Jumpers J1-J4 on the PCB
The positions of the jumpers are only read once as the device boots (= when supplying it with power).
If the jumpers are adjusted during operation, their positions will only be updated if the device is re-
started.

Through adjustment of the jumpers (J1-J4), the following settings can be made.
- Page 2 Reference drive The SMS14 detects the position of the step motor via a reference drive. The step motor will be closed or opened completely, and the SMS14 gains its orientation via the reference drive. If Jumper J4 is set, the SMS14 opens the step motor completely, and defines the position “0%” as the step motor being completely open.
- Page 3 Depending on the model of the motor, it is connected using 4 or 6 terminals. SMS14B (4 poles, bipolar) SMS14U (6 poles, unipolar) Super-capacitors (optional) 3 super-capacitors can be connected on the right side of the module. These serve as emergency power supply, allowing for the valve to the opened or closed during a power outage.
