General Characteristics
The FAAC 746 Compact Slide Gate Operator uses
GentleSlide
tm
Motion Management
to slide gates with a
pulling force of up to 35 lb (16 kg).
This operator is available in two basic versions, the rack
and pinion or the chain version. It comes as a package
containing the drive unit and factory-wired electronic
control panel inside the top cover of the unit. All
external reversing devices and other accessories must be
ordered separately.
The advanced design of the operator features a small,
self-contained unit composed of an electric motor with a
built-in clutch and a reduction gear box, both housed in a
die-cast aluminum casing. The rack or chain is driven by
the motor to slide the gate.
The FAAC 746 MPS microprocessor control panel is
used with the FAAC 746 Slide Gate Operator. The
control panel operates the slide gate according to the DIP
switch settings you make for the following:
•
Operating logic (choose 1 of 4)
•
Pause time (5 sec to 2 min)
•
5-sec preflashing of an attached warning
light
The control panel provides power for gate accessories of
24 VDC (pulsed or constant). The maximum
recommended amperage draw for accessories should not
exceed 360 milliamps.
An adjustable friction clutch is located on the input side
of the gear box so that when torque exceeds a preset
value, the drive torque on the output shaft remains at a
constant level.
The 746 operator is also equipped with an electronic
speed sensor control device that is designed to help
provide anti-crush protection.
