114 LD-250 Platform User's Guide 20472-000 Rev B
7.1 î ±Operating Environment
messages as follows:
o
The battery is approaching a high or low temperature limit. Change the LD-250's
operating conditions so that the battery can return to within its ambient tem-
perature limits.
o
The battery has exceeded an initial limit, the LD-250 continues to operate but
charging is deferred until the battery has returned to within its ambient tem-
perature limits
o
The battery has exceeded its temperature limits and the LD-250 will shut down
immediately.
The LD-250 has an ingress protection rating of IP20 and is not liquid-proof. Keep floors dry
because liquids might get into the AMR. Damp, dusty, or greasy floors might also cause its
drive wheels to slip or skid. Such traction problems can affect both braking and accuracy.
Side Clearance
The LD-250 is intended to operate in an environment that has a generally flat and level floor.
There should be no doors or other restricted areas that are too narrow for the AMR to pass
through.
Make sure that you maintain adequate clearance on each side of the AMR, so that a person
cannot get trapped between the AMR and a wall or other fixed object. Consult the applicable
standards for your locale for information about required safety clearances. Refer to the Fleet
Operations Workspace Core User's Guide for information about software parameters that you can
use to control the LD-250's front and side clearance zones. These settings can help to prevent
the LD-250 from closely approaching obstacles.
An exception to side clearance requirements might apply at pickup and drop off locations,
where the LD-250 must closely approach conveyors or other fixed objects.
CAUTION: PROPERTYî ±DAMAGE RISK
Do not allow the AMR to drive through an opening that has an automatic gate
or door unless a properly-configured Call box or Door box is present. Refer to
the LDî ±Platform Peripherals User's Guide for details.
Narrow Passageway Behavior
If the AMR operates in narrow passageways, the following considerations apply:
Table 7-1 Narrow Passageway Performance
Width Mapping and Performance Constraints
1100 mm
(43.3 inches)
AMR can operate at maximum speed.
1050 mm
(41.3 inches)
The AMR can operate up to its maximum speed, but will generally be slower.
Performance improves when the passage is mapped. Unmapped, narrow passages will
degrade performance.
