Frequently Asked Questions - 2997 HAGER

How do I switch the light on/off using the DALI potentiometer?

Press the control knob briefly to toggle the light on or off.

How can I adjust the brightness?

Turn the control knob. Turn slowly for small changes, quickly for larger changes.

How do I set the color temperature?

Press and hold the control knob, then turn it: left (W) for warmer light, right (C) for colder light.

Can I save a specific switch-on brightness?

Yes. Switch on the light, set desired brightness, then double-click the knob. The light flashes twice to confirm. To delete, switch off then double-click.

What happens after a mains voltage failure?

When power returns, the lighting restores to the brightness and color temperature present before the failure.

How many DALI devices can one potentiometer control?

Up to 26 DALI subscribers. Parallel connection of up to 4 units supports up to 104 subscribers.

How do I set a basic brightness?

Set lighting to minimum brightness, turn the knob until brightness starts to increase, then press the knob for >10 seconds. Lighting flashes off/on to confirm.

How do I save color temperature limiting values?

Press and turn the knob to the desired warm limit (left) or cold limit (right) and hold for >10 seconds until light flashes three times.

Can I delete all saved settings?

Yes. Switch off lighting, then press the knob for >10 seconds. The light flashes to maximum brightness then off, deleting basic brightness and color temperature limits.

What should I consider when wiring multiple potentiometers in parallel?

Ensure correct polarity. If multiple circuit breakers supply dangerous voltages, couple or label them to guarantee disconnection.

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.

Danger of electric shock. Always disconnect before carrying out work on the devise or load. In so doing, take all the circuit breakers into account, which support dangerous voltages to the device and or load.

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

3 Function

Intended use

– Brightness setting for luminaires with DALI interface
- Setting the colour temperature for luminaires with DALI Device Type 8 for Tunable White in accordance with IEC 62386-209
- Mounting in appliance box according to DIN 49073

Product characteristics

- The DALI potentiometer with power supply unit supplies the control current for 26 DALI subscribers.

• Parallel switching of up to four DALI potentiometers with power supply unit with the option of supplying up to 104 DALI subscribers.
• The DALI potentiometer without a power supply unit is powered using the DALI voltage and serves as an additional control section.
• Saving of colour temperature limiting values and a basic or switch-on brightness.

To ensure fault-free operation, do not combine the device with other DALI controllers.

Behaviour after a mains voltage failure

When the mains voltage returns, the lighting is switched to the brightness and colour temperature present before the mains voltage failed.

4 Operation

Operation can take place from multiple control sections and always applies to all connected subscribers (broadcast).

Switch light

■ Press the control knob.

Adjust the brightness

■ Turn the control knob.

Turn slowly = Brightness change small Turn quickly = Brightness change great

Figure 2

■ Turn pressed control knob.

Turn left (W) = warmer light (reduce colour temperature) Turn right (C) = colder light (increase colour temperature)

Save switch-on brightness

If the lighting is not always to be switched on with the same brightness, then this can be saved as a switch-on brightness.

■ Switch on light.
■ Set required switch-on brightness.
■ Press the control knob briefly twice in succession (double-click).

The lighting briefly switches to maximum brightness twice. The switch-on brightness is saved.

If the lighting switches off after the double-click, then the time between the first and second presses was too long.

Delete switch-on brightness

■ Switch the light off.
■ Press the control knob briefly twice in succession (double-click).

After about 2 seconds the lighting switches to maximum brightness.

The switch-on brightness has been deleted.

5 Information for electrically skilled persons

DANGER!

Mortal danger of electric shock.

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

5.1 Fitting and electrical connection

Connecting and fitting the device

■ Connect the DALI potentiometer and DALI electrical ballast according to the wiring example (Figure 3). In so doing, observe the data of the electrical ballast manufacturer.
■ When switching multiple DALI potentiometers with a power supply unit in parallel, ensure correct polarity.
■ If multiple circuit breakers supply dangerous voltages to the device or load, couple the miniature circuit breakers or label them with a warning, to ensure disconnection is guaranteed.

i Ensure that the control cable is of the appropriate type, cross-section and routing for the VDE specifications for 250 V cable, control voltage has basic insulation.

The control cable and load cable can be run in a shared cable, e.g. NYM J 5×1.5.

The connected DALI subscribers may be operated on different phases.

5.2 Commissioning

Saving a basic brightness

The basic brightness should be set to a state that does not directly lead to an increase in brightness when turning the DALI potentiometer at minimum brightness.

■ Set lighting to minimum brightness.
■ Turn the DALI potentiometer to the point that where the brightness begins to increase.
■ Press the control knob for longer than 10 seconds.

The lighting switches briefly off and on again. The basic brightness is saved.

Saving colour temperature limiting values

The setting range of the DALI potentiometer can be adjusted to the colour temperature of the luminaire with this setting.

When saving the colour temperature, you must ensure that the last turn of the pressed control knob (Figure 2) is made to the left for the warmest light colour (W) and to the right for the coldest light colour (C).
■ Turn pressed control knob to the left (W) until reaching the warmest light colour required, and hold it in this position for more than 10 seconds. The light switches off three times and then switches on again. The warmest light colour is saved.
■ Turn pressed control knob to the right (C) until reaching the coldest light colour required, and hold it in this position for more than 10 seconds. The light switches off three times and then switches on again. The coldest light colour is saved.

Deleting the basic brightness and colour temperature limiting values

■ Switch the lighting off.
■ Press the control knob for longer than 10 seconds.

Briefly switch the lighting to maximum brightness and then off again. The stored values are deleted.
