Device technology
The assignment of the address of the ABB i-bus
out via the ETS and the programming button on the device.
The device features a programming button located on the edge of the device
for assignment of the physical device address. The red programming LED
lights up after the button has been pushed. It switches off as soon as the
ETS has assigned the physical address or the programming button is
pressed again.
On the Light Controller a DC voltage of a few mV can be measured directly
with a multi-function measurement device. Disconnect the sensor from the
LR/S for this purpose. The value is between 0 mV (absolute darkness) and
a few 100 mV depending on the brightness. If 0 mV is also measured at
normal brightness, this is due to an open circuit, short circuit or a defective
sensor.
The Light Controller has a manual operating feature. The switch contact can
be switched ON or OFF and thus the supply voltage to the electronic ballast
using an operating element on the relay. The operating element
simultaneously indicates the switch status.
Note
The Light Controller does not feature electrical monitoring of the manual
actuation and cannot therefore react to manual operation.
From a power engineering point of view the relay is only actuated with a
switching pulse if the known relay position has changed. This means that
after manual operation, a repeated switching command on the bus will not
cause a contact change. The Light Controller assumes that no contact
changeover has occurred and that the correct contact position is set.
An exception to this situation is after bus voltage failure and recovery.
In both cases, the relay position is recalculated in dependence on the
parameterisation and always set depending on the contact setting.
