Introduction
This document discusses the replacement of electric actuators without integral controls with SIPOS 5 actuators. It highlights the control mechanisms, installation flexibility, and wiring requirements for the new system.

Specifications
SIPOS 5 actuators operate with a continuous voltage range of 220 V -10% to 230 V +15%, or 380 V -10% to 460 V +15%, within a frequency range of 40 to 70 Hz. They provide feedback signals as 24 V DC binary signals, which are galvanically separated via opto-couplers.

Control Mechanism
Electric actuators without integral controls are traditionally managed via power controllers like reversing contactors or thyristors. SIPOS 5 actuators, however, are controlled electronically, requiring only control commands. The automatic phase detection converts the direction of rotation into binary 24 V OPEN-CLOSE signals, eliminating the need for additional control cables.

Installation and Retrofitting
The phase sequence detection can be installed within the control cabinet or separately, available in two versions: on mounting rails or in a closed housing. This feature reduces the effort required for retrofitting, as only minor wiring changes are necessary when replacing old actuators with SIPOS 5.

Wiring and Power Supply
Existing signal cables can often be reused with SIPOS 5 actuators. If voltages exceed 24 V DC or currents exceed approximately 100 mA, relay sub-assemblies may be used. The electronics unit of SIPOS 5 is internally supplied with 24 V DC, and an external 24 V DC auxiliary voltage can be used to ensure actuator signals are available during power failures.

Conclusion
SIPOS 5 actuators offer a simple replacement solution for electric actuators without integral controls, providing flexibility in installation and reducing the need for extensive retrofitting.

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.

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
