17.4 Configuration of a frequency output as a pulse output
A frequency output sends a signal with a frequency that depends on the volume flow rate. The frequency output can be
configured in such way that the source item can be totalized by using each period of the output signal as the increment.
17.4.1 Installation of a frequency output (optional)
17.4.2 Activation of the output
17.5 Activation of a binary output as a pulse output
A pulse output is an integrating output which emits a pulse when the volume or the mass of the fluid which has passed the
measuring point reaches a given value (Pulse Value). The integrated quantity is the selected physical quantity. Integra-
tion is restarted as soon as a pulse is emitted.
Select Frequency F1 in Special Funct.\SYSTEM settings\Proc. outputs.
Press ENTER.
Select yes if the output has not been installed. Press ENTER.
or
Select no if the output has already been installed. Press ENTER.
Select the measuring channel to be assigned to the output as the source channel in the
scroll list. Press ENTER.
Select in the scroll list Measuring value (but not Impuls!). Press ENTER.
If Measuring value has been selected and the source item can be totalized, a request
will be indicated whether the frequency output is to be configured as a pulse output. Select
yes. Press ENTER.
Enter the upper limit of the frequency. Press ENTER.
The lower limit of the frequency and the error value will be set automatically to 0.5 Hz.
Select the channel for which the input is to be activated in the program branch Output
Options. Press ENTER.
This display will not be indicated if the transmitter has only one measuring channel.
Select yes to activate the output. Press ENTER.
Enter the number of pulses that is to be assigned to the unit of measurement of the totaliz-
er. Press ENTER.
example: 1000 pulses correspond to 1 m³ of the totalized fluid.
The max. flow depending on the upper limit of the frequency and pulse value is indicated.
Press ENTER.
Note! The menu item Pulse Output will only be indicated in the program branch Output Options if a
pulse output has been installed.
Select the channel for which a pulse output is be activated in the program branch Output
Options. Press ENTER.
This display will not be indicated if the transmitter has only one measuring channel.
