Fault acknowledge (0 Î 1)
The fault signal is acknowledged with a positive edge; the sensor reaction to a fault depends on the type of fault.

1 Fault present
Unacknowledged faults or currently not acknowledged faults (fault messages) are present (in the buffer).
The fault reaction is fault-specific and device-specific. The acknowledging of a fault may only be successful,
if the fault cause has disappeared or has been removed before. If the fault has been removed the sensor returns
to operation. The related fault numbers are in the fault buffer.
0 No fault

1 Control request The automation system is requested to assume control.
0 No control request Control by automation system is not possible, only possible at the device or by another interface.

13 Transmit absolute value cyclically
If bit 13 transmits absolute value cyclically or bit 15 sensor error is not set there is no valid value or error code
transferred in G1_XIST2.
Bit 13 transmits absolute value cyclically cannot be set at the same time as bit 15 sensor error. These bits are used
to indicate either a valid position value transmission (bit 13) or the error code transmission (bit 15) in G1_XIST2.

14 Activate parking sensor
If the sensor parking is activated (bit 14 = 1) the sensor is still on the bus with the slave sign-of-life active and
the sensor error and diagnostics switched off.
