Recommendations
•
Plan programming carefully to avoid having to unnecessarily reset the Minisensor. (See appendix A)
•
Ensure that the Minisensor is located out of view of direct light to ensure correct operation of the
constant light sensor and IR.
•
Position the Minisensor in a area of combined natural + artificial light for best operation of the
constant light feature
•
If multiple sensors are installed, care should be taken to ensure the sensing areas of the Minisensors
do not cross and interfere with each other.
•
Only connect a Helvar Minisensor to the Digidim input of a Helvar EL-si ballast.
•
The Minisensor cannot be directly connected to the DALI interface.
