(4243)
This function is not available unless STATUS was selected in the OPERATION MODE
function (4200) and LIMIT VALUE or FLOW DIRECTION was selected in the
ASSIGN STATUS function (4241).
Use this function to specify a delay (0 to 100 seconds) for switching on the status output
(i.e. signal changes from 0 to 1). The delay starts when the limit value is reached. The
status output does switch when the delay has timed out and the switch-on condition has
been valid over the delay time.
User input:
fixed point number: 0.0 to 100.0 s
Factory setting:

(4244)
This function is not available unless STATUS was selected in the OPERATION MODE
function (4200) and LIMIT VALUE was selected in the ASSIGN STATUS function
(4241).
Use this function to assign a value to the switch-off point (deactivation of the status
output). The value can be equal to, greater than or less than the switch-on point. Positive
and negative values are permissible, depending on the measured variable in question
(e.g. volume flow).
User input:
5-digit floating-point number, [unit]
Factory setting:
0 [unit]

• The appropriate unit is taken from the UNIT VOLUME FLOW function (0402) .

SWITCH-OFF DELAY
!
(4245)
This function is not available unless the STATUS setting was selected in the
OPERATION MODE function (4200).
Use this function to define a delay (0 to 100 seconds) for switching off the status output
(i.e. signal changes from 1 to 0). The delay starts when the limit value is reached. The
status output does switch when the delay has timed out and the switch condition has
been valid over the delay time.
User input:
Fixed point number 0.0 to 100.0 s
Factory setting:
0.0 s
