Safety circuit
The safety circuit consists of a safety output, stop keys, limit switches and contactors. If the controls
should reveal any error during autotest, there is an output in the control panel that cuts the voltage to
the contactors. The stop keys are in series with the contactors and cut the voltage to these. There are
limit switches in series to each contactor, which break the circuit when actuated.
Safety buffer monitoring
There are light diodes to indicate when the safety system has been actuated (by coming on). If the
safety system has been actuated previously, the light diode flashes. The light diode goes off the next
time the gate is operated.
Setting number of safety buffers (C40,C41,C42)
It is possible to set the number of safety buffers that are connected to the installation. This is normally
set at the factory by DAAB. Check the setting as follows:
1. Press the ↵ key so that the display shows the channel number (C to extreme left).
2. Step using the + key or the – key until C40 appears (number of buffers KSS1).
3. Press the ↵ key. The number appears in the display.
4. Read off the value, which should normally be 1 if a buffer is connected to KSS1.
5. If the wrong number is set, change the value as in items 6-8.
6. Press the + key. The value starts to flash.
7. Step using the + key or the – key until the value you wish to set appears.
8. Press the ↵ key. The value is saved.
9. Repeat from item 1 but select channel C41 instead (number of buffers, KSS2).
Setting function of safety buffers (C47)
It is possible to choose between stop or stop/reverse function when the buffer is actuated. If the
gate/door is equipped with safety buffers for both opening and closing you can choose between
several combinations for best personal security depending on type of gate or door. See page 22.
Magnetic lock (extra accessory)
When a magnetic lock is used, the magnet must be released, and the residual e.m.f. from the magnet
must be able to dissipate before the gate begins to open. The opening of the gate can therefore be
delayed, by an adjustable time of 0-1.0 sec. If the magnetic lock is of the overlap type, the delay time
for one of the gate halves must be set.
Opening time delay (C39)
Check the setting as follows:
1. Press the ↵ key so that the display shows the channel number (C to extreme left).
2. Step using the + key or the – key until C39 appears (Open time delay).
3. Press the ↵ key. The number appears in the display.
4. Read off the value, which for the DAAB magnetic lock should be 0.5 sec.
5. Correct delay not displayed? Set correct time as in items 6-8.
6. Press the + key. The value starts to flash.
7. Step using the + key or the – key until the value you wish to set appears.
8. Press the ↵ key. The value is saved.
Delay of one gate leaf, for overlap (Slam plate or Electro-magnetic lock)
If there are two gate leaves and one of them overlaps the other, one half can be delayed. Motor 2 is
delayed by the time set when opening, and motor 1 when closing.
Setting delay of one gate half (C38)
1. Press the ↵ key so that the display shows the channel number (C to extreme left).
2. Step using the + key or the – key until C38 appears (motor 2 open time delay)
3. Press the ↵ key. The number appears in the display.
4. Press the + key. The value starts to flash.
5. Step using the + key or the – key until the value you wish to set appears (normally 3 sec).
6. Press the ↵ key. The value is saved.
