3.3 Profibus Cable Connection If no Profibus cable is available, make one according to the following indications: 1 5 6 9 Pin 1 Do not connect Pin 2 Do not connect Pin 3 RxD/TxD-P Pin 4 CNTR-P 4) Pin 5 DGND 5) Pin 6 VP 5) Pin 7 Do not connect Pin 8 RxD/TxD-N Pin 9 Do not connect D-Sub, 9-pin, male, soldering side Connect the Profibus cable to the gauge and secure the cable socket to the gauge with the lock screws. 4) 5) Only to be connected if an optical link module is used. Only required as line termination for devices at the ends of bus system (→ [5]). 22 tqma03e1 (2010-05)
4 Operation When the supply voltage is applied, the measurement signal is available between pins 2 (+) and 12 (–) (relationship between measurement signal and pressure → 14 and [1]). The Profibus gauge can also be operated via the corresponding fieldbus interface (Profibus) (→ [1] for details and further functions). Allow for a stabilizing time of ≈10 minutes. Once the gauge has been switched on, permanently leave it on irrespective of the pressure. 4.1 Gas Type Dependence The measurement value is gas type dependent. The pressure reading applies to dry air, O 2 , CO and N 2 . For other gases, it has to be converted (→ 15 and [1]). tqma03e1 (2010-05) 23
