Selection of sequence mode, control range defined 

by SW 5

Modulating Control 0-10Vdc 

(DIP n. 2 OFF only)

Modulating Control 2-10Vdc 

(DIP n. 2 OFF only)

5

Sequence Control 0-5Vdc  with DIP n. 4 OFF only 

Sequence Control 2-6Vdc  with DIP n. 4 ON only 

(DIP n. 3 ON only)

Sequence Control 5-10Vdc  with DIP n. 4 OFF only 

Sequence Control 6-10Vdc  with DIP n. 4 ON only 

(DIP n. 3 ON only)

6

Voltage Input Signal 

(input between Y [+] and M [-])

Current Input Signal 4-20mA (input between Y [+] and 

M [-]). 

In this case DIP n. 4 must be set to ON.

Automatic Calibration: the actuator updates the 

stroke range every time an unexpected mechanical 

stop is detected for at least 10s

Manual Calibration: the actutor calibration is started 

moving the DIP from OFF to ON; if the DIP is left in ON 

the actuator will never update the calibrated stroke 

value even when an unexpected endpoint is detected
