9.7.3 Setting the switching limits (window function)
u
Make sure that for [OU1] the function [Fno] or [Fnc] is set.
u
Select [FH1] and set the upper limit of the acceptable range.
[FH1]
u
Select [FL1] and set the lower limit of the acceptable range.
FL1 is always lower than FH1. The device only accepts values which are lower than the value for
FH1.
[FL1]
9.7.4 Setting the switch-off delay for OUT1
u
Select [dr1] 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 (OU1 = Hno or
Hnc).
[dr1]
9.7.5 Setting the output function for OUT2
u
Select [OU2] and set the output function:
[OU2]
[I] = current output 4… 20 mA
[InEG] = current output 20… 4 mA
[U] = voltage output 0… 10 V
[UnEG] = voltage output 10… 0 V
9.7.6 Setting the switching logic for the output
u
Select [P-n] and set [PnP] or [nPn].
[P-n]
9.7.7 Scaling the analogue signal
u
Select [ASP2] and set the analogue start point.
u
Select [AEP2] and set the analogue end point.
[ASP2]
[AEP2]
9.7.8 Setting response of the outputs in case of a fault
u
Select [FOU1] / [FOU2] and set the value:
• [on] = switching output switches ON in case of a fault.
Analogue output switches on 20 mA / 10 V in case of a fault.
• [OFF] = switching output switches OFF in case of a fault.
Analogue output switches on 4 mA / 0 V in case of a fault.
Factory setting: [FOU1] and [FOU2] = [OFF].
Faults: faulty hardware, too low a signal quality, untypical level curve. Overflow is not considered to be
a fault!
[FOU1]
[FOU2]
9.7.9 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.
