High Temperature Shutdown
Internal temperature of the crawler is monitored at all times during manual driving. Maximum
recommended internal operating temperature is 50°C. If the internal temperature exceeds 50°C, the
system will automatically disable all motors and a warning message will be displayed. Once the warning
has been acknowledged, operation is allowed to continue but is not recommended. Permanent damage
can result from operation at extremely high temperatures.
