For Intrinsically Safe applications: read chapter 5.
The following terminal connectors are available:
Fig. 9: Overview of terminal connectors F012-P-(PF / PM) and options.
SENSOR SUPPLY
Type PF-PM: Sensor supply: 1.2, 3.2V, 8.2V, 12V or 24 V:
With this option, a real power supply for the sensor is available. The flowmeter can be powered with
1.2, 3.2, 8.2, 12 or 24 V DC (max. 400mA@24V). The voltage is selected with the three switches
inside the enclosure.
Warning: be sure that all the leads to the terminals are disconnected from the unit when
the internal plastic protection cover has been removed !
HIGH VOLTAGE 400V !! NEVER connect the mains power supply to the unit when the
plastic protection cover has been removed !!!
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:
Fig. 10: switch position voltage selection (type PF and PM).
