4.9 Description of the outputs
4.9.1 Current output
• All outputs are electrically isolated from each other and from all other circuits.
• All operating data and functions can be adjusted.
• Passive mode: external power U
ext
≤ 32 VDC at I ≤ 22 mA
• Active mode: load impedance R
L
≤ 750 Ω at I ≤ 22 mA
• Self-monitoring: interruption or load impedance too high in the current output loop
• Error message possible via status output, error indication on LC display.
• Current value error detection can be adjusted.
• Automatic range conversion via threshold. The setting range for the threshold is between 5
and 80% of Q
100%
, ± 0...5% hysteresis (corresponding ratio from smaller to larger range of
1:20 to 1:1.25).
Signaling of the active range possible via a status output (adjustable).
• Forward / reverse flow measurement (F/R mode) is possible.
INFORMATION!
Depending on the version, the outputs must be connected passively or actively!
