8 ALO equipped system - PMERail - Max and Ultra
Systems with slew limiting enabled will allow a limit to be set on one side
of the machine perpendicular to the track. The Artic pivot pin (if fitted),
arm pivot pin and tool point are monitors along with the corner of the cab,
battery box and counterweight. See section 16 for monitored points on the
machine. PMERail is NOT aware of any attachment fitted, therefore
where an attachment is in use, limits should be determined and set in accordance with
the safe system of work.
With a limit set, the system will:
 Activate an amber lamp to show a slew limit is active
 The slewing speed of the machine will be reduced to one of three possible states:
 Linear speed at the tool point will be no greater than 2 m/s when MORE than 2m
(default) away from the set limit.
 Linear speed at the tool point will be no greater than 1 m/s when LESS than 2m
(default) away from the set limit.
 Linear speed at the tool point will be CONTROLLED by PMERail when LESS than
1m (default) away from the set limit. If the tool point reaches 1m (default) away
from the limit, PMERail will:
 Motion cut slew at 1m (default) from the limit to allow PMERail to take over
slew control in the direction of slew travel only.
 To re-enable movement toward the
slew limit, the slew joystick must be
returned to the neutral position then
back towards the limit. The warning
message show here will be dis-
played, linear speed at the tool point
will be no greater than 1 m/s in this
state.
 It will be possible to move away from a limit at anytime, the linear speed at the tool
point speed will be increased back up to no greater than 2 m/s.
 The counterweight will not induce the 1m/s state even if it comes within 2m of the
limit.
Care should be taken to test that the limit is set correctly. Observe the operational limita-
tions given in section 3.
