Direction of rotation
Check that the motors are running in the right direction by pressing the Close or Open push buttons
on the control panel (function as deadman control until ”latched” is selected). Transpose the phase
connections of the motor if the direction of rotation does not match the command given. If the motor
stops, and light diode M1 or M2 begins to flash, the load sensor has tripped out. The swing gate drive
arm or barrier/sliding gate drive clutch may now be engaged
Limit positions
Adjust the limit positions. Run the gate and check that the limit positions cut out in the right position. If
the motor stops, and light diode M1 or M2 begins to flash, the load sensor has tripped out. The load
sensor may need to be increased before the limit positions can be adjusted. See load sensor.
Hints for gate use!
It is a good idea to use the load sensor to check that the limit position for closure is correctly adjusted.
When the gate reaches closed position, its pressure against the closing post should be just right.
When the two meet the load increases, and this can be read off. See load sensor.
Load sensor
The load sensor must be properly set to function correctly. It functions by measuring the phase shift
between voltage and current and calculating cos φ for the electric motor. Cos φ at full load for electric
motors is normally about 0.80. A higher value means a higher load. The red light diodes M1 for motor
1 and M2 for motor 2 indicate loads higher than the limit value set. On start it is normal for light diodes
to flash, since there is a particularly high load at the moment of starting. The load sensor is therefore
uncoupled for part of the starting period. This time can be adjusted and may vary, depending on the
weight and size of the gate. If a value higher than 0.80 needs to be set there is presumably something
wrong. Contact DAAB for advice. The type of supply feeding the control panel must be set if the load
sensor is to function.
(C34)Type of supply
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 C34 appears (voltage supply type).
3. Press the ↵ key. The number appears in the display.
4. Check that the right type has been set. 0=3x400V+N, 1=3x230V, 2=single-phase 230V
5. If the right type has not been 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 type being used appears.
0=3x400V+N, 1=3x230V, 2=single-phase 230V.
8. Press the ↵ key. The value is saved.
Checking the phase sequence (applies only to 3x230V without neutral)
When the neutral is missing, the load sensor scans between two phases, and the phase sequence
between them must be correct. This can be checked the next time the load sensor is read.
In the case of a disconnected motor under no load the value should be about 0.20. If the phase
sequence is incorrect, about 0.95 is shown and the sensor trips out. In normal operation the value
varies from 0.30 to 0.70 – if the phase sequence is incorrect, 0.99 is shown and the sensor trips out. If
the value is incorrect, change the phase sequence (see power supply connection).
Reading the current load (C07,C08)
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 C07 appears (load, motor 1).
3. Press the ↵ key. The value appears in the display.
4. Read off the maximum value when the gate is operated and the motor is running.
5. If there are two motors, repeat items 1-4 for motor 2 with C08 (load, motor 2).
