Returning To Normal Operation; Maintenance - FAAC 620 Manual

- Insert the standard key (Figures 19 a) or the personalised
key (Figures 19 b) in the lock and turn anticlockwise by
one revolution.
- Open or close the barrier manually.

7. RETURNING TO NORMAL OPERATION

To prevent an accidental impulse from activating the
barrier, turn off the system's electrical power supply before
returning to normal operation.
triangular key (standard):
- turn the key clockwise until it stops, then remove it (Fig.
19a).
personalised key (optional):
- turn the key clockwise until it stops.
- turn the key anticlockwise very slowly to the point where
it can be removed (Fig. 19 b).

8. 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.
8.1. 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 level must not fall below the level mark on the inspection
window (Fig. 20).
To top up, unscrew the filler cap (Fig. 20) and pour in oil up
to the correct level.
Use exclusively FAAC XD 220 oil.

8.2. BLEEDING AIR FROM THE HYDRAULIC CIRCUIT
If the beam moves in an irregular manner, this may be due
to the presence of air in the hydraulic circuit:
1) Remove the breather screw (Fig. 9).
2) Actuate the beam electrically:
- while the beam is opening, slightly loosen the bleed
screw on the piston with balance spring, then
retighten it (Fig. 1, pos. 33);
- while the beam is closing, slightly loosen the bleed
screw on the piston without balance spring, then
retighten it (Fig. 1, pos. 11).
If necessary, repeat this operation, until you obtain a
smooth beam movement.
9. REPAIRS
For repairs, contact an authorised FAAC Service Centre.
10. ACCESSORIES
OPTIONAL ELECTRONIC BOARDS
The three boards - SLAVE, FSW and RELAY - provide
supplementary functions for the 624MPS unit, and may be
used simultaneously.
Carefully read the instructions supplied with each product.
624 FSW board (Fig. 21)
The 624 FSW board manages the operation of photocells
in P logic (Parking).
To prevent trespassing, the closing safety device causes
the beam to stop, then to close again on disengagement.
624 SLAVE BOARD (Fig. 21)
The SLAVE board manages the simultaneous operation of
two opposing barriers.
One of the two barriers is identified as MASTER, the other
one as SLAVE.
