FAAC 413 - Limit Switches

ENGLISH
4.7. Limit switches
The “LS” models are equipped with opening and closing limit switches. Therefore they require the use of a control board able to
control these inputs.
Note: The limit switches are triggered for the first and the last 30 mm of the travel. Therefore the operator should use the
whole available travel during the opening phase. Shorter travels can limit or completely cancel the limit switch
adjustment range.
4.7.1. Wiring the limit switches
The limit switches are wired in the same terminal board where the motor wiring has been carried out. Wire the limit switches as follows:
1) Open the second pre-drilled hole in the cover, Fig.21.
2) Fit the supplied cable gland, Fig.21
3) Insert the cable and connect it to the terminals observing the colours specified in the table of Fig.22.
4) Close the cover with the four supplied screws.
Notes:
• For the limit switch connection use the cable for the external movable laying with wires having a cross section of 0.5
mm
2
.
• During the wiring operations, observe the wire colours as specified in the table of Fig.22.
4.7.2. Adjusting the limit switches
The limit switch adjustment is carried out as follows:
1) Remove the two plugs which cover the lower securing screws, Fig.23 ref.1. To facilitate this operation, a slot is provided for inserting
a screwdriver.
2) Unscrew both lower screws of the front cap and remove the cover, Fig.23.
3) Loosen the fastening screws of the limit switch to adjust, Fig.24 ref.A.
4) Move the limit switch to the desired position and lock the screws.
5) Perform a pair of test cycles to check the correct position of the limit switch. If the
adjustment of the limit switch needs to be carried out again, repeat the operation
starting from point 3.
