BULLETIN The BLENDTECH MARK V SMART ADDITIVE INJECTOR unit is a modern electronic microprocessor based injector package designed for use in a variety of chemical additive applications. The unit is suitable for indoor or outdoor use Document Number: MKV_77x8_001 BLENDTECH Product Bulletin MARK V 77x8 Injection System Product Description System Description The MARK V SMARTADDITIVE INJECTOR package processes and displays the data required for accurate control of additive injections. The MARK V unit normally operates as an intelligent slave to the main product transfer system but can also operate as a stand alone unit. When enabled, the MARK V unit monitors the main product flow meter and causes the additive to be injected in proportion to the main product flow. Control of the additive is accomplished by a solenoid operated flow control valve. Should the MARK V unit be unable to maintain the required injection rate, an alarm is generated and the “permissive” output circuit is turned off. The MARK V is capable of producing up to sixteen different product blends. The MARK V unit maintains it’s own internal calibration factors for both the main and additive flow meters and all user changeable parameters in nonvolatile memory in the MARK V unit. These parameters may be changed via the unit’s front panel or through a RS-485 serial channel or via the IrDA communications link. The RS-485 party line and IrDA communications circuits permit monitoring and control of the MARK V unit. The MARK V is compatible with BLENDTECH’s BlendCOMM Management and Control Software Package. The MARK V uses the FLEx iO input output signal structure. All digital inputs and outputs are completely user configurable. Over 250 signals can be assigned to nine inputs and six outputs. Four outputs use industry standard, colour coded, optically isolated, fuse protected, solid state relay modules. Five FLEx iO Auxiliary IO are also available for special operation and control functions. The MARK V is configured with a 2 line 16 character vacuum fluorescent display, suitable for low temperature operation. The display supports multi-language operation.
