7. Connection
Depending on the application, the presence detectors are
designated as Master or Slave. The devices are identical, but
have a different wiring.
The presence detectors can be combined as Master in
individual switching, Master in parallel switching or Master/
Slave parallel switching. Several buttons can be connected to
one control input. Illuminated buttons can only be used with
neutral conductor connection.
Individual switching
In individual switching, the presence detector, as Master,
detects presence and brightness and controls lighting.

Master/Slave parallel switching
If the detection area covered by one presence detector is
insufficient (larger rooms), then up to 10 detectors can be
operated in parallel by connecting the P terminals. In the
process, presence detection is performed by all detectors
together. The Master measures the brightness, operates the
buttons and controls the lighting. All other detectors are used
as Slaves. They only provide presence information.

Master/Master parallel switching (for several
lighting groups)
Several Masters can be used in parallel switching. Each
Master controls its lighting group according to its own bright-
ness measurements. Delay times and brightness setpoint
values are set individually on each Master. Presence continues
to be detected by all detectors.

8. Settings
The presence detectors were supplied with basic settings
ready for operation. The specifications are guidance values.
The "SendoPro 868-A" management remote control or the
installation remote control "theSenda P" are optionally
available for installation support. They enable remote set-
ting. The "SendoPro 868-A" can be used to query, adjust and
optimise parameters. Parameters can only be adjusted with
the "theSenda P". In this sense, the remote controls serve as
set-up aids. A range of alterable parameters is available for
adjustment with the remote control (see chapter "Parameters
via remote control").
Settings Channel A light
Potentiometer - Brightness set point value „lux“
•
Operating mode - Constant lighting control (reg.on)
The required brightness setpoint value can be set via the
potentiometer. The setting range is around 15 to 3000 lux.
The factory presetting is 300 lux.
