Installation...5 Electrical connection Scale drawing Technical data...8 Safety instructions Please read the product description prior to installing the unit. Please check that the product is suitable for your application without any restrictions. If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur. Please check in all applications that the product materials (see Technical data) are compatible with the media to be measured. For gaseous media the application is limited to max. 6 PSI. High-pressure units (5000 PSI) are supplied with a pressure relief mechanism and an integrated damping device to comply with the regulations for UL approval and to avoid any risk of injury in case of bursting when bursting pressure is exceeded. Any manipulation of the damping device is not permissible. When the damping device is removed, there is no damping function any more. ATTENTION: risk of injury! For units with culus approval this approval becomes invalid when the damping device is removed.

3 For units with culus approval and the scope of validity culus: The device shall be supplied from an isolating transformer having a secondary Listed fuse rated as noted in the following table. Overcurrent protection Control-circuit wire size Maximum protective device rating AWG (mm ) Ampere 6 (0.) (0.0) (0.) 0 (0.5) 5 8 (0.8) 7 6 (.) 0 The Sensor shall be connected only by using any R/C (CYJV) cord, having suitable ratings.

4 Function and features The pressure sensor detects the system pressure and converts it into an analog output signal. 0 to 0 V (PX9xxx) 0 to 0 V (PX99) to 0 ma (PXxxx) 0 to ma (PX9) Applications (type of pressure: relative pressure) Order no.

5 Avoid static and dynamic overpressure exceeding the given over-load pressure. Even if the bursting pressure is exceeded only for a short time the unit can be destroyed (danger of injuries)! Installation Before mounting and removing the sensor, make sure that no pressure is applied to the system. Mount the pressure sensor on a suitable process connection (see type label Port Size ). Electrical connection The unit must be connected by a qualified electrician. The national and international regulations for the installation of electrical equipment must be adhered to. Voltage supply to EN5078, SELV, PELV. Disconnect power before connecting the unit as follows: Voltage output (PX9xxx) n.c. L+ L- Current output (PXxxx) L+ L- n.c. n.c.
