5. INSTALLING THE OPERATOR
To work under safe conditions, we advise you to install the
operator while keeping the door fully closed and to read the
whole of this chapter before starting to install.
The 540 operator has a 25.4 mm (1”) power take-off.If the drive
shaft is of a different size,the chain transmission (optional item)
mustbe installed.
The manual activation devices (release and chain drive) are
designedfor installation at a height of up to 4metres.Toinstall at
greaterheights, use the extension kits (optional items).
The operator is equipped with four microswitches with the
followingfunctions:
•Openinglimit-switch
•Closinglimit-switch
•Winchsafetyswitch (only on models suppliedwith the manual
manoeuvringsystem)
•Releasecontrol safety switch
Thesuppliedsupport platewillenableyou to securetheoperator
atamaximum distance of 125mmbetweentheanchoringpoint
(wall or metal structure) and the power take-off axis.
Before installing, we advise you to check the rotation direction
of the power take-off (see paragraphs 5.2.1 and 5.2.2).
For all matters referring to the electrical system, please consult
the chapter entitled“Warnings for the installer”and chapters 3
and 6 of these instructions.
The supplied Cordura handle can be installed, using the plate
fastening points, on the operator, to facilitate the shifting
operationsduring the preliminary stages of installation.
5.1 OPERATOR WORK POSITION
The operator - supplied with a chain-operated manual motion
device-must be installed in thepositionshown in figure 5. Inthe
absence of the winch, the operator can be installed in any
position.
If you wish to install the remote release control, first check that
therelease lever does notinterfere with the operator’sexternal
parts.
The securing plate can be installed on any of the operator’s
twosides.
5.2.1 IDENTIFYING ROTATION DIRECTION (540 operator with 200BT
equipment)
Removethe cover of thelimit-switch unit.
Figure 6 shows rotation directions Dir1 and Dir2, activated by
commandsIN1 and IN2 (seefigure 15), and theposition of limit-
switchesFC1 and FC2.
Themotion controlled by IN1 is stopped by FC1 and the motion
controlledbyIN2 isstoppedbyFC2.Consequently,if,forexample,
Dir2is the rotation direction causing the door to close, IN2is the
input of the closing command, IN1 is the input of the opening
command, FC2 determines the closing stop point, and FC1
determinesthe opening stop point.
The stop spring of the ring-nuts activating the limit-switches, is
kept lifted up by the square - the latter must not be removed
until the door stop points are adjusted.
5.2.2 IDENTIFYING ROTATION DIRECTION (operator with 578D
equipment)
Removethe cover of the limit-switch unit.
Figure 6 shows rotation directions Dir1 and Dir2. Motion in Dir1
directionis stopped by FC1 andmotion in Dir2 directionby FC2.
Consequently,if,forexample,Dir2is the rotationdirectioncausing
thedoortoclose, FC2 determines thestopclosingpointandFC1
determinesthe opening stop point.
The closing stop point can be corrected also by varying the
post-travellimitdeceleration parameteronthe578D equipment.
The OPEN command is normally associated with Dir1 motion -
consulttheequipmentinstructionsiftherotationdirectionshave
tobereversed.
The stop spring of the ring-nuts activating the limit-switches, is
kept lifted up by the square - the latter must not be removed
until the door stop points are adjusted.
Check if an efficient earthing system is available for electrical
connectiontotheoperator.

•Re-install the operator with the plate released.
•Secure the plate to the support, tighten the fastening screws
on the operator to a maximum torque of 18Nm and insert the
secondkeysecuring bush.
•Secure the two bushes after positioning them in contact with
theoperator’spowertake-off.
•Locktheoperator.
If you wish to weld the securing plate to the support, do the
welding with the operator uninstalled, and protect the drive
shaft in the power take-off engagement zone.If the operator
cannot be removed, it must be protected.

5.4 WINCH ADJUSTMENT
Fullyunwind the supplied chainand unite one ofits ends to the
one already inserted in the winch, using one of the supplied
chainlinks (see figure8.).
Cut the chain to measure, preventing the lower part of the
“chain- loop”from touching the ground (see figure 9) and
assemble the other two ends of the chains.
Cut the service tie.
Adjustthe screw of the balancing spring (see figure 10) so that
the winch support completely disappears inside the plastic
enclosure(seefigure11).
Make sure that the traction of just one of the chain branches
causes the winch to engage, and return to idle position on
beingreleased.

is not prevented or interrupted by the tripping of the winch’s
safetymicroswitch.
We advise you to create an anchoring point for the lower part
of the chain so that the chain cannot interfere with transit of
persons or operational means, and fix the sticker showing the
openingand closing directions, so that it isclearly visible.
If using the chain extension kit, replace the balancing spring
(fig.10ref.3)withtheoneinthekit.Furthermore,weadviseyouto
gluetogether the chainlinks during assembly(see fig.8).
5.5 INSTALLING THE REMOTE RELEASE LEVER
Carryout the operations with the door closed.

DESCRIPTION
The 540 and 541 automated systems are ideal for activating
balancedindustrialsectional doors.
Theyconsistof anelectro-mechanicaloperatorand on-boardor
remote electronic control equipment. The non-reversing system
ensures mechanical locking of the door when the motor is not
operatingand, therefore,nolockneeds tobeinstalled.Operator
release and a manual manoeuvring system (the latter is only
supplied on the models for which it is specified), make the door
manoeuvrableinthe eventofapower cutormalfunction.
The door is normally closed; when opening is commanded, the
equipment activates the electric motor which drives the door to
opening position to permit access. In “dead-man”systems, the
commandpush-buttonmustbekeptpressedforthewholeduration

•Astoppulse (ifsupplied)alwaysstopsmovement.
For full details on the behaviour of the automated system in the
differentlogics,consultthe installationTechnician.
Automatedsystemsmay includesafetydevices(sensitive edges,
photocells) that prevent the door from closing and/or opening
when there is an obstacle in the area they protect. Emergency
manualopening ispossiblebyusingthe releasesystem.
Manual command is possible by activating the chain-operated
winch(formodels withwhichitissupplied).
Electric command is disabled during the manual manoeuvre or
whenthe operatorisreleased.
Thewarning-light,wheresupplied,indicatesthatthedooriscurrently
moving.
MANUAL OPERATION (540 and 541 with winch)
If the door has to be activated and the automated system is
inactiveduetoapower-cutormalfunction,thedooropeningand
closing manoeuvres can be done by hand, by using the chain-
operatedwinch. Checktheindicatorsign toseewhichbranchof

andobjects intheimmediatevicinityof theoperatorisabsolutely
forbidden.
If the door has to be moved manually due to a power cut or
malfunctionoftheautomatedsystem,cutoutpowertothesystem
and use the release device as follows: release the operator by
pulling the rope with the red knob (see figure 1) downward until
the lever reaches the travel-limit stop. To restore automatic
operation, fully close the door and pull the rope with the green
