Safety Direct Features Safety Direct Rugged Enclosure


The Safety Direct has three E-stop modes: a RUN mode, a PAUSE mode, and a DISABLE mode. Run and pause can be controlled at will, remotely causing the vehicle to start and
stop operations. Disable is very similar to an E-stop actuation and requires that it be reset at the vehicle and NOT at the remote control location.

The vehicle responds to the E-stop outputs as follows:
• E-stop RUN mode enables the vehicle for movement.
• E-stop PAUSE mode brings the motion of the vehicle to
a prompt stop, with brakes applied to hold the vehicle
even on a slope. The vehicle should be ready to resume
forward motion when the E-stop re-enters RUN
• E-stop DISABLE mode brings the vehicle to a prompt
stop and shuts down all propulsion systems while
actively applying and maintaining the brakes.
