The following tables contain information about the different possible failures that could occur for each module
subsystem. In most cases when an error is detected, a message will be presented on the master display together with
an error code on the module. In some cases, the module will turn off or at least shut down the outputs, to increase
safety.

3 +VREF Short-circuit to -VREF VREF error => VIN out of range, will create a VIN
error => VIN=Predefined error value. (a)
4 +VREF Short-circuited to +BAT VREF error => VIN out of range, will create a VIN
error => VIN=Predefined error value. (a)

error => VIN=Predefined error value. (a)
6 -VREF Short-circuited to +BAT External fuse (if <7.5A) on +BAT blows.
7 -VREF Short-circuited to -BAT Not detected.
