8.1.5 Machine Envelope Controller (MEC) - Height
If any of the equipment enters the approach limit* a ‘Close to max height’ mes-
sage will appear, the internal alarm will beep and the amber LED will be lit. If any
of the equipment reaches the height limit, the appropriate motions will be con-
trolled.
If any of the equipment reaches the height limit, the internal alarm will sound and the
RED LED will be lit and the appropriate motions will be controlled.
*The approach limit is configurable at point of calibration, check system operation before
commencing work.
See sections 4.1 and 7.6 for hydraulic override details.
MEC systems will cut mo-
tion to any section of
equipment that has
reached a limit but allow
other sections to operate
unhindered unless they too
reach the set limit.
Once a limit is set, the internal alarm will sound and the RED LED
will light if the equipment reaches the current limit. Always check
that the limit activates at the set point. A limit cannot be deactivated when
close to or at the limit. Observe the operational limitations given in section 4.
