[3] Piano

These switches are used to set the various modes of the controller system.

Caution: When controlling the SCON controller via serial communication, always set the controller in the

“positioner mode” (piano switch 1: OFF).
If it happens to be in the “pulse-train mode” by mistake, the SCON controller may operate
erratically because it is operated according to the “pulse-train mode” parameters.
