Model 6000 is a permanently installed pressurization system intended to provide ”px” purge and pressurization in accordance with IEC 60079-2. Instructions and markings are provided with the control system indicating how to install this device to the electrical enclosure to be purged and pressurized in accordance with IEC 60079-2. The pressurization system enclosure is composed of stainless steel and has an IP66 rating. It is comprised of a cover and body, power supply and main controller, user interface, temperature hub, up to three temperature sensors, vent; optional I.S Termination Board DIN mounted, optional temperature hub and up to three temperature sensors when the temperature hub is provided. The power supply and main controller are housed in a flameproof (”d”) enclosure. The user interface, temperature hub, temperature sensor, and vent are intrinsically safe (”ib”). The control system enclosure contains the IS interface board, which has connection facilities for intrinsically safe circuits. The IS interface board is provided with five connection facilities that have assigned entity parameters.
Please see Annex for additional information.
Issue 1: The revision includes the additon of the pressurization system component kit, Model 6000-XX-XX-XX-CK-XX.
Issue 2: Addition of intrinsically safe "ib", Temperature Module and Temperature Sensor.
Issue 3: The manfacturer has updated the gasket used on the main unit enclosure, two resistors within the intinsically safe circuits, the thickness of the material on the intrinsically safe wiring partition and the addition of an alternate material for intrisically safe wiring partition. Also, updated to IEC 60079-1 Edition 6 and IEC 60079-2 Edition 5.
Issue 4: Addition of dust certification to temperature sensors/Hub and updated IEC 60079-0 edition, alternate components, and IP66 enclosure rating.
Issue 5: Update to drawings regarding the IS Termination Board DIN Mounted, Model 6000-ISB-XX.
Issue 6: Removal of the SciCron Coating from the Keypad.
