Hauser 101
ASSIGN STATUS
!
Note!
This function is not available unless the STATUS setting was selected in the
OPERATION MODE function (Page 99).
Options:
ON (operation)
FAULT MESSAGE
NOTICE MESSAGE
FAULT & NOTICE MESSAGE
EPD (Empty Pipe Detection, only if active)
FLOW DIRECTION
VOLUME FLOW LIMIT VALUE
Factory setting:
FAULT MESSAGE
!
Note!
• The behaviour of the status output is a normally closed behaviour, in other
words the output is closed (transistor conductive) when normal, error-free
measuring is in progress.
• It is very important to read and comply with the information on the switching
characteristics of the status output (see Page 103).
ON-VALUE
!
Note!
This function is not available unless LIMIT VALUE or FLOW DIRECTION was
selected in the ASSIGN STATUS function.
Use this function to assign a value to the switch-on point (status output pulls
up). The value can be equal to, greater than or less than the switch-off point.
Positive and negative values are permitted.
User input:
5-digit floating-point number, [unit]
Factory setting:
0 [unit]
!
Note!
• The appropriate unit is taken from the SYSTEM UNITS group (see Page 93).
• Only the switch-on point is available for flow direction output (no switch-off
point). If you enter a value not equal to the zero flow (e.g. 5 ), the difference
between the zero flow and the value entered corresponds to half the
switchover hysteresis.
OFF-VALUE
!
Note!
This function is not available unless LIMIT VALUE was selected in the ASSIGN
STATUS function.
Use this function to assign a value to the switch-off point (status output drops
out). The value can be equal to, greater than or less than the switch-on point.
Positive and negative values are permitted.
User input:
5-digit floating-point number, [unit]
Factory setting:
0 [unit]
!
Note!
• The appropriate unit is taken from the SYSTEM UNITS group (see Page 93).
• If SYMMETRY is selected in the MEASURING MODE function (Page 108)
and values with different signs are entered for the switch-on and switch-off
points, the notice message “INPUT RANGE EXCEEDED” appears.
