Congratulations on the purchase of this NIESSEN electronic device.
You have just acquired a motion detector that is easy to install and offers fle-
xibility of use. This device enables the timed connection and disconnection of
the loads connected to it by detecting people moving in the area covered; this
operation is determined by the preset minimum level of light. The detector offers
the safety, comfort, and well-being that the state-of-the-art NIESSEN techno-
logy gives our society.
THANK YOU for choosing NIESSEN.
1.- Introduction
This motion detector device senses the movement of people in an area of 5 m (maximum) and in a 110°
angle.
Depending on the level of light detected by the light sensor and the motion detected in the covered area,
the device determines if the load connected to it should be activated or not, thus lighting the area in which
it is connected whenever someone passes.
While it is detecting movement, the device maintains the load activated. When it stops detecting motion,
it disconnects the loads in the preset time.
The device enables remote control through conventional pushbuttons with the use of only one conductor,
and thus simplifying electrical installations, with the possibility to substitute the traditional switched
installations.

3.- WIRING
Pre-installation Recommendations
Install the device away from heat sources or draughts.
The sensitivity of this detection device depends on several factors such as temperature, ambient
humidity, as well as speed and direction of people's movement.
Before installing the device, it is important to determine where to install it so that it adequately covers the
desired detection area.
Basic Wiring
The electrical wiring of these devices is performed according to the wiring diagram shown in Figure 3.
The terminal marked "L" shows the phase wire of the installation. The terminal marked "N" shows the
neutral wire of the installation.
The terminals marked represent the two terminals of the relay output (voltage free)
Figure. 3: Basic wiring diagram
The terminal marked "aux" (control terminal) is used in case it is desired to control the device (optional)
from different points through conventional pushbuttons (auxiliary pushbuttons). See wiring diagram in
Figure 4.
It is possible to use the device as a crepuscular switch if a switch is connected to the control terminal
instead to a pushbutton.
Note: Pay special attention to the device input and output conductors, according to the previous
description.
Make sure to disconnect the power supply before manipulating the device.

Wiring of Several Devices in Parallel
The detection area in a zone can be increased by installing more than one motion detector device.
To ensure that the detection of movement by any of the devices installed activates the load controlled by
all of them, their outputs should be wired in parallel to the load. See wiring diagram in Figure 5.
Figure 5: Parallel wiring diagram
Selection of the Light and Time Thresholds
Once the device is wired and installed, based on the type of application, it is important to determine
the light value below which the device should activate the load while in Automatic Mode, either by the
detection of movement or by pressing the auxiliary pushbutton.
The light set point selector (see Figure 6) enables the selection of the light threshold below which the
5 detector will activate the load.
- If the potentiometer is turned to the left (anti-clockwise), the device will activate the load whenever it
detects movement, regardless of the light value, during either day or night.
- If, on the contrary, the potentiometer is turned to the right (clockwise), the device will activate the load
when it detects movement under low light conditions, i.e. almost in the dark.

The load disconnection time is another important parameter that needs to be chosen. The set value will
be based primarily on the type of application and the area in which the detector is installed. The time can
be chosen easily by turning the time selector potentiometer (see Figure 6).
4.- INSTALLATION
To install the device follow these steps
1. Connect the device based on the wiring scheme. Figures 3, 4, and 5.
2. Mount the device on the wall box.
3. Then, position the plate.

5.- OPERATION
The motion detector device has 3 different operating modes that the user can select at any time using the
selector located at the front of the device.
The available operating modes are the following:
I - Always on
A - Automatic (central position)
0 - Always off

Operating Mode "0": Always Off
How to select the operating mode "Always Off"
- The operating selector is in position 0: Always Off
- The front red pilot is off
In this operating mode, the load is always deactivated, regardless of the light level or the movement
detected within the covered area.

While in this mode, the device does not respond to the auxiliary pushbutton that may be connected
to the control terminal.
Operating Mode "I": Always On
How to select the operating mode "Always On"
- The operating selector is in position I: Always On
- The front red pilot is off
In this operating mode, the load is always activated, regardless of the light level or the movement
detected within the covered area.
While in this mode, the device does not respond to the auxiliary pushbutton that may be connected to
the control terminal.
Operating Mode Automatic (A). Motion Detector
How to select the operating mode "Automatic"
- The operating selector is in position A: Automatic
- The device indicates it is in the Automatic operating mode by lighting the front red pilot.
- Optionally, the auxiliary pushbuttons wired to the control terminal can be used.
This operating mode enables the independent activation and deactivation of the load, based on the
movement detected within the covered area and on whether the light level is above or below the set
threshold.
When the device detects movement of people and the light level sensed is below the set point, then it
activates the load. With the conditions described above and while the device detects movement, the load
will be activated.
Once the device stops detecting movement, it will deactivate the load based on the time set for
deactivation; in this way, the device will be on standby until it detects another movement within the
covered area.
When one of the auxiliary pushbuttons that may be connected to the control terminal is pushed, the
device will behave as if it had detected movement. It will activate the load whenever the light level in the
covered area is below the set point and will deactivate the load if no movement is detected within the
time set.
Operating as Crepuscular Switch
The device can be operated as a crepuscular switch, i.e. it can activate the load when the light level is
below the set threshold, no matter if there are people moving in the area or not. In the same way, the
device may deactivate the load when the light level goes above the selected threshold.
How to select the operating mode "Automatic" when the device works as a crepuscular switch
- The operating selector is in position A: Automatic.
- The device indicates it is in the Automatic operating mode by lighting the front red pilot.
- Instead of using auxiliary pushbuttons, wire a switch to the control terminal and then, wire the
terminal to the phase wire. When the switch is closed, the device operates as a crepuscular
MAX
switch
This operating mode is a well defined application derived from the device Automatic operating mode.
MIN In this mode, the device operates as a crepuscular switch, so that when the front light sensor detects a
decrease in the light level below the set threshold, the switch activates the load, regardless whether there
is movement of people or not within the covered area.
TIME
Once the light in the room collected by the sensor exceeds the set light threshold, it disconnects the load.
Note 1: For the correct operation of the device as a crepuscular switch, the device should be kept away
MAX MIN MAX
from the light source (load) it controls. In this way, the purpose is that the device's light sensor only
collects the room light (not artificial) that will determine if the light loads automatically controlled by the
10 seg 10 min
device should be turned on or off.
Furthermore, the device needs to be kept away from the light load it controls for its correct operation.
Note 2: This operating mode automatically decides whether to connect or disconnect the loads, based
solely on the light collected by the device's light sensor. Therefore, the operation of the device does not
rely on or respond to the movement of people within the covered area, if the switch connected to the
control terminal is closed to the phase wire.
