14.6.2 Input Fault Detection

All inputs support a fault detection which signalises irregular conditions such as small

differential signals, shorts, opens, overvoltages and undervoltages. The fault condition of each

input can be read out by a software parameter. A fault condition remains active until it is

acknowledged by a software command.

Additionally Led S1 signalises the fault condition on LineIn0 and LineIn1. It turns on, when a

fault condition exists and turns automatically off when the input fault is resolved.

Section 14.2 lists the input range, the corresponding logic levels and fault conditions.

Unused inputs should be conﬁgured as single ended and the N-input must be

tight to ISO_GND in order not to get an I/O fault condition.

If an error condition has been detected on an input and signalized by the Line-

Fault parameter, it must be acknowledged by the LineFaultAcknowledge command

in order to use or reconﬁgure the corresponding input again.

Parameter LineFaultUpdate must be performed in order to update the error state.

LineIn0, LineIn1 or LineIn2 can be conﬁgured as single-ended input (Table 14.8 lists the

available standards). Fig. 14.5 shows two examples, how a single-ended conﬁgured input can

be used.

The inputs must be driven by a push-pull stage or an open drain output with a

pull-up resistor.
