State
Description
Steady light
Normal operation
Infrequently flashing light (2Hz)
No communication
Frequently flashing light (10Hz)
Too low supply voltage
Two short pulses every 2 seconds
Microcontroller memory failure. In such case it is
necessary to upload firmware or repair the expander.
2.3 Power supply
The XM-6DR requires 12VDC nominal power supply. If the voltage is below ~10V then the module
stops its operation, deactivates all relays and signals the error by means of LED Power indicator
(blinks 10 times per second).
Note: For proper communication by means of RACS Clock& Data bus it is required to connect all
GND terminals of devices. Such requirement is satisfied if both devices are supplied from the same
point. If devices are supplied from different power supply units then GND terminals of
communicating devices must be connected by means of separate wire in order to equalize
potentials. Any wire section can be applied.
2.4 Module mounting
XM-6DR module is not adapted to outdoor operation and it is installer responsibility to apply proper
method and location for module installation.
Note: If any relay output of XM-6DR is used for switching 230VAC, then special
precautions must be taken and all installation works must be performed by qualified
and certified installer.
Fig. 3 XM-6DR relay terminals
Note: Single COM terminal is associated with two NO terminals (see fig. 3). Therefore it is
necessary to ensure that sum of currents for particular pair of NO terminals does not exceed 10 A.
