Installation Advices
1)
The control should be installed as near the gate as possible.
2)
If this is not possible, you should:
Use cables with proper sizes.
Never use a multiwire cable to connect either the motor or all the services (open, close, block,
photocell, end-run), but ALWAYS SEPARATE THE POWER from the Low Tension
(controls and securities) using more cables.
In case of threephase 400V supply it is necessary to place the control near the gate in order to have
the shortest way of the power wires , always separating the low from the very low tension.
If it is not possible, so it is necessary to use screened cables, remembering to earth the cable screen
at the two ends.
3)
After every installation check, with a tester Vac., that there isn’t any induction tension on the en-
ters, measuring between the earth and one end of the “Open button” terminal block. If there is an
“Alternating tension” below 20—30 V (induced tension for cable passage with supply) the system
is ready to be tested, otherwise it is necessary to overhaul the cable arrangement as described abo-
ve.
Max Loads and Maintenance
The relays set on the control have a load of 9 Amp. And they must be, relating to their load, periodically
checked.
It is advisable to overhaul the relay contacts every 4 years, but always according to the following condi-
tions:
Micro 6R control 400V threephase supply
Max. load permitted : 2,2kW
Threephase motor cosØ = 0,7
N° of possible movement: 500.000
Micro 6R control 230V threephase or monophase supply
Max. load permitted : 1,5kW
Threephase motor cosØ = 0,7
N° of possible movement: 500.000
WARNING: Reducing the motor cosØ the n° of possible openings decreases (ex. with cosØ = 0,3 the
number of movement is halved).
Check always the values of the installed motors
WARNING
: The above specifications are adressed to technicians and/or qualified staff.
All checks and works should be made OUTSIDE the electric and electronic details of the controls.
Never forget that installations should be made according to law requirements and “Rules of good
installation”.
It is advisable to protect the control, at least on the upper side, if it could be subject to inclement
weather.
The ALLTRONIC snc states that the control has been registred.
Therefore the central will be protected in all its parts by the law.
It is forbidden to riproduce any part of this manual without written authorisation of the Alltronic
