Barber Colman MZ2A

Complete user creation of custom control through block programming adapts MZII to virtually any HVAC sequence or mechanical system Models with battery backed up time clock true stand alone direct digital control optimum start stop scheduling func and battery backed up random access RAM Input output auto trending with adjustable rates continually accumulate and stamp last 48 analog values and last 10 changes of state Satellite point command capability from controllers eliminates of points half 0.5 second input to output times make MZII directly applicable static pressure fume hood and laboratory applications MICROZONE II Digital Controllers TAC NETWORK 8000 MICROZONE II MZII is a fully programmable controller that the TAC NETWORK 8000 Facility Management System family offering The has the ability to employ custom block programs and run them in a stand alone The MZII block programming language provides the system operator with 100 for creation of new and unique control strategies MICROZONE II is easily applied to a wide variety of mechanical equipment includ those that are application specific Through the Personal System Interface PSITM and Personal System Interface XPSITM control programs can be downloaded to all requiring the sequence of operation With the MZII the TAC NETWORK 8000 the best of both worlds full programmability for easy creation and modification custom control strategies and easy duplication of controller databases for mechanical containing similar or identical control strategies MZII utilizes state of the art surface mount technology which helps reduce the and cost of the product while providing powerful product features Modularity of along with the networking capabilities allow easy expandability as the needs of facility change in the future As with all other programmable TAC NETWORK 8000 the MZII utilizes non volatile EEPROM memory to store application control EEPROM memory allows an owner to modify existing control sequences or new ones through the Personal System Interface PSI asynchronous at 19,200 baud adjustable to global controller Modular jack for local connection of the Personal System Interface Terminal PSI can monitor all device parameters and has access to all program blocks and at for complete program editing and creation Provides up download capability system maintenance Device Access connected at one device has access to all network wide devices on an ASD com bus Connection of PSI will not disrupt the network communications the MZII controller and other devices on the bus NETWORK 8000 to 128 MZIIs
