The MLC Control device

The MLC (Magnetic Lane Controller) wasespecially developed as a dedicated controldevice for the new generation of barriersMIB 20-30-40 and is based on the mostmodern microprocessor technology. Manyyears of experience have come together toform the design of the hardware and soft-w a r e .Tried and tested functions have been borro-wed from the well-known MCU and MUBcontrol devices, which have been extendedby the addition of 16 digit display, two loopdetectors and a PC bus interface.This interface permits communication withthe new Magnetic I/O box and with other in-terface modules (RS485).The barrier motor itself is driven by triac endstages, contact-free and completely free ofw e a r .The integrated universal electronic powersupply is of particular advantage as it offersa voltage range of 100–240 V at 50-60 Hz.A special barrier angle sensor is mountedon the driven shaft of the barrier motor,which communicates the exact boomposition to the MLC control device. This re-moves the need for the limit switches whichare normally necessary to communicate theangle of the barrier boom and for the swit-ches which normally activate the electronicbraking mechanism. The combination of the

sensor and braking parameters programmedinto the MLC guarantee the optimum bra-king characteristics every time for all typesof barrier.It is especially important in the case of rapidbarrier movements that the centrifugal massis braked before the end position isreached. This results in substantially lesswear to the gears which guarantees a highmechanical service life. Any bouncing of thebarrier boom in the end position is also ex-c l u d e d .When the current returns, the control devicerecognises the position that the barrier cur-rently has. Depending on the parameterswhich have been loaded, the control devicereacts in one of three ways: open, retain po-sition, or close.A large number of customer suggestionshave been integrated in the basic softwarePLC 100S-xxxxx.• max. 2 loop detectors• direction recognition, park difference

Technical System

The control unit is built into a plastic box. Thetwo removable terminal strips allow a simpleand quick mounting or disassembly of theunit. The housing is clipped directly onto anormed rail.The 16 digit display is clear and easy to read.With the rotary switch and two input keys,the control unit can be easily reprogrammed.

S o f t w a r e

The basic software package with the PLC100S-X0000 parameter set offers a greatrange of programming possibilities. Thefollowing functions and variables can beselected and changed very simply using therotary switch and the two keys: • l a n g u a g e• barrier type• MUB only function (spare)• self-learning mode – reference swing• operating mode 1–8• loop disconnection via the boom angle

( s a f e t y )• duration of open phase• torque period• loop active yes/no• loop function• loop sensitivity• relay switching function• default set

User instructions are given in the display inthe desired language.

To aid servicing, the following informationcan be displayed:• number of barrier opening cycles• service hour counter• error diagnosis

Extended functions are available from us.These parameter sets are either suppliedfactory-programmed or as compact para-meter ‘smart cards’. The new parameterscan be loaded into the MLC control unitvia the PC bus without having to open thedevice. The great advantage of this is thatonly one control unit equipped with thebasic software is needed for all functions.This keeps the costs arising from keepingspare parts to a minimum.

D e t e c t o r

Depending on the parameter set in use, up totwo induction loops can be connected tothe MLC control unit. The loop sensitivity isadjustable over ten steps per detector chan-n e l .The loop frequency of the selected channelis shown in the display in Hz. The loopfunctions can be selected from: • o f f• s a f e t y• p r e s e n c e• o p e n• impulse service• constant service

If the MLC is to be used as a replacement foran MUB, this can be selected via the mainmenu. The MLC will then be 100% com-patible with the original MUB-100.

I n p u t s

The 5 opto-decoupled inputs fulfil the fol-lowing functions using the standard para-meter set:Input 1 = external openInput 2 = open high-rankedInput 3 = external closeInput 4 = no functionInput 5 = photoelectric barrier

O u t p u t s

Two open collector outputs (24V DC) foropen/closed status information have the pur-pose of controlling the external Magneticcontrol panel.Output 1 = barrier openOutput 2 = barrier closed

Center-zero multifunctional relay

Maximum load = 250V AC / 3A.Relay 1 = open sliding door or detectorfunction channel ARelay 2 = counting impulse or detectorfunction channel B

Further functions are available for all inputsand outputs from additional PLC1005-xxxxxparameter sets.

Parameter Set

The desired basic parameters are activatedwithin the parameter set, which at the sametime determines the function of the controlunit. The parameter sets can also be suppliedin smart cards.

E x t e n s i o n s

If the number of inputs and outputs is insuf-ficient for complex applications, the Magne-tic I/O box can be connected via a flat bandcable. This box is always needed for the parkdifference counting function.The external Magnetic control panel withmanual control and the open/closed statusdisplay can also be connected to the MLC.
