Troubleshooting
1) The device does not turn on (Power LED off)
- Check with multimeter that the supply voltage to the terminals (11) and (12) is
≃
40 V.
2) LED Overload on:
- If the LED is on without any communication (RX and TX LEDs do not blink), there is an overload caused
by a possible short-circuits between the two poles of the bus or from an excessive number of
connected devices. Check the wiring.
3) The datalogger connected to the terminal does not detect some or all devices:
- Check the correct bus connection between the datalogger and terminal G of the SIN.EQLC250
- Check with the multimeter that the voltage on devices not recognized is between 32Vdc-42Vdc
- Verify that the communication settings of the M-Bus datalogger or the SW are compatible with the
devices (speed of communication, addressing)
4) The devices connected to the level converter in repeater mode do not communicate:
- Check the correct power supply
- Check the Run LED is on
- Check that the Short Circuit LED is off
- Check that the M-Bus network is connected to the G terminal of the SIN.EQLC250
- Check the correct voltage in terminals G and H of the repeater which must be between 32 Vdc - 42 Vdc
