1.1. MAXIMUM DUTY CYCLE CURVE
The curve allows the maximum working time (T) to be
obtained as a function of duty cycle (F).
E.g.: The 620 rapid, 640, 642 R/40 and 642/70 operators can
work continuously with a 100% duty cycle, because they
are equipped with a cooling fan. The 620 standard and
642 std/40 models can work continuously with a 70% duty
cycle.
To ensure good operation, keep to the field of operation
lying below the curve.

Important: The curve refers to a temperature of 24°C.
Exposure to direct sunlight can result in a reduction in duty
cycle to as low as 20%.
Calculating duty cycle
The duty cycle is the percentage of effective working time
(opening + closing) with respect to the total cycle time
(opening + closing + pause times).
It is calculated using the following formula:
Ta + Tc
%F =
Ta + Tc + Tp + Ti
where:
Ta = opening time
Tc = closing time
Tp = pause time
Ti = interval between a complete cycle and the next.

Notes:
1) Use suitable rigid and/or flexible conduits for installation
of the electrical cables.
2) Always route the low voltage accessory connection
cables separately from the 230 V~ power supply cables.
Use separate sheaths to avoid any interference.

4. INSTALLATING THE SYSTEM
4.1. PRELIMINARY CHECKS
For safe, correct operation of the automation system,
make sure that the following requirements are met:
•
During its movement the beam does not strike against
obstacles or overhead power cables.
•
The characteristics of the ground must ensure sufficient
support for the foundation plinth.
•
There must be no pipes or electrical cables in the area
to be dug for installing the foundation plinth.
•
If the housing is located in a vehicle transit area, it is a
good idea to provide protection against accidental
collisions.
•
Check that the housing is provided with an efficient
earth connection.
4.2. INSTALLING THE BASE PLATE
1) Assemble the base plate, as shown in Figure. 6.
2) Prepare a foundation plinth as shown in Fig. 7 (for soft
ground).
