Step Programming
5 Setting of the switching parameters
SP1: setpoint 1 = upper limit value at which the switch-
ing output OUT1 changes its switching status.
rP1: reset point 1 = lower limit value at which the switch-
ing output OUT1 changes its switching status.
OU1: switching function for the switching output OU1.
4 settings can be selected: hysteresis (H..) or win-
dow function (F..)as normally open (.no) or normal-
ly closed (.nc).
SP2: setpoint 2 = upper limit value at which the switch-
ing output OUT2 changes its switching status.
rP2: reset point 2 = lower limit value at which the switch-
ing output OUT2 changes its switching status.
OU2: switching function for the switching output OU2.
4 settings can be selected: hysteresis (H..) or win-
dow function (F..)as normally open (.no) or normal-
ly closed (.nc).
Setting ranges for SPx and rPx → page 38.
Note: If the upper setpoint is used as an overflow pro-
tection, the setting OUx = Hnc (nc function) is recom-
mended. The principle of normally closed operation
ensures that wire break or cable break is also detected
6 Setting of the switch-off delay
dr1: switch-off delay for the switching output OUT1
dr2: switch-off delay for the switching output OUT2
• Setting range: 0...5 s in steps of 0.2 s.
The switch-off delay is only effective when setting the
switching function hysteresis (OUx = H..).
7 Response of the outputs in case of a fault
FOU1: Wrong response for the switching output OUT1
FOU2: Wrong response for the switching output OUT2
2 settings can be selected:
• On = output switches ON in case of a fault.
• OFF = output switches OFF in case of a fault.
Factory setting: FOU1 / FOU2 = OFF.
Faults are: faulty hardware, too low a signal quality.
Overflow is not considered to be a fault!
