LED Functions
LEDs on the Control Module provide a snapshot of power supply health and system status. During nor-
mal operation, all LEDs should be lit. These LEDs consist of:
48V LED (GREEN): Indicates the state of the 48V supply which powers the Spool Motor.
ON: The power supply is functioning.
OFF: The power supply is inactive. This may be due to a lack of input AC power, a power supply mal-
function, the Main Power Switch being in the OFF position, the Control Cable being disconnected, or
Emergency Stop being pressed.
MAIN 24V (GREEN): Indicates the state of the 24V supply which powers the Motor Brake.
ON: The power supply is functioning.
OFF: The power supply is inactive. This may be due to a lack of input AC power, a power supply mal-
function, the Main Power Switch being in the OFF position, the Control Cable being disconnected, or
Emergency Stop being pressed.
AUX 24V (GREEN): Indicates the state of the 24V supply which powers the Processor, the Tension Arm
and Spool Encoders, the LevelWind Proximity Sensors, and other low-power digital electronics.
ON: The power supply is functioning.
OFF: The power supply is inactive. This may be due to a lack of input AC power, a power supply mal-
function, or the Main Power Switch being in the OFF position.
Unlike other LEDs, this LED should remain ON even when Emergency Stop is pressed or the
Control Cable is disconnected.
ACTIVITY LED (GREEN): Indicates the state of the Motor Driver.
Slow Blink (1 Sec. On + 1 Sec. Off): The Motor Driver is powered but is not yet ready for normal
operation. If the Motor Brake is released in this state, the Motor will add passive regenerative re-
sistance to the rotation of the spool. The degree of resistance is proportional to the speed of rotation,
i.e., attempts by hand to move the spool faster will result in stiffer resistance.
Single Fast Blink (0.5 Sec. On + 1.5 Sec. Off): The Motor Driver is ready for normal operation,
and the winch is currently under PC control.
Three Fast Blinks (3X 0.5 Sec. On + 0.5 Sec. Off): The Motor Driver is ready for normal opera-
tion, and the winch is currently under Local (Joystick) control.
OFF: The Motor Driver is not receiving power and is therefore inactive. This may be due to a lack of
input AC power, the Main Power Switch being in the OFF position, the Control Cable being discon-
nected, or Emergency Stop being pressed. If the Motor Brake is released while the Motor Driver is un-
powered, the spool can be rotated easily with minimal resistance (regenerative braking is disabled).
EMERGENCY STOP LED (RED): Allows the Emergency Stop to be located in dark environments and
indicates its state.
ON: The Emergency Stop has not been pressed, and the system is ready for normal operation.
OFF: The Control Module Emergency Stop and/or Interface Module Emergency Stop may have been
pressed, the Control Cable may be disconnected, the Main Power Switch may be in the OFF position,
or the Control Module is not receiving input AC power.
