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
1.2. 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
(o closing) compared to total time of cycle (o
c pause times).
Calculation formula:
%F =
______________________
Ta + Tc
Ta + Tc + Tp + Ti
X 100
where:
Ta = opening time
Tc = closing time
Tp = pause time
Ti = time of interval between two complete cycles
