5. FUNCTIONALITY OF REMOTE CONTROL
The upper button on the remote control is normally for the UP direction
(open). The lower button on the remote control is normally for the DOWN
direction (close). The middle button stops the shutter in any position as
required (stop).
If, during an upward or downward movement, the button for the reverse
direction is pressed, the motor automatically changes the direction of
travel.

Battery: „23A", 12Volt,
Partnumber: 10A14
WALL BRACKET (HOLDER):
Supplied as standard with each 1-channel and 6-channel remote control
(without screws and rawlplugs).
Caution! Make sure no electric cables are damaged when fitting the
bracket, particularly when installation is to occur near light switches or
power sockets. The installation site should examined carefully
beforehand.
PROGRAMMING RADIO REMOTE CONTROLS (HAND-HELD
TRANSMITTERS)
Up to 40x remote controls can be memorised. The first remote control
programmed is also called the "master" remote control.
PROGRAMMING A NEW, ADDITIONAL REMOTE CONTROL
(not the first one or so-called master)
PLEASE NOTE: The following steps must be executed quickly.
Read through all the steps first. The easiest way is for a second person
to help by reading out the text while the other person presses the
buttons.
Step 1: The shutter should not be located at its limit.
Via the master remote control:
Step 2: Press and hold the STOP button. The drive turns 2x briefly as a
signal indicating that the command has been understood
(approx. 5 seconds). Wait until the drive stops moving!
Step 3: Then press the UP button (upper button) and also the DOWN
button (lower button) immediately and briefly. Once again the
drive moves 2x briefly as a signal that the command has been
understood.
Via the new remote control:
Step 4: Press and hold the UP button (upper button) on the new remote
control immediately. Once again the drive moves 2x briefly as a
signal that the command has been understood.
• End of process
IMPORTANT NOTES
Note 1: Between Step 2 and Step 3 only max. 2 seconds are allowed as
otherwise the process will be stopped. However, the drive must
have halted beforehand.
Note 2: Between Step 3 and Step 4 only max. 7 seconds are allowed.
Note 3: Don't press a new button before the LED on the remote control
has gone out and the drive has stopped moving. Should the
drive run in one direction for a long time rather than a short time
(between Step 2 and Step 3), the process hasn't worked. Start
again from the beginning.
DELETING REMOTE CONTROLS
An individual remote control cannot be deleted. All remote controls are
deleted together. Deletion is possible:
A. via the "master" remote control
B. directly via the drive (if the remote control has been lost or the battery
is flat)
A. Deletion via the "master" remote control
• Disconnect the power supply to the drive (at least 10 seconds)
• Press and hold the STOP button on the "master" remote control
• Re-connect the power supply now, wait and keep pressing and holding
the button.
After approx. 15 seconds the drive should turn briefly as a signal that it
has understood the command.
• End of process
B. Deletion "without" remote control directly via the drive
• Disconnect power supply to drive
• Connect the free black cable coming from the drive to the (L) cable.
• Re-connect power supply now and wait. The drive should turn 2x briefly
and then run to one of the limit switches as a signal that the command
has been understood. As soon as the drive starts turning, the remote
controls are deleted.
• Disconnect power supply to drive again.
• Disconnect link to black cable making sure the free end cannot cause a
short circuit.
• For further steps, see "Programming the first remote control".
• End of process
PROGRAMMING THE FIRST REMOTE CONTROL
REVERSING DIRECTION OF MOVEMENT
The first remote control is the "master" remote control. It also determines
the direction of movement and decides whether the upper button is
actually responsible for UP functionality or the opposite. Even if all that
needs to be programmed is a reversal of direction of movement, all
remote controls that have been programmed must still be deleted first
(see Deleting with and without remote control).
PLEASE NOTE: If the reason for reprogramming was that the buttons on
the remote control worked the wrong way round (DOWN/UP), press the
DOWN button in the following (only applies to new drives with default
programming).
• Disconnect drive from power supply
• Press and hold UP button or DOWN button (direction of movement) on
the new "master" remote control (stay within radio range of drive)
• Re-connect power supply and wait
• If it has worked, the drive turns 2x briefly as a signal that the command
has been understood.
• End of process
Please note:
• If the process doesn't work, it could perhaps be that a "master" remote
control has already been programmed. Should this not be identifiable
however, everything will first have to be deleted via "Deletion without
remote control".
• Were you within the reception range of the motor?
• Is the battery in the remote control in order?
• Was the period between the connection of the power supply and
pressing the button on the remote control longer than 20 seconds?
ANTENNA:
The cable antenna (see Motor connection) must be accommodated in
the shutter box such that is not wound up together with the shutter. Do
not wind the cable antenna around the power line (range of remote
control is reduced).
CONNECTING A WALL SWITCH (CABLE)
See drawing of motor connection for electrical connection details. A wall
switch can be connected via the black cable. No special shutter switch is
required for this purpose. A standard, 1-pole selector switch often used
for stairways (automatic reset) is adequate. These are widely available in
all shapes and sizes.
Function: The first switch pulse starts the drive, the second stops it.
The next pulse then starts the drive in the other direction, etc.
