DESCRIPTION
Mini single-channel changeover relay module (for stand-alone and Velbus operation).
USAGE AND CONFIGURATION
The VMB1RYS can be used as a stand-alone changeover relay (with an external input for
switching the relay), or as part of a Velbus system (1 relay, 4 virtual relays, and 1
pushbutton channel).
A. Stand-Alone Mode (factory default)
By factory default, the VMB1RYS is in stand-alone mode. In stand-alone mode, a button
connected to the external input directly controls the relay. Select the operation mode
(toggle or pushbutton) using the MODE/TERM switch on the back (see instructions on
the module sticker). In "toggle" mode, the external input will control the relay in an ON-
OFF mode (each time the input is closed, the relay will switch from open to closed and
vice versa). In "pushbutton" mode, the external input will control the relay in an (ON)-
OFF mode (only while the input is closed, the relay is closed too, otherwise it remains
open).
STATUS LED:
• off: NO open, NC closed
• on: NO closed, NC open
• 3 flashes, pause, 3 flashes, etc.: supply voltage too low
PS LED: supply voltage detected
Rx-Tx LED: not applicable
B. Velbus Mode
To use the VMB1RYS as part of a Velbus system, connect it to a Velbus bus cable with at
least one other Velbus module and configure it using the Velbus configuration software
VelbusLink. (For more information on the Velbus system, go to www.velbus.eu.) By
changing the VMB1RYS's electronic address from FF(HEX)/255(DEC) to any other valid
value (01-253 DEC), Velbus mode is activated. In Velbus mode, the external input no
longer directly controls the relay, but instead both can be configured using the Velbus
configuration software VelbusLink. In Velbus mode, the MODE/TEMP switch on the back
selects the position of the CAN bus terminator (open or closed).
To return the VMB1RYS to standalone mode, reset the electronic address to
FF(HEX)/255(DEC) using the Velbus configuration software VelbusLink.
STATUS LED:
• off: NO open, NC closed
• on: NO closed, NC open
• slow flashing: timer is running
• 2 flashes, pause, 2 flashes, etc: communication error
• 3 flashes, pause, 3 flashes, etc.: supply voltage too low
PS LED: supply voltage detected
Rx LED: CAN bus package received
Tx LED: CAN bus package sent
