Below is a list of features ( AKA site and installation issues) that the control system will report to the user. Although not limited to this list, the zencontrol system is able to monitor and advise of site issues and site conditions. Many of this diagnostics are invaluable for users and installers when it comes to finding and reporting issues.
If your controller has the Issues licence applied you may have some of the following issues reported.
Controller Issues
-
DALI short (Critical)
- Check there is a DALI power supply connected to the DALI line or if there are any shorts or devices causing the short on the line.
- the controller will check to see if the short has been removed, but after some time it will stop rechecking. If you get to this state, then you will need to power cycle the controller after repairing the short
- For LCM and RCM products the channel with the short will be disconnected allowing all other channels to function.
- Finding a DALI short on the line may be difficult. Normally this would be done by halving the DALI line until the short disappears, then add section by section. In some cases, the short can be in the light fitting.
-
Other controllers detected (Critical)
- It indicates that there is another zencontrol control system sending packets on the same DALI line.
- A second controller may have been plugged into the DALI line, contact your installer to remove the second controller
- Two DALI lines may have been connected together, contact your installer
- The DALI line may be incorrectly wired, contact your installer
- When another controller is detected both control systems will stop addressing new devices until the line is fixed. This will ensure that any previous commissioning will not be affected.
- It indicates that there is another zencontrol control system sending packets on the same DALI line.
-
Loopback detected on DALI line (Critical)
- It indicates that the DALI line has been looped back on itself. DALI supports star type typologies.
- Contact your installer to remove the looped connection
- It indicates that the DALI line has been looped back on itself. DALI supports star type typologies.
-
DALI transmit failure (Critical)
- It indicates the possibility that 2 or more of the channels on the control system have been connected together and damaged the system or
- Inbuilt DALI relay is unreliable or
- DALI signal relay is locked on.
- If a TX / RX failure is witnessed and you reboot the controller, the failure may revert to a dali short. This is because a failure to transmit or receive is more important than showing a dali short but if there is an initial dali short on boot, the controller will not attempt send dali, to begin with.
-
DALI receive failure (Critical)
- It indicates that the TX or RX circuit on the control system is likely broken, as it can not see its own transmission on the wire.
- The DALI line may be incorrectly wired, contact your installer
- Mains may have been applied to the circuit while the control system was running and been damaged
- Excess DALI current may have been applied to the system ( multiple DALI PSU or a connected current source like a led driver)
- If a TX / RX failure is witnessed and you reboot the controller, the failure may revert to a dali short. This is because a failure to transmit or receive is more important than showing a dali short but if there is an initial dali short on boot, the controller will not attempt send dali, to begin with.
- It indicates that the TX or RX circuit on the control system is likely broken, as it can not see its own transmission on the wire.
-
Startup stuck (Critical)
- Indicates the startup procedure is looping or stoped
- Possibility a DALI short has stopped startup
- An error on the DALI line
- a critical error
- Contact support with your issue
- Indicates the startup procedure is looping or stoped
-
Over current detected (Major)
- When using a zencontrol power supply you can get this error
- Indicated that the DALI line has too many devices connected and has passed the maximum current draw.
- On LCM and RCM devices the controller will disconnect some channels to remove the excess load and allow the other channels to continue to work
- This condition can occur when there is too much current draw from the DALI devices or in some cases a short on the dali line.
- When a LCM and RCM see this condition, they will retry isolated channels periodically for some time, however, after this time the LCM or RCM will not retry the channels until a power cycle.

-
Auto addressing disabled (Significant)
- There is at least one device that is continuously failing to be addressed. Quite often, this device will prevent the controller from addressing other unaddressed devices. After several failed addressing attempts, the controller will permanently disable automatic addressing and require user intervention.
- Right click on the Controller and choose "Search For New Devices". This will re-enable automatic addressing, as well as immediately attempt to address any devices on the line. This is always required to lift the addressing restriction.
- If auto addressing is found to be once again disabled, the device that is failing to address will need to be physically removed from the DALI line. Identifying all addressed devices on the bus will give a hint to which device this is, as it should not be addressed though this not always the case (occasionally, an actually addressed device will still mistakenly put itself in the addressing pool, causing further difficulties establishing the cause of the problem). Remember to right click and search for new devices to remove the restriction.
