Control Units |
Magnetic Autocontrol offers the perfect solution for every barrier type. Control
units with microcontrollers and solid-state outputs guarantee operation without
wear for every application. A lot of options are standardized and can be used in
combination with additional control units.
The MLC (Magnetic Lane Controller) was especially developed as a dedicated
control device for the new generation of barriers MIB 20-30-40 and is based on
the most modern microprocessor technology. Many years of experience have come
together to form the design of the hardware and software.
Tried and tested functions have been borrowed from the well-known MCU and
MUB control devices, which have been extended by the addition of 16 digit
display, two loop detectors and a PC bus interface.
This interface permits communication with the new Magnetic I/O box and
with other interface modules (RS485). The barrier motor itself is driven by
triac end stages, contact-free and completely free of wear. The integrated
universal electronic power supply is of particular advantage as it offers a
voltage range of 100–240 V at 50-60 Hz. A special barrier angle sensor is
mounted on the driven shaft of the barrier motor, which communicates the exact
boom position to the MLC control device. This removes the need for the limit
switches which are normally necessary to communicate the angle of the barrier
boom and for the switches which normally activate the electronic braking
mechanism. The combination of the sensor and braking parameters programmed into
the MLC guarantee the optimum braking characteristics every time for all types
of barrier. It is especially important in the
case of rapid barrier movements that the centrifugal mass is braked before the
end position is reached. This results in substantially less wear to the gears
which guarantees a high mechanical service life. Any bouncing of the barrier
boom in the end position is also excluded. When
the current returns, the control device recognizes the position that the barrier
currently has. Depending on the parameters which have been loaded, the control
device reacts in one of three ways: open, retain position, or close.
