4.5.1 Controller independent circuit MC55Y
When working with 24 V supply voltage and 0 … 10 V DC / 2 … 10 V DC input
signal you can switch the actuator controller-independently via a three-step
toggle switch in the control cabinet.
 How to switch the actuator controller-independently
1 Run the supply voltage 24 V AC via a diode and a three-step toggle switch to
terminal Y.
2 Using the toggle you can move the linear actuator to the following positions:
• Closed-loop control by input signal Y (normal operation)
• 10 V-position
• 0 V-Position, the linear actuator can be moved to the position on the plug-in
jumper selected by jumper JP2 at 2 … 10 V DC .
