Functions

The interface converts the desired DALI dim level into a corresponding PWM pattern or analog output voltage. From firmware version 2.0, device type 5 is supported, allowing for both linear and logarithmic control characteristics. For the PWM types, the output range can be selected between 0-10V and 1-10V. The DALI value [0-254] is converted linearly or logarithmically to the output range.

The SPST relay is directly linked to the 8-bit direct arc power level. If the value is 0, the relay is OFF; at any other value [1…254], the relay is ON. The combination of the 0-10V control signal and the additional SPST relay offers the possibility to power on/off the mains supply of the 0-10V controlled electronic ballast.

In case of a system failure, 100% (10V) is applied to the 0-10V control output. The relay's behavior depends on the firmware version. In any case, the relay holds the output state. In newer versions, the system failure level can be set. The relay can be switched on or off or set to hold the current state (option available from FW 3.5.0 at 86458667-DE, from FW 3.3.0 at 86458668, and from FW 1.3.0 at 86458668-AN).
