If one or more Corona II modules are connected to the XLC4’s output channels, the associated channels are checked for open circuit failures during operation. An open circuit at a channel can only be detected if this channel is switched on.
If the XLC4 control unit is used with other LED modules than Corona II, the channel configuration is unknown to the XLC4 control unit.
Activate the channels in the ControlFlagsB that are to be monitored.
Example:
If ControlFlagsB=0x000E, the XLC4 control unit generates an error condition (err 203) when an open circuit condition is detected at channel C or channel D.
