This manual is also suitable for

The ZN10 operator integrates perfectly with the design of any up and over door with-

out essentially altering its appearance. It also features quiet and linear operation

which renders it safe and agreeable to use, thanks not least to a courtesy light timed

to switch off after 3 minutes.

Total safety

The use of low voltage motors (12 V) eliminates any risk of electrical discharges or

accidental electrification of the structure.

Electronic clutch

if the door is obstructed by an obstacle, an electronic device will immediately stop

the automatic system as soon as the slightest hint of abnormal friction is detected,

and reverse the movement by about 10 cm.

Easy to install

Simpler electrical installation thanks to the separate control unit, optimizing mainte-

nance and assembly (can be connected to the power supply using an existing sock-

et). The control unit lights up automatically (when the motor is activated) and has a

button for opening and closing the door. The absence of any “control head” at the

end of the mechanism, and consequently the reduction in length of 310 mm, is espe-

cially advantageous in situations where space may be limited.

Maintenance-free and reliable

With the new operating principle of a motor travelling along a fixed chain in a track,

the automatic system is quiet and long-lasting, and requires no maintenance.

MAINTENANCE

Before carrying out any cleaning or maintenance operations on the motor, switch off the power by means of the appropriate magne-

tic/thermal switch upstream of the control unit and disconnect the back-up battery.

If the power supply is needed to carry out operational checks, disable all control devices (radio controls, keypads, etc.) except for

the device used by the maintenance technician. In general, the ZN10 electromechanical actuator requires little maintenance, but cor-

rect operation also depends on the condition of the door.

Both ordinary and extraordinary maintenance must be carried out by a specialised technician.

Routine maintenance:

Each of the following operations must be carried out on an “as necessary” or at least once every 6 months basis.

- If the chain is very dirty, clean it with a cloth.

- Lubricate the track with "conductive" oil

- Check that all the screws are tight, and if necessary tighten them.

- Check spring compensation and the up and over door mechanism.

Automatic system:

Check that all the safety devices (photocells, pneumatic stops, etc.) are operating properly, at the times and in the manner descri-

bed by the manufacturer (see safety instructions).

Extraordinary maintenance:

Extraordinary maintenance operations are not anticipated, however if major work involving the mechanical parts is necessary, it is

advised to remove the actuator for repair (by specialised personnel).
