8 Envelope Monitoring
PME200 can be configured for Machine Envelope Indication (MEI) or Machine
Envelope Control (MEC). MEI will give a warning only, MEC will warn, and
prevent equipment motion. MEC is achieved by interacting with the machines
hydraulics, this allows motion to be cut to any section of equipment that has
reached a restriction but allow other sections to operate
unhindered unless they too reach the set restriction.
PME200 can monitor the highest, furthest, nearest and lowest part of the machine. When
setting a limit, either by entering a known value or by positioning the machine at the de-
sired limit, make sure any implement attached is in its least favourable position as the
system is unaware of any implement fitted unless listed in Tool Selection, see section 6.1.
MEC MEI
OFF: when operating without limit the indicator will have a cross
painted on it.
ON: when operating with an active limit the indicator will not have a
cross painted on it.
Care should be taken to test that the limit is set correctly.

Min Radius Limiting
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.
