The curve makes it possible to determine
maximum operating time (T) on the basis of
duty cycle (F).
For example, 760 CBAC/SB operators can
run continuously at a duty cycle of 60%.
To ensure smooth running, operation should
be kept within the area below the duty cycle
curve.
Important Note
:
The curve has been
plotted for operation at 24 °C.
Allow a reduction of up to 20% in the duty
cycle at higher ambient temperatures.
Calculating the Duty Cycle
The duty cycle is the percentage of actual
operating time (opening and closing)
compared with total cycle time (o
cstat internal).

Important Notes:
Read these instructions carefully before installing the gate automation system. Keep these
instructions for future reference.
Installation and electrical wiring must conform to current standards.
Switch off power supply before performing any work on the electronic control unit.
Install a
10 A
thermal-magnetic differential switch with
O.03 A
trip threshold up-line from the
electrical system.
FAAC accepts no responsibility for damage or injury resulting from the incorrect use of this
gate automation system.
