Limit Switch Setting; Star-Delta Voltage Connection; Annual Check - Nice HDF-45-95 Instructions Et Indications D'installation Et D'utilisation

LIMIT SWITCH SETTING

The door must be balanced in all positions when assembling and
balancing with the weights according to the procedures prescribed
by the standards. Correct balancing is ascertained by manually
opening and closing the door with identical activation force in both
directions.
1. Electronic limit switches (transducer absolute value),
type A or type B (fig. 4-9)
The EES electronic limit switch is a positioning switch with absolute
value for rolling shutters, doors and main doors. The assessment, or
setting, of the final positions is carried out with gearmotors for doors
tuned to the EES.
During assembly simply insert the six­pole plug.
Particular mechanical settings and positionings are not needed.
The terminals for the safety chain (safety switch) are respectively
located on the EES side (type A) and on the plate beneath the EES
(type B). (Fig. 4 - 9)
See the EES wiring diagram in the gearmotor instruction manual for
the UST1-FU door.
2. Mechanical limit switch
The HDF series of gearmotors can also be supplied with mechanical
limit switch on request. It is recommended that these versions
be used combined with the UST1 or UST1K control units. More
information is available on request. You can also consult the control
unit instruction manual.

ANNUAL CHECK

BGR 232 directive "Windows, doors and main doors with mechanical
operation" is applied. It can be obtained from the National Insurance
Institute for Industrial Accidents of your trade association or from us
on request.
Maintenance interventions on windows, doors and main doors
with mechanical operation must be performed only by personnel
authorised by the company, having the necessary experience and
skills (BGR 232).

Warning! Danger of death due to electric shock.
Before starting the assembly operations, exclude the voltage from
the conductors and check that they are really equal to zero.
The commutability of the motor voltage makes it possible to use the
gearmotor on both a 3 x 400 V and 3 x 230 V power grid.
The motor is wired in the factory with star connection for a 3 x 400
V power grid.
For connection to a 230 V power grid, switch the motor onto a
delta connection.
To commute the voltage onto the motor, wire the ends of the
windings as illustrated in fig. 10-12.
When fixing the motor cables, pay attention that the cables are long
enough to consent solid fixing, in order to create a connection able
to remain secure over time.
Pull the conductors to check if the connection is secure.
It is necessary to also adjust the gearmotor (UST1-FU) by
commuting the motor for connection to a 3 x 230 V power grid. To
this regard, see the UST1-FU instructions.
Information for whoever carries out the checks
Gearmotor:
The mechanism is maintenance­free and it is provided with
permanent lubrication. Absolutely no rust must form on the output
shaft.
Fixings:
Make sure that the fixing screws are all in the correct position and
in perfect condition.
Balancing by weights (e.g. in the sectional main doors):
The door must be balanced in all the positions (see the door
assembly instructions) when balancing is done with weights
according to the procedures prescribed by the standards.
Brake (if present):
During the annual check perfect brake operation is to be ascertained.
In the case of heavy wear of the brake pads, it is necessary to
replace the complete brake. Before replacement, disconnect the
cables connected to the electric card.
