Optional Voltage Detection System
VDS
The low voltage control panel of a switch panel may be
fitted with a voltage sensor and indicator. These may
vary in functionality but the standard offering, if fitted,
provides the following functionality.
Voltage indicator
A voltage indicator is an indicator with three Light
Emitting Diodes (LEDs) and three socket contacts L1, L2
and L3. It is connected via a signal cable to a voltage
sensor, which is located on the cable section of the panel
to be monitored. Each LED monitors one phase. The
LEDs light up if a voltage is present on the phases
monitored. If they are dead the LEDs do not light up
For details refer to the specific user manual for the
device fitted.
