Haulotte HT23 RTJ O, HT23 RTJ PRO (HT67 RTJ)
Haulotte error code F07.11 — Telescope Length SQ531 / SQ533 / SQ590 / SQ591 General check on angle
Message on the display: Telescope Length SQ531 / SQ533 / SQ590 / SQ591 General check on angle
Code F07.11 occurs in machines: Haulotte HT23RTJ O, HT23RTJ O SW, HT67RTJ O, HT23RTJ PRO, HT23RTJ PRO SW, HT67RTJ PRO.
blocking fault
Telescope Length SQ531 / SQ533 / SQ590 / SQ591 General check on angle position can be done as following : Telescope retracted, horizontal boom : Extend the boom (nearly 1m) : Extend the boom (nearly 8m) : Extend the boom (nearly 8m+) Extend the boom (nearly 8m++) : Extend the boom to high end : Retract the boom (nearly 8m++) : Retract the boom (nearly 8m+) : Retract the boom (nearly 8m) : Retract the boom (nearly 1m) : Telescope retracted, boom down : To erase F07.11 failure if SQ590 and SQ591 are ON: fold the machine, check the position detectors (repair if one is broken), power OFF the machine and then power ON. To erase F07.11 failure if SQ590 and SQ591 are OFF: raise the boom to max position, retract the telescope, fold the machine, check the position detectors (repair if one is broken), power OFF the machine and then power ON. If failure is still active then one of the six detectors defining the machine position is not in the expected state. D [case 1] b0 Incoherence between telescope position sensors : Falling edge on limit switch telescope sensor ( SQ533) out of the allowed zone (in front of telescope zone magnet detector SQ531) [case 2] b1 Incoherence between telescope position sensors : Raising edge on limit switch telescope sensor ( SQ533) out of the allowed zone (in front of telescope zone magnet detector SQ531) [case 4] b2 Incoherence between telescope position sensors : Raising edge on telescope zone magnet detector SQ531 not in allowed zone (limit switch sensor SQ533 inactive) during boom raise or telescope extend [case 8] b3 Incoherence between telescope position sensors : Falling edge on telescope zone magnet detector SQ531 not in allowed zone (limit switch sensor SQ533 active) during boom extend SQ531=↓& SQ533=ON & & (CTRL[Telescope]=O | CTRL[Boom]=U)) [case 16] b4 Incoherence between telescope position sensors : Limit telescope lenght sensor ( SQ531) is inactive with both P1 position detectors in active state

Possible causes
The manual does not list the causes for this code: the service technician establishes them during diagnosis of the machine.
What you can do
Switch the machine off with the emergency stop and switch it on again. If the code comes back, do not use the machine and call service.
What service does
A qualified service technician reads the code with the manufacturer's diagnostic tools, finds the cause, clears the code and carries out a function test.

The descriptions are quoted from the manufacturer's service documentation and are for guidance only. Clearing codes, calibrations and repairs are carried out by a qualified service technician according to the manual for the specific serial number. A machine with an active blocking code must not be used until the cause has been removed.
Does code F07.11 not go away?
RK Rental services Haulotte lifts at our workshop or on site at the customer's premises (construction site, factory, warehouse). We read the code, remove the cause and select the parts by serial number.
