Control of filter circuits in a swimming pool with AS-i
Requirement
The task of filters is to keep dirt particles from swimming pool water and, consequently, to increase the water quality. They require regular backflushing to ensure their function. The controller must carry out the filter backflush processes independently and fully automatically - to relieve the staff and the higher-level control system.
Implementation
AS-i is used for wiring and as the control system. With its Profibus DP interface, the AS-i controllerE AC1305 operates as a slave in the central controller. The pneumatic quarter-turn actuators used are equipped with sensors of the T5 series for actuator feedback (order no. AC2316) to pick-up and control the end position signals.
Customer benefits
The simple wiring and set-up of AS-i systems and field modules provides economic advantages as regards labour costs and material costs. Thanks to the high protection rating and direct mounting on the actuator, the installation times of T5 are reduced as compared to conventional control boxes. Status LEDs for on-site diagnosis and the display of the controllerE provide a high degree of plant transparency.
