Data logging
The EXXFIRE® 750CNF/1500CNF/2250CNF system logs data onto an onboard SD card to allow a
service engineer to analyse system performance. The SD card can hold data for 10+ years of
operation.
In case the SD card is missing or the system cannot access the SD card it will generate a Fault
condition and show fault code 11 on the 4-digit display of the UI panel.
Disconnected display
The EXXFIRE® 750CNF/1500CNF/2250CNF system detects when a display is not connected. When
the system detects this it will go in the fault state and try to display fault code LL. Since there is no
display available on the system itself, the system cannot display the fault code. However, if the
system is connected using the RS-485 interface, the other systems in the network will display this
fault.
If this fault appears, check the display cable on both sides of the connection, meaning in the user
interface box itself and the cable that is connected in the system to the electronics box. Be sure to
fasten the two screws on the connector!
If this does not resolve the issue, please contact ExxFire.
