1 Description of the equipment
The recordDFA 127 (Full Power) isacompact, self-monitoring, microprocessor-
controlled swingdooroperator(abbreviated toDFA). Withitsmanyspecialand
additionalfunctions, it issuitableforaverywide application spectrum. The pathof
everydoormovement iscontrolled bythe microprocessor, whichevaluatesthe cur-
rent doorposition, the doorspeed and the finalposition at everyinstant and pre-
ciselycalculatesthe optimummotion. Thismakesthe familiarend-stops, jerky
brakingactions, creep speedsetc. unnecessary. Dependingon the doorwidth, the
correspondingspringrangemust be selected inthe rangeofEN4toEN6(accord-
ingtoEuropean NormEN1154). Safetyisalsoadditionallyincreased bythe useof
aredundant forcelimitation.
Lowenergydrive(LowEnergy)
Inthe parameterisation ofthe LowEnergydoortype, the DFA actsasan automatic
lowenergyoperator. The openingand closingspeedsarelimited and the operator
ismoresensitiveincaseofacollision. The closingaction takesplaceusingspring
forceand reduced kineticenergy. Toprevent unintentionalormaliciousmodifica-
tionstothe program, useraccess tothe parametersisblocked.
The set valuesforthe permitted speedsareindicated inDIN18650-2. Theyare
calculated dependingion the weight ofthe doorleafand the widthofthe door.
1.1 Types of arms, including accessories
The powertransmission fromthe motorisation unit tothe doorleafiscarried out by
aset ofarms. Dependingon the installation situation, the optimalsolution can be
selected fromtwodifferent typesofarms(standardorslide arm). Standardarms
areavailableindifferent lengthsforvariouslinteldepths. Byusingoptionalexten-
sion pieces, so-called adaptors, different lintelheightscan be compensated.
1.2 Accessories and special applications forthe DFA127
5operationalmodescan be remotelyselected withthe externalBDE-D, whichis
availableasaflush-mounted orsurface-mounted model.
Master/ Slave
Inthe Master/ Slaveoperation, twoDFA 127 can be sequentiallycontrolled without
additionalmechanicaldoorlockingsystems.
Not suitableforfireprotection doors!
Extendedoperator casing
The installation ofadditionalsensordevicesispossibleusingan extended operator
casing.
Flexiblecableconnection
Withthe flexiblecableconnection, the wiringofDFAsthat aremounted on the
movingdoorleafcan be carried out inan elegant manner.
