Solicap M FTI55, FTI56 Technical data
Endress+Hauser 81
10 Technical data
10.1 Input
10.1.1 Measured variable
Level limit detection of change in capacitance between probe rod and container wall or ground tube,
depending on the level of a liquid.
10.1.2 Measuring range (valid for all FEI5x)
• Measuring frequency:
500 kHz
•Span:
C = 5 to 1600 pF
C = 5 to 500 pF (with FEI58)
• Final capacitance:
C
E
= max. 1600 pF
• Adjustable initial capacitance:
C
A
= 5 to 500 pF (range 1 = factory setting)
C
A
= 5 to 1600 pF (range 2; not with FEI58)
10.1.3 Input signal
Probe covered => high capacitance
Probe not covered => low capacitance
10.2 Output
10.2.1 Galvanic isolation
FEI51, FEI52
between rod probe and power supply
FEI54
between rod probe, power supply and load
FEI53, FEI55, FEI57S, FEI58
see connected switching device (functional galvanic isolation in the electronic insert)
10.2.2 Switch behavior
Binary or s mode (controlling a screw conveyor, not with FEI58)
10.2.3 Switch-on behavior
When the power supply is switched on, the switching status of the outputs corresponds to the signal
on alarm. The correct switch condition is reached after max. 3 seconds.
10.2.4 Failsafe mode
Minimum/maximum quiescent current safety can be switched at the electronic insert (for FEI53
and FEI57S only at Nivotester FTCxxx)
MIN = minimum safety: The output switches safety-oriented when the probe is uncovered
(signal on alarm). For use for dry running protection and pump protection for example
