Volcano SC300 Owner's Manual

1. ABS BRAKING - The ANTI-LOCK BRAKING option available in the VOLCANO is
designed to operate much the same way as do ABS brakes in full-size vehicles. By
eliminating brake locking, the VOLCANO will provide improved cornering and stability
especially suitable to on-road and touring vehicles.
2. OVER-TEMPERATURE SAFETY CUT-OUT - If at any time the temperature of the
VOLCANO exceeds maximum ratings, the OVER TEMPERATURE SAFETY CUTOUT
will temporarily shut off power to the motor to prevent permanent damage to the unit. If
this happens repeatedly, make certain that your vehicle's drive train is free of binding,
that the motor pinion is meshed correctly to the spur gear and that there is nothing
restricting the rotation of the wheels. If this does not solve the problem, verify that your
motor is in good working order and that the brushes are seated properly. Finally, make
certain your motor's current requirements do not exceed the VOLCANO'S maximum
limits. You may need to increase the number of windings or gear the motor lower.
3. PUSH-PULL PAUSE PROTECTION - In a typical ESC, jamming the throttle from full
forward to full reverse too quickly can cause damage to the motor and place excess
stress on the batteries as well as the drive train of the vehicle. By means of a built in
pause timer circuit, PUSH-PULL PAUSE PROTECTION prevents damage to the vehicle
by sensing the motion of the wheels, ensuring that the wheels cannot spin backwards
before the vehicle has stopped moving forwards. The combination of PUSH-PULL
PAUSE PROTECTION and ABS braking greatly enhances handling and control in a
racing environment.

OWNER'S MANUAL
NOTE: PLEASE READ MANUAL COMPLETELY BEFORE OPERATION
INTRODUCTION:
Thank you for purchasing the FMA Direct / RCLine VOLCANO reversible, high
performance, sport electronic speed controller (ESC). The VOLCANO is one product in
a family of quality ESC devices available from FMA, Inc. Designed from the ground up to
offer fast and efficient throttle control and standard or ABS braking, the VOLCANO is
designed around state-of-the-art, high current / low loss HYPERFETS. Capable of
turning a 12 turn motor at 30 amps continuous power, the VOLCANO is the perfect step-
up from mechanical, less reliable speed controllers. Featuring high-frequency operation
and advanced power filtering, this microprocessor controlled ESC will provide you with
smoother throttle response, better acceleration and braking in curves or on straight-
aways, longer run-times, and improved radio reception through lower noise. Packed
with extra features like EZ SETUP, which makes it a snap to interface your ESC with any
R/C system, over-temperature safety cut-out, and push-pull pause protection, the
affordably-priced VOLCANO has everything you need to stay ahead of the competition
without breaking your budget!
