ZN SERIES ACTUATOR
Flashing light connection:
Terminal 5 ÷ 6 24V D.C. connection (max 34V) not adjusted, max
1A
Cleaning the chain and the guide
If the chain (7) or the guide (8) are very dirty, clean them with a
clean cloth.
Every year lubricate slightly the chain with conductive oil.
Do not use grease!
N.B. Use only conductive oil.
1- Fuse for flashing light connec-
tion, terminals 5 ÷ 6, 1A with
delayed action
Replacing the switchboard lamp
- Remove the electrical plug from the socket
- Unfasten the screws (1)
- Remove the transparent cover (2)
- Turn the lamp (3) leftwards and remove it.
- Insert the new lamp (24V, 21W, BA 15s type) and turn it rightwards until the end.
Replacing the switchboard fuses
- Remove the electrical plug from the socket
- Unfasten the screw (1)
- Remove the transparent cover (2)
- Pull off the control circuit board (3)
- Replace the faulty fuse. All fuses are 1A delayed
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).
