DESCRIPTION

With this module it is possible to dim lamps operating on mains voltage. Also suitable for dimming low voltage lamps in combination with a wire-wound iron core transformer.

PROPERTIES

Use:

 Required mains voltage: 220...240V/50Hz  Suitable to control incandescence or halogen lamps on mains voltage  Suitable to control low voltage halogen lamps in combination with a dimmable wire-wound iron core

transformer

 Suitable for some types of dimmable LED lamps on mains voltage

Output:

 Maximum load: 400W @ 230V/50Hz  Leading edge phase control  Slowly switching on and off (ca. 1.5s) will prolong the life span of the lamp  Dimming from 0 to 100% in ca. 4 seconds  Power grid distortion (EMI) conform EN55015

Protection:

 Built-in non-resettable: 4A slow  Verification of too inductive loads (holding current triac). This protection can be disabled for some types of

lamps e.g. dimmable lamps

 Thermal protection:

o When temperature reaches 80°C, light output is reduced to 25% of the desired value o When temperature reaches 90°C, the lamp is switched off o Thermal protection is switched off when temperature drops below 60°C o Tolerance on thermal protection: ±4°C

LED indications:

 Status of the dimmer:

o Continuous on: desired dimming value reached o Slow flash: timer running o Fast flash: dimming value changing o Two short flashes: communication error detected o Three short flashes: not possible to dim load with this dimmer o Four short flashes: temperature alarm (light output reset to 25% of desired value) o Five short flashes: thermal protection (lamp is switched off)

 Presence of input voltage  Sending and receiving Velbus data  Report status to control modules

Module power:

 Required input voltage: 12...18Vdc  Consumption in stand-by: 28mA@18Vdc  Maximum consumption: 30mA@18Vdc

Dimensions:

 Standard DIN-rail housing: 2 modules wide  Length x width x height: 90 x 36 x 58mm

Configuration:

 Only configurable via Velbus PC interface (VMB1USB, VMB1RS or VMBRSUSB) and the VelbusLink

software

 Software addressing (up to 250 possible addresses)  Storage capacity for 37 different pushbuttons and their function  Multiple functions and time settings can be set via software  Learned pushbuttons are maintained during power outage

VMBDMI Dimmer manual – edition 1 3

Operation:

 Local operation on the module (on/off when short push, dimming when push and hold)  Via Velbus commands or pushbuttons connected to the Velbus system  Various operation functions:

o Momentary o Off or slowly off o On or slowly on o On/off or slowly on.off o Timer (start/stop, resettable or non-resettable o Dim (more or less light output) o More light output o Less light output o Evoke atmospheres o Multiple step dimmer o Forced off o Forced on o Suppress

Time settings:

 Only settable via the VelbusLink software  Switch-off time adjustable between:

o 1 sec ... 2 min, increment 1 sec o 2 min ... 5 min, increment 15 sec o 5 min ... 30 min, increment van 30 sec o 30 min ... 1 hour, increment 1 min o 1 hour ... 5 hours, increment 15 min o 5 hours ... 10 hours, increment 30 min o 10 hours ... 24 hours, increment 1 hour o 2 days o 3 days o No switch-off time

 Dimming speed adjustable between:

o 2 sec ... 2 min, increment 1 sec o 2 min ... 5 min, increment 15 sec o 5 min ... 30 min, increment 30 sec o 30 min ... 1 hour, increment 1 min o 1 hour ... 5 hours, increment 15 min o 5 hours ... 10 hours, increment 30 min o 10 hours ... 23 hours, increment 1 hour

VELBUS CHARACTERISTICS

 2-wire communication for Velbus data + 2 wires for power supply  Data transmission rate: 16.6 Kbit/s  Serial data protocol: CAN (Controller Area Network)  Short circuit protected (both towards ‘+’ and ‘-‘ of the power supply)  Bus error indication: 2 short flashes of the indicator LEDs  Self repairing after 25 seconds when a bus fault occurs

Each dimmer can be given a name of up to 16 characters (max.).

The dimmer module can send following messages:

 Dimmer status  Module type: dimmer module (including software version)  dimmer name  Communication fault counter  Memory content

The dimmer module can send following commands:

 Turn off LEDs on a control module  Turn on LEDs on a control module  Make LEDs flash slowly or fast on a control module

The dimmer module can receive following commands:

 The status of a pushbutton module  The status of a slider button

The dimmer module can receive following commands:

 Set dimmer value  Return to last used dimming value  Stop dimming  Start timer  Forced off  Cancel forced off  Forced on  Cancel forced on  Suppress  Cancel suppress  Request dimmer status  Request type of module and software version  Request communication fault counter  Request dimmer name  Request memory content  Overwrite memory content  Clear pushbutton indication LED
