If the door hits an obstacle during closing and is switched off by the automatic
obstacle detection or if the door is switched off during closing via a contact
strip on the secondary closing edge, the door reverses, then stops and does not
move again until the next command via pushbutton, key switch or similar.
If the door is switched off in the inlet via a light barrier or contact strip at the
main closing edge, the door reverses and moves to the OPEN limit switch. After
the hold-open time has elapsed, a closing attempt is made again.

Make sure that dip switches 7 and 8 are set to OFF. Move the gate to the
CLOSED end position. Now move the gate to the desired partial opening posi-
tion by pulse (terminals 8 and 9 of the terminal strip) or pulse button on the
control unit or by radio. Move dip switch 4 to the ON position, the partial
opening is taught-in. Now connect corresponding command transmitters
(pushbuttons, key switches, coding switches, etc.) potential-free as closing con-
tacts to the terminals 9 + 10 (partial opening) of the terminal strip. Optionally,
the partial opening can also be activated with the second button of the hand-
held transmitter. To do this, press the FUNK button on the motor control for
approx. half a second, then press the IMPULSE button for approx. half a sec-
ond. The yellow LED now flashes twice at intervals of approximately two sec-
onds. Now press the desired transmitter key until the flashing of the LED be-
comes a continuous light. The transmitter is now programmed.
A partial opening command in gate position CLOSED always causes a run to the
partial opening position. The next IMPULSE command always causes a closing
command. If the gate is outside the CLOSED end position, the partial opening
command has no effect. If the inputs pulse and partial opening are actuated at
the same time, an emergency stop occurs.

The motor control 47-21-11A-W of the drive is equipped with a relay for a
warning light. You can connect an external warning light directly to terminals 4
+ 5. A light with 230 V AC must be connected.
Set dip switch 5 to ON for this operating mode. After giving the command, 230
V are directly present, after approx. 5 seconds the drive starts running. The
lamp is activated until the end position is reached. If another command is given
during the 5 seconds prewarning time, the prewarning is terminated and no
gate run is executed. A further command starts the process from the beginning.
