Faults: Troubleshooting - tau MASTER Serie Manual De Uso

MAINTENANCE
The MASTER series gearmotors require very little maintenance.
Nevertheless, their correct functioning also depends on the state
of the gate. Therefore here is a short description of the operations
to perform in order that the gate remains in good working order.
Warning: no persons, except the specialised maintenance
technician, must activate the automatic gate during the main-
tenance operations.
Therefore the power supply should ideally be disconnected there-
by avoiding possible electric shocks. If on the other hand it is nec-
essary that the power supply is connected for the said inspection,
each control device (remote controls, push button panels, etc)
should be checked and disabled except for those being used by
the maintenance technician.
Routine maintenance
Each of the following operations must be performed when neces-
sary or in any case every 6 months for domestic use (approx. 3000
working cycles) and every 2 months for intensive use, e.g. apart-
ment blocks (again, every 3000 working cycles).
Gate
- Lubricate (with oiler) the wheels of the gate;
- Check that the rack is clean and correctly connected;
Automation system
- Check that the safety devices are working correctly (photocells,
pneumatic edges, torque limiting device, etc..);
Extraordinary maintenance
If more complicated tasks need to be performed on the mecha-
nisms, the gearmotor should ideally be removed in order for the
work to be carried out by experienced technicians in the manufac-
turers or an authorised workshop.
SOUND LEVEL
The aerial noise produced by the gearmotor under normal use is
constant and does not exceed 70 dB.
SCRAPPING
The materials must be disposed of in accordance with the current
laws and regulations.
No dangers or risks are present in the event of scrapping of the
automation system.
If materials are to be recycled, they should ideally be divided based
on their type (electrical parts – copper – aluminium – plastic –
etc...).
DISMANTLING
In the event that the automation system needs to be dismantled
and reassembled in another location, it is necessary to:
- turn off the power supply and disconnect the entire electrical
system;
- remove the gearmotor from the supporting base;
- replace all components that cannot be removed or that are
damaged.

FAULTS: TROUBLESHOOTING

The gate does not open, the motor does not turn.
- Make sure that the photocells or sensitive edges are clean,
uninhibited and aligned. Proceed accordingly.
- Make sure that the electronic equipment is correctly powered
and check that the fuses are intact.
- Check that the functions are correct by means of the control
unit LEDs (see related instructions). Identify the possible fault.
If the LEDs show that a start command is active, check that
there are no remote controls, start buttons or other devices
keeping the start contact activated (closed).
- If the control unit is not working, replace it.
If the fault is not related to one of the above mentioned conditions,
replace the gearmotor.
The gate does not open, the motor turns but no movement
occurs.
- The manual release is still on. Restore the motorised function.
- Check if the gate is in contact with the mechanical stops. Man-
ually release the gate, move it and restore the motorised func-
tion. Check and correct the position of the limit switch pads.
- Check that the gate has no mechanical adjustment defects.
If the fault is not related to one of the above mentioned conditions,
replace the gearmotor.
