Use of the push-buttons for local command
The front test push-buttons (figure A
channels or brightness control from 0% to 100% and vice versa each time they are pressed
(default setting).
The local commands are executed also if a priority command is active.
It is possible to configure the behaviour of the front push-buttons via ETS.
Any possible overheating is signalled by a fixed red fault signalling light on the front LED. While
overheating, the dimmer outputs are fixed and equal to 10% and every command received from the
BUS is ignored. Once the cause for overheating has been removed and the normal operating
temperature is reached, the output channel LEDS will flash green. Normal operation can be restored
and the overheating signal can be deactivated as follows:
- using the front output test button keys. The controlled channel goes to the maximum brightness
value and, after approx. 5 seconds if the temperature remains under the alarm value, the fault
signalling LED turns off and the status LED returns to the condition it was in before overheating.
During the reset operation (about 5 seconds) the fault signalling LED remains fixed red, whereas the
status LEDs all start to flash red;
- sending a command via BUS. If the temperature has gone below the alarm value, the dimmer
will perform a test, independently of the received command, bringing all the outputs to the
maximum brightness values. After approx. 5 seconds, if the temperature remains under the
alarm value, the fault signalling LED will turn off and the dimmer will execute the last
command received. During the reset operation (about 5 seconds) the fault signalling LED
remains fixed red, whereas the status LEDs all flash red.
Use a dry cloth if cleaning is required.
