Linear actuators MC55
Operating Manual Version 3.3 - November 2014 21
5.5 Setting the limit position for MC55Y
Use Jumper JP2 to select a limit position for the linear actuator.
• JP2 ON: Limit position with extended spindle nut
• JP2 OFF: Limit position with retracted spindle nut
The limit position is approached in the following situations:
• Due to wire break detection by the Y signal (2 … 10 V DC or 4 … 20 mA
only),
• Due to a binary signal (When electric circuit between terminal B1 and B2 is
interrupted),
