Stand-Alone Universele dimmer 2/4 loads

• Function description

  1. This universal dimmer can operate both Stand-Alone (on its own – thus WITHOUT the Qbus Controller and WITHOUT external power supply), but can also be connected to a Qbus controller to become part of a complete Qbus home automation installation.
  2. The DIM02SA/500U is suitable for dimming two circuits of 10 – 500 VA. The dimmers are controlled digitally with 8-bit precision. An optical separation between inputs and outputs ensures the safe operation of the module. The dimmer can be used for incandescent lamps, halogen lamps, capacitive and inductive loads, dimmable 230V LEDs and dimmable fluorescent lamps.
  3. NOTE: Dimmable CFLs and dimmable LED lamps should be set to a minimum dim value (to be set with a cold lamp). Too low a dim value will significantly shorten the lifespan of these lamps or can cause flickering.
  4. If the dimmer is used as a Stand-Alone module, the load and minimum dim level can be chosen per output using the buttons on the module. See further under "Manual Operation" in this technical sheet. When using this dimmer in a Qbus installation with Controller, the load can be selected via the Qbus configuration software.
  5. The DIM02SA/500U is short-circuit proof, has overload protection and thermal protection. If the dimmer is triggered for protection due to short circuit, overload, or excessive temperature, the LED under the output will blink rapidly. The output can be reset by turning off the output. The DIM02SA/500U also has a built-in CAB filter. NOTE: Dimmable CFLs and dimmable LED lamps should be set to a minimum dim value (to be set with a cold lamp). Too low a dim value will significantly shorten the lifespan of these lamps or can cause flickering.
  6. If the dimmer is used as a Stand-Alone module, the load and minimum dim level can be chosen per output using the buttons on the module. See further under "Manual Operation" in this technical sheet. When using this dimmer in a Qbus installation with Controller, the load can be selected via the Qbus configuration software.
  7. The DIM02SA/500U is short-circuit proof, has overload protection and thermal protection. If the dimmer is triggered for protection due to short circuit, overload, or excessive temperature, the LED under the output will blink rapidly. The output can be reset by turning off the output. The DIM02SA/500U also has a built-in CAB filter.
  8. The module also has 3 potential-free inputs for connecting standard push buttons. Input 1 to 2 controls output 1 to 2 respectively, input A is a mood input that executes an ALL-OFF mood when pressed for 0.7 seconds (and then released), and a PANIC MOOD (All On) when pressed for 3 seconds (keep pressing). By default, the inputs are set as push buttons. When the DIM02SA/500U is connected to a controller, the function can be adjusted via the Qbus configuration software to normally open or normally closed.
  9. The module also contains 2 LED outputs for feedback on the switches. For this, an external 24V power supply must be installed.
  10. The dimmer outputs can only be programmed as a single-button dimmer. With a 1-button dimmer, the cycle must always be completed: starting from 0% to 100% and back to 0%. A short pulse (< 0.3 sec) brings the dimmer from zero to maximum in 2.5 seconds. The maximum value of the dimmer can be set between 5% and 100%. The output can also be automatically dimmed after a set time of 1 second to 255 minutes.
  11. If dimmers are controlled via a mood, the ascending time and descending time can be set independently between 0.3 seconds and 20 minutes.
  12. Each module has a unique serial number (6 digits). Based on this serial number  the module can be programmed via the Qbus software.
  13. Each DIM02SA/500U is fused with a 500mA fuse. Ensure adequate ventilation in the distribution box. A two-pole automatic circuit breaker of a maximum of 16A must be connected to the module power supply.

Installation and wiring

• Installation

  Snap the module onto a DIN rail DIN EN50022.

• Power Supply

  ATTENTION: DISCONNECT THE POWER SUPPLY TO THE MODULE BEFORE WORKING ON THE MODULE!
  A double-pole circuit breaker with a maximum of 16A must be connected to the 230Vac module power supply. Conductor cross-section: minimum 1.5mm². Strip approximately 7mm of insulation from the conductor and screw the conductor into the L-N connector.

• Load

  The dimmer is equipped with 2 or 4 dimming channels. The neutral conductor is internally looped through. 
  Connect the load as indicated according to the wiring diagrams. 

  Strip approximately 7mm of insulation from the conductors and screw the conductors into the connectors. For flexible wires, ferrules must be crimped onto the flexible wires before inserting them into the terminals. Use a flathead screwdriver of 0.5mm x 3mm to tighten the terminal screws. 

  Only switch on the power supply after all connections have been checked.

• SA Inputs

  If you wish to connect potential-free push buttons directly, you can connect them to inputs 1 to A. Strip approximately 7mm of insulation from the conductors and insert the conductors into terminals 1 to A. Both solid and flexible wire between 0.5 – 1.5 mm2 can be used; for flexible wire, you should carefully press the terminal spring with a screwdriver when inserting the wire. You can remove the wires from the terminals by pressing the top of the terminal and gently pulling the wire back without applying excessive force. 

• Stand-Alone LED feedback

  An external 5-24Vdc power supply can be connected to the DIM0xSA/500U to provide LED feedback for, for example, the directly connected push button(s).

• 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.

Wiring diagram

• Stand Alone

  Option 1: Stand-Alone with push buttons 

  Multiple DIM0xSA modules can be linked with each other or with other modules from the SA range (REL04SA, DIM04SA, ANR04SA).

  Option 2: Stand-Alone with LED feedback

  With additional 5-24V power supply for LED feedback on push buttons. 
  CAUTION! Never use the power supply of a Qbus controller for powering the LED feedback!

• With Qbus Controller

  With controller as part of a full Qbus system

  No module or switch needs to be replaced when a CTD is added to a Stand-Alone installation. All previously connected push buttons retain their function.

• SA-configuration

  MANUAL CONTROL:

  Used to directly control the outputs of the module or to select the connected load and the minimum dim-value if the dimmer is used in Stand-Alone mode. Each output can be controlled via the button under the respective output. To select the connected load, follow this procedure: 

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

  2)     Push both the buttons under output 1 and output 2 simultaneously for 4 seconds. 

  3)     The red STATUS LED on the module will flash fast during 5 seconds, and will then start to flash at a different speed. 

  4)     2 seconds after the STATUS LED has been flashing at a different speed, release one of the two buttons; 2 seconds later release the other one. The red STATUS LED will now continue to flash; the module is in configuration mode. 

  5)     The outputs are standard set for Conventional transfo’s. If other loads need to be dimmed, the respective load can be selected by pushing a number of times on the button underneath that output. The orange LED will lighten up each time the button has been pushed. See table below - next to the load type you will find the number of times the button of that output needs to be pushed:

  Load	Choise
  Conventional transformers	1
  Electronic transformers	2
  Incandescent lamps	2
  Halogen lamps 230V	2
  Retrofit led 230V (preferable)	2
  Retrofit led 230V (alternative)	1
  CFL with 100% startup (preferable)	3
  CFL with 100% startup (alternative)	4

  If no buttons have been pushed during 4 seconds, the module will get out of the configuration mode and the red STATUS LED will stop flashing. 

  6)     The minimum dim-level can also be set in Stand-Alone mode. Follow steps 1 to 4 above to get back in to the configuration mode. See table below to find out how many times the button needs to be pushed to select a certain minimum dim-level:

  Low Dimming Limit (DimMim)	choice
  0%	5
  10%	6
  20%	7
  30%	8

  If one of the buttons during configuration mode is pushed for 5 seconds, that output will be put back in to factory settings (= Conventional transformer and 10% minimum dim-level). A successfull RESET will be shown by 10 flashes of the orange LED of that channel.

  ATTENTION: : if you want to select a certain load for an output, and also select a minimum dim-level for this same output, you need to put the module in to configuration mode, select the load (push 1 to 4 times), get out of configuration mode, get back in to configuration mode and select the minimum dim-level (push 5 to 8 times).

   

  7)     The memory function means that the dimmer remembers what the set value was when turning the dimmer off. Example: If the dimmer is set to 60% on power off, the light will automatically turn on 60% when switched on. 

  See table below to find out how many times the button needs to be pushed to activate/deactivate the memory function:

  Memory function	Choice
  Memory fuction off	9
  Memory function on	10

• via 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 Dimmer Modules are used to control the input power for incandescent or halogen lamps, 230V LED lamps and energy-saving lamps. Each dimmer can be programmed as a 1 or 2 button dimmer. The one-button version allows you to reduce the number of control buttons, but remember that the dimming cycle must always be completed, from zero to maximum and back to zero. In the two-button version, you need a "+" and a "-" button, but you do not need to complete the full dimming cycle.

  When you hold down a key, the run time from 0 to 100% is 5.1sec. A short pulse (< 0.3 sec.) activates the dimmer in 2.5 sec. to 0 or to 100%. The minimum and maximum value can be set within a range from 0 to 100%, the start value if the “Dimmer-Daytime” is on and off from 5 to 100%. The start value must be 5% higher than the minimum value - that margin is automatically maintained when setting the minimum and start values. The lighting can also be dimmed automatically after a programmed period of 1 sec. up to 255 minutes (TimeOff). This automatic switch-off time only starts counting after activating the dimmer via a short pulse.

  If the dimmers are controlled via a scene, the rise and fall time can be set independently between 0.3 sec. and 20 min. This descent time is also used with the automatic shutdown.

  The I/O’s can be activated from the system manager using the Up / Down keys, and the current status can be consulted by pressing the "Read values" key.

  IMPORTANT: if a circuit dims dimmable energy-saving lamps, the option “CFL with 100% startup” must be selected in this window above. This ensures that the dimmable energy saving lamp is first ignited at 100%, and then dimmed to the requested percentage.
