2.4 Structure & Handling
The shutter actuator (MDRC) contains of a programming button as well as a programming-LED which
indicates an activated programming button. In addition to the bus voltage, the shutter actuator must
also be connected to 230 V AC. Each of the inputs has two status LEDs, one for an active upward
movement and one for an active downward movement. A flashing LED indicates that the up/down
movement is currently active and a permanently lit LED indicates that the upper/lower end position
is reached. A manual operation is also possible via 4 buttons. Use the upper two buttons (right/left)
to select the channel for manual operation. Use the lower two buttons (up/down) to start an up or
downward movement.
The following illustration shows an 8-fold shutter actuator (MDRC):
