ON-VALUE
!
(4242)
This function is not available unless STATUS was selected in the function OPERATION
MODE (4200) and LIMIT VALUE or FLOW DIRECTION was selected in the function
ASSIGN STATUS (4241).
Use this function to assign a value to the switch-on point (activation of the status output).
The value can be equal to, greater than or less than the switch-off point. Positive or nega-
tive values are permissible, depending on the measured variable in question (e.g. volume
flow, totalizer reading).
User input:
5-digit floating-point number, [unit]
Factory setting:
0 [unit]
!
• The appropriate unit is taken from the function UNIT VOLUME FLOW (0402).
• Only the switch-on point is available for flow direction output (no switch-off point).
SWITCH-ON DELAY
!
(4243)
This function is not available unless STATUS was selected in the function OPERATION
MODE (4200) and LIMIT VALUE or FLOW DIRECTION was selected in the function
ASSIGN STATUS (4241).
Use this function to specify a delay (0...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 sta-
tus 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...100.0 s
Factory setting:
0.0 s

Note!
Note!
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.
