      Error descriptionPossible causeAction
      The controller is in bulb mode. After switching the controller back on the light is flashing.The output current of the power supply is lower than the programmed current.
      1. Check if the desired current has been saved in the controller: Use the IY command with the option "W". For example type "IY 1000 W".
        If the desired current has not been saved the previously saved value or the default value is used.
      2. Check the output current of the power supply. The required current of the controller is 3.5 A per channel at full operation. For more information see (LINK).
      After setting a higher current the controller and the light switch off.The output current of the power supply is lower than the programmed current.Check the output current of the power supply. The required current of the controller is 3.5 A per channel at full operation. For more information see (LINK).

      The controller is in bulb mode. After switching the controller back on the brightness is different than before.The desired current has not been saved in the controller.Save the desired current in the controller: Use the IY command with the option "W". For example type "IY 1000 W". 
      The light does not switch on.The shutdown function is activated.
      There is no switch connected to the port.      		Check the error messages by using the command "ER".
      If the response is "ER 206" the shutdown function is activated. Follow the steps:
      1. Use the command "SD 0" to deactivate the shutdown function.
      2. Switch the controller off and on.
      3. Switch on the light.
      The light heats up but the fans do not start.The values of the command FC have not been saved in the controller.
      After setting the fan modes with the command FA the controller has not been switched off and on.
      1. Check and set the values of the switching temperatures by using "FC". For example type "FC 50,55 W".
      2. Check the fan modes by using the command "FA" and set correct values.
      3. Switch the controller off and on.
      During operation the light unexpectedly switches off. The housing is hot.The controller has switched off the light for safety reasons.Check the error messages by using the command "ER".
      If the response is "ER 205" follow the steps:
      1. Let the light cool down and switch it on.
      2. Check the correct heat sink selection for the current setting.
      3. Check the fans for correct operation.
      The temperature monitoring detects wrong or periodically changing values.EMC effects may affect the I2C communication. This happens primarily when using long cables, for example 10 m.Connect the shielding of the cable to ground.
      Perform a firmware update to version 5.1 or higher. Contact Chromasens support.
