5.2 RESPONDING TO ALARM MESSAGES ON THE SCREEN
Alarm numbers, as well as DGN and PRM Nos., are those of the
FS16i-L.
See the conceptual diagram of alarm processing and a list of alarms in
an appendix of this manual.
ALM No.4061
A/D CONVERTER–1
Alarm output condition
This alarm is issued when the A/D converter 1 on the IF PCB does not
return the conversion completion signal in the specified time after the
start of conversion. This A/D converter is designed to read gas pressure
and power data.
Related data
DGN.981 Data when A/D1 conversion becomes abnormal.
No. Cause of trouble Solution
1 Poor connection in
communication
cable
Check the conductivity and connection of the
communication cable.
2 Anomaly of IF
PCB
Replace the IF PCB (A16B-2100-0142).
3 Anomaly of CNC
PCB
Replace the faulty PC board in the CNC.
ALM No.4062
A/D CONVERTER–2
Alarm output condition
This alarm is issued when the A/D converter 2 on the IF PCB does not
return the conversion completion signal in the specified time after the
start of conversion. This A/D converter is designed to read discharge
tube voltage and current data.
