ON-VALUE Use this function to assign a value to the switch-on point (status output conductive). The
value can be greater or less than the switch-off point. Negative values are only permitted
for the measured variable TEMPERATURE.
! Note!
This function is not available unless the STATUS setting was selected in the OPERATION
MODE function and LIMIT VALUE was selected in the ASSIGN STATUS function.
User input:

/h] or 0 [°C]/+32 [°F]
(country dependent, → Page 71 ff.)
! Note!
The appropriate unit is taken from the group SYSTEM UNITS (see Page 9)
OFF-VALUE Use this function to assign a value to the switch-off point (deactivation of the status out-
put). The value can be greater or less than the switch-on point. Negative values are only
permitted for the measured variable TEMPERATURE.
! Note!
This function is not available unless the STATUS setting was selected in the OPERATION
MODE function and LIMIT VALUE was selected in the ASSIGN STATUS function.

TIME CONSTANT Use this function to enter a time constant defining how the measurung signal reacts to
severely fluctuating measured variables, either very quickly (enter a low time constant) or
with damping (enter a high time constant). Damping acts on the measuring signal before
the switch status changes, and consequently before switch-on or switch-off delay is acti-
vated. The purpose of damping, therefore, is to prevent the status output changing state
continuously in response to fluctuations in flow.
! Note!
This function is not available unless one of the following was selected in the ASSIGN
STATUS function:
• LIMIT MASS FLOW
• LIMIT CORRECTED VOLUME FLOW
• LIMIT TEMPERATURE
User input:
fixed-point number: 0.0 to 100.0 s
Factory setting:
0.0 s
ACTUAL STATUS Use this function to check the current status of the status output.
! Note!
This function is not available unless the STATUS setting was selected in the OPERATION
MODE function.
