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.
It is required to link the minus from the analog output - terminal 7 - with a ground terminal of
the unit; terminal: 00, 03, 05, 09, 12 or 15.

For type PD-XI:
It is possible to supply the sensor with different voltages. You can set the voltage
with the switches. Internal power is only applicable for low power sensors (Coil, Reed). The sensor
supply is set by the firmware: 1.2V DC or 3V DC. 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 F116-P safe. If applicable, mind the battery power.
2. Open the F116-P 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 F116-P.
Risk of electrocution - High voltage!
Make sure, all the leads to the terminals are disconnected from the F116-P and NEVER
connect the mains power supply to the unit when the protection cover has been removed!
