5.7.2.3 Time delayed message for output OFF
If an input changes from HIGH to LOW, i.e. there is no longer an input signal, a delayed message can also be
activated here. The SMS relay sends the predefined message after the preset time has elapsed and if the
signal is no longer present respectively the input signal was constantly OFF during the selected time delay.
Time delays of 0.1 seconds to 99.9 hours are possible. This time function must be activated and is to prevent
that unstable short signals as for example of a floating level switch will activate numerous messages.
REMARK
It is recommended to use the delay function to avoid that several messages being sent for the
same event.
5.7.3 Analogue inputs
The 4 inputs(AI1—AI4) can be individually configured as digital or analogue inputs. For that purpose
each input has to be predefined as analogue or digital input. The analogue inputs(AI1-AI4) are
designed for a standard 0 … 10V DC ,AI5 and AI6 are designed for a standard 0 … 20 mA analogue signal.
5.7.3.1 Scaling and units
In a first step, the measuring unit and the scale have to be defined. For both end-values 0V (0 mA) and 10V
