DESCRIPTION
Status LED 1 Auxiliary Status LED.
Status LED 2 Auxiliary Status LED.
Status LED 3 Auxiliary Status LED.
Status LED 4
Auxiliary Status LED / Digital to Analog
Output.
Status LED 5 Main Status / Error LED.
AC LED 6
Indicates if the DC Buss is Energized
(Voltage Present).
+VCON LED 7
Indicates if Console Voltage Supply is
present.
VDSP LED 8
Indicates if the DSP Power Supply is
present.
Down LED 9
Indicates if the upper console is
commanding Incline Down.
Up LED 10
Indicates if the upper console is
commanding Incline Up.
PWM LED 11 Indicates if console is commanding speed.
Speed LED 12
Indicates the motor is moving via the
encoder's feedback by blinking.
1. LEDs 1, 2, and 3 sequence back and forth to indicate the processor is online and operational.
2. LED 4 is used as a discrete / analog signal to the upper console.
3. LED 5 indicates system status / mode. Currently 3 modes are defined safe mode, stand by mode and run mode. They are defined as
follows:
a) Safe Mode - When the controller's safety relay is not energized and no error exists, LED 5 remains off.
b) Stand By Mode - When the safety relay is engaged but the system is not outputting an active PWM to the motor and no error exists, LED 5
blinks off and on at a fast rate.
c) Run Mode - When the system outputs an active PWM Control signal to the motor and no error exists, LED 5 remains ON.
