9.7.4 Setting the switch-off delay
u
Select [dr1]…[dr4] and set the value between 0.2 and 60 s.
At 0.0 (= factory setting) the delay time is not active.
The switch-off delay is only active if hysteresis has been set as switching function (OUx = Hno or
Hnc).

9.7.5 Setting the switching logic for the outputs
u
Select [P-n] and set [PnP] or [nPn].
[P-n]
9.7.6 Setting response of the outputs in case of a fault
u
Select [FOU1]…[FOU4] and set the value:
• [on] = switching output switches ON in case of a fault.
• [OFF] = switching output switches OFF in case of a fault.
Factory setting: [FOU1]…[FOU4] = [OFF].
Faults: faulty hardware, too low a signal quality, untypical level curve. Overflow is not considered to be
a fault!

[FOU4]
9.7.7 Setting the delay time after signal loss
u
Select [dFo] and set a value between 0.2 and 5.0 s.
At 0.0 (= factory setting) the delay time is not active.
Mind the dynamics of your application. In case of fast level changes it is recommended to adapt the
value step by step.

9.8 Resetting all parameters to factory setting
u
Select [rES], then press [Set] and keep it pressed until [----] is displayed.
u
Briefly press [Mode/Enter].
w
The device reboots and then the factory settings are restored.
Note: on delivery the device is not operational. First, the basic settings must be entered.

9.9 Changing basic settings
Changing the basic settings is required after changes to the probe or to the application area.
9.9.1 Re-entering probe length
u
Change to menu level 2
u
Select [LEnG] and set probe length L. Step increment: 0.5 cm
Remarks on the determination of the probe length
:
u
Observe the notes on single probes or coaxial probes.
u
Briefly press [Mode/Enter].
Note: after changing the probe length, the values for OFS and the switching limits must also be re-
viewed / re-entered.
