LB-762 Controller Installation Manual LAB-ELRozdział 1System descriptionRegulator LB-762 is used to control a single mushroom cultivation hall. It provides all necessary measurements and controlover appropriate executive devices to ensure optimum climatic conditions for fungi cultivation.LB-766 controller is used to control a single storage room. Regarding installation details, it is identical to LB-762 controllerand this manual is applicable to both types.For a greater facility, consisting of more cultivation halls, each hall must be equipped with a separate regulator. In this caseit is possible to connect all the regulators into a common measurement-regulation system. In such system each regulatoroperates autonomously, but it is possible to control together all the regulators from one PC computer and appropriatesoftware. Additionally, it is possible to perform some functions common for the entire system, such as measurement ofexternal air parameters or CO2 concentration measurement.Regulator LB-764 is LB-762 model with special modifications prepared for ”Baltic Champignons”, installation instructionsalso applies to this regulator.1.1 External connections of a single LB-762 regulatorFigure 1.1 presents a scheme of typical external connections of a single LB-762 regulator. To the regulator one should attacha set of suitable measurement probes and executive equipment so that it could perform its functions.Rysunek 1.1: External connections diagram of LB-762 regulator1.2 Measurement probes• Psychrometers – are used for measurement of temperature and relative air humidity. The regulator may co-operate withor one two psychrometers (at least one is required for proper operation of the regulator). Attaching one psychrometerprovides one-point air temperature and humidity measurement in the cultivation hall. The second psychrometer may beoptionally used for temperature and humidity measurement elsewhere in the cultivation hall, for better averaging of the4
