Explanation Intrinsically safe options:
Type AF - Intrinsically safe floating 4-20mA analog output - Terminal 7-8:
A floating 4-20mA signal proportional to the flow rate is available with this option. When the output is
disabled, a 3.5mA signal will be generated. Max. driving capacity 1000 Ohm @ 30V DC.

For option PD-XI:
It is possible to supply the sensor with different voltages. You can set the voltage
with the switches. Internal power is not suitable for analog sensors. External power is only available
when the main external power supply is connected. The sensor supply voltage is fixed: 8.2V DC.
Set the sensor supply
1. Make the F113-A safe. If applicable, mind the battery power.
2. Open the F113-A and carefully remove the cable-connectors and the protective cover.
3. Find and set the switches and select the V
out
as required.
4. Close the protective cover and install the cable connectors.
5. Close the F113-A .
Risk of electrocution - High voltage!
Make sure, all the leads to the terminals are disconnected from the F113-A and NEVER
connect the mains power supply to the unit when the protection cover has been removed!
