748-24V AUTOMATION SYSTEM

These instructions apply to the following models:

Operators 748-24V and 724MPS

The FAAC 748-24V automation system for sliding residential gates is an
electromechanical operator that transmits the leaf movement by
means of a pinion coupled to a rack fixed to the gate.
The irreversible system locks mechanically when the motor is not
running, so it is not necessary to install a lock.

1.1. MAXIMUM DUTY CYCLE CURVE

The curve makes it possible to determine the maximum operating time
(T) as a function of the duty cycle (F), e.g., the 748-24V operator can
work continuously at a duty cycle of 70%.
To ensure smooth running, operation should be kept within the duty
area below the curve.
Important: the curve was plotted on the basis of operation at 24 °C.
Allow for up to 20% reduction of duty cycle in case of exposure to
direct sunlight.

Calculating the duty cycle

The duty cycle is the
proportion of the actual
operating time (o
closing) with respect to the
total time of the cycle
(o c pause
time).
The formula for calculating it is
the following:

 

%F= 

        To + Tc           

  x 100

         

 To + Tc + Tp + Ti

where:
To = opening time;
Tc = closing time;
Tp = pause time;
Ti = duration of interval between a complete cycle and the next one.

INSTALLATION OF AUTOMATION SYSTEM

3.1. PRELIMINARY CHECKS

To ensure trouble-free operation, make sure that the gate (whether
existing or yet to be installed) has the following specifications:
• Max. gate weight 400 kg.
• Strong and rigid leaf frame.
• Flat leaf face, with no protruding parts and no vertical members.
• Smooth and even movement of the gate over its entire travel.
• No sideways oscillation of the leaf.
• Upper and lower sliding system in perfect conditions.

The use

of floor tracking with a rounded channel is preferable to reduce
friction in the sliding movement.

• Only two slide wheels.

Mechanical safety stops to avoid risk of derailment. These stops must
be firmly fixed to the ground or to the floor track, about 2 cm beyond
the travel limit.

• No mechanical locks.
If any welding or brazing is required on the gate, it should be done
before installing the automation system.
The condition of the structure directly affects the reliability and safety
of the automation system.

Use suitable rigid/flexible pipes for laying power cables.

•Always keep low voltage accessory cables separate from 230V~ power

cables. To avoid interference, use separate sheaths.
