If the manufacturer makes a modification that has an effect on the safety function of the device,
the manufacturer will tell you about the modification immediately.

±3 µA
Low: ≤ 3.6 mA acc. to NAMUR NE 43
High: ≥ 21 mA acc. to NAMUR NE 43
If an error is >2.5% of the output signal, this error has a "dangerous undetected
failure" status.
HART® protocol via passive current output
Yes. Current output = 4 mA. HART® Address = 0. Output current data that is
transmitted in less than 1 ms is ignored (this data filter agrees with HART® protocol
requirements).
Multidrop operation is not permitted because the current output (safety function)
must be set to 4 mA. Thus, the safety function cannot supply data about the device
status.
Not yet available. This option is not permitted.

Response time = value given in supervisor menu item 2.4.5 ERROR DELAY
If electrical power is not sufficient for correct operation of the device (worst
conditions for operation), the error is shown in less than 30 seconds.
1 time / day (firmware does an auto-diagnostic test)
