elero folding shutter drive type KL/DMA
General information
Torque switch-off
The drive incorporates an electronic torque switch-off.
The torque at which it switches off can be adjusted over a continuous
range by turning the "T" knob on the circuit board. The torque is
increased by turning in the + direction, and reduced by turning in the
- direction. The factory setting (in the centre) corresponds to the
standard value that suits most cases. After three uninterrupted travel
operations between the stops (opening and closing) the travel is
programmed. The device will automatically learn the end shut-of
points after driving against the stops for the first time. After this,
the drive will automatically switch to a soft switch-off shortly before
reaching the stops.
It is still, however, necessary to have the stops. It is not possible to
operate the drive without fixed stops.
Resetting
It is possible to reset the end shut-of points and/or the soft switch-off
after the system has learnt them.
Important: It is only necessary to reset the drive if structural changes
are made to the track.
Reset procedure
1. Connect the OPEN and CLOSE direction lines to a switch.
2.Close the switch for at least 10 seconds.
3.Reconnect the device for operation.
(See connection example.)
Important: Both drives in a pair can be reset simultaneously by
connecting them in parallel.
Shut-off torque: 15 Nm–25 Nm, over a continuous range.
1 drive is required for each leaf. The electronics permit
multiple drives to be connected together. (Observe the
maximum rating of the power supply.)

Adjusting the start-up delay
The drive operates without delay under the factory setting (rotary
knob in the centre position).
If a rebate profile is fitted to one of the two wings, the rotary "L-R"
knob can be adjusted for a start-up delay for left or right handed
running.
Delay: 0–20 seconds, continuous range

Important! It is important that both drives are adjusted in
accordance with Figure 2. The leaf that does not

Installation instructions and mounting dimensions
elero folding shutter drive type KL/DMA
Mounting dimensions
As a result of different wall thicknesses, both the square drive shaft of
the inside opener and the protective sheath must be adjusted to
match the wall concerned. The following calculation formula can be
used here:
Dimension F of the inside opener = total wall thickness - 196 mm (B)
Important: The minimum dimension for which fitting is possible is
300 mm for flush mounting. 250 – 300 mm is appropriate
for partial surface mounting
.
Sample calculation
The drive is to be fitted into a wall with a total thickness of 300 mm.
Dimension "B“ (196 mm) on the folding shutter drive cannot be
changed.
Dimension " F“ is then 300 mm - 196 mm = 104 mm.
The protective sheath "E“ of the square drive shaft "D“ must be 28 mm
shorter than the drive shaft.
Installation instructions
Ensure when assembling the folding shutter drive that
the weight of the shutter is carried by the upper hinge,
so that the inside opener only has to transmit the
turning moment.
Rigid stops must be attached to the shutters inside
and outside to enable the drive to function correctly.
The stops must be at the same level as the drive.
The drive and the inside opener must be properly
sealed in or bolted to the wall.
Ensure during fitting that the motor and the inside
opener are longitudinally aligned, and that the drive is
pushed all the way onto the inside opener.
elero recommends the inside openers and mountings
manufactured by Kiekert & Nieland.
The cover of the drive closes an
inspection opening, and must
be accessible at all times!

Risk of injury due to electrocution.
The connections to the 230 mains must be made by
authorised specialist personnel.
The regulations of the local energy supply company as
well as the regulations for wet and damp rooms
according to VDE 0100 must be followed when
making the connections.
• The drive must be fixed in such a way that it is not a
danger to personnel.
• The equipment must be completely disconnected
from the power supply before the drive is installed.
• If the folding shutter drive is fitted into other
equipment, the installer must ensure that EMC
guidelines continue to be observed.
•
Please observe the motor's technical data.
• Please observe the appropriate instructions for the
use of controllers and window controllers.
Risk of crushing!
Risk of injury through crushing!
• Make sure that there is nobody in the area where
the folding shutter swings.
• Make sure that it is not possible to operate the
folding shutter when work such as window
cleaning is being carried out nearby.
Note! Make sure that moisture does not enter the
drive.
