8、 valve is controlled in the Manual mode the valve can move quickly Incorrect settings can cause self oscillation which can lead to damage Important Always turn off the compressed air supply before removing or disconnecting the air supply connection or the integral filter Remove or disconnect with ca
9、re because C is still under pressure even after the air supply is turned off Always work in an ESD protected area when servicing the PCB s Make sure the input signal is switched off The air supply must be free from moisture water oil and particles The modules can be factory assembled before delivery
10、 or fitted later The modules for feedback and limit switches can contain the following Feedback 4 20 mA and one of the following functions Two mechanical contacts Two reed switches Two inductive sensors DIN 19234 4 2 Storage General The PMV positioner is a precision in strument Therefore it is essen
11、tial that it is handled and stored in the right way Always follow the instructions below N B As soon as the positioner is connected and started internal air leakage will provide protection against corrosion and prevent the ingress of moisture For this reason the air supply pressure should always be
12、kept on Storage indoors Store the positioner in its original packaging The storage environment must be clean dry and cool 15 to 26 C 59 to 79 F Storage outdoors or for a longer period If the positioner must be stored outdoors it is important that all the cover screws are tightened and that all conne
13、ctions are properly sealed The unit should be packed with a desiccant silica gel in a plastic bag or similar covered with plastic and not exposed to sunlight rain or snow This is also applicable for long term storage more than 1 month and for long transport by sea Storage in a warm place When the po
14、sitioner is stored in a warm place with a high relative humidity and is subjected to daily temperature variations the air inside the unit will expand and contract This means that air from outside the unit may be drawn into the positioner Depending on the temperature variations relative humidity and
15、other factors condensation and corrosion can occur inside the unit which in turn can give rise to functional disorders or a failure 5 3 Design Filter Display control push buttons Positional feedbackProcessor and motherboard Terminal block Adjusting screws damping Valve block The D3 positioner contai
