7.3.8 Auxiliary O2/Air Module Runtime Alarms 
Aux O2/AIR 
Comm Stop 
High 
The communication 
between the CPU board 
and auxiliary O2/air 
module stops. 
The CPU board lost 
communication with the 
auxiliary O2/air module 
for 10s. 
1. Restart the auxiliary O2/air module. 
2. If the status screen has a 
communication stop alarm, or encounters 
the black or blank screen error, rectify 
the fault of the status screen first (refer to 
7.2.1). 
3. If the problem persists, remove the 
auxiliary electrical outlet (refer to 8.1.2) 
and service door (refer to 8.1.1), 
reconnect the cable between the auxiliary 
O2/air module and the backplane 
(backplane socket position: "O2Air" 
socket on the right). 
4. If the problem persists, replace the 
auxiliary O2/air module (refer to 11.1.4).
