Stand-Alone DALI Group Dimmer for 4 groups

• Function description

  A maximum of 64 DALI(2) lighting devices can be connected to the QDG04SA and distributed across 1 to 4 available groups. The devices can only be operated via one of the four available DALI groups. This module does not support sensors and color controls. The QDG04SA is equipped with a built-in DALI(2) BUS power supply. The module has four buttons on the front for operating the groups and configuring in Stand-Alone mode. 

  The module is also equipped with an ECO relay, so that in systems where it is possible, the power supply can be interrupted. This function is automatically activated when setting a Power ON and Failure level in the DALI drivers via the Stand-Alone learning menu (choice 3 on Button 4) or via System Manager III.

  Stand-Alone operation:

  Configuration can be set up in Stand-Alone mode without the intervention of software, an app, or external equipment. 

  The module has 5 potential-free inputs for connecting standard (N.O.) push buttons. Inputs 1 to 4 operate the respective groups. The A input functions with a pulse between 0.7 sec and 3 sec as an All Off (0%) command. A long pulse > 3 sec on the A input functions as an All On (100%) command. By linking the A inputs of different Stand-Alone modules, multiple outputs on different modules can be group-controlled. 

  Once the module is provided with 230V AC power supply, all DALI(2) devices are connected to this QDG04SA, and the DALI(2) lighting devices are also powered, the installation can be tested and operated via the connected push buttons. As long as no configuration has been done, all devices can be controlled together in Stand-Alone mode via the directly connected push buttons. Thus, without configuration, this module works as a single dimming control for all connected DALI(2) devices. Then configuration can be started via the buttons on the front of the module. Both adjustments of dimmer options and DALI settings are done via the two available learning menus. See details below in the description of the Stand-Alone learning mode.

  Additional Stand-Alone functions can also be set when the QDG04SA is connected to a controller. Once the additional settings are configured, the controller can be disconnected from the module. 

  The following functions can be set in this way via the Qbus configuration software:

  • the operation of input A for each output
  • input delays for All Off/On
  • cascade time via input A for the entire module between 0 and 254 seconds

  The cascade control avoids a peak load when, for example, many consumers are controlled simultaneously via input A. Once these changes are programmed, the module can be disconnected and operate Stand-Alone with these settings. There are also 4 connections for LED feedback (5-24V DC) to display the status of the DALI lighting groups.

  Combination with CTD

  If the module is connected to a Qbus controller (CTD), the DALI addressing and the assignment of devices to one of the 4 groups can be done via System Manager III. In addition, extra parameters of the LED drivers can be changed via System Manager III. No additional/external DALI programming hardware and/or software is needed. For example, you can set the physical minimum and maximum level per driver, as well as the behavior for the DALI function “Power ON” and “System Failure”. The standard behavior of DALI devices is that as soon as power is available, the device goes 100% On. Also, when no DALI-bus is detected, a DALI device will go 100% On. By changing this setting, DALI devices can retain their status in the event of a power or DALI-bus failure, and the function of the ECO relay is activated. 

  The QDG04SA, like every Qbus module, has a unique serial number that is entered when configuring, in the configuration software System Manager III. All programmed data remains stored internally in permanent memory.

General

• Safety Instructions

  Read the full manual before installing and activating the module.

  WARNING

  • The module must be installed, started, and maintained by a certified electrical installer in accordance with the applicable legal regulations of the country.
  • This module is suitable only for DIN-rail installation EN50022. The module must be installed in a fire-resistant, closed distribution cabinet with ventilation grilles.
  • Before working on the QDG04SA, the power supply must be switched off.
  • Never connect external voltages (e.g., 230Vac) to the DALI buses, the Qbus bus, or the SA inputs! This will cause irreparable damage to the module and/or connected devices.
  • The module must not be opened. The warranty is void if the module is opened!
  • A single DALI device may draw 2mA bus current so that the maximum of 64 devices can be reached.
  • NOTE! Not all systems will be suitable to use the function of the ECO relay. If optimal operation cannot be achieved, do not use the function of the ECO relay.

Installation and cabling

• Installation

  Click the module onto a DIN rail DIN EN50022.

• Power Supply

  WARNING: DISCONNECT THE POWER SUPPLY TO THE MODULE BEFORE WORKING ON THE MODULE!
  A two-pole automatic circuit breaker with a maximum of 16A must be connected to the module's power supply of 230Vac. However, protection from 2A is sufficient. 
  Conductor cross-section: minimum 1.5mm² at 16A. Strip approximately 7mm of insulation from the conductor and screw the conductor into the connector L-N.

• Load

  The QDG04SA provides a single DALI(2) bus for up to 64 DALI(2) devices, calculated at 2mA per DALI(2) device. The power supply for the lighting devices is provided outside the QDG04SA. No external voltage or 230V should be connected to the DALI(2) bus!

  Two pairs of conductors can be connected to the DALI push-in terminals. There is an internal bridge between the terminals, so there is no difference between the first DALI+ & DALI- terminal and the second DALI+ & DALI- terminal. Strip about 7mm of insulation from the DALI wires and insert the bare conductors into the DALI push-in terminals + & -. Both solid and stranded wires ranging from 0.5 – 1.5mm² can be used. For stranded wire, a screwdriver must be used to press on the spring of the push-in terminal when inserting the wire.

  The wires can be released by pushing down on the spring of the push-in terminal with a screwdriver while simultaneously pulling the wire out with little force. However, do not make a twisting motion with the screwdriver, as this can lead to irreparable damage to the push-in terminals! Power to the lighting devices should only be switched on after all connections have been checked and the DALI bus is powered. In rare cases, devices that are powered before the DALI bus is activated cannot be addressed. In such cases, switch the power of these devices off and then on again.

• SA inputs

  Remove approximately 7mm of insulation from the cable and insert the cable into terminals 1 through A. Both solid and stranded wire between 0.5mm² – 1.5mm² can be used. For stranded wire, use a screwdriver to press on the spring clamp when inserting the wire. 

  The wires can be released by pressing on the top of the spring clamp with a screwdriver while gently pulling out the wire without applying excessive force.

  Push buttons connected to inputs 1 to 4 control groups 1 to 4 respectively. 

  Input A is set by default as a scene input: pressing and releasing the button connected to this input after 0.7 seconds sets all groups to the OFF status; pressing the same button for more than 3 seconds sets all groups to the ON status. 

• Stand-Alone LED feedback

  There are 4 connections for LED feedback (5-24Vdc) to display the status of the DALI lighting groups.

• BUS connection

  It is recommended to use the Qbus cable or any other cable with a minimum of 2 conductors of 1mm² as the bus cable. The green shielded EIB cable can also be used if the conductors are paired to achieve a minimum cross-section of 2 x 1mm².

  Stand-Alone learning mode:

  As long as no configuration has been done, you can control all devices together in Stand-Alone mode via the directly connected push buttons. You can also use one of the four buttons on the front of the module to test the installation before any configuration has been done. So without configuration, this module functions as a single dimming controller for all connected DALI(2) devices. Once the installation is functioning, configuration can start. Both assigning devices to groups and changing dimmer options and DALI settings are done via the two available learning modes that you can activate using the buttons on the front of the module. To configure a new installation, start with learning mode, which you activate with buttons 3&4. Then you can change dimmer properties per group using the learning mode of buttons 1&2.

  To activate a learning mode, follow these steps (both learning modes apply the same method):

  1) Turn all outputs OFF (= all orange LEDs are off). 

  2) Press buttons 1(3) and 2(4) simultaneously. The red STATUS LED on the module will blink rapidly for 5 seconds and then start blinking at a slower rate. 

  4) Once the STATUS LED starts blinking slowly, release one of the buttons, and 2 seconds later, release the other button. The red STATUS LED will continue blinking: the module is in learning mode. If nothing happens, the red STATUS LED stops blinking, and the module is no longer in learning mode. 
  After more than 30 seconds of inactivity, the module will exit its learning mode.

  Learning mode via button 3 & 4: In this mode, an addressing check is automatically started: this checks for corrupt addresses. At that moment, you see a running light over the orange LEDs next to the 4 buttons on the module. If a corrupt address is found, LED 4 will start blinking rapidly. If you then press button 4, the corrupt address will be erased. After the addressing check, you can use the following functions via the buttons:

  Button 1: 

  • Short press (LED lights up briefly) = Start actual addressing. If devices are already configured, only new devices are addressed/added, for example, when a driver was faulty and replaced in an existing installation. During addressing, the orange LED next to button 1 blinks slowly. Once addressing stops and one or more new devices have been addressed, this LED blinks faster for a short time and then goes out.
  • Long press >5sec = erase all = return to factory settings => the module has an empty configuration and the addresses and groups in drivers are erased.

  Note: All devices are also added to groups 14 and 15 during addressing, which is controlled by the All On/All OFF input. No additional actions are needed for this.

  Button 2: 

  • Short press (LED lights up briefly) = Start assigning devices to the switch/buttons. Assignment on the switch is done by briefly pressing the desired button. LED 2 on the module blinks rapidly. Once all available devices have been assigned, this function automatically stops. During assignment, you can press Button 2 to interrupt/stop the assignment to switches.

  Button 3:  

  Short press (LED lights up briefly) = Function “Move device to another switch/group” => Then go to the switches for further assignment. Assignment on the switch: short press = select next device (device blinks) Long press on the desired switch = assign the blinking lamp to the new group. The group of the selected lamp dims to 40-50% while the lamp is blinking. Long press on the desired switch changes the lamp to the new group. The new group dims softly so you can see which group it is in. [LED 3 on the module blinks rapidly (indicates the mode the module is in + guides the installer out of this mode)] You can press Button 3 at any time to stop. After all devices are cycled through, it returns to device 1. It does not stop automatically! So once you're done, you need to press Button 3 again to stop the function.

  Button 4: 
  Press button 4 several times to activate specific DALI driver settings. If two options are desired within the same menu, you need to exit the module from learning mode after the first choice and then

  instelling	aantal maal drukken
  Instellen maximaal bereik drivers: Stel minimum dimniveau van de DALI toestellen op 10% en het maximum op 100% Toepassen op ALLE toestellen onder spanning	1x
  Behoud status na bij wegvallen van spanning of DALI-signaal + ECO-relais wordt actief	2x
  Set Power ON-level to 254 (100% branden wanneer spanning opkomt) broadcast all & Set DALI failure level to 254 ( 100% bij wegvallen van DALI-bus) DIT IS DE STANDAARD INSTELLING VAN NIEUWE DALI-DRIVERS!	3x

  If the learning mode is active via buttons 3 & 4, and it takes longer than 30 seconds to find a new DALI fixture or if there are no other operations on the front buttons (for example, other selections in the SA menu), the learning mode stops automatically.

  Example of commissioning:

  1. Set all outputs OFF (all orange LEDs are off).
  2. Press buttons 3 and 4 simultaneously. The red STATUS LED on the module will flash rapidly for 5 seconds and then start flashing at a slower rate.
  3. Once the STATUS LED starts flashing slowly, release one of the buttons, and 2 seconds later, release the other button.
  4. The red STATUS LED continues to flash: the module is in learning mode.
  5. The module indicates it is reading the DALI installation with a running light over the orange LEDs next to the buttons. Once this stops, you can start DALI addressing by briefly pressing button 1. If the module actually finds DALI devices, the LED next to button 1 will continue to flash slowly during addressing. Once the addressing is done, and the module has found new devices, the orange LED next to button 1 will flash quickly and then stop. The red STATUS LED will continue flashing for another 30 seconds. You can make the next choice during this time.
  6. You can now start assigning groups by briefly pressing button 2. The orange LED next to button 2 now flashes slowly. A DALI device will be blinking.
  7. Go to where the lighting and connected buttons are mounted. You can assign the device that is now blinking on and off by briefly pressing the desired button. The device is assigned, and the next device will start blinking. Repeat this method until all devices are OFF.

  If no further action is taken, the red STATUS LED will stop flashing after 30 seconds, and the module is out of learning mode.

   

  Learning mode via button 1 & 2: 

   

  Activation of the learning mode via button 1 & 2 is similar to the learning mode via button 3 and 4 as previously indicated. In this mode, you can adjust settings per group by pressing the respective button several times.

   

  The dimming groups are by default set with a minimum dim level of 10% and without memory function. If you want to dim to 0% or use a memory function (whereby, when turning on that light circuit, the dim level returns to the last dim level before the circuit was turned off), this can be set via the learning mode with buttons 1&2. 

  Once the module is in the respective learning mode, you can adjust the dimming properties of the group by pressing the button a number of times. The orange LED next to the button lights up each time it is pressed. See the choice table below. The setting indicates how many times the button must be pressed: 

  Instelling	Aantal maal drukken
  Dim minimum 0 % (deep dimming)	1x
  Dim minimum 10% (standaard Qbus)	2x
  Dim minimum 20%	3x
  Dim minimum 34% (standaard bij DALI)	4x
  Geheugenfunctie Uit (standaard)	5x
  Geheugenfunctie Aan	6x

  Example of adjusting the minimum dim level for group 2 and 3 from 10% to 34% and activating the memory function for group 4:

   

  1. Turn all outputs OFF (= all orange LEDs are off).
  2. Press buttons 1 and 2 simultaneously. The red STATUS LED on the module will flash rapidly for 5 seconds, then start flashing at a slower rate.
  3. Once the STATUS LED begins to flash slowly, release one of the buttons, and 2 seconds later release the other button.
  4. The red STATUS LED continues to flash: the module is in learning mode.
  5. Press button 2 four times, press button 3 four times, press button 4 six times.

   

  If a second setting is desired, for a group you have already adjusted, take the module out of learning mode and go back into learning mode. Then make a selection again by pressing the button of the group to be changed the required number of times.

   

  We recommend aligning the minimum dim levels on Qbus with what the devices can physically handle. DALI devices are usually set to a minimum of 34%. If the devices have the “Dark dim” or “Dim to dark” function, the minimum dim levels can be much lower.

• System manager III

  Each modules has an unique serial number. By this number the System Manager recognizes the modules.

  This is completely explained in our knowledge center.

  The QDG04SA module has a built-in Dali power supply and can control up to 64 Dali1 I/O’s via 4 groups. This module can be controlled via the bus or Stand-alone via the inputs on the module itself.

  
  The groups can also be set via the System Manager: Assigning Dali addresses to a driver, configuring groups, setting parameters, etc. is done in the same way as with the QDM01.

  When entering the serial number and assigning the I/O’s, you will see, for example, the following screen:

  The 4 assigned I/O’s will control the 4 preset groups.
   

  The same as the other SA modules, this module can also work completely standalone. The settings as shown below are then applied.

  As with the other Qbus Stand-Alone modules, if the module is used in Stand-Alone mode, the fifth input (Input A: All Off/On) will act as an All Off button (press briefly), and as a Panic button at long push. As soon as the module is no longer used in Stand-Alone mode, i.e. if it is connected to a controller and is supplied with power via the bus, the fifth input will work differently. Now a scene must be created via the System Manager and assigned to this input (on the field “Input 5”). This scene is then executed with a short push. PLEASE NOTE, with a long press the next scene in the list of created scenes in the Qbus System Manager is automatically executed. So make sure that this is taken into account!

  IMPORTANT:
  - When several Stand-Alone modules are connected to each other on this fifth input, a scene may only be assigned to 1 module – the scene input (Input 5) must remain empty for all other connected modules!
  - For the scenes used in the 5th entrance of SA modules, NO DELAY TIMES may be set at the scene settings itself. The delays are entered in this module screen.
