B. Selection of dim principle ‘mode’
The correct dim principle can be selected automatically or manually. As a result, there are three
possible mode settings on the dimmer: automatic, manual reverse phase control and manual
phase control.
As a standard, the dimmer is set to automatic mode. In automatic mode, the dimmer selects
between phase control and reversed phase control. To this end, a ‘load test’ will be performed
for max. 2s. If the ‘error indication’ LEDs (see fig.1) light after 5s., there is either a defect in
the system (see troubleshooting) or the load is not dimmable. After a power failure, the dimmer
will again choose between phase control and reverse phase control. If the load appears to be
non-dimmable in automatic mode, you can select either manual reverse phase control or
manual phase control.
To select one of the three operating modes (automatic, manual reverse phase control or manual
phase control), you proceed as follows:
- Press the ‘programming’ key for > 2s. The dimmer is now in programming status, in section
‘physical select’.
- To switch from ‘physical select’ to ‘mode’ in the programming status, it is sufficient to briefly
press the ‘programming’ key.
- Briefly press the ‘select’ key to select the next operating mode.
The selection of one of the different operating modes is indicated by the associated ‘mode’ LEDs
(see following diagram).
