IMPORTANT:
If only one actuator is connected to the FSC-UFC24-2 the LEDs of the side where no actuator is connected indicate an
alarm. A jumper has to be installed between S4 and S6 in the terminal where there is no actuator connected, to
indicate an “opened” position in the LED. If the second connection is not activated via bus, there will be no alarm signal
on the bus system.
