
Analogue outputs.
The options available in the standard program can also be used for the pump program, and
additionally the option ‟20 CURRENT FLOW‟, that can be configured to provide the read flow
at any of the analogue output formats.
o
Example 1 for configuring the analogue output as read flow.
In case the flowmeter data configured in G4.4 are:
Units: litres
Pulses / second: 100l/s
Maximum Range: 1000 litres
Analogue output setting:
Format: 0
– 10V
Minimum Range: 0
Maximum Range: 100%
For a read flow of 500 litres, the analogue output will be:
o
Example 2 for configuring the analogue output as read flow.
If the flowmeter data configured in G4.4 are:
Units: litres
Pulses / second: 100l/s
Maximum Range: 1000 litres
Analogue output setting:
Format: 4
– 20mA
Minimum Range: 0
Maximum Range: 100%
For a read flow of 500 litres, the analogue output is:
Additionally, it exists the option 27, that it is not directly settable by the user for any of the
analogue outputs. On the contrary, this option is automatically set for the program to the
Analogue Output 1 in case of the user enables the Fixed Pump 4, and it will be
automatically set for the Analogue Output 2 when the user enables the Fixed Pump 5. For
both outputs, the format configuration will always be 0 to 10V, where 0 means the Pump is
OFF and 10V means the Pump is ON.
