Vent module for 3 groups LM3G
Flashing codes LM3G
Errors recognised are emitted as a flashing sequence via the yellow fault LED.
L = If the flashing codes is introduced by a long flashing signal, then the fault originates from another module.

Errors in detail
This list contains some typical errors and describes a suitable procedure for rectification. Not all possible faults can be
collated automatically, regular inspection and maintenance of the system is therefore necessary.
Continuous lights
This error can have two causes; either initialisation data is missing or the processor is not running.
Remedial Measures:
- Check that the address selector switch is on the correct address.
- Check if the MCU module has data for the address set, the module must be entered in the PC program
and have been configured.
- Wait for approx. 2 minutes until the MCU has transferred the current
initialisation data to a new module.
- Trigger system reset on the MCU module.
- If nothing helps replace the module.
Mains supply error: 1 times flash
This fault is signalled when a power supply unit has no 230 V supply voltage. The fault is visible for a
maximum of 15 seconds, after that the module switches into emergency operation.
Remedial Measures:
- See same error in the description of the power supply unit.
Bus error: 6 times flash
Communication with the MCM module is disrupted.
Remedial Measures:
- Check that the address selector switch is on the correct address.
- Check that the module is snapped onto the rail correctly.
- Check that the bus connector on the top hat rail is ok.
- Wait for approx. 5 minutes, in case the MCU initialises the communication again.
- If the error lasts for longer than 5 minutes, trigger a system reset on the MCU module.
- If nothing helps replace the module.
Self test: 8 times flash
The continuous self test has discovered an error in the program.
Remedial Measures:
- Send the module into the service department.
