TECHNICAL SPECIFICATIONS
CONNECTION OF OUTPUT 4-20 MA
CMeX30 can be connected to any passive current input that can handle
4-20 mA. Connect the signal cable for 4-20 mA to the left terminal of
screw terminal (3). Connect the negative cable (signal GND) to the
center terminal of screw terminal (3).
TROUBLESHOOTING
CMeX30 does not respond to M-Bus master commands
Verify your M-Bus slave configuration 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.
SAFETY
The warranty does not cover damage to the product caused by usage
in any other way than described in this manual. Elvaco AB can not be
