Issue How to measure absolute pressure in an air system? Environment SPD310, SPD360 Cause Only Differential air pressure sensors are listed in the catalogue. Resolution The SPD310 & SPD360 are the only Air Pressure transmitters we have in the Sensors Catalogue, however these should be suitable for measuring pressures most Air based systems. They can be used to measure the differential pressure across fans or dampers, but you can leave one side of the sensor open to the plant room atmospheric pressure and the other side connected in to the duct, that way it will measure the pressure in the duct relative to that days atmospheric pressure. This method will mean the air pressure coming out of the system relative to the room remains constant as atmospheric pressure changes. The SPD360 has the added local LCD display showing the differential pressure in Pascals. Note: There are air pressure switches and meters also available in the catalogue.  

Issue What are the cable specifications for wiring controller inputs to field devices. Environment Inputs Cable Sensors End devices Cause There is no specification for IO field wiring.   Resolution The line drop produced by cable resistance should be taken into account when choosing the wire gage for Input devices.

Issue Vista events from a standalone Xenta 5xx must be adjusted. Product Line TAC Vista Environment Vista Event Logging Xenta 5xx Cause Situations where the Xenta controller must handle more events while in a "standalone" installation. Resolution In Xenta firmware versions >5.1.3 it is possible to change the event storage capacity of the Xenta with a console command "eventcap". The variable of eventcap allows the user to define how many event storage files Xenta may have. The valid number range of events is from 10 to 2000. Each file stores ~150 events, depending on event size. Example: 700 files are recommended to store ~100,000 events. Note: This only works for Vista events, not I/NET. I/NET uses another memory module of the Xenta device and will not be affected with this change.
