If you want to install ARCO rotator on a focuser with SESTO SENSO 2 focusing motor, first of all you will have to add one of the many available optional adapters based on connector you have on your focuser’s draw tube: you may choose between a nose or an adapter for different threads. In any case, first of all please connect the optional adapter to the ARCO body by tightening the 3 grub screws (that are inserted in the ARCO body) to locking it to the adapter. Then connect the ARCO to your focuser (this will vary based on your focuser specifications). Do not over tighten the grub screws otherwise you may ruin the thread or the inner adapter.
NOTE: Since ARCO may be not really close to the SESTO SENSO 2 focusing motor, we suggest the use of the 700mm length cable.
Now you can connect the cable from the ARCO port of the SESTO SENSO 2 to the port below the ARCO body. Take great care when connecting the cable to the ARCO port of the SESTO SENSO 2 and the port below the ARCO. Take a look at position of internal pins in the connector and rotate the cable connector until it corresponds to the port on SESTO SENSO 2 or ARCO. Then connect the cable with a gently press. If it doesn’t fit, please do not press too much the connector otherwise the internal pins may break.
ATTENTION: On the port of the ARCO rotator, the arrow position on the cable’s connector has to correspond to the white point. On the ARCO port of the SESTO SENSO2, the arrow position on the cable’s connector has to be set towards the ARCO label.
