Still FM14:
error codes

Hi guys,
Kindly assist in solving error nos.06,07,33,54 on STILL FM14 REACH TRUCK.
When this errors appear its very difficult to start the machine.
Thank you

Hi John,

* As a note, if any of the three micro switches in the emergency stop button fault these machines can throw up all sorts of miscellaneous codes, so i'd suggest checking this first.

FE77, 24V error at the LAS module
There is no 24V signal at pin X10.35 when the vehicle is switched on. Both safety relays K1 and K2 are switched off by the ÜWA-CPU. No vehicle functions other than the steering can be used.
Check the wiring and if it is OK, replace the LAS module (see "LAS module, Safety monitoring, Block diagram").

FE80, Excess voltage/undervoltage at the steering.
The supply voltage of the steering is faulty. Check the power supply at X47 (see "Steering, Steering unit, Connections"). If this is OK, replace the steering unit.
Remark: The supply voltage is checked by the main steering contactor 3K1. This error code is also issued if the contactor is faulty.
The brake closes, travel is blocked.

FE42, CAN bus 2 communication error between FPS and travel
converter.
The FPS is not receiving any data from the travel converter. The main contactor K1 is opened.
Check that the CAN bus 2 wiring and bus terminal are correct (see "CAN bus, Bus structure CAN 2").
If the CAN bus is OK, the converter must be replaced. To test whether the converter is the problem in faulty bus communication, the component can be contacted directly via the onboard diagnosis of the display (Software version query, see "Display, Onboard diagnosis, Software version query"). If Version 0.00 appears on the display when the query is made (see "Display, Onboard diagnosis, Error codes") the component is faulty.
Remark: (Converter to 04/2005). This error message is also issued if the 48V supply voltage is missing at X1.1 of the converter (see "Converter, Status LED"). This is, for example, the case when the emergency-stop button has been actuated.
This error can also be caused by an incorrect converter encoding (cf. "Converter, converter encoding").
Remark: (Converter from 05/2005) If the 24 V supply voltage is missing at X1.15 of the converter, this error message also appears. Also if the connection FPS X1.12 -- travel converter X1.11 is interrupted when switching on the truck (cf. "Converter, supply and enabling (from 05/2005)")

Good luck.

Service life of a forklift is proportional to how well it is maintained.
Dez_A, the equiment was working Well after sorting out the reach problem untill today morning that it developed a new error 77 80 42.
I don't have the still workshop error manuals yet. Help me solve these errors once more.
Thank you,
John Juma.

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.

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.
