Two PA actuators can be synchronized directly on site without any auxiliary equipment. You can find out how this works in this video.
The factory setting for ynchronous-capable actuator of the PA-series is SINGLE OPERATION. For synchronous operation, the actuator must be parameterized as MASTER or SLAVE, either by means of programming Ex Works (Art.No. SD1 8530), manual setting or with SICO LINK software. The manual MASTER-SLAVE setting is possible for a maximum of two actuators and can be carried out by the customer on-site.
