Operating Instructions
WG 800 Automatic Switch 180

1. Safety Instructions

Attention: The installation and assembly of electrical equipment
may only be performed by a qualified electrician. Not suitable for
safety disconnection.

To avoid electric shock, safely disconnect the automatic switch
(switch off the automatic circuit breaker) prior to working on it, or
before changing the lamp.)

Non-observance of these installation instructions may cause fire or
other hazards.

2. Function

Function Principle

The automatic switches respond to thermal movements initiated by
persons, animals or objects and trigger a switching process. The
automatic switches remain switched on as long as some movement s are
detected, otherwise they will switch off after their shut-off delay time has
elapsed. Optionally, the automatic Switch can also be set to short-time
operation. This facilitates the activation of acoustic signal transmitters
(bell) to observe an entrance door. The automatic switches have been
designed for operation together with a switching insert.

Important: These automatic switches are not suitable for alarm systems.
Depending on the lens used, the nominal installation height is

1.10 or 2.20 m.
The 2.20 m lens automatic switches can also be installed at

the height of 1.10 m.

instructions of the respective insert.

Detection Field of the 1.10 m Lens Version

The 1.10 m automatic switches have a two-level detection
field with an opening angle of 180° (Fig. 3).

Figure 3

Detection field area (Fig. 3): approx. 10 m x 12 m
The information on the detection field area is referred to an

installation height of 1.10 m. For different installation heights, the nominal
working range varies.

Due to the alignment of the upper lens level, the detection field is spatially
not limited. This may, among other things, cause movements out of the
specified detection field to trigger switching events (over-ranging).

Important: Due to the almost horizontal alignment of the upper detection

level (Fig. 4), the automatic switches using the 1.10 m lens are
suitable for indoor use only. Otherwise, direct sun radiation may
destroy the automatic switch.

Detection Field of the 2.20 m Lens Version

The 2.20 m automatic switches have a three-level detection
field with an opening angle of 180° (Fig. 5).

Detection field area: approx. 12 m x 12 m
The information on the detection field area is referred to an

installation height of 2.20 m.

Note:

The detection levels of the automatic switches using 2.20 m
lenses are inclined from top to bottom (Fig. 6). This permits
the outdoor use of the water-protected design (IP 44).

If the installation height deviates from 2.20 m, the working range will vary.
A bigger installation height leads to a correspondingly wider reach. It
must, however, be noted that the energy radiated by a remote heat signal
source may, under certain circumstances, not be sufficient to trip the
automatic switch.

3. Installation

Information on the Place of Installation
The automatic switches will detect a movement to an optimum when they

are installed laterally to the moving direction (Fig. 7). Otherwise, delayed
detection will have to be expected.

Figure 7

Note: Select the place of installation so that no direct sun radiation

falls into the sensor lens. Do not expose the automatic switches
to direct sunlight during their installation. Otherwise, the intense
thermal radiation may destroy the sensor (Fig. 8).

Figure 8

To avoid unintentional switching events, please follow these instructions
(Fig. 9) as early as during the installation:

• Exclude interference sources such as lamps or heating radiators
from the detection field: Choose a suitable place of installation or
use the slip-fit mask (refer to ‘How to Use the Slip-Fit Mask’).

• Reflection of thermal radiation from the light or too short a distance
between the automatic switch and the lamp may re-trigger the
automatic switch.

Important: The automatic switch automatically adapt to the ambient

conditions. This will render almost impossible any unintentional
switching events. Nevertheless, if any unintentional switching
events should occur, adapt the sensitivity manually (refer to
Para. 4.6), or use the slip-fit mask (refer to Para. 3.2).

4. Mask Function

You can use the attached mask to eliminate interference sources by
limiting the detection field. The mask can cover the left or right half of the
detection field (90° each) (Fig. 10).

Figure 10

Cutting out the mask for smaller angles will result in malfunctioning.
