Note!
The following applies to both configuration methods "Increased security during parameter entry" and "Standard
device configuration":
– During device configuration, the selected current value in the event of a fault cannot be guaranteed for all
possible fault situations (e.g. cable open circuit). However, failure reaction in accordance with NE 43
(
≤
3.6 mA or
≥
21 mA) is always ensured.
– The current value can be (independent of the selected current value) between 22 and 25 mA when the
integrated diagnostics and monitoring measures are triggered.
– In cases such as power failure or circuit break, output currents can be (independent of the selected current
value)
≤
3.6 mA.
– After an error or a fault has been removed, the 4...20 mA output signal can be considered to be safe after
20 seconds.
– For the maximum reaction time of alarms and warnings

Total performance "Total performance" comprises non-linearity including hysteresis and non-repeatability, the thermal change of
the zero point:
±1 % of the URL (upper range limit)
The information applies to a temperature range from –10...+60 °C (+14...+140°F).
Settling time The settling time is calculated according to the following formula:
t
settling time
= t
1
+ (t
2
+ configured damping time) x 5
For t
1
(dead time) and t
2
(T63)

Technical Information TI416P, "Dead time, time constant (T63)" section.
The factory setting for the damping time is 2 seconds, but can be configured between 0 and 999 seconds.
In accordance with IEC 61298-2, the settling time is the time the output signal needs to reach its steady-state
value at 1% of the output span and remain within this range.
Maximum reaction time of
alarms and warnings The reaction times of alarms and warnings are listed in the following table. In the event of an alarm (device
faults), the device outputs an error current,
