Re-Engaging The Manual Release; Basic Maintenance; General - Centsys D3 User Manual

Re-engaging the manual release (A10 only)
It is strongly recommended that the gate is first pushed to the fully open
position, and then to the fully closed position before the release handle is re-
engaged. This is to ensure that no untoward behavior occurs due to the
system having lost its position information.

Basic maintenance

Basic maintenance
CENTSYS operators are designed to be maintenance-free. However, there are
some basic checks that should be carried out regularly (every six months). These
will increase the long term reliability of the system, and obviate false triggering of the
protection systems leading to erratic operation of the gate.
Isolate mains supply to system before cleaning or working on the equipment.

General

onto the operator pinion at any point along its travel.
Keep shrubs and vegetation clear of the motor, rack or chain.
Check that the key still operates the manual override access door or flap. Spray
with oil if necessary.
Keep the inside of the motor housing clear of insects and dust.
On operators fitted with a cooling fan, check that the air inlet ducts in the cover
and the outlet ducts in the gearbox are clear.
Keep the track clear of stones, dirt and
obstructions.
Ensure that all rollers are free.
In manual mode check that the gate runs
freely on its rail and does not catch or foul
against the walls or pillars.
Ensure that the gate wheels and guide
rollers are rotating freely and are not worn. In
high volume applications it will be necessary
to replace these components regularly.
Ensure that the rack is properly secured
to the gate and that it does not press down
