8.4.4 Machine Envelope Indicator (MEI) - Low
If any of the equipment enters the approach limit* a ‘Close to min height’ message will ap-
pear, the internal alarm will sound and the amber LED will be lit.
If any of the equipment reaches the low limit, the internal alarm will sound and the RED
LED will be lit.
*The approach limit is configurable at point of calibration, check system operation before
commencing work.
MEI systems will not cut
motion to any section of
equipment that has
reached a limit. This can
lead to the a breech of the
set limit.
Once a limit is set, the internal alarm will sound and the RED LED
will light if the equipment exceeds the current limit. Always check
that the current limit activates at the set point. The restriction cannot be de-
activated if in the alarm state. Observe the operational limitations given in
section 4.
