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)
must be installed.
The manual activation devices (release and chain drive) are
designed for installation at a height of up to 4 metres. To install at
greater heights, use the extension kits (optional items).
The operator is equipped with four microswitches with the
following functions:
•Opening limit-switch
•Closing limit-switch
•Winch safety switch (only on models supplied with the manual
manoeuvring system)
•Release control safety switch
The supplied support plate will enable you to secure the operator
at a maximum distance of 125mm between the anchoring point
(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
operations during the preliminary stages of installation.
5.1 OPERATOR WORK POSITION
The operator - supplied with a chain-operated manual motion
device - must be installed in the position shown in figure 5. In the
absence of the winch, the operator can be installed in any
position.
If you wish to install the remote release control, first check that
the release lever does not interfere with the operator’s external
parts.
The securing plate can be installed on any of the operator’s
two sides.
5.2.1 IDENTIFYING ROTATION DIRECTION (540 operator with 200BT
equipment)
Remove the cover of the limit-switch unit.
Figure 6 shows rotation directions Dir1 and Dir2, activated by
commands IN1 and IN2 (see figure 15), and the position of limit-
switches FC1 and FC2.
The motion controlled by IN1 is stopped by FC1 and the motion
controlled by IN2 is stopped by FC2. Consequently, if, for example,
Dir2 is the rotation direction causing the door to close, IN2 is the
input of the closing command, IN1 is the input of the opening
command, FC2 determines the closing stop point, and FC1
determines the 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)
Remove the cover of the limit-switch unit.
Figure 6 shows rotation directions Dir1 and Dir2. Motion in Dir1
direction is stopped by FC1 and motion in Dir2 direction by FC2.
Consequently, if, for example, Dir2 is the rotation direction causing
the door to close, FC2 determines the stop closing point and FC1
determines the opening stop point.
The closing stop point can be corrected also by varying the
post-travel limit deceleration parameter on the 578D equipment.
The OPEN command is normally associated with Dir1 motion -
consult the equipment instructions if the rotation directions have
to be reversed.
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
connection to the operator.
