Underground drive unit BF-760
The BF-760 automation system for swing gates is a monoblock
hydraulic unit. It is designed for underground installation and does
not therefore alter the appearance of the gate.
The leaf supporting foundation box comes ready to take an
operator.

1.1 Maximum duty cycle curve (Fig. 2)
The curve makes it possible to determine the maximum operating
time (T) on the basis of duty cycle (F).
Example:
The BF-760 drive unit 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.
Attention:
The curve has been plotted for operation at 24 °C.
Allow a reduction of up to 20 % in the duty cycle if
the system has to operate in direct sunlight.
Calculating the duty cycle:
The duty cycle is the percentage of actual operating time (opening
+ closing) compared with total cycle time (opening + closing +
pause time).
In practice:
TA = opening time
TC = closing time
TP = pause time
TI = time between one complete cycle and the next
2 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.
Warning:
Switch off power supply before performing any
work on the electronic control unit.
Install a 10 A thermal-magnetic differential switch
with 0,03 A trip threshold up-line from the electrical
system.
The manufacturer accepts no responsibility for damage or injury
resulting from the incorrect use of this gate automation system.
Read the leaflet provided with the system for further information,
and make sure that it is passed on to the end user.
