STEP 7 : Connecting the Safety Brake with the Electronic Board
Using a 2x0.5mm cable, we connect the safety brake to the board in the position of the NC D , for
boards FBM-0, or Safety Brake on boards like FBM-1 and FBM-2, before removing the existing bridge
(throughout 2x0.5mm cable is transferred only command and not electricity). The cable passes over the
roller shutter, either in an electrical channel, or on the building chosen positions, selected by the installer
of the installation workshop.
In the event that the safety brake switch is opened (opening) (for example, the curtain is suddenly
descending), the electronic circuit commands motor’s shutdown.
STEP 8 : Adjusting the Terminal Switches of the Industrial Roller Shutter
At first, we connect the electronic board with the manual
control knob (Figure 8), watching the BROWN wire being connected
to the ASCEND button and the YELLOW cable with the DESCENT
button. Then we feed the board with three-phase current and start
the process of adjusting the terminals switches.
Figure 8
By pressing the DESCENT button, we see in the terminal control board (Figure 9) that the rotors
move to the right. In case, that this does not occur, we invert the two of the three power supply phases,
but in no case do we change the motor wiring to the electrical board.
This matter can only be observed in roller shutter assemblies equipped with a FBM-0 electronic
board, which does not have a phase sequencer. In contrast to the devices equipped with FBM-1 and
FBM-2, the error is detected and indicated by means of a light bulb, whereby reversing of the phases is
carried out without requiring testing the roller shutter.
Afterwards, we lower the roller shutter until the bottom bar comes into contact with the floor. In
this position, we must adjust that the right rotor, controlling the descent, presses the corresponding
contact. To manually move the rotor it is necessary to snap the locking screw, thus allowing it to rotate
freely. After completing the previous procedure, tighten the screw again by turning it by hand and not by
