_1244Operation

Lifting stroke greater than 2x

free lift, however mast lift

has not been detected

Integrated lift stroke is greater than 2x the set free lift

height, however sensor indicates free lift. When the

event occurs, the master assumes that the truck is in the

mast lift stage.

-Check wire connection;

-Check sensor and replace if necessary;

_1245Operation

“Lift limit switch redundant

inputs” logic implausible

The event message is triggered

if for T = 100 ms the following applies:

•NC and NO contacts have the same status

-Check wire connection;

-Check sensor and replace if necessary;

-Replace signal-evaluating controller;

_1246Operation

“Initial lowering limit

redundant inputs” logic

implausible

The event message is triggered

if for T = 100 ms the following applies:

•NC and NO contacts have the same status

-Check wire connection;

-Check sensor and replace if necessary;

-Replace signal-evaluating controller;

_1247Operation

Logic: lift system limit

switchfaulty.

No positive signal at 7B38.1 - 7B38.4 during lifting or

lowering.

-If possible, do not use the lift system, as the lift

limit is deactivated. The lift mechanism could

move too far and be damaged;

-If absolutely necessary, carefully lower the

platform manually. Note that lowering must end

as soon as the shuttle can move freely

underneath the pallets;

-Check limit switches 7B38.1–7B38.4; check

signal feedback at inputs R3–R6 of the main

controller 8U37;

-Check the wiring;

_1248Operation

Lift stroke greater than 1.5x

free lift, however mast lift

has not been detected

Integrated lift stroke is greater than 1.5x the set free lift

height, however sensor indicates free lift.

When the event occurs, the master assumes that the

truck is in the mast lift stage.

Event is reset when mast lift is detected.

-Check free-lift sensor (position, contamination);

-Check free-lift height setting (JUDIT);

-Check pump drive (e.g. worn pump?);

_1251Operation

Signal on load sensing

inputs is implausible

During operation combinations 0/0 and 1/1 trigger the

event message. The event message can only be reset

by resetting the truck. The activation limit is 2000msec.

-Check wiring with multimeter;

-Check sensor system with multimeter;

-Check computer component inputs;

-Repair faulty components and replace if

necessary;
