Before performing any maintenance, disconnect the mains power
supply. If the disconnecting switch is not visible, apply a "ATTEN-
TION - Maintenance in progress" sign. Restore the power supply once
maintenance is complete and after tidying up the area.
!
Maintenance must be performed by the installer/maintenance techni-
cian.
Comply with all the safety instructions and recommendations provided
in this manual.
Close off the work site and prevent access/transit. Do not leave the
work site unattended.
The work area must be kept tidy and clear upon completing mainte-
nance.
Before starting activities, wait for the components subject to heating
to cool down.
Do not modify the original components in any way.
FAAC S.p.A. disclaims any liability for damage caused by components
that are modified or tampered with.

7.1 ROUTINE MAINTENANCE

The table  Routine maintenance ( 1 6 ) lists a rough guide of
routine operations, which are guidelines and are in no way exhaustive,
to maintain the automation efficient and safe. It is the responsibil-
ity of the machine installer/manufacturer to define the maintenance
schedule of the automation, integrating the list or changing the
service intervals based on the features of the machine.

7.2 OPERATING PROBLEMS

 7 Guide to solving malfunctions
CONDITION
The gate does not perform the
SETUP
The gate does NOT OPEN
The gate CLOSES instead of OPEN-
ING and vice versa
The gate performs movements at
very low speed
The gate only moves for short
stretches
Irregular movement (jerks)
Excessively noisy automation

BLEEDING

1. Remove the protective caps (1 9-1).
2. Command the gate to open. During the stroke of the leaf, loosen
the screw (1 9-2A or B): oil emulsified with air leaks out.
3. Tighten the screw before the leaf completes the stroke.
4. Command the gate to close. During the stroke of the leaf, loosen
the screw (1 9-2A or B): oil emulsified with air leaks out.
5. Tighten the screw before the leaf completes the stroke.
Repeat the procedure until non-emulsified oil comes out.
6. Set the protective caps back in place (1 9-1).

TOPPING-UP THE OIL LEVEL

1. Remove the cap (1 9-3). Check the oil level: it should be just
below the cap.
2. Top-up, if necessary. Set the cap in place again.
!
Only use FAAC oil.
Perform bleeding after topping up the oil level.

SOLUTION
ensure the actuator is not blocked
check the presence of the power supply
check motor and encoder connection
check for faults/errors in the actuator or encoder
invert the motor connection phases and perform
a SETUP
check the set force
check the set slowdown spaces
check the encoder connection
check for errors in the encoder
check for air in the hydraulic circuit. Bleed
there is air in the hydraulic circuit. Bleed
check the verticality of the leaves
