 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).
