Replacing actuators without integral controls by SIPOS 5 Reduced efforts: Retrofitting with phase sequence detection ~400 V Old Flexible: Installation of phase sequence detection within control cabinet or separately New ~400 V SIPOS 5 actuators can replace most electric actuators without integral controls. When replacing actuators in existing plants, the new technology has to be considered, as control of SIPOS 5 actuators with integral controls slightly differs from that of actuators without integral controls: The phase sequence detection is available in two versions, complete with wiring: Motor voltage switched B Actuator without integral controls U Phase sequence detection U UN = 3N~400/230V UN = 3N~400/230V 3N~400/230V L1 L1 SIPOS 5 L3 L2 L2 L3 5 10 L2 5 10 15 15 15 20 20 Off 25 ASYM ASYM [%] [%] 1 2 3 20 Off 25 ASYM [%] R R 4 5 6 AUF ZU SIPOS SIPOS 1 ~ 230 V / 3 ~ 400 V Automatic phase detection ensures that controls adaptation is kept to a minimum when replacing old actuators by SIPOS 5, as only minor wiring changes are necessary. Reversing contactors Signals Reversing contactors 24 V OPEN CLOSE A While for conventional actuators motor control is performed via phase sequence resp. reversing contactors, SIPOS 5 actuators are controlled via electronics, which only requires control commands. Signals Phase sequence detection on mounting rails (2SX5306-0PF00) Phase sequence detection in closed housing (2SX5306-0PF66) U U UN = 3N~400/230V UN = 3N~400/230V 3N~400/230V L1 L1 L3 L2 L2 L3 5 10 A Control of electric actuators without integral controls Electric actuators without integral controls are controlled via power controllers (reversing contactors or thyristors) in switching cabinets for clockwise, counterclockwise rotation. This means field actuators are operated with a switched motor voltage. B Simple: Phase detection makes time-consuming retrofitting obsolete The automatic phase detection converts the definition of the direction of rotation via the phase sequence of L1-L2-L3 (U-V-W) into binary 24 V OPEN-CLOSE signals. These signals are suitable for direct connection to the binary inputs of the SIPOS 5 actuator: Costly and labor-consuming, additional control cables to the DCS or PLC are not required. 1 2 3 R L2 5 10 15 15 15 20 20 Off 25 ASYM ASYM [%] [%] 20 Off 25 ASYM [%] R AUF ZU 4 5 6
