31] > 5V... at "sLi"-trucks: ["+" of powerpart - "Li" of powerpart] > 5V
2) The reason why mast lifting it not allowed to be active is bitwise coded in additional data 1
3) The time condition for each bit is the value displayed at additional data 2 plus certain tolerances
Bit 0: Tiller in horizontal rest position (Pathfinder >> Monitoring >>Traction >> Tiller Foot Poti >> "Status Of Tiller" = 3 )

Bit 1: Tiller in vertical rest position (Pathfinder >> Monitoring >>Traction >> Tiller Foot Poti >> "Status Of Tiller" = 2) and creep speed switch not pushed (Pathfinder >> Monitoring >>Traction >> Creep Speed Switch >> Status Of Creep Speed Switch != 1)

Bit 2: Tiller in any rest position (Pathfinder >> Monitoring >>Traction >> Tiller Foot Poti >> "Status Of Tiller" = 1) and creep speed switch not pushed (Pathfinder >> Monitoring >> Traction >> Creep Speed Switch >> Status Of Creep Speed Switch != 1)

Bit 3: Belly button is pushed (Pathfinder: Monitoring >> Traction >> Belly >> "Status of Belly" == 2)

Bit 4: Mast lifting/lowering command (Pathfinder >> Monitoring >> Lift >> Mast Command >> "Status of Mast Command != 6") and rear mast lifting/lowering command (Pathfinder >> Monitoring >> Lift >> Rear Mast Command >> "Status of Rear Mast Command != 6" ) are both not in "mast lifting position"

Bit 5: If using "double stacker"-mode configuration (Pathfinder: Parameters >> General >> Current Settings >> "Stackermode = 1")

1) Mast forks are above height limit and initial forks are not down (X1:23 > 7,2V). At "double stacker" -mode the mast lifting above the height limit is allowed only when the initial forks are down

2) If using "standard stacker"-mode configuration (Pathfinder: Parameters >> General >> Current Settings >> "Stackermode = 2"). Automatic initial lowering is not active. At "standard stacker"-mode the initial forks must always be lowering while mast lifting is active.

About the height limit:

If the mast is equipped with digital sensors: The height limit is defined by the location of the sensor, usually at 1500 mm or at 1800 mm. If the truck is equipped with a Lift Height Sensor: The height limit is 1800 mm, according to development of 26-Apr-2018. The defintive height limits in series trucks may differ.

Bit 6: not used

Bit 7: Mast lifting commands have not been released at least one time after key-on. (Pathfinder >> Monitoring >> Lift >> Mast Command >> "Status of Mast Command != 6") and (Pathfinder >> Monitoring >> Lift >> Rear Mast Command >> "Status of Rear Mast Command != 6")

Conditions of occurrence
---

Result
Immediate deactivation of all functions (brake, traction, lift pump, valves, main contactor, safety relay, castor wheels, FAN)

Possible causes
Bit 1: Reasons may be: Bouncing creep speed switch signal

Bit 2: Reasons may be: Bouncing creep speed switch signal and/or bouncing tillerfoot switch signal X1:33
