Cerabar S/Deltabar S/Deltapilot S 4...20mA HART
Description of parameters
Hauser
113
ALT. CURR. OUTPUT (597)
Selection
Set current output if sensor limits undershot or overshot.
Options:
• Normal: the current output assumes the value set via the OUTPUT FAIL MODE and
SET MAX. ALARM parameters.
• Special:
– Lower sensor limit undershot (E120):
Current output = 3.6 mA
– Upper sensor limit overshot (E115): current output assumes the value set via the
SET MAX. ALARM parameter.
Attention : when using the case "special", the behavior is limited to an over/
underpressure in a range LRL -10%, URL +10%.
Factory setting:
Normal
SET MAX. ALARM (342)
Entry
Enter current value for maximum alarm current.
See also OUTPUT FAIL MODE.
Input range:
21...23 mA
Factory setting:
22 mA
SET MIN. CURRENT (343)
Entry
Enter lower current limit.
Some switching units sometimes do not accept currents less than 4.0 mA.
Options:
• 3.8 mA
• 4.0 mA
Factory setting:
3.8 mA
ASSIGN CURRENT (760)
Selection
Specify current signal for the "Level" measuring mode.
See also SET LRV (
Page 98) and SET URV (
Page 98).
Prerequisite:
• MEASURING MODE = Level, LEVEL MODE = Height Linearized
Options:
• Height
• Tank content
Factory setting:
Tank content
LINEAR/SQROOT (390)
Selection
Specify current signal for the "Flow" measuring mode.
See also SET LRV (
Page 99) and SET URV (
Page 100).
Prerequisite:
• MEASURING MODE = Flow
Options:
• Differential pres.: the linear pressure signal is used for the current output.
• Flow (square root): the root flow signal is used for the current output. The "Flow
(square root)" current signal is indicated on the on-site display with a root symbol.
Factory setting:
Flow (square root)
