The dimmer has two additional ‘bus info’ LEDs (see fig. 1) that give information about the status
of the DALI bus.
The ‘activity’ LED blinks when there is activity on the DALI bus.
The ‘bus error’ LED blinks if the dimmer no longer is connected correctly to the DALI bus or if
there is a fault on the DALI bus.
6. WARNINGS WITH RESPECT TO OPERATION
- This appliance is not suitable for the control of motors.
- When using a ferromagnetic transformer, check whether it is suitable for use in combination
with an electronic control.
- When using halogen lighting with wire-wound transformers, the efficiency of the transformers
must be taken into account. Load the transformers to at least 80% of their nominal power.
Take into account the efficiency of the transformer when calculating the total dimmer load. The
transformer must be suitable for dimming.
- Electronic transformers may behave unstably if the wire length between the transformer and
the lamps exceeds 2m.
- This dimmer produces a limited amount of heat under normal operating conditions. Allow for
sufficient heat dissipation; do not cover the dimmer with insulating material. Take into account
the maximum power when installing several dimmers on top of, or alongside each other. Install
a fan, if necessary.
- When installing several dimmers on top of, or alongside each other, it may be necessary to
reduce the maximum power (see load table).
- When installing the dimmer near an audio system, it is advisable to use shielded wires to
interconnect the various system components.
- Lamps connected via dimmers do not produce the maximum light intensity. Their light output
will always be less than an identical lamp connected directly to the mains.
- The dimmer is provided with a “PLC” filter. This filter ensures that any interference caused by
signals transmitted over the mains is suppressed as much as possible.
- Do not switch on the dimmer if the transformers are not loaded.
