- maximum weight 250 kg.
- opening angle up to 120°
The shape of the gate and weather conditions (such as the presence of
strong winds) may reduce these maximum values; in this case the user
must measure the torque required to move the leafs in the worst condi -
tions, and compare this value with the technical specifications.
2 - Check the overall dimensions of the gearmotor ( fig. 2 ). Note – These
measurements also serve as a reference to calculate the space occu -
pied by the foundation pit for routing the electrical cable ducting.

- Ensure that the estimated lifetime is compatible with the intended use
(see paragraph 3.3).
4 - Ensure that all limitations, conditions and warnings in this manual can
be fully observed.
3.3 - PRODUCT DURABILITY
The lifetime is the average economic duration of the product. The value of
lifetime is strongly influenced by the intensity of the manoeuvres, i.e. the
sum of all factors that contribute to product wear, see Table 1. To esti -
mate the durability of your automation, proceed as follows:
01. Add up all the values in the items of Table 1 ;
02. In Graph 1 from the value obtained above, trace vertical line until
it intersects the curve; from this point trace a horizontal line until it
intersects the line of the “manoeuvre cycles”. The value obtained is
the estimated lifetime of your product.
The lifetime values specified in the graph are only obtainable if the mainte -
nance schedule is strictly observed (see chapter 9 - Maintenance sched -
ule). The estimation of lifetime is made on the basis of design calculations
and the results of tests performed on prototypes. As it is only an estima-
tion, it does not represent any form of guarantee on the effective lifetime
of the product.
Example of durability calculation: automation of a gate with a leaf length of
1.5 m with weight of 220 kg, for example, in a location subject to strong
winds. Table 1 states the “severity index” values for this type of installa -
tion: 10% (“Leaf length”), 25% (“Leaf weight”) e 15% (“Installation in windy
areas”).
These values must be added up to obtain the overall severity index, which
in this case is 50%.
With the value obtained (50%), check the horizontal axis of Graph 2
(“severity index”), for the corresponding value of “manoeuvre cycles”
which our product can complete in its lifetime = approx. 55,000 cycles.
Connection of the control unit with the various devices is by means of
a single 2-wire cable (“ECSbus” system). The control unit can also be
mains-powered (230 V) or alternatively by the Mhouse PF photovoltaic
system.
If powered from the mains, it can house a buffer battery (model PR1,
optional accessory), which ensures that the automation can perform a
number of manoeuvres for several hours in the event of a power failure.
During the power failure, or at any other time, the gate leaf can be moved
manually if required, by first releasing the gearmotor using the relative key
(see chapter 11.3 - User’s Guide).

may not be present in the kit. .For a complete description, refer to the
Mhouse product catalogue or visit the website www.niceforyou.com.
- The limit switch stops are not supplied in the pack and are not part of
the Mhouse product range.

3.1 - CHECKING SUITABILITY OF GATE TO BE
AUTOMATED AND RELATIVE ENVIRONMENT
• Ensure that the mechanical structure of the gate complies with current
national standards and that it is suitable for automation. For this check,
refer to the information specified on the gate dataplate. Important -
This product cannot be used to automate a gate that is not already effi -
cient and safe; furthermore it cannot solve defects caused by incorrect
gate installation or poor maintenance .
• Manually move the gate leafs in both directions (opening/closing) and
ensure that friction is constant throughout travel (there must be no
points of increased or decreased force).
• If the leaf is fitted in a pedestrian pass door or a door onto the leaf
movement area, ensure that this door does not obstruct normal travel,
and install a suitable interlock device if necessary.
• Manually move the gate to any position; leave it stationary and ensure
that it does not move when left.
• Ensure that the space around the site of gearmotor installation enables
safe and easy manual gate release.
• Ensure that the selected surfaces for installation of the various devices
are solid and guarantee a stable fixture; as regards photocells, select a
flat surface that guarantees correct alignment between photocells (Tx
and Rx).
• Ensure that all devices to be installed are in a sheltered location and
protected against the risk of accidental impact.
• Verify the overall limits with reference to
fig. 2
.
• Ensure that there is sufficient space also when the gate is open ( fig. 3 ).
• On the basis of the leaf opening angle, check to ensure observance of
the positions in fig. 4 and Graph 2 ( fig. 5 ).
• The bracket can be fitted in various ways (
fig. 10
): position “C” can vary
from 53 mm to 176 mm. It is normally approx. 150 mm.
• Position “D” is easily measured on the gate.
• Position “A” is the sum of “C” and “D”.
• On the basis of value “A”, and the leaf opening angle in the table, value
“B” can be calculated. For example: if “A” is 150 mm and the leaf open -
ing angle is 115°, the value of “B” is approx. 160 mm.
It is recommended to select similar values for “A” and “B”. This
guarantees regular movement of the leaf and minimal stress on
the gearmotor.
3.2 - PRODUCT APPLICATION LIMIT
Before proceeding with installation, perform the following checks in the
specified sequence and ensure conformity both with the data in this para -
graph and the technical data provided in the chapter “Technical Specifi -
