SENSOR SUPPLY
Type PF-PM: Sensor supply: 8.2V, 12V or 24 V:
With this option, a real power supply for the sensor is available. The sensor can be powered with
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 (option PF / PM) as indicated:
