OFF-VALUE
MODBUS register:
Data type:
Access:
4244
3241
Float
read/write
! Note!
Function is not available unless STATUS was selected in the OPERATION MODE
function (4200) and a 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 higher or lower than the switch-on point.
Positive and negative values are permissible, depending on the measured variable
in question (e.g. mass flow, totalizer reading).
User input: 5-digit floating-point number, [unit]
Factory setting: 0 [kg/h] or 2 [kg/l] or 200 [°C]
! Note!
• The appropriate unit is taken from the function UNIT VOLUME FLOW (0402)
or UNIT MASS FLOW (0400).
• If SYMMETRY is selected in the function MEASURING MODE (4246) and
values with different signs are entered for the switch-on and switch-off points,
the notice message “INPUT RANGE EXCEEDED” appears.
SWITCH-OFF
DELAY
MODBUS register:
Data type:
Access:
4245
3243
Float
read/write
Volatile
! Note!
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 the switch-off (i.e. signal
changes from “conductive” to “not conductive”) of the status output. The delay
starts when the limit value is reached. The status output does switch when the
delay has timed out and the switch off condition has been valid over the delay
time.
User input: fixed-point number: 0.0 to 100.0 s
Factory setting: 0.0 s
