Frequently Asked Questions - BLELC990 JUNG

How does the JUNG BLELC990 transmitter receive power?

The transmitter is battery-free and uses energy harvesting from the mechanical actuation of the rockers to generate the energy needed for transmission.

What is the maximum range of the device?

In free field conditions, the range is up to 75 meters. Inside buildings, the range is approximately 10 meters without wall penetration.

Can I use this transmitter for safety-related applications?

No. The radio communication uses a non-exclusively available transmission path, so it is not suitable for safety-critical functions like emergency stop or emergency call.

How do I restore factory settings?

Carefully remove the rockers, then press all four push-buttons and the activation bar simultaneously for at least 10 seconds. The device resets automatically.

How do I pair the transmitter with a Bluetooth system?

Pairing (teaching-in) is done via the system's app. Two methods are available: scanning the NFC chip integrated in the module, or scanning the QR code on the back sticker.

Is it compatible with all Bluetooth receivers?

It is compatible with various Bluetooth wireless systems. For an up-to-date list, visit the manufacturer's website. The device uses the Bluetooth Low Energy standard.

How do I mount the device?

Mount the holder plate using the adhesive film on smooth surfaces, or screw it onto an appliance box or wall. Then snap the frame and radio module into place, secure with the screw if desired, and snap on the rockers.

What maintenance is required?

Clean the surface with water, degreaser, glass cleaner, or methylated spirit. Avoid bath or all-purpose cleaners. After adhesive mounting, allow 24 hours for full adhesive strength.

Can I replace the rockers?

Yes, the rockers are removable and can be replaced. Use a suitable tool (e.g., button lever) to carefully remove them. Note the 'Top' marking when snapping new ones on.

What does the NFC chip do?

The NFC chip serves as a configuration interface for teaching-in the transmitter to a Bluetooth system. It can be scanned by the system's app to simplify pairing.

Operating instructions

1 Safety instructions

Electrical devices may only be mounted and connected by electrically skilled persons.

Serious injuries, fire or property damage possible. Please read and follow manual fully.

The radio communication takes place via a non-exclusively available transmission path, and is therefore not suitable for safety-related applications, such as emergency stop and emergency call.

These instructions are an integral part of the product and must remain with the end customer.

4 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!

Installation location

The radio range in buildings is approx. 10 m without wall penetration.

A wall penetration is not recommended, because it attenuates the radio signal too much.

Fig. 4: Installation location

In that case, the receiver may not be able to receive the signal from the transmitter correctly Metal parts at the installation site (e.g. metal door frames) or moisture (e.g. in outdoor areas) can also have a negative effect on the radio transmission.

Fitting the device

• Fix holder plate (2) with adhesive film (1) at the installation location. (see section „Adhesive fixing“) Alternatively, screw the holder plate onto an appliance box or directly onto the wall. Note marking „Top“.
• Push frame (3) onto holder plate.
• Snap radio module (4) onto holder plate. arrow on sticker (rear side of radio module) points upwards (or „O“ is up and „I“ is down).
• Optional: Secure the radio module with the enclosed screw (6).
• Snap on rockers (5). Note marking "Top".
  The transport lock (7) behind the rockers must be removed beforehand. (fig. 2)

Adhesive fixing

Important:

The final strength of the adhesive is only reached after 24 hours.

• After gluing the holder plate, let the adhesive cure a little.

Important:

The installation location cannot be changed after the adhesive fixing.

- To test the range, carry out commissioning before adhesive fixing.

Prerequisite:

Surface is dry, clean, stable and even.

Suitable cleaning agents:

water, degreaser, glass cleaner, methylated spirit

Not suitable for cleaning:

Bath or all-purpose cleaner, aggressive detergents

• Remove the protective film from the back of the adhesive film (1).
• Stick the adhesive film aligned on the surface.
  Press firmly for about 10 seconds.
• Remove the protective film (8) for the holder plate (2).
  Do not remove the remaining protective films.
• Stick the holder plate onto the adhesive film.

5 Operation

Fig. 5: Operation

Operating elements

The radio transmitter is operated either via one rocker (2-channel) or via two rockers (4-channel). There are four push-buttons (9) under the rockers. The push-buttons are grouped into two channels (A and B). A distinction is made between two states (I and O) for each channel.

The functions of the rockers (switching, push-button, dimming or blind) are not configured in the factory settings of the device.

Factory settings/Reset

Restoring factory settings:

• Remove rockers (5) carefully with a suitable tool (e.g. button lever).
• Press all four push-buttons (9) and the activation bar (10) simultaneously for at least 10 seconds. (fig. 5) Factory settings are restored automatically. The radio transmitter is no longer taught-in. Rockers are without function.

- Snap rockers on again.

6 Commissioning

The commissioning of the radio transmitter depends on the receiver used in the Bluetooth system. In the following description the commissioning is referred to as "teaching" in the receiver. A channel of the radio transmitter can be taught-in in any number of receivers. After teaching, the receiver can clearly assign the signals of the transmitter.

Teaching-in the radio transmitter

The Bluetooth system used specifies the procedure for teaching. Usually, the system manufacturer provides an app for this purpose. The app explains the teaching procedure step by step. Two methods can be used for teaching:

• NFC chip
  The chip is integrated in the radio module.
• QR code
  The code is on a sticker on the back of the radio module.

Requirements:

• Radio network with receiver is ready for operation.
• Device with app and receiver are within range of the radio transmitter.
• App is installed.

7 Configuration

The functions of the rockers (switching, push-button, dimming or blind) depend on the Bluetooth system used and can be configured in the respective app.

The possible configurations depend on the number of channels or rockers:

• one rocker, 2-channel
• two rockers, 4-channel
