Explanation
Runaway output
LED must be on when the system is running normally
When the LED is off, the rotate motion controller has made an
emergency stop
Output for driving the table inwards
Active low
Output for driving the table outwards
Active low
Output for driving the hand controller LED
Active low
Debug use only
Dimly lit during normal operation (timer interrupt running)
Lit if the detectors are too close to the table or the gantry base
The system can only be operated using OVERRIDE on the
hand controller
Flashes with a frequency of 0.5 Hz when the controller is
running
If the power-up self test is succesfully passed, this LED is lit
If the Node ID (CAN Bus address, switch 1 – 5) is incorrect,
(i.e. neither rotate nor linear), this LED flashes
If the supply voltage to the controllers dips, the controller
stops normal operation and this LED flashes with a frequency
of 1 Hz
Light is roughly proportional to the motor control voltage
output when positive
Light is roughly proportional to the motor control voltage
output when negative
