Elster Kromschröder GmbH is presenting the actuator IC 40 with extended scope of functions and optimised operating software BCSoft.
The actuator IC 40 is designed for adjusting flow rates for combustion processes controlled by cycles and modulation and for any application that requires a precise, controlled rotary movement between 0° and 90°. A control ratio of 1:10 can be achieved here.
New operating modes ensure optimum adaptation to burner control requirements. In conjunction with burner control units BCU 400, both modulating and stage-controlled burner operation can be implemented perfectly. Besides capacity modulation, the central pre-purge function is also supported. The various device functions and running times can be set via an integrated infrared interface and transferred to other units. The universal device platform allows for considerable savings on logistics and commissioning costs.
The updated programming and diagnostic software BCSoft optimally supports setting and diagnostic procedures. The individual parameter settings for starting the actuators can be transferred from a PC to the actuators via an infrared interface. Current system states can be visualised in a status window. Burners can be adjusted independent of the central control system using the optimised manual mode in a separate program window. User and device statistics, together with the integral line recorder function, ensure the quickest possible system diagnosis in the event of a malfunction.
The costs of logistics is reduced as a result of the wide voltage ranges both for the mains supply from 100 V AC to 230 V AC, 50/60 Hz and for the digital inputs from 24 V DC / 100 V AC to 230 V AC, 50/60 Hz. The analogue input can be programmed for a wide range of tasks for 4 to 20 mA. A conductive plastic potentiometer, which is independent of the electronics system, is available to signal the precise position at all times. An optional safety closing function moves the valve to the closed position in the event of a power failure.
The actuator IC 40 is adapted to the butterfly valves BVH, BVA and BVG. The butterfly valves are installed direct on the actuator, without any adapters. The butterfly valve with stop BVH is notable for its very low leakage rate.
The high protection type IP 65 and the ambient temperature range from -15°C to +60°C mean that the actuator is suitable for a wide range of installations in sites with tough industrial environments.
The butterfly valve BVH is available in nominal sizes from DN 40 to 100.
The actuator IC 40 and the butterfly valve BVH create scope of new system concepts as a result of their great flexibility, based on their programmability.
