Information for electrically skilled persons

Installation and electrical connection

DANGER

Electrical shock on contact with live parts in the installation environment.
Electrical shocks can be fatal.
Before working on the device, disconnect the power and cover live parts in the area.

Wall mounting

Important: The safest motion detection is obtained when the device is mounted and aligned laterally to the walking direction and no obstacles (such as trees and walls, for example) obstruct the view.
Please note that the motion detector must be protected by a 10 A circuit breaker.
The installation site should be at least 50 cm from a light, since the latter’s heat radiation could result in false triggering of the sensor. The installation height should be approx. 2 m.
Remove mounting plate 1 from device. Do not undo the internal wiring to the terminal block, but extract the block by pulling it gently.
Insert the rubber plugs into the mounting plate. Hold the mounting plate against the wall and mark the drill holes (paying attention to the wiring arrangement in the wall), drill the holes and insert the dowels.
In order to be able to perform a switching operation, a power supply lead with at least two phases must run to the unit and a second lead out to the consumer. The two rubber plugs can be pierced for this purpose with a screwdriver.

After passing the wiring through, the mounting plate can be screwed in place.

Connection of the mains lead The mains lead consists of a 2 or 3 pole cable.

L = Phase conductor (usually black, brown or grey)
N = Neutral conductor (usually blue)
PE = Protective-earth conductor, if present (green/yellow)

If in doubt, the cable must be identified with a voltage tester. Switch off the current again. The wire terminals are for the mains lead. The phase conductor (L) connects into the lower terminal and the neutral conductor (N) connects into the middle terminal. If the green/yellow protective-earth conductor is present, connect this to the bottom terminal provided.

Connection of the service lead The service lead (e.g. light) likewise consists of a 2 or 3 pole cable which is connected to terminals N and L’. The phase conductor of the consumer (black, brown or grey cable) is connected to the terminal marked L’.
The neutral conductor (blue cable) is clamped to the terminal marked N together with the mains lead neutral conductor. Connect any green/yellow protective-earth conductor to the lower terminal.

Important: Getting the cable connections crossed will produce a short circuit in the unit or in your fuse box. In
this case, the individual wires must be re-identified and reconnected. A mains switch for ON and OFF switching can of course be installed in the mains lead.

Wiring examples

1. Fixture without neutral conductor

2. Fixture with neutral conductor

3. Connection via series switch for manual and automatic operation
   

4. Connection to double-throw switch for permanent light and automatic operation

Setting I:

automatic operation

Setting II:

manual operation for permanent light

Important:

The unit cannot be switched off, only optional operation between settings I and II.

1. e.g. one to four incandescent lamps with 100 W
2. consumer, lighting max. 1000 W (refer to Technical specifications)
3. connection terminals of the motion detector
4. indoor switch
5. indoor series switch, manual, automatic
6. indoor double-throw switch, automatic, permanent light

Function

After the motion detector has been connected and fastened to its wall mount, the system can be switched ON.

Two setting options are available after removing the decorative ring **2.

**

Switch-off delay (time setting)

(Factory setting: 10 s)

Light ON duration can infinitely varied from approx. 10 s to a maximum of 15 min

Control dial set to (1) =
shortest time (10 s)
Control dial set to (6) =
longest time (15 min)

The shortest time setting is recommended when adjusting the detection zone and performing the function test.

Twilight setting

(Factory setting: 2000 lx)

The sensor’s response threshold can be

infinitely varied from 2 – 2000 lx
Control dial set to (1) =

daylight operation at approx. 2000 lx Control dial set to (6) = night-time operation at approx. 2 lx The adjusting screw must be turned fully anti- clockwise when adjusting the detection zone and performing the function test in daylight.

Reach setting/adjustment

Assuming an installation height of 2 m, the maximum reach of the sensor is 12 m. Optimum adjustment of the detection zone is possible according to needs. The shrouds provided serve to cover any desired number of lens segments and individually 3

reduce the reach. Fine adjustment is also possible by turning the sensor housing by ± 80°. The shrouds 2 can be divided vertically or  horizontally along the grooved divisions, or cut with scissors. After removing the decorative ring , the shrouds are to be suspended on the upper part of the
sensor lens. The decorative ring  is subsequently **4

** to be reapplied and the shrouds are fixed firmly in place.

False switching by cars and pedestrians, etc. is therefore ruled out, or risk areas deliberately monitored.

Troubleshooting

Malfunction

|

Cause

|

Remedy

---|---|---
Motion detector without power|

• Fuse has blown; not switched ON
• Short-circuit

|

• Replace fuse, switch ON mains switch, check wiring with voltage tester

Product description

Instruction For User

Maintenance/care

The motion sensor is suitable for automatic switching of lights or alarms. The unit is not suitable for special burglary alarm systems, since it lacks the sabotage protection prescribed for this purpose. Weather can affect operation of the sensor. Strong gusts of wind, snow, rain and hail can cause switching errors, since the sudden temperature changes cannot be distinguished from heat sources. The detection lens 5 can be cleaned with a damp cloth (without detergents) if dirty

Disposal

The symbol with the crossed-out wheeled bin indicates that the product must be disposed of separately from household waste at the end of its useful service life in order to enable correct treatment and recycling.

At the end of its service life, the user must therefore take the device free of charge to the municipal collection points responsible for the separate collection of electrical and electronic waste or return it to the dealer.

Separate collection for recycling helps to avoid possible negative impacts on the environment and health, and facilitates the reuse, recycling and/or recovery of the materials in the devices.

Wherever possible, batteries and rechargeable batteries must be removed from the device prior to disposal.

Manufacturer’s warranty

The warranty follows about the specialty store in between the legal framework as provided for by law.
