4.17 SDE/SA
The ST750LV does not support the SDE/SA PCB. However, the functionality associated with
Speed Discrimination and Speed Assessment is contained within the standard ST750LV and
ST750ELV controller firmware. Please refer to the doc 667/HH/32900/00 for the appropriate
handset commands.
4.18 Solar Cell
The light sensing LV Solar Cell (P/N 667/1/27872/000) enables the ST750LV to identify the light
level and thus dim the signals when it is dark. The switch is set to operate at 55 lux and release
at 110 lux.
An optional time switch exists, which can be used to regulate dimming control, if required.
The Solar Cell live supply is taken from pin 12, socket 1 of the CPU PCB. Solar Cell input is
applied to pin 12, Socket 1.
