PRODUCT DESCRIPTION AND
INTENDED USE
Era Fit MHT is a family of tubular motors intended exclusively for the automation of
various types of awnings (see fig. 5). Any other use is absolutely prohibited! The
manufacturer is not liable for damage resulting from any use of the product
other than the intended use specified in this manual.
Functional characteristics of the product: • it is powered by the electricity mains; •
it must be installed inside the winding roller; the overhanging face is fastened to the
inside of the box with screws and the appropriate support brackets (not included in
the package); • it has a built-in radio receiver and control unit with encoder technol-
ogy that electronically controls the movement and precision of the limit switches; •
it is compatible with all Nice electronic control components (transmitters and climate
sensors) that use the NRC radio system; • it can be controlled by radio using vari-
ous optional accessories not included in the package (see fig. 3); • it can be pro-
grammed via radio, with a portable transmitter or with a Nice hand-held programmer
(these accessories are not included in the package); • it can move the awning up or
down; stop it at the upper limit switch, the lower limit switch or various intermediate
positions; • it is equipped with a thermal protection system which, in the case of over-
heating caused by overuse of the automation (beyond the indicated limits), automati-
cally cuts off the electricity supply, restoring it as soon as the temperature goes back to
normal; • it is available in several versions, each with a certain motor torque (power).

2.1 - Utilization of the emergency manouvre (and
subsequent automatic realignment)
Era Fit MHT tubular motors have an emergency mechanism. The emergency mech-
anism allows the awning to be moved manually, for instance during a power failure. It
is operated by rotating the rod in the head of the motor in either direction.
When using the emergency mechanism, or if the motor is powered off for more than
24 hours, the motor's control unit loses the current position of the awning. This situa-
tion is resolved by an automatic realignment manoeuvre; one of two commands may
be sent to the motor, to which it responds differently.
– UP command: the motor raises the awning until it reaches the closed limit position.
– DOWN command: the motor lowers the awning for 3 seconds, then reverses until
the awning reaches the closed limit position.
N.B. – The awning is closed with the preselected RDC setting (reduced traction
torque).

INSTALLATION OF THE MOTOR AND
THE ACCESSORIES
3.1 - Preliminary checks before installation and
limitations on use
• Check the condition of the product right after unpacking it.
• This product is available in several versions, each with a specific motor torque.
Each version is designed to drive awnings of a certain size and weight. There-
fore, before installation make sure the product's motor torque, rotation speed and
operation time are suitable for automating your awning (see the "Guide to Selec-
tion" section in the Nice Product Catalogue – www.niceforyou.com). In particular,
do not install the product if its motor torque is greater than that needed to
move your awning.
• Check the diameter of the winding roller. This must be chosen according to the
motor torque, as follows:
– for motors that are size "M" (Ø = 45 mm) and have a torque of up to 35 Nm
(included), the minimum inside diameter of the winding roller must be 52 mm;
– for motors that are size "M" (Ø = 45 mm) and have a torque of up to 35 Nm, the

Fixed arm awning
minimum inside diameter of the winding roller must be 60 mm.
• Before automating an awning, check that there is enough free space in front of it
for it to be completely opened.
• If the motor is to be installed outdoors, adequate protection against atmospheric
agents must be guaranteed.
• The power supply cable for the motor is made from PVC and is suitable for use in
indoor environments. For use in other environments, protect the entire length of the
cable by inserting it inside a dedicated sheath for protecting electrical cables.
Additional limitations on use are contained in chapters 1 and 2 and in the "Technical
characteristics" section.
3.2 - Assembly and installation of the tubular motor
ATTENTION! - Before starting, carefully read the warnings under sections
1.1 and 3.1. Incorrect installation could cause severe physical injury.
To assemble and install the motor, refer to fig. 4. Moreover, consult the Nice product
catalogue or go to www.niceforyou.com to choose the crown of the limit switch (fig.
4-a), the drag wheel (fig. 4-b) and the motor fastening bracket (fig. 4-f). ATTEN-
TION! - Do not apply screws to the winding roller on the section that is crossed by
the motor internally. Such screws could damage the motor.
3.3 - Installation of accessories
After installing the motor, install the accessories, if required. Per In order to identify
those that are compatible and choose the models desired, see the Nice product
catalogue, also viewable at www.niceforyou.com. Fig. 3 shows the type of acces-
sories that are compatible and their connection to the motor (all of these are options
and not included in the package).

ELECTRICAL CONNECTIONS AND
FIRST POWER UP
The electrical connections must be made only after installing the motor and compat-
ible accessories required.
The electrical cord of the motor is made up of the following internal cables (fig. 3):
Cable Colour Connection
1 Brown
Power supply phase
2 Blue Neutral
3 Yellow-green Earth
4.1 - Connection of motor to electricity mains
Utilise cords 1, 2, 3 (fig. 3) to connect the motor to the main and pay attention to
the warnings:
– improper connection can cause breakdowns and hazardous situations;
– scrupulously respect the connections indicated in this manual;
– in the power supply network of the motor you must install a disconnection device
having an opening distance of the contacts that allows complete disconnection
in the overvoltage category III conditions, in conformity with the installation rules
(disconnection device not supplied with the product).
4.2 - Connection of accessories to motor: only
accessories that connect via radio
(portable transmitters and certain climatic sensor models)
Memorise these accessories in the motor during the programming phases; refer to
the procedures given in this manual and those given in the manuals supplied with
the devices.

PROGRAMMING AND ADJUSTMENTS
5.1 - Transmitter to the used for programming
procedures
• The programming procedures can be performed exclusively with a Nice
transmitter having at least the following keys s, n, t.
• The programming procedures must be performed exclusively with a transmitter
memorised in "Mode I" (paragraph 5.5 or 5.9.1).
• If the transmitter used for programming controls multiple automation units, you
must select the "unit" corresponding to the automation you are programming
before sending a command during a procedure.
5.2 - Positions in which the awning stops
automatically
The electronic system that controls the awning movement at all times can automati-
cally stop the movement when the awning reaches a certain position programmed
by the installer. The programmable positions are (fig. 6):
– position "0" = upper limit switch: totally wound awning;
– position "1" = lower limit switch: totally unwound awning;
– position "H" = intermediate position: partially open awning;
– position "Z" = is the point where the awning impact against its structure,
at the end of total closure, when it is not stored no travel limit.
