English For all available roduct documentation Product descrition The oerating instructions describe the entire function. The function is limited, deending on the roduct variant. You can find detailed secifications for the roduct, the device descrition file (IODD) with a descrition of the IO-Link arameters and the declaration of conformity at: Safety Intended use The ressure sensor SPAN is intended for monitoring ressure of comressed air and inert gases in the iing. General safety information Only use the roduct in its original status, without any unauthorised modifications. Only use the roduct if it is in an excellent technical status. The roduct is intended for use in industrial environments. Measures may need to be imlemented in residential areas for radio interference suression. Take into consideration the ambient conditions at the location of use. Oerate the roduct only with comressed air of the secified air quality class ( Technical data). Observe the secifications on the rating late. Comly with all alicable national and international regulations. Disosal Observe the local secifications for environmentally friendly disosal. Range of alications and certifications In connection with the UL marking on the roduct, the information of this section is also alicable for comliance with the certification conditions of Underwriters Laboratories Inc. (UL) for the U.S.A. and Canada. UL aroval information Product category code File number QUYX (USA) QUYX7 (Canada) E3346 Considered standards UL 6 C. No. 6 UL mark Fig. 3 Unit shall be sulied by a ower source which comlies with the requirements of a limited-energy circuit in accordance with IEC/EN/UL/CSA 6- or a Limited Power Source (LPS) in accordance with IEC/EN/UL/CSA 69- or IEC/EN/UL/ CSA or a Class circuit in accordance with NEC or CEC.. Overview 3 3 Function and alication The sensor converts neumatic ressure values (relative ressure) into electrical signals, which can be used for control or regulating functions. Measurements are carried out using a iezoresistive sensor element with a following electronic evaluation unit. Interfacing to the higher-level system is rovided by or switching oututs, an otional analogue outut and an otional IO-Link interface. The switching oututs can be configured for monitoring of a threshold value, a ressure or a differential ressure. The oututs can be set as PNP or NPN and normally oen (NO) or normally closed (NC). Via the IO-Link interface, rocess values can be read out and arameters changed and transmitted to additional devices Oerating statuses Dislay Electrical connection 3 Pneumatic connection 4 B-key button 6 A-key Fig. Reresentation of other variants can deviate from this.

Mechanical and neumatic An unfavourable mounting osition can imair the function of the roduct. Mount the sensor so that no condensate from the comressed air lines can gather in the device. Install the sensor so that it cannot be heated above the maximum ermissible oerating temerature (lan for convection ossibilities). ) SP.Lo = smaller ressure/vacuum value, SP.Hi = larger ressure/vacuum value, deendent on the Teach sequence Fig. 6 SPAN-...-G8M/R8M/N8M Seal connecting thread. Mounting bracket Auto difference monitoring d_ _ This funciton ermits monitoring of a ressure value for constancy. If the alied ressure is constant in the between [SP.Lo] and [SP.Hi], the reference ressure PRef is automatically determined. The result is a switching oeration at the outut. The signal change signals the start of ressure monitoring. If the ressure remains in the monitoring [d.sp] around PRef, the ressure is stable. When the monitoring is left (e.g. caused by a leakage in the system), the outut switches back. 3 mm max. 3,3 mm max., Nm 3 Fig. 9 Examle with G8M Fig. Examle with SAMH-PU-A-.
