Maintenance

Information
Periodically check the proper functioning of the operator. Do this check at least every 6 months (EN12453)
!
Warning
Maintenance must be performed only by skilled technicians.
!
Warning
Before doing any maintenance job, turn the operator OFF by means of the differential switch of the electric system.
• Grease the joints with graphitized grease every year.
• Check the general condition of the gate structure.
• Check the mechanical resistance of hinges, operator mountings and stops.
• Ensure the installed safety devices are in working order (photocells, rubber barriers,...) and adjust the thrust force at the end of the gate leaf (max. 147 N).
• Ensure the electrical system and the differential switch are efficient.
• Check the setting of the pressure relief valve.
• Check the tightening of the safety lock.
• Depending on the use of the operator, check the oil level of the system.

Troubleshooting

Fault type
By operating the opening control, the
leaf does not move and the electric
motor of the operator does not run.
By operating the opening control, the
electric motor of the operator runs but
the leaf does not move.
During the motion, the operator jerks.
Probable cause
No power supply.
Defective fuse.
The power cable of the operator is damaged.
The operator has a hydraulic release,
check that the release valve setting is
closed.
If the operator has been exposed to the sun for
a long period, with the gate closed, check that
the operator piston is not in the fully advanced
position, i.e. with the rod completely out.
Probably air in the cylinder.
Oil in the cylinder not enough.
The front and rear operator mountings
move or have been fitted incorrectly.

Solution
Turn the power on.
Replace the defective fuses with new ones having
the same amperage.
Replace the power cable and find and rectify
the fault.
Turn the valve fully in a clockwise direction (E8 pos.1).
Check the operator mounting, as described in
this manual.
Check the measure of the piston stroke.
Detach the operator from its front mounting
and make a few opening and closing movements;
then re-fit to the front mounting.
Check for oil leaks; if any, address to an
RIB Repair Centre.
Repair or strengthen the mountings.
