8. ACCESSORIES
Limit switch kit
The limit switch kit makes it possible to stop the garage door
in two specific positions.
It can be fitted on the FAAC 593 operator only if the 596 MPS
card has been installed on it for this function. When this
requirement has been met, proceed as follows:
1.
Extract the shafts from the pinions, and mount the
cams.
2.
Remove the screws holding the operator onto the
longitudinal sections, add the flat washers provided
and mount the limit switch supports.
3.
Tighten the screws, and fit the limit switches into their
seats.
4.
Open the garage door to the required point and turn
cam A of microswitch FCA until the microswitch is
activated.
5.
Close the door to the required point and turn cam B of
microswitch FCC until the microswitch is activated.
6.
Tighten the self-tapping screws on the cams.
9.
MAINTENANCE
When performing maintenance always check that the by-
pass screws are set correctly, that the system is balanced
and that the safety devices operate correctly.
9.1.
TOPPING UP WITH OIL
Check periodically the quantity of oil inside the tank.
For medium/low duty cycles a yearly check is sufficient; for
more severe operation it is advisable to check every 6
months.
The oil level must not be lower than the index line.
To top up, unscrew the filler cap (fig. 16) and pour in oil up
to the correct level.
Use exclusively FAAC XD 220 oil.
9.2.
BLEEDING AIR FROM HYDRAULIC CIRCUIT
If the beam moves in an irregular manner, this may be due
to the presence of air in the hydraulic circuit.
If it is necessary to bleed the air, proceed as follows:
1)
Check that the breather screws have been removed
(fig. 16).
2)
Disassemble the lateral drive shafts from the operator.
3)
Set an operating time of about 1 minute on the
electronic control unit.
4)
Activate the operator electrically so that it turns to the
end of its travel in both directions of rotation.
5)
Repeat this operation several times if necessary.
6)
Follow the installation instructions to reassemble.
