Troubleshooting

Symptom

Possible indication

(on the front panel of the dimmer)

Possible Causes

Solution

Reduced brightness observed in the dimmer channel outputs

Channel Indicator: Slow Flash, Yellow

• Channel is operating at reduced setting due to over temperature condition

• Normally due to excessive load and/or inadequate ventilation and/or high operating temperature

• Reduce the load on the channel and/or total the load on the unit

• Improve enclosure ventilation to reduce the temperature of the enclosure

Dimmer Channel does not work

Channel Indicator: Fast Flash, Yellow

• Channel shutdown due to over temperature condition

• Normally due to excessive load and/or inadequate ventilation

Channel Indicator: Fast Flash, Red

• Channel shutdown due to over current

• Normally due to excessive inrush or load/wiring fault (short circuit)

Check the wiring, rectify the issue and then turn on the dimmer to restore it to its normal operating state

Dimmer does not work

Unit Indicator: Slow Flash, Red/Yellow

Internal temperature has exceeded over-temperature threshold

Improve enclosure ventilation to reduce ambient temperature

Unit Indicator: Slow Flash, Red/Green

Unit Over temperature

Unit Indicator: Red

Stored configuration is not compatible with firmware version Can occur after a major firmware version update

Redeploy the configuration of the dimmer via the SpaceLogic C-Bus Commission software

Dimmer ignores C-Bus commands

C-Bus indicator: Solid Red

No C-Bus clock detected

Enable C-Bus system clock generator

Unit Indicator : Blinking

Override is active

Cannot Turn On the channel

Channel Indicator: Solid Red

Channel Offline Normally due to no mains supply to channel bank Example: The breaker has tripped or the supply has not been connected If not all channels in the bank are affected, it could be the result of a failed channel firmware update

• Ensure the wiring is done according to the instruction sheet Check breakers if banks have independent circuit protection

• If failed firmware update suspected, re-perform the channel firmware update with the SpaceLogic C-Bus Commission software

Cannot turn ON/OFF the C-Bus Power supply from the front panel

Not applicable

Power Supply Toggle from the front panel is disabled by the Software

Change the configuration of the dimmer via the SpaceLogic C-Bus Commission software to enable C-Bus power supply toggle from indicator buttons

Can not enable/disable the C-Bus clock from the front panel

Not applicable

System Clock Toggle from the front panel is disabled by the Software

Change the configuration of the dimmer via the SpaceLogic C-Bus Commission software to enable System Clock toggle from indicator buttons

No C-Bus Power

Unit Indicator: OFF

No mains power supply

Advise to check mains voltage

C-Bus cable not connected

Advise to check C-bus cable

Jumper link not fitted for 110 V

Advise to check the connection

Low Voltage

C-Bus indicator: Steady Flash

Overload on the network

Enable C-Bus Power supply in additional units

C-Bus indicator: Short Flash

Low mains voltage

Advise to check mains voltage

Voltage drop over long distance of cable run

Low voltage indicator - LED provided installer training

Reduced brightness observed in the channel outputs

Not applicable

Warn before off is activated

Expected behavior if warn-before is enabled

Mixing the loads

Check for load uniformity

Error message after switching ON the dimmer channel

Error message after switching ON the dimmer channel

Incorrect dimming mode

Use the channel button to change to LE mode

The lights are flickering

Not applicable

The default load profile might not be suitable for this light

Customize the load profile and dimming curve to achieve the desired dimming outcome

Lights can be non-dimmable light sources

Ensure the load that is connected to the dimmer is a dimmable load

If it occurs at specific times, usually in the evening, there maybe ripple signalling on the grid

Choose a different type of lamp which is less affected by ripple, or install a ripple filter

Cannot find the dimmer on the C-Bus network

Not applicable

Unit is in bootloader state

Cycle the power on the dimmer to exit bootloader

Unit Indicator: OFF

No mains power supply

Check there is mains power to the unit

C-Bus cable not connected

Check that the C-bus cable is connected properly

Jumper link not fitted for 110 V

Check that the 110 V wire link is connected properly

It is difficult to set the brightness level at the bottom or top end of the dimming

Not applicable

The default 1:1 dimming curve may not be suitable for the loads profile

Customize the load profile and dimming curve to achieve the desired dimming outcome

Lights flashes brightly at start up

Not applicable

The default load profile is not suitable for the load or incorrect setting for Kick-start

• Customize the default load profile with minimum and maximum brightness to make the lighting behavior suitable with the load

• Ensure there is no incorrectly configured Kick-Start parameter set

The lights do not turn on at lower brightness level set by C-Bus

Not applicable

The default load profile is not suitable for the load

Customize the default load profile with minimum and maximum brightness to make the lighting behavior suitable with the load Consider configuring Kick-Start

Dimmer does not work after firmware update

Not applicable

Interruption during firmware update

• Check the condition of the USB communication cable used between the laptop and the device and ensure good quality cable is used for firmware update, or try a shorter cable Ensure update process is not interrupted, and wait for software to confirm process is complete before removing the cable

  Check the USB cable connection and ensure it is fully inserted in the USB-C connector

• If instructed by the software press the reset button for recovery purposes
