I HAVE A GENIE ZX 135/ 70 Showing on TCON secondary boom extend retract and secondary boom up down flow valve calibrations. Can I calibrate theses from the
platform. Also when secondary boom comes down so far I get RSS1AO fault the alarm
sounds and the secondary boom will not go down completely to stowed position.I can
bring primary boom down to stowed position but moves very slowly. Also secondary boom
will not extend when I clear fault and rise fully it shows 58 degrees and RSS1AO fault is not
showing. RSS1AO sensor has been replaced and primary and Secondary boom calibrations have been done twice by procedure with bypass key in right position and logged properly.When the boom comes down to a certain position the RSS1AO alarm and fault are active then will come down very slowly but secondary boom will not go into complete stowed position.This has been calibrated in the stowed position at -3.5 degrees with a digital potractor
