15.4 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.
The max. flow that the pulse output can work with will be displayed now. This value is calculated on the basis of the en-
tered pulse value and pulse width.
If the flow exceeds this value, the pulse output will not function properly. In this case, the pulse value and the pulse width
have to be adapted to the flow conditions.Press ENTER.
15.5 Activation of a Binary Output as an Alarm Output
15.5.1 Alarm Properties
The switching condition, the holding behavior and the switching function of an alarm output can be defined.
Press key to select a scroll list in the upper line. Press key to select a list item in the lower line.
Press ENTER to store the settings.
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 program branch
Output Options
. Press ENTER until
Pulse Output
is dis-
played.
Select
yes
to activate the output. Press ENTER.
This error message will be displayed if the flow velocity has been selected as the physical
quantity.
The use of the pulse output is not possible in this case because integrating the flow velocity
does not result in a reasonable value.
Enter the pulse value. The unit of measurement will be displayed according to the current
physical quantity.
When the totalized physical quantity reaches the pulse value, a pulse will be emitted.
Enter the pulse width.
The range of possible pulse widths depends on the specification of the measuring instru-
ment (e.g., counter, PLC) that is to be connected to the output.
Note! The menu item
Alarm Output
will only be displayed in the program branch
Output Options
if an
alarm output has been installed.
Select the program branch
Output Options
. Press ENTER until
Alarm Output
is dis-
played.
Select
