OPERATION

4.1

Powering on, powering off, selecting the standby mode

Press the POWER key for one second to power on the controller, see Figure 11.

The controller goes through a 6-second start-up sequence coming with Initializing Controller displayed on the
LCD screen. The POWER LED turns off and then is lit in orange.
The controller is ready for use when the main screen is displayed and the POWER LED is lit in green (see
section 4.2.1).
Press the POWER key for one second to power off the controller.

The LCD screen and all LED turn off, except the POWER LED which turns red to indicate that the controller is
not disconnected from mains (see Figure 12). Although it cannot be detected anymore over the network, the
controller still transmits Ethernet data in a daisy-chain topology.
Power loss
If the power has been lost the controller will shut down but all parameters will be restored to same state as
before shutting down when the controller switches on again.
Disconnection from mains
Powering off the controller does not disconnect it from mains.
Standby mode
To reduce the electrical consumption and lock the front panel interface, the controller can be put in standby
mode from LA NETWORK MANAGER (refer to the LA NETWORK MANAGER video tutorial).
While the controller is in standby mode, Standby Mode is displayed on the LCD screen and the POWER LED
is lit in orange.
It is possible to cancel the standby mode from LA NETWORK MANAGER or from the controller front panel
interface ( push and hold the encoder wheel for one second).
