2.5 Installation
(electrical)
Danger!
Risk of electric shock
Electrical installation on site must be carried out by a qualified electrician only.
9
For electrical installation on site observe VDE (German Electrical Engineers Association)
regulations and the requirements of the local mains supplier.
9
Disconnect mains supply before carrying out any work on the installation or the control unit.
Danger!
Caution!
Risk of destroying the motor
The motor requires a 24 V DC connection. Other voltages will destroy the motor.
9
Connect the motor accordingly.
9
Do not lay the motor connecting cable together with a mains wire
9
Never connect 24 V DC drives to 230 V ! Danger of life !
9
Low-voltage lines and power lines must be wired separately.
A two-core (24V) connecting cable is required to connect the motor (see "Technical Data").
9
Follow the electrical connection diagram in section "2.12 Connection diagram “.
9
For cable lengths, cable types and cable cross-sections observe the details in the connection
diagram and the "Technical Data".
9
Make sure that the cables are prevented from being cut, kinked or twisted. If necessary use cable
ducts.
9
Verify the correct terminal assignment, the supply voltage (see type label) and the minimum and
maximum ratings (see technical data). Carefully adhere to all assembly details given.
The drive requires a voltage of 24 V DC (direct current). The 24 V DC variant requires a class II mains
adapter to transform the supply voltage (230 V~, 50 Hz or other) to 24 V DC; the technical specifica-
tion of the adapter must correspond to the parameters indicated on the type label.
2.6 Operation
/
Control
The fixing brackets vary depending on the mounting method (sash mounting or frame mounting). The
appropriate assembly instructions are included in the bracket set each.
Assembly order
•
Install and connect the drive according to the assembly instructions (24V DC)
•
Ensure the drive closes the sash completely.
Adjustment on tilt window
For an optimum chain run on a tilt window, the locking screw is turned in clockwise. The factory-preset
projection of the locking screw is 3.5 mm which corresponds to maximum chain tension. The tension is
reduced by turning the screw clockwise (max. 5 mm = 7 revolutions).
22
Caution!
Do not change the factory setting for top hung windows!
Mind load-displacement diagram and chain rigidity when installing the drive
The drive must not be assembled without observing the load-displacement diagram. It is important that
in sloped or vertical position the chain should resume its rigidity on its own. Recommendation: Always
mount the drive with the motor side (exit of connection cable) at the top.
Mechanical unlocking of chain
The chain can be unlocked mechanically by means of a special key.
Verify the CLOSED position as soon as the chain is unlocked.
Caution!
The drive features electronic travel detection. If the chain has been unlocked and moved by hand, it
is necessary to verify during start-up that it travels up to a distance of approx. 40 mm to CLOSED
position before finishing the closing action in soft run mode.
If the chain does not move as far as the soft run mode, unlock it with the key and pull it out by hand.
Then start the electrical close run. If the soft run mode starts too early now, this will be detected by
the drive electronics and automatically adjusted at the next run from CLOSED to OPEN.
