8.7 Trouble-shooting
In these section typical problems and their solutions are described.
8.7.1 LED is blinking after repowering in bulb mode
Description:
After setting the controller to bulb mode and repowering the controller, the LEDs start to
blink.
Possible reason:
The power supply is too weak for the programmed current.
Solutions:
1. Check whether the desired current has
been saved by using the “W” option with the
IY command. (e.g. IY 1000 W). Otherwise the last saved value or the default value is
used.
2. Check the power supply for correct output range. The XLC4 needs approx. 3.5 amps
per channel at full operation. For more information, see section 6.4.2.
8.7.2 LED is starting with a different brightness in bulb mode
Description:
After repowering the controller in the bulb, the brightness is different than before at
setting up the controller.
Possible reason:
The value for the current has not been saved to the controller.
Solutions:
Use
the “W” option of the “IY” command to save the desired brightness/current to the
XLC4 controller, e.g. IY 1000 W.
8.7.3 LED cannot be switched on
Description:
Even with correct settings for operation mode the LEDs are not switched on.
Possible reason:
Shutdown function is activated, and no switch is connected to the port.
Solutions:
Check the error states by using “ER”. If the response is “er 206”, the shutdown function is
activated. Use the command “SD 0” to deactivate the shutdown function. Repower the
controller and try again to switch on the LEDs.
