Short-circuit detection
The diagnostics for short circuit to ground can be configured for the voltage output type.
Short-circuit detection is not possible for low output values. The output voltages must
therefore be under -0.1 V or over +0.1 V.
Wire break detection
The diagnostics for wire break can be configured for the current output type. Wire break
detection is not possible for low output values; the output currents must therefore be below -
0.2 mA or above +0.2 mA.
