These instructions apply to the following models: AT-2500
The automatisms AT-2500 gearmotor is an
electro-mechanical operator designed for moving sliding
gates.
The non-reversing reduction system ensures the gate is
mechanically locked when the gearmotor is not operating,
therefore it is not necessary to install any electric lock
A convenient manual release with customised key makes it
possible to move the gate in the event of a power failure or
malfunction of the operator.
The AT-2500 gearmotor was designed and built
for controlling vehicle access.
AVOID ANY OTHER USE WHATEVER.
1. DESCRIPTION AND TECHNICAL SPECIFICATIONS
1.1. DIMENSIONS AT-2500
1.2. MAXIMUM USE CURVE
The curve makes it possible to establish maximum work time
(T) according to use frequency (F). With reference to IEC 34-1
Standard, the AT-2500 gearmotor can operate at a use
frequency of 40%.
To ensure efficient operation, it is necessary to operate in the
work range below the curve.
Important: The curve is obtained at a temperature of 20°C.
Exposure to the direct sun rays can reduce use frequency
down to 20%.
Calculation of use frequency
Use frequency is the percentage of effective work time
(opening + closing) compared to total time of cycle (opening +
closing + pause times).
Calculation formula:
Ta + Tc
______________________
%F =
Ta + Tc + Tp + Ti
MOTOR AT 2500
where:
Ta = opening time
Tc = closing time
Tp = pause time
Ti = time of interval between two complete cycles
