7 Block OUTPUTS Device Functions Proline Promass 83
Function description
OUTPUTS PULSE/FREQUENCY OUTPUT (1...2) CONFIGURATION (STATUS)
OFF-VALUE
(4244) ! Note!
This 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
(4245) ! Note!
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...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...100.0 s
Factory setting:
0.0 s
