6.5 Functionality
6.5.1 Power-up
After switching on the supply voltage, the XLC4 displays the stored device ID
1
by flashing the
3 status LEDs. The red LED has the valence of 10, the yellow LED 5 and the green LED 1.
Examples:
ID=3
green flashes 3 time while yellow and red are off
ID=7
green flashes 2 times while yellow is on
ID=13
green flashes 3 times while red is on
After signaling the device ID, the XLC4 checks the input voltage and the values of the
temperature sensors. Then the controller tries to access Corona modules connected to the 4
output channels. During this process, the red LED is on.
After a successful power-up, the green LED of the XLC4 is flashing with a period of 5 seconds.
Otherwise, the red LED is set.
After power-up, an identification string is sent over the serial interface. The string contains the
controller type and the loaded firmware version and release.

Device IDs are used to address dedicated XLC4 modules in a multi module RS485 bus structure.
