NOTE
Error recognition
Error recognition can be selected only with 4 ... 20 mA signal of the process value.
Error is recognized with an input signal
≤ 3.5 mA (±0.5 % of end value, hysteresis 0.5 %
of end value).
With signal error recognition activated: PV FAULT signal error of process controller value.
With the process controller deactivated,
NOT.AVAIL appears in the selection menu.
