1)
Only for Type SAM-20 to -50: Provided S6 is connected, only one potentiometer (R1) can be
connected in plug-type connections.
2)
Only for Type SAM-20 to -52, optionally with potentiometer R1/R2 or position transmitter ESR
3)
Only for brake motors or synchronous motors for 230 V, 50 Hz; for three-phase a.c. motors, external
reversing contactors are required.


Two switches S4 and S5 to signal intermediate or final positions
