Product Description And Intended Use; Limits Of Use - Nice Ten TN2010 Instrucciones Y Advertencias Para El Instalador

2) Product description and intended use

TEN (figure 1) is a gearmotor for the automation of counterweight up-and-over doors, spring up-and-over doors, projecting, non- projecting,
and articulated. TEN is fitted with an electronic limit switch system with absolute encoder to enable constant detection of the motor position,
even when the door is released for manual manoeuvres. It is able to reach the travel limit (opening and closing) through a deceleration phase.
It also ensures constant control of the force required during manoeuvres, detecting any anomalies, such as a sudden obstacle that blocks
leaf movement; in this case the automation executes a stop with brief inversion of movement.

Model DESCRIPTION
TN2010 Irreversible gearmotor, control unit, electronic limit switch via absolute encoder and courtesy light.
TN2020 Irreversible gearmotor and courtesy light. To be used as "Slave" of TN2010 or TN2020
* If used in other configurations, ensure that the power supply is from a very low voltage safety system in which voltages never exceed the established
low voltage safety limits.

Before proceeding with installation, check the condition of the product com-
ponents, suitability of the selected model and conditions of the intended instal-
lation environment.

2.1) Limits of use

Data related to the performance of TEN are provided in chapter "8 Technical specifications" and are the only values that enable correct eval-
uation of the suitability of application. In general TEN can automate up-and-over doors within the limits stated in Table 2.

Door type
Projecting up-and-over door
Non-projecting up-and-over door
The measurements in table 2 are guideline only for general estimate purposes. The effective suitability of TEN for automation of a specific door
depends on the degree of leaf balancing, friction on tracks and other factors, also occasional, such as wind pressure or the presence of ice,
which may obstruct leaf movement. To ensure feasibility, it is absolutely indispensable to measure the force required to move the door through-
out travel and to check that this never exceeds the "nominal torque" as specified in Chapter "8 Technical specifications"; it is also important to
establish the number of cycles per hour and consecutive cycles admissible, with reference to Table 3 and Table 4

Force required to move leaf (N)
Up to 120

To avoid overheating, the control unit is equipped with a limiter based on the force and duration of the cycles, inter-
vening when the maximum limit is exceeded.
