8. Universal dimming module
Operation
The transmission signal of the controller activates one or several outputs on the dimming module. These outputs can also
be activated or deactivated manually using the buttons on the dimming module. Please remember that the activation or
deactivation is only temporary as it will be overruled by the next bus communication.
You can select the type of lighting you wish to dim by adjusting the DIP switches on the front of the module. Use the
potentiometer to select the minimum light intensity for each channel on the front of the module. See
Installation
on page 55
.
Permitted loads
Check the table below to find out the maximum load for each type of lighting at an ambient temperature of 45°C.
* Connect maximum 10 lamps.
The dimmer is fitted with a thermal protection device. If the temperature rises too much due to an overload, the dimmer
will automatically switch itself off. In that case:
• verify that the load does not exceed the maximum permitted load. Remember to take into account the reactive
power of ferromagnetic transformers.
• check the temperature inside the electrical cabinet (45°C maximum).
• check whether mixed loads are being used.
• verify that the setting for the minimum light intensity is not too low.
• check whether the correct type of lighting has been selected.
After a power failure, the dimming module will restore the settings from before the power failure.
Do not use the dimming module to adjust motors used in the installation.
