TROUBLESHOOTING
CMeX30 does not respond to M-Bus master commands
Verify your M-Bus slave conguration and connection:
• Voltage over M-Bus connection should be between 21 VDC and 42
VDC. Red LED will indicate error.
• All M-Bus slaves connected to the M-Bus master must have
unique primary addresses or secondary addresses depending on
addressing mode.
• Verify M-Bus slave baud rate used by M-Bus master. M-Bus master
baud rate must be identical to M-Bus slave baud rate.
CMeX30 cannot control the connected unit
Disconnect the cables to the unit to be controlled, e.g. the actuator.
Measure the output with a multimeter while an M-Bus command is
sent to change the output. If this works, there is probably an error in the
connection to the input of the unit to be controlled.
