Frequently Asked Questions - ME5232S JUNG

How do I move the blind up or down?

Press and hold the top or bottom of the cover for more than one second. The blind will move to the end position or stop if you press again. For slat adjustment, press briefly (<1 second).

How to activate and deactivate lock-out protection?

To activate, press the top of the cover for more than 4 seconds until the status LED lights up. The blind moves to the upper end position. To deactivate, press the top button briefly; the LED goes out. Lock-out protection is disabled after a power failure.

How do I store an individual moving time?

Press the cover over its entire surface for >4 seconds. The LED flashes and the blind moves to the upper end. Keep pressing in the ▼ direction until the blind reaches the desired position, then release. Press the entire cover for >1 second to store the time, or press ▼/▲ to cancel.

What does the sun protection function do?

When the brightness exceeds the threshold for more than 2 minutes, the blind moves down automatically (sun protection). It returns to the upper end position when brightness stays below threshold for >15 minutes. This function only works if the blind was at the upper end and the control turned off after 2 minutes.

How to adjust the brightness threshold for the sun sensor?

On the back of the cover, use the adjuster (marked with small sun/large sun) to set the threshold between approx. 5,000 lx and 80,000 lx. Factory preset is ~15,000 lx. Adjust after commissioning if needed.

What types of sensors can be connected?

For the ME5232S (with sensor connection), a sun sensor is used. Compatible accessories include the sunlight/dawn sensor (Art. 32 SD) and extension flex (Art. 32 K).

Can I use this device with outdoor sensors?

Yes. The device automatically recognizes an outdoor sensor during the first sensor run. The stored individual moving time is then applied when the sun protection function triggers.

What should I do if the blind stops responding?

Check if lock-out protection is activated (LED on). If so, deactivate it by a short press. Also ensure the sensor connection is correct polarity. If problems persist, disconnect power and consult a skilled electrician.

Is the device suitable for disconnecting the supply voltage?

No. The device is not suitable for disconnection from supply voltage. Always use the circuit breakers to disconnect power before working on the device or load.

What are the environmental operating conditions?

Ambient temperature: 0 °C to +45 °C. Storage/transport: -10 °C to +60 °C. Suitable for indoor use only (IP20).

3 Function

Intended use

• Operation of electrically-driven blinds, shutters and awnings
• Operation on control of the Venetian blind control system

Product characteristics

• Status LED
• Lock-out protection
• The individual moving time from the upper end position is storable

Additional functions for the cover with sensor connection

• Evaluation of a sun sensor
• Brightness threshold adjustable
• Automatic recognition of an outdoor sensor during the first sensor run

Sun protection function for cover with sensor evaluation

The connection of a sun sensor enables automatic shading when it is very bright outside. The brightness threshold that controls the sun protection can be adjusted on the cover. If the measured brightness exceeds the predefined brightness threshold for more than 2 minutes, the Venetian blind moves downwards. The previously stored individual moving time is executed for an outdoor sensor. The stop position is determined by the sun sensor for an indoor sensor.

The sun protection function is only activated if the Venetian blind has been moved to the upper end position and the control has deactivated automatically after 2 minutes. Each manual operation deactivates the sun protection.

If the brightness threshold is fallen short of for more than 15 minutes, the Venetian blind moves back to the upper end position.

4 Operation

Moving the Venetian blind

■ Press top or bottom of cover for longer than one second.

The Venetian blind moves in the desired direction to the end position or stops when the button is pressed again.

Adjusting the slats

■ Press top or bottom of cover for shorter than one second.

The slat position changes in the desired direction for as long as the button is pressed.

Activating lock-out protection

The lock-out protection prevents the Venetian blind from automatically moving down unintentionally. Shutting down on site via the sensors or extensions is disabled.

■ Press top of cover for longer than 4 seconds.

Status LED is illuminated. Venetian blind moves to the upper end position, the lock-out protection is activated.

Deactivating lock-out protection

■ Press top button briefly.

Status LED goes out.

The lock-out protection is deactivated.

i After a power failure, the lock-out protection is deactivated.

Saving individual moving time

If a Venetian blind should not move to the lower end position "ventilation function" or an outdoor sensor is used, a shorter moving time can be stored. A time between 0.5 seconds and 2 minutes can be stored.

■ Press cover over entire surface for longer than 4 seconds.

The Status LED flashes. The Venetian blind moves automatically to the upper end position.

- Keep the cover pressed in the direction ▼ until the Venetian blind is in the desired position.

■ Release cover.

Venetian blind stops.

■ Press cover over entire surface for at least 1 second to store the moving time.

- Or -

■ Press cover ▼ or ▲ to discard the moving time.

The storage mode is exited automatically and the LED ceases to be illuminated.

The individual moving time remains permanently stored. The old moving time will be replaced if a new moving time is stored.
To execute the individual moving time, the Venetian blind must be moved to the upper end position and switch off there automatically after 2 minutes.

5 Information for electrically skilled persons

5.1 Fitting and electrical connection

Mounting and connecting

DANGER!

Electrical shock when live parts are touched.

Electrical shocks can be fatal.

Before carrying out work on the device or load, disengage all the corresponding circuit breakers. Cover up live parts in the working environment.

The Venetian blind control is mounted and connected properly (see instructions for the relevant Venetian blind control).

■ Install sun sensor for covers with sensor connection and connect to terminal block (see instructions for the sensors and control).
■ Adjust brightness threshold (see following chapter).

Connect the sun sensor with the correct polarity. If a sensor is connected with reversed polarity, this will result in malfunctions. It might not be possible to operate the cover any more.

■ Mount cover (3) with frame (2) onto the Venetian blind control (1) (figure 1).

Adjusting brightness threshold for cover with sensor evaluation

Figure 2: Back of cover: Adjuster for brightness threshold

The brightness threshold can be adjusted within a range of approx. 5,000 Lux "small sun" to approx 80,000 Lux "large sun" using the adjuster (5) on the back of the cover (figure 2). The adjuster is preset to approx. 15,000 Lux at the factory.

■ Adjust the brightness threshold to the required value. Adjust the brightness threshold value after commissioning if necessary.
