ASSEMBLY INSTRUCTIONS /
FIXING THE MECHANISM
According to the VDE 0113 booklet, the emergency stop
devices must also be perfectly efficient regardless of the
gearmotor operation mode. Any release of the emergency
stop device must absolutely not cause an uncontrolled or
undefined restarting.
OVERTURNING MOMENT: The fall of the balanced door
wings by weights can be avoided if the gearmotor is still able
to support the wing weight even if the spring breaks.
This provision is based on the regulations of the National Insurance
Institute for Industrial Accidents BGR 232. The static overturning
moment is the maximum load allowed for the mechanism at the
time the spring breaks.
The Mstat static overturning moment is calculated with the following
formula:
Mstat [Nm] = Wing weight [N] × cable winder drum radius [m]
Considering that two balancing springs can yield at the same time,
the Commission of experts on the subject of building devices
recommends sizing the gearmotor so that it is able to support
- the total weight of the wing when there are one or two springs
- 2/3 of the weight of the wing when there are three springs
- 1/2 of the weight of the wing when there are four springs.
Pursuant to the directives mentioned above, the considerably
greater gearmotor breaking load is not to be contemplated in
defining the gearmotor sizing. In the case of cable winder drums of
the scalar type, the greater winding diameter is to be considered.
Consider the allowed forces of the cables!
GENERAL DANGER WARNINGS AND
PREVENTIVE SAFETY
Clutch gearmotor
The gearmotor is to be pushed not too forcefully on the relevant part
of the previously greased flexible shaft.
The key (tab) is to be blocked on the through seat of the shaft with
1 screw (or, as an alternative, with a fixing ring) to prevent accidental
movement (Fig. 1).
There are fixing holes (on the bracket) o secure the support (bracket)
to the reduction unit flange.
Precise fixing of the support (bracket) is specified in the instructions
of the main door (Fig. 2).
Fixing must be performed using 4 M 8x12 screws and the washers
supplied. Tightening torque must be 20 Nm. The support is to be
secured on the building side with 2 8/M10 screws.
The manual emergency release is envisaged for opening and closing
the door in case of power failure, so it is to be used only in emergency
situations.
- Avoid regular use!!
Warning! Danger of injury in the case of incorrect use!
- Deactivate the main switch before using the manual emergency
release.
- The manual emergency release is to be executed only with the
motor stopped.
- The manual emergency release manoeuvre is to be executed
from a safe place.
- With a gearmotor equipped with brake (pressure), the main door
EMERGENCY MANUAL RELEASES
must be opened and closed with the braken open (released).
- On doors not balanced with weights, the brake is to be released
only for checking purposes with the door in the low position for
safety reasons.
- An undesirable brake release must be prevented with an adequate
check (measurement) on site.
The manual emergency release must not move the door beyond
the final positions because in this case the main switch would
activate.
Therefore, operation of the door in electrical mode is no
longer possible.
Handle-operated manual emergency release (fig. 3)
- Insert the handle exerting moderate pressure, then turn it up
to when it clicks in position. In this way the control voltage is
interrupted and the door can no longer be activated electrically.
- Open and/or close the door turning the handle
- The control voltage is reset and the door can again be activated
electrically by removing the handle.
Manual chain-operated emergency release (fig. 4 and 9)
- Movement to the right or left activates a microswitch that will cut
out the voltage going to the reduction unit, afterwards the main
door can be opened or closed by pulling the chain.
- After releasing the chain, the voltage will be restored and the
reduction unit will once again be operational.
Average duration: 200 cycles!
Manual chain-operated emergency release 2 (fig. 5a-d)
- Grasp the red handle / manual control (1) and softly pull until
stopping to interrupt the control voltage, and therefore prevent
activation of the door in electric mode.
- Open and/or close the door with the emergency release chain (2)
- Grasp the green handle /motor control (3) and softly pull until
stopping to restore the control voltage, and therefore once again
consent operation of the door in electric mode.
Average duration: 350 cycles!
Interlocking release (fig. 6)
- Pull the red cable to release the gearmotor.
- Manually move the door upwards or downwards.
- Pull the green cable to once again lock the gearmotor.
Modification of the length of the emergency release chain
(fig. 7)
- The emergency release chain opens in the connection point and
therefore can be extended or shortened by adding or removing
links.
- The links must be carefully bent.
- When the emergency release chain length is modified, it is
necessary to pay attention
WARNING: Max. chain length: 14 metres - max. assembly
height 8 m!!!
NOTE: with chains having lengths min. 15 metres it is
necessary to use the “2” chain release.

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. Mechanical limit switches
The upper and lower deactivation positions of the door are defined
by setting the limit switch.
The gearmotor must be electrically connected for making this setting.
To access the limit switch (fig. 8: CIRCUIT BOARD WITH 6
SWITCHES/CAMS) unscrew the limit switch guard. It is possible
to move the door in dead man mode using the built-in “OPEN”,
“CLOSE” and STOP buttons if the external control devices have not
yet been connected with the control station included in the supply.
Switch off the power and reverse the two L1 and L2 phases of the
gearmotor if the door does not open when pressing the “OPEN”
button.
The door must open even if the gearmotor has been installed upside
down when the “OPEN” button is pressed. Otherwise, switch off the
power and reverse the two L1 and L2 phases.
It is also necessary to properly correct the two emergency stop limit
switches so that they trip after the limit switch.
Switching off with door in low position
The limit switch for switching off with door in low position is to be set
as follows (fig. 8):
Move the door to the desired CLOSE position.
Set the contactor cam 3 E(white) to activate the limit switch.
Tighten the fixing screw A.
For accurate adjustment, turn the screw B.
Move the door into the desired OPEN position
Set the contactor cam 1 E(green) in order to activate the limit
switch.
Tighten the fixing screw A.
For accurate adjustment, turn the screw B.
The safety limit switches 2 SEand 4 SE (red) must be set in order
to be released right after the overtaking of the control limit switch.
The safety limit switches 2 SEand 4 SE (red) are factory-set in
order to follow the limit switch at a short distance.
Check that the fixing screws are in the correct position after the
operation test.
The additional limit switches 6 P1and 5 P1are switching contacts
with zero potential.
In automatic mode limit switch 6 is used as a preliminary limit
switch. Therefore it is to be set so that it releases when the door
reaches a distance of 5 cm from the ground.
In dead man mode it is not necessary to set it and it is used as a
contact with zero potential.
2. Electronic limit switches (transducer absolute value),
type ENAS003 and type KOSTAL (fig. 10 and 11)
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 six-pole 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 ENAS003) and on the plate beneath
the EES (KOSTAL type). (Fig. 9 and 10)
LIMIT SWITCH SETTING STAR/DELTA VOLTAGE CONNECTION
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. 12-15.
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.

NOTE: all the technical characteristics indicated refer to a temperature falling between -5°C and +40°C. • Nice reserves the right to
change all the modifications to the product it deems necessary at any time, but keeping the functions and intended use unaltered.
We recommend using 20 rpm gearmotors for doors with vertical movement with conical cable winder drum.
For non-balanced sectional doors we recommend using RDF series gearmotors with parachute device.
When assembling gearmotors with 31.75 mm diameter shaft from the left, the tab is to be blocked only with a shoulder collar
because fixing with a screw could break the shaft.
Only suspended assembly is allowed for “light chain” gearmotors (fig. 4).
TECHNICAL SPECIFICATIONS
ANNUAL CHECK
Information for whoever carries out the checks
Gearmotor:
The mechanism is maintenance-free 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.
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).
