2.2 What to Do in an Emergency
In case of an emergency such as a fire or collision, you should stop the AMR quickly and
safely.
CAUTION: Combustible Lithiumî ±Battery. For AMR fire suppression, use
either a type D foam or dry chemical extinguisher, or a CO
2
extinguisher.
The LD-250 has two E-Stop buttons, one on either side of the chassis (a red push-lock button
on a yellow background). The Operator Panel (if used) provides an additional E-Stop button.
Use the User Interface port to add E-Stop buttons to your payload structure, if required. See
User Interface (Brake and E-Stop) on page 103

A user-initiated E-Stop differs from a laser-initiated emergency stop. The latter occurs when the
AMR's safety scanning laser detects an object within its protected zone. In such cases, the

Emergency Stops that are Initiated by AMR Safety Lasers on page 39.
To use an E-Stop button:
1. Push firmly on the red button until it locks:

The AMR uses motor power to come to a controlled stop then engages its motor
brakes and cuts power to its drives.
l
Indicator lights on the AMR show the E-Stop state.
2.
Follow your site-specific emergency and safety procedures.
After correcting the emergency condition, press and hold the brake button to manually move
the AMR. You can also use the joystick to drive the AMR manually, if it is safe to do so.
To enable the AMR's drive motors and put it back into service, follow the procedure described
in: Releasing an E-Stop.
Releasing the Brakes to Move the LD-250 Manually
You can move the LD-250 manually when required. For example, if the battery is too depleted
to power the LD-250 or any other urgent condition. For safety reasons, only qualified persons
should move an LD-250 manually.
NOTE: You should move the LD-250 manually only when absolutely necessary
during an emergency, for safety, or if it is lost or deadlocked. If you find that you
