Overview
It is a requirement of many fluorescent lamp manufacturers to have the lamps on at maximum output for a period of time
to guarantee lamp life (refer to the manufacturer’s datasheet for details) As this EBDHS-DD-LT30 is able to dim the
lamps using DALI/DSI, the product provides a facility to disable this for a given period of time.
Operation
By setting the “Burn in” parameter, you can select a time during which the lamps are not allowed to deviate from
maximum output. The unit counts the time, and even remembers how long has elapsed in the event of a power failure.
To cancel the burn in function, simply select a time of 0. Note that when the lamps are changed, the burn in time should
be set again.
Burn-in
The EBDHS-DD-LT30 is designed to be mounted using either:
Flush fixing, or
Surface fixing, using the optional Surface Mounting Box (part no. DBB).
Both methods are illustrated below.
Use the supplied gasket to ensure IP rating
(not compatible with Surface Mounting Box part no. DBB).
