Technical Instructions forCorrelation SensorsPage 48 Correlation Sensors – Rev. 07 as of 20.04.2016®1 cable jacket2 shrunk-on hose3 black; cable shield (no ground)4 red; power supply +; max. 10,5V5 blue; power supply -6 white; RxTx +7 green; RxTx -Fig. 5-25 Cable end configuration; Electronic Box5.7 Cable extensionWARNING Electrical connectionCable extension and sensor connection should be accomplished by author-ised expert staff only.WARNING Possible electrical interferenceIf you wish to extend cables by using a terminal box use a box made of metal.The shields of outgoing as well as incoming cables must be wired to theground connection of the terminal box.Inappropriate connections leading to increased contact resistance or the useof unsuitable cables may result in interferences or even measurement fail-ures.Sensors with integrated pressure cell and sensor connection type „L“ (see Fig.2-12) are equipped with a specially prepared cable type LIY11Y 2x1.5 mm² +1x2x0.34 mm² + PA 1,5/2,5. Sensors without pressure measurement cell as wellas the external Electronic Box with sensor connection type "K" are equipped withcables type LIY11Y 2x1.5 mm² + 1x2x0.34 mm². These cables can be extendedwithout any problem by using single shielded signal cables.Sensors with integrated pressure cell and sensor connection types "F" or "S"are equipped with the respectively wired plugs; type „F“ are equipped with anadditional air filter with a dehydration agent on the connection plug (see Fig.5-26). These sensors cannot be extended.
