elero KL/DMA Mounting And Setting Instructions

Mounting and setting instructions
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).

Important! It is important that both drives are adjusted in
accordance with Figure 2. The leaf that does not
have the rebate profile also requires a start-up delay.
