Telescope length
REQUIREMENTS DEFINITION
BLDL001
The machine positions are defined and checked by the following sensors when machine is dual load
enabled :
• SQ530: Magnet detector to set the position telescope, SQ533 redundancy, pull down input (active state :
ON=5V)
• SQ531: Magnet detector to set the position telescope in, SQ530 redundancy, pull down input (active
state : ON=12V)
• SQ533: Mechanical switch to set the length of telescope, pull down input (active state : ON=5V)
• SQ532: Magnet detector to set the zone of accepted change in SQ531 sensor state, pull up input (active
state : ON=12V)

The length failure is defined as follow It is the result of the securing of SQ531 :

0 Down 2
1 Up 4
1 1 8
1 1 16
If a length failure has been detected, is reset (VAR[LengthErr]=0) only if the telescope is totally folded
(SQ5) only if the telescope is totally folded (SQ533=1 && SQ532=0 && SQ530=1 && SQ531=1).
BLDL003 The length failure is reload after each restart if it has not been reset.
