Whenever work is done on the cabling of the Miniserver of any extensions please ensure that power to the installation is removed. Damage to components can occur if this is not observed.
NEVER WORK ON A LIVE PANEL
Before rebooting the extensions you should double check that all the connectors are plugged back in correctly and only then should you power up.
The blue Loxone Link connectors are especially sensitive to being plugged and unplugged if there is power to the devices. When working with the equipment please do not work on it powered up!
If you have an extension with a status LED flashing orange and that won’t show up in the search in Loxone Config or is showing as offline look at the following table for tips on how to solve the problem:
EXTENSIONS ARE NOT FOUND OR SOMETIMES GO OFFLINE?
1. Extension flashes orange
Check that the extension is connected to the correct serial number included in the program and stored in the mini server. Connect to your Miniserver and load out the PLC Config program. Now mark the peripheral tree the respective extension. In the properties window, the serial number is now visible and can be adjusted if necessary. The serial number of the extension can be found on the reverse side of the product.
Turn off the whole system for about 10 seconds by turning off the circuit breaker. The green terminal of Loxone devices (= power supply) must NOT be withdrawn if the power supply is active.
The Extension continues to flash Orange, switch off the power supply.
Now check whether the blue terminal is inserted correctly, or the wires have been clamped. Possibly a wire is broken, or the isolation was clamped.
If multiple power supplies are present, make sure that GND of all power supplies are connected. If this connection is not given, it can also lead to damage to the Loxone Link interface by potential differences between the power supplies.
Now take a resistance measurement device (e.g multimeter) to measure the resistance between the two poles of the Loxone links. (Between the two screws on the Link Terminal)
The resistance should be around 60 ohms.
Please refer to the above table for expected resistances across Miniserver links and GND.
Any divergences between their measured value, check if the Loxone link on the last extension with a 120 ohm resistor has been terminated, and the continuity of the line.
If no errors have been found, then measure the resistance of the individual Loxone Link pole to GND. Depending on the number of connected extension of the resistance value should be at least 1 to 50 ohms.
If this minimum resistance is met, connect the ohmmeter between GND and Loxone Link terminal. Tighten the Loxone link terminals (blue terminal) all extension sequentially from and keep you always display the ohmmeter in mind. Take one extension after another from Loxone link until the resistance increases by leaps and bounds. In this case, then there may be a defect of the respective extension that was just disconnected.
Please contact the support!
Now close again all extension to the Loxone link. After verifying that all connectors are inserted correctly, you can activate the power supply again.
If the problem still persists, please contact the support!
