Frequently Asked Questions - BM240S1A JUNG

How to install the JUNG BM240S1A motion detector?

Installation must be carried out by a qualified electrician. Mount the device at a height of about 2 m, at least 50 cm from any lamp. Use the supplied mounting plate, drill the holes, and connect the mains cables (L, N, PE) and the load (L', N) according to the diagram in the manual.

What is the maximum range of the detector?

The maximum range is 12 m when mounted at a height of 2 m. It can be reduced using the supplied snap-on covers.

How to adjust the turn-off delay?

The time delay is adjusted with a knob on the device, from 10 s (position 1) to 15 min (position 6). For testing, set to the shortest duration.

How to adjust the brightness threshold?

The brightness threshold is adjusted from 2 lux (night operation) to 2000 lux (day operation) via a knob. For a daytime test, turn the knob fully to the left.

Why is my detector not turning on?

Check that the fuse is not defective, the switch is in the on position, the lamp works, and the dusk setting is appropriate for the ambient brightness. Also ensure the detection zone is correctly adjusted.

Why does the detector stay on permanently?

This may be due to continuous movement in the detection area, a lamp too close causing temperature variations, a switch set to permanent lighting mode, or a WiFi device too close. Correct these causes.

How to clean the detector?

Clean the lens with a damp cloth. Do not use detergent, as it could damage the sensor.

Can I use this detector for anti-intrusion alarm?

No, the device is not designed for break-in detection or special alarms as it is not vandal-resistant.

Which types of lamps can I connect?

You can connect incandescent/halogen lamps up to 1000 W, fluorescent tubes (with or without compensation), LEDs (depending on power), and capacitive loads. Consult the technical specifications for exact limits.

How to reduce the detection area?

Use the supplied snap-on covers. They are placed on the lens after removing the protective ring. You can break or cut the covers to mask the desired lens segments.

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.

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.

approx. 10 s - max. 15 min

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.

2 - 2000 lx

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 4 provided serve to cover any desired number of lens segments and individually reduce the reach. Fine adjustment is also possible by turning the sensor housing 3 by ± 80°. The shrouds 4 can be divided vertically or horizontally

along the grooved divisions, or cut with scissors. After removing the decorative ring 2, the shrouds are to be suspended on the upper part of the sensor lens. The decorative ring 2 is subsequently to be reapplied and the shrouds 4 are fixed firmly in place. False switching by cars and pedestrians, etc. is therefore ruled out, or risk areas deliberately monitored.

Motion detector does not switch ON	■ Twilight setting in night-time mode during daytime operation■ Bulb burned out■ Power switch OFF■ Fuse blown■ Detection zone not correctly adjusted	■ Adjust setting■ Replace light bulb■ Switch ON■ Replace fuse, check connection if necessary■ Readjust
Motion detector does not switch OFF	■ Continued movement within the detection zone■ Switched ON light is within detection zone and switches ON again as a result of temperature change■ Set to continuous operation by indoor series switch■ Position Wi-Fi device very close to the sensor	■ Check zone and readjust if necessary or apply shroud■ Readjust zone or apply shroud■ Series switch to automatic■ Increase distance between Wi-Fi device and sensor
Motion detector keeps switching ON/OFF	■ Switched ON light is within detection zone■ Animals moving in detection zone	■ Adjust detection zone or apply shrouds, increase distance■ Adjust zone or apply shrouds

Malfunction Cause Remedy

Motion detector switches ON when it should not

■ Wind is moving trees and bushes in the detection zone■ Cars in the street are detected■ Sudden temperature changes due to weather (wind, rain, snow) or exhaust air from fans or open windows■ Position Wi-Fi device very close to the sensor

■ Adjust zone or apply shrouds■ Adjust zone or apply shrouds■ Adjust detection zone or install in a different place■ Increase distance between Wi-Fi device and sensor

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.
