Description of Device Parameters Deltabar FMD71, FMD72
94 Endress+Hauser
Description Set current output if sensor module limits are exceeded or not reached.
Options • Warning
The device continues to measure. An error message is displayed.
• Alarm
The output signal assumes a value that can be defined by the "Output fail mode (190)/
(051)" function.
• Special
– The lower sensor module limit is undershot (sensor module LP or HP or complete
system):
Current output = 3.6 mA
– The upper sensor module limit is overshot (sensor module LP or HP or complete
system):
Current output assumes a value of 21 - 23 mA, depending on the setting of the "High
alarm curr." (052) parameter.
Factory setting Warning
Alarm cur. switch (165)
Navigation Setup → Extended setup → Current output → Alarm cur.switch (165)
Write permission No write permissions. Parameter is read only.
