OUTPUT SIGNAL
!
Note!
This function is not available unless the PULSE setting was selected in the OPERATING
MODE function.
Use this function to configure the output in such a way that it matches an external
counter, for example. Depending on the application, you can select the direction of the
pulses here.
Options
:
PASSIVE - POSITIVE
PASSIVE - NEGATIVE
Factory setting
:
PASSIVE - NEGATIVE
ASSIGN STATUS
OUTPUT
!
Note!
This function is not available unless the STATUS setting was selected in the OPERATING
MODE function.
Configuration of the status output.
Options
:
ON (operation)
ALARM
NOTICE MESSAGE
ALARM or NOTICE MESSAGE
FLOW DIRECTION
VOLUME FLOW LIMIT VALUE
Factory setting
:
ALARM
!
Note!
• The behavior of the status output is a normally closed behavior, 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
91.
SWITCH-ON POINT
!
Note!
This function is not available unless LIMIT VALUE or FLOW DIRECTION was selected in
the ASSIGN STATUS OUTPUT 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 permissible.
User input
:
5-digit floating-point number, [unit]
Factory setting
:
0 [unit]
!
Note!
• The appropriate unit is taken from the SYSTEM UNITS group.
• 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.
