Deltapilot S FMB70 Operation
Endress+Hauser 27
5 Operation
5.1 Device behavior during power-up
Once switched on, the device runs through a diagnostic phase of approx. 30 s. During this
time, the current output is first set to approx. 12 mA, then to 4 mA, before the current
that is output actually corresponds to the current measured value. Communication via
HART is not possible during the diagnostic phase.
5.2 Behavior of device in the event of an alarm and
warnings
The output current on alarm can be set to a value of ≤ 3.6 mA or ≥ 21 mA.
L
CAUTION
In some cases, (e.g. failure of power supply, a cable open circuit and faults in the
current output itself, where the error current ≥ 21 mA cannot be reached), output
currents ≤ 3.6 mA occur irrespective of the configured failure current. In some other
cases, (e.g. cabling short circuit), output currents ≥ 21.0 mA occur irrespective of the
configured failure current.
‣
For alarm monitoring, the downstream logic unit must be able to recognize failure
currents of the upper level for signal on alarm (≥ 21 mA) and the lower level for signal
on alarm (≤ 3.6 mA).
