Frequently Asked Questions - LU361PE2 THEBEN

How to install the LU361PE2 detector?

Installation is done in a false ceiling: drill a hole of 65 mm, pass the cable, connect the connection box according to the diagram, then insert the detector using the fixing springs. Make sure the device is disconnected from power before starting.

What to do if the LED does not light up?

Check that the device is powered and the connections are correct. If the problem persists, the connection box may be defective and must be replaced.

How to adjust the lighting time delay?

Use the Time 1 button: you can choose between Test, Impulse, 1, 5, 15, 30 or 60 minutes. Turn the button clearly to the desired value.

How to perform a walk test?

Set the METER button to 'T' and the Time 1 button to 'test'. Walk through the detection area: the light turns on for 5 seconds and the red LED lights up for 2 seconds. Adjust the detection head if necessary.

Why do lights not turn off?

This may be due to false triggering (presence in the area) or incorrect wiring. Move away from the detection area and check the connections.

How to adjust the light sensitivity (LUX threshold)?

Use the LUX button to choose from 6 levels: 10, 30, 100, 400, 1000 lux or ∞ (disabled). The detector only activates if the ambient brightness is below the set threshold.

What are the causes of false triggering?

Heat sources (radiators, air conditioning), light objects moving with the wind (curtains, plants) or reflective surfaces can cause false triggering. Keep the detector away from these elements.

How to clean the detector?

Use a slightly damp cloth to clean the surface. Avoid abrasive products or solvents. Make sure the device is disconnected from power before cleaning.

Can I connect multiple detectors together?

Yes, you can connect up to two LU361PE2 detectors together, or one LU361PE2 with a LU361PE-S (cable of 3.5 m). They connect in parallel on the connection box.

What is the maximum detection range?

At an installation height of 2.4 m, the detection area has a diameter of approximately 7 m. You can reduce the range with the METER button (from 1 m to 7 m).

FIELD OF VIEW

The LU 361 PE2 LU 361 PE LU 361 PE-S can be mounted on the ceiling and widely used in offices, conference rooms, hotels, utility rooms, kitchens and lavatories. While mounting on locations above mentioned, it is highly recommended to install at height of 2.4M and the detection range with a diameter of approx. 7M (See Fig. 1).

INSTALLATION AND WIRING

A. Select A Proper Location

Since the sensor is in response to temperature change, please avoid the following conditions (See Fig. 2).

• Avoid directing the sensor toward areas or objects whose surfaces are highly reflective or are subject to rapid temperature change, such as pools.
• Avoid mounting the sensor near heat sources, such as heating vents, air conditioners, dryer as vents or lights.
• Do not aim the sensor toward light devices.
• Avoid aiming the sensor toward the objects which sways in the wind, such as curtain, miniature bushes, etc.

B. Installation Procedure

Switch off power supply before installation.

1. Please read the instruction manual carefully before installation
2. Be sure all power supply is switched off.
3. To install the sensor, please drill a hole (diameter of 65~mm ) on the ceiling and keep the power cable above ceiling board (SeeFig. 3).

Fig. 3

Note:

• When installing LU 361 PE2 and LU 361 PE-S on the same ceiling, assure the two holes is max. 3M away and the thickness of ceiling board is 5-25 mm (See Fig. 3 and 8).

• Both LU 361 PE2 and LU 361 PE-S sensor can be connected to one power box at the same time. To install the second sensor (LU 361 PE-S), please keep the signal cable to pass through the hole (SeeFig. 3).

• Unscrew protecting-cover on power box with a screwdriver. One terminal connects power supply and another connects RJ11 plug (See Fig. 4).

1. Wipe gently with a clean and dry cloth if the sensor surface is dirty.
2. Restore power.

ADJUSTMENT AND WALK TEST

A. Adjust sensor head

Note:

Slightly pull out sensor head with a screwdriver at OPEN mark before sensor head adjustment (See Fig. 13).

You can adjust sensor head to meet your detection coverage. It can be adjusted horizontally 350^ (by 30^ step) vertically 30^ (by 5^ step) (See Fig. 14, 15 and 16).

Fig. 16

B. LED Function

1. LU 361 PE and LU 361 PE-S has one RED LED (See Fig. 17). It lights for 2 secs. Once the sensor is triggered and uncontrolled by LUX.
2. LED can be regarded as indicator when performing a walk test without connecting any loads.

Fig. 17

C. Walk Test

The purpose of the walk test is to check and adjust the motion sensor detection range. Turn "METER" knob to "7m", "TIME 1" knob to "test", then you can carry out a walk test and it is uncontrolled by LUX (See Fig. 18).

Note:

• When first time switches the power n or power is re-supplied again after the power is shut off, LED will turn on for 40 secs. then turn off. During the time of warming up, there is no output for LOAD I if it is in test & impulse mode, otherwise it has permanent output as LOAD II. Once any activities are detected after warming up period (40 secs.), LOAD I and LOAD II will operate according to prior settings. If there is no triggering in 20 secs. after warming up period, LOAD I and LOAD II will turn off automatically and won't be controlled by the settings of Time 1 & Time 2.

Fig. 18

Test Procedure

1. Aim the sensor across to your desired detection zone.
2. Switch the power on.
3. Walk from outside across to the detection zone (See Fig. 18). Once the sensor is triggered, the light will turn on for 5 secs.
4. Adjust sensor head to change coverage if necessary.
5. Also can adjust METER knob to change coverage.
6. Repeat step 3 to 5 until you are satisfied with the detection coverage.

KNOB SETTING

Note:

• Slightly pull out sensor head with a screwdriver before knobs adjustment (See Fig. 13).

LUX, METER, TIME knob

Adjust LUX, TIME, METER knobs according to the desired value marked beside each knob (See Fig. 19).

Fig. 19

Time and LUX knobs must be set at value figure marked. DO NOT adjust knobs in between of two value figure marked to cause value functional failure or value confusion.
