INITIAL OPERATION AND TRANSFER
• Connect up the control unit including the safety inputs
• Connect up the gate and lock the motors
• Connect the control unit to the mains
• Check whether any of the LEDs of the safety module have
lit up; this indicates that the control unit has been blocked
because one of the safety devices has been triggered
• Have the limit switches been jumpered? (This should be
done in the factory for 14A and 15A, and for 14B and 15B.)
• Using a screwdriver, adjust the force of potentiometers M1
and M2 (middle left) initially to about 30-50%, depending on
the size and weight of the gate
• Adjust potentiometer P1 to 50% (time adjustment).
• Set potentiometers P2 and P3 to left-hand stop
• Are the end stops in the Open and Closed directions fixed
(present).
• Now push the test button on the control unit; both doors of
the gate should open
• If only one door opens, the other must have been
connected up wrongly.
• Make any fine adjustments that may be necessary
• Check the operation of all safety devices
• Connect the receiver, and "teach" the transmitter how to
work with the system.
• Instruct the personnel who will be operating the system
• Complete the transfer form
INITIAL SETTING OF REMOTE CONTROL
The PTT-approved, charge-free radio remote control unit
functions with a computer pre-programmed private
security code. In this way, your swing gate control unit can
only be activated by handset with the correct code. The
operating range depends on local conditions.
The receiver module of the motor control unit has a built-in
self-learn function. It can be set in accordance with the pre-
programmed code of the handset by pressing the learn
button (Illustration 7).
The control unit comprises 2 learn channels. In this way, the
handset may be used to open or close one gate only or both
gates simultaneously. When, for example, channel 1 (1)
receives the remote control code of the first control button of
the handset, then only one gate is opened.(4.1) When the
second channel (2) is set in accordance with the remote
control code of the second control button, then both gates are
operated when this button is pressed (5.2).
In order to configure the control PCB pre-programmed code in
accordance with the handset, the learn and transmit buttons
for the required channel must be pressed and held until the
associated LED lights up briefly. When a multi-control handset
is used, this procedure must be repeated for each control
button and associated learn channel.
Repeat this procedure for every transmitter.
ANTENNE: An antenna is connected to the radio reception
module. If a longer range is required, connect an external
antenna (ANT4X-1LM) (Illustration 7).

DELETION OF PROGRAMMED
REMOTE-CONTROL CODES
Press the corresponding learn button (1 or 2) approx. 10 sec.
on the receiver PCB until the learn LED goes off. The code
memorised with this learn button has now been deleted.
REPROGRAMMING
When reprogramming, the above-mentioned coding steps must
be repeated for all remote-control handsets in operation and
their control buttons. The operating range of the remote-control
unit depends on local conditions. Press and hold the button on
the handset (approx. 2 seconds) until the gate begins to move.
In the PTT-approved frequency range for the radio control of
gates, there are also medical, industrial, scientific, military and
household radio systems in operation, some of which have a
very high transmission range. The close proximity of such a
radio installation could lead to a reduction in operating range or
temporary interference in your radio remote-control system.
