Showing items 1 - 5 of 5 results.
FE53, Transverse reach potentiometer wire breakage
The two values of the setpoint potentiometer for left/right-hand transverse reaching (arm 1
and arm 2) are outside the monitoring range of 8.5 - 11V on addition.
Check the wiring between the potentiometer and the LAS module. If this is OK, replace the
potentiometer or lever.
The transverse reach function is blocked.

Service life of a forklift is proportional to how well it is maintained.
Thanks a lot again Daz_A,
I did change the hydraulic converter and error code 33 was sorted out, and again I did replaced the drive potentiometer and error codes 06 and 07 never appeared again.
The truck is in operations now even though I still do have a problem with error 53 which do appears.
Do you have an idea about this error 53?
Kind regards,
John Jumaw

Hi Juma,

FE06, Travel transducer already actuated when the vehicle is switched
on or travel transducer actuated without deadman switch. If a "travel setpoint" signal (U>5.5V) from the travel transducer 1U20 is already detected
when the vehicle is switched on, before the main contactor K1 closes, or if the travel transducer is actuated before the deadman switch 1S25 (incorrect operating sequence), the travel function is blocked.
Check travel transducer 1U20, deadman switch 1S25 and the wiring. Maintain the correct operating sequence.

FE07, Travel transducer switch does not close or is already closed
when the vehicle is switched on. When the FPS detects a "travel setpoint" signal (U>5.5V), the micro-switch of the travel transducer must also be closed. If it does not close, travel is not permitted.
The same error message is also issued if the micro-switch of travel transducer 1U20 is already closed during the switching-on process.
Check the travel transducer (see "Travel transducer").

FE33, Hydraulics converter internal fault. The internal safety circuit in the converter has detected a fault. The output power is
switched off. The converter must be replaced.

FE54, Potentiometer outside zero window.When the vehicle is switched on, the setpoint from the potentiometer for main lift, reaching, tilting or transverse reaching is not within the defined zero point window, i.e. a hydraulic function is already selected when the vehicle is switched on. The function in question is blocked. Check the potentiometer and replace if necessary.
Remark: The zero window can be adjusted with the service software (see "Service software").

Hope this helps.
