Stability Alarm F27 F30

Screen Image 27 = FRONT CRANE 30 = REAR CRANE
Explanation	The arms have been extended to the edge of the safe working envelope on the stabiliser side of the Sidelifter All arm functions that could move the load further away from the trailer are disabled If the top arm is above horizontal, then only top arm up function will be allowed If the top arm is below horizontal then only top arm down function will be allowed Bottom arm up function is disabled Bottom arm down function is enabled
Causes	If within safe working envelope then angle sensors or their calibration may be faulty Stabiliser magnetic counter error Top arm pressure sensor error
Operator Actions	Move arms back within the safe working envelope If the load IS within the safe working envelope then use override code to continue operations Request service
Service Tasks	Check the operation of the stabiliser extension magnetic counter by going to VIEW SENSOR VALUES then FRONT or REAR STABILISER EXTENSION SENSORS. As the stabiliser extension is deployed the LCD display screen should display a changing count as the magnetic counter reads the magnetic strip. With the stabiliser extension fully extended, the magnetic counter should display as 1 and the top reset magnet should display as 0. With the stabiliser extension arm fully retracted the magnetic counter should display as 0 and the top reset magnet should display as 1 Check the calibration of the stabiliser, bottom and top arm angle sensors. Do this by hanging a plumb bob one at a time between pins A&D, D&G and H&L as described in the calibration procedure SL0005 and then go to the MANUFACTURERS AREA then VIEW PIN DISTANCES and check that the HORIZONTAL DISTANCES, AD, DG and HL are zero mm (ą10mm) when the plumb bob is lined up
