Note: The actuator shaft is supplied slightly
extended by around 25mm (1"). This is to
allow the unit to be lifted without compressing
the springs on the louvre blades.
As soon as power is applied the actuator will
attain the correct positioning.

Maintenance Guide to Fa rm Electronics Moto rised Lo uvres.
The Farm Electronics Motorised Louvre is a robust product which is primarily designed
for installation in crop stores. By the nature of the ventilation systems in these buildings
the louvres are subject to extremes of temperature and humidity, and frequently
insta lled in inaccessible locations, making routine ma intenance almost impossible. O ur
experience has shown that the louvres w ithstand this lack of maintenance very well,
w ith the majority giving re liable service over many years.
However if the louvre is located in a position where access is possible a sma ll amount
of annua l ma intenance would obviously be beneficial in increasing the overa ll life
of the louvre. This ma intenance can be broken down in to three areas, visua l inspection
of the louvre, drive linkage and drive actuator.
Visual Inspection
The Louvre is manufactured from 16g Zintec eclectroplated steel which is further protected
after priming with vinyl micaceous iron oxide high build paint, which provides an extremely
tough weather resistance finish.
The louvre should be inspected for any damaged areas of paint which will over a prolonged
period of time allow rust to form, any damaged paint work should be touched up.
On the front of the louvre there is a brush seal at each end of each blade, (See Figure 1) the
condition of the brush seal should be checked.
Many louvres are insulated on the back of the blade with 20mm of rigid polyurethane foam,
(See Figure 2) this should be checked to ensure that it is firmly fixed to the blade.

Drive Linkage
In the centre on the back of each blade is a bracket which holds a nylon bush, the drive rod
runs through the centre of each bush and is joined at the top of the drive actuator via a lever
arm, where the drive rod passes through the nylon bush, it runs through a small spring under
the bush, (See Figure 3) this allows the blade to have a small amount of spring loading.
The Linkage should be inspected to ensure that it is straight and not
damaged, the nylon brushes require no maintenance, the spring
under each nylon bush should be smeared with light grease to prevent
the spring rusting or binding on the drive rod.
(Figure 3)
The pivot at each end of the blade is a stainless steel pin in a light
bronze bush, it is injected with Waxoil during manufacture and sealed
with a plastic cap, there is no further maintenance required.
Avoid application of products such as WD40 which are penetrating
oils and will quickly dry out and actually accelerate seizing.
We only recommend long term spray oils such as ROCOL Z30
Small Spring
under bush
Drive Actuator
The 220v-240v drive actuator is located top centre at the back of the louvre, (See Figure 4) the
actuator is fixed into the cradle bracket with two chrome set screws which locate into nylon pockets
in the actuator body, (See Figure 5) these screws should be checked for tightness. The design of the
mounting allows the actuator to pivot on the set screws and rock in a small arc during operation,
this pivoting movement is correct and must not be inhibited.
The mains cable is connected to the actuator with a special plug, during manufacture the pins and
rubber seal are coated with silicon grease, no further maintenance is required other than checking
that the small screw in the centre of the plug is tight. (See Figure 6)

Finally
Whilst you are near to the louvre ask a second person to operate the controls, watch the louvre open
and close, ensuring that it operates freely with out binding and pulls up the springs on the linkage.
Summary
Annually inspect the louvre for damage and correct operation, grease springs on drive linkage,
check that the set screws holding the actuator are tight and the centre screw in the actuator power
supply plug on drive is tight.
