POWER SUPPLY WIRING
When not directly supplied from mains (type PM), the external power supply must be an
approved ELV source, insulated from AC mains by double / reinforced insulation per CSA
C22.2 No. 61010-1 / UL61010-1 / EN/IEC 61010-1.
The F010-A can be powered from an external power supply. An internal power supply is also
available in the form of a lithium battery. When both external and internal power supplies are
available, the internal power supply is interrupted and will act as a backup supply. Note that the
optional backlight only works with an external power supply.

SENSOR SUPPLY
For type PD - Terminal 6: sensor supply
Type PD offers a sensor supply on terminal 6, with the same voltage as the supply connected to
terminal 5.
For type PF / PM
– Terminal 7: sensor supply, 8.2V, 12V or 24V
Type PF and PM offer a power supply for the sensor. The flowmeter can be externally powered with
8.2V, 12V or 24V DC (max. 400mA@24V). The voltage is selected with the three switches inside the
F010-A.
•
Be sure that all the leads to the terminals are disconnected from the F010-A when the
internal plastic protection cover has been removed !
•
HIGH VOLTAGE 400V !!
NEVER connect the mains power supply to the F010-A when the plastic protection cover
has been removed !!!
To gain access to the switches, first remove the terminal strip(s) after which the internal plastic cover
can be removed. The switches are located on the right hand side as indicated:
