SHORT and OPEN CIRCUIT ERROR DETECTION:
If power is applied to the controller while connected to an existing short circuit, the module will not detect this or
show an error led and will output PWM current equivalent to the Imax setting.
The module ( which should be protected by an AGC5 fuse as reccomended ) will be regulating and will not
damage itself in this mode, but the issue can only be diagnosed by using the GUI and observing that the current
is changing but the PWM% is only moving to a max of ~5% of max output.
If power is applied to the controller while connected to an existing open circuit, the module will not detect this or
show an error led until the PWM output is commanded to control current.
