LED Indicator Light
The RVB-Series PowerRolls are equipped with an electronic control board to monitor and control the high
current required to move the heavy loads for which they are designed.
The LED indicator on the top of the back plate provides feedback on the status of the machine and warnings
if the machine is being used is a way which can potentially cause damage.
Explanation of LED Functions:
When a battery pack is installed the LED will flash green once and remain off until the throttle is
actuated. This simply indicates power is on and throttle input is being seen.
The LED will turn on whenever the throttle is actuated and go off when throttle is not actuated.
The LED will glow solid green anytime machine is within the normal operating temperature or safe
operation mode.
The LED will start to flash red quickly when the motor temperature is higher than normal operating
temperature, but the PowerRoll will still function. This is intended to serve as a warning / feedback
to the operator. The LED will continue to flash red quickly until the motor cools down to normal
operating temperature - even when throttle is not actuated. High motor temperatures are most
likely caused by a) stalling or near-stalling under heavy loads; b) a combination high load and high
duty cycle operation
If the motor temperature continues to rise after being in the rapid flashing red
“warning mode”, it
will eventually switch to “overheated” and
the machine will be disabled to cool down and the red
LED will flash slowly. Slow flashing will continue while the PowerRoll remains disabled until the
motor returns
to the “warning” temperature set point (rapid flashing).
